Introduction

The first National Health and Nutrition Examination Survey was started in April 1971 and completed

in June 1974. Measures of nutritional and related

general health status for a probability sample representative of the civilian noninstitutionalized population of the United States 1-74 years of age were

collected by means of this program. Of the approximately 28,000 persons selected, 74 percent or 20,749

of those sampled were examined.

There was oversampling done at known rates for

those persons believed to be at high risk of malnutrition. This category consisted of those with low

incomes, preschool children, women of childbetig

age, and the elderly. Adjusted sampling weights were

later computed within 60 age, sex, and race categories

to inflate the sample so that it reflected the U.S.

population at the midpoint of the survey, Information on the general health status of the entire age

group as well as more detailed health assessment data

on those 25-74 years of age was obtained through the

program. At 65 survey locations, a dental examination was given to the entire sample that was examined. After the nutrition survey was completed, the

detailed examinations, excluding the dental examination given to the age groups 25-74 years, was

continued until October 1975 at 35 additional

locations.

Information about each sample person examined

during the first National Health and Nutrition Examination Survey was obtained by means of a household

interview; a general medical history; a 24-hour dietary

intake recall interview; a food frequency interview; a

food program questionnaire: a general medical examination; dental, dermatological, and ophthalmological

examinations; anthropometric measurements; and 24

hematological, blood chemistry, and urological laboratory determinations. Also, hand-wrist X-rays were

taken on those 1-17 years of age.

Additional information was collected from the

subsample of adults aged 25-74 years by means of the

following questionnaires, procedures, and measurements: a medical history supplement; three supplementary questionnaires concerning artluitic, resptiatory, and cardiovascular conditions for those with

symptoms; a health care needs questionnaire; a

general well-being questionnaire; an extended medical

examination; X-rays of the chest and hip-sacroiliac

and knee joints; audiometry; electroczudiography;

goniometry; spirometry; pulmonary diffusion and

tuberculin tests; and additional laboratory determinations. A detailed description of the specific content

of the survey, plan of operation, and sample design is

provided in the following reports: Plan and Operation

of the Health and Nutrition Examination Survey,

Series 1, Nos. 10a and 10b.1Z2

This report contains national estimates of the

number of decayed, missing, and ffled teeth among

persons 1-74 years by-age, sex, race, and other selected

demographic characteristics. In the tex~ and tables that

follow, the occurrence of decay among specified

groups is described by citing the mean number of

decayed (D), missing (M), and ffled (F) teeth per

person found among them. In several instances, DMF

findings from this survey are also compared with those

of the three previous national surveys-the fmt among

adults aged 18-79 years in 1960-62, the second among

children aged 6-11 yearn in 1963-65, and the third

among youths aged 12-17 years in 1966-70.35 The

DMF teeth are defined as the total number of

permanent teeth that are decayed, f~ed, and either

missing or indicated for extraction (nonfunctionalcarious). Children, youths, and young adults rarely

lose teeth because of periodontal disease, but many

frequently lose teeth because of neglected decay.

Teeth are also lost as a result of accidents or are

extracted because of crowding. Thus when the teeth

lost by these young people for reasons other than decay

are excluded from the DMF counts, the DMF index

accurately records the number of permanent teeth

that have been attacked by decay at least once.

1
On the other hand, older adults often lose teeth

from severe periodontal disease that progressively

destroys the structures supporting the teeth in the

jaw. Therefore, among older men and women whose

missing teeth may never have had decay, the DMF

index merely provides a summation of the lifetime

toll of all dental disease.

The number of primary teeth present and previously attacked by decay is indicated by the mean

number of decayed (d), nonfunctional-canous (e),

and filled (f) primary teeth per child for children 1-11

years of age. The def index does not include missing

teeth because the results of cross-sectional surveys

such as the first National Health and Nutrition

Examination Survey (NHANES I) do not show

whether missing primary teeth were decayed before

they were either shed or extracted. Thus the def

index provides a count of the number of primary

teeth present at the time of examination that had

been attacked by decay at least once.

The components of both the DMF and the def

index-decayed (untreated), ffled, and missing or

nonfunctional teeth-are also presented by specified

demographic characteristics. Each component is an

indicator of the relative adequacy or inadequacy of

professional dental care received. Specifically, a large

F or f component reflects favorably on the adequacy

of previous care whereas, by contrast, relatively large

D or d and M or e components indicate lower levels

of care. Statistically significant differences between

estimates of persons aged 1-74 years as well as

observed differences (which may be of interest even

though they may not be statistically significant) are

discussed. Statistically significant differences are

clearly labelled.
When 20,749 people in a national probability

sample of the United States civilian noninstitutionalized population were examined by dentists in

1971-74, it was found that:

An estimated 20 percent of children 1-5 years of

age had at least one untreated decayed primary

tooth.

An estimated31 percent of children 6-11 yean of

age had at least one untreated decayed permanent

tooth.

An estimated 54 percent of youths 12-17 yerms of

age had at least one untreated decayed permanent

tooth.

An estimated 47 percent of adults 18-74 years of

age, with at least one natural tooth, had at least

one untreated decayed permanent tooth.

Children aged 1-5 years averaged 1.0 decayed,

nonfunctional-carious, and ffled primary tooth

per child. Of these, 0.7 were untreated decayed

teeth.

Children aged 6-11 years averaged 1.7 decayed,

missing, and ffled permanent teeth per child. Of

these, 0.7 were untreated decayed teeth.

Youths aged 12-17 years averaged 6.2 decayed,

●

●

●

missing, and ffled permanent teeth per person. Of

these, 1.8 were untreated decayed teeth.

Adults aged 18-74 years, with at least one ntitural

tooth, averaged 16.9 decayed, missing, and ftied

permanent teeth per person. Of these, 1.4 were

untreated decayed teeth.

There was no change in the average number of

decayed, missing, and ffled teeth among children

between 1963-65 when the National Health

Examination Survey (NHES) Cycle II was conducted and the 1971-74 survey.

There was no change in the average number of

decayed, missing, and ftied teeth among youths

between 1966-70 when the National Health

Examination Sumey Cycle III was conducted and

the 1971-74 survey.

An improvement among adults between 1960-62

when the National Health Examination Survey

Cycle I was conducted and 1971-74 was indicated. Young adults aged 18-24 years had, on the

average, 2.3 fewer missing teeth in 1971-74 than

in 1960-62. About 3-4 percent fewer adults aged

45-74 were edentulous in 1971-74 than in 1960-

62. On the average, adults aged 35-74 years who

still retained some of their natural teeth had 2

more ffled teeth in 1971-74 than in 196G62.
Primary teeth

National estimates of the average number of

decayed, nonfunctional-carious, and filled primary

teeth per child in the United States in 1971-74 by

age, sex, and race are found in tables 1 and 2. For

children 1-5 years of age, for all races, the average

number of def teeth increased with advancing age

from a low of Ofor children 1 year of age to a high of

2.2 per child for those 5 years of age. The average

number of def teeth for children aged 6-11 years

declined with advancing age from a high of about

four for children 7 and 8 years of age to a low of

about one per child for those 11 years of age. White

boys had about the same average number of def teeth

per child as white girls for children 1-5 years of age

(1.0 compared with 0.9) and for children 6-11 years

of age (3.0 compared with 2.7). The average number

of def teeth per child was also about the same for

black boys and girls 1-5 years of age (figure 1). No

sex difference was observed in the average number of

def teeth for black ctidren 6-11 years of age.

The average number of def teeth per child did not

differ by race for children 1-5 years of age. For

children in the age category 6-11 years, however, the

average number of def teeth per child was higher for

white than for black children (2. 8 to 2.1, respectively). White boys had higher averages at every single

year of age than black boys. White girls also had

higher def scores at every single year of age, except

those 6 years of age, when compared with black girls.

There was very little difference by sex in the average

scores of any def component. The percent distribution of children 1-5 years of age by specified number

of def teeth according to sex is shown in table 3. The

number of primary teeth present is shown by age,

race, and sex in table A.

years ofage (table 4andfigure 2). Missing permanent

teeth were relatively few, adding only a small fraction

to the DMF scores.

Table 5 shows the percent distribution ofch.ildren

byspecified number of DMFand D,M, and Fteeth.

Anestimated45 percent of children aged 6-11 years

had no DMF teeth, and about one-fourth had either

one or two DMF teeth. Although the remairing

children had three or more DMF teeth, relatively

few–about 3 percent–had more than five DMF teeth.

Additionally, 69 percent of all children aged 6-11

years had no untreated decayed permanent teeth in

contrast to about 5 percent with four or more

untreated decayed teeth. Approximately 92 percent

of the children had no missing permanent teeth, and

about 69 percent had no ffled permanent teeth.

Among the 24.6 million U.S. youths aged 12-17

years, the estimated mean number of DMF teeth per

person was 6.2 (table 6). The estimate consists of 1.8

decayed, 0.6 missing, and 3.7 ftied permanent teeth.

The average number of DMF teeth increased steadily

with advancing age—3.8 for youths 12 years of age,

compared with 8.7 for those 17 years of age. The

more than twofold increase in the number of DMF

teeth per person among youths reflects similar increases in all three DMF components—decayed,

missing, and fflled teeth. The D and F components

are about twice as great for youths 17 years of age as

for youths 12 years of age. The M component is more

than three times as great for those 17 yearn of age as

for those 12 years of age. The proportion of each

component in the DMF index does not vary appreciably with age: between 25 and 36 percent of the

average DMF count per person for every given age are

D teeth, about 10 percent are M teeth, and about 60

percent are F teeth.

The percent distribution of youths aged 12-17

years with specified numbers of DMF teeth is shown

according to sex in table 7.

per child among children 6-11 vears of age, bv age and sex: United

States, 1971-74-

Several estimates in the table indicate that most

youths visit their dentists in time to have any teeth

affected by decay treated. For instance, about 68

percent of the youths had at least one filled tooth,

and a little over one-third had as many as five or

more. In addition, 46 percent had no untreated

decayed permanent teeth.

On the other hand, other estimates in the table

point out the failure of many youths either to receive

dental care or to receive it as early as they should.

First, about 28 percent of the youths had at least

three untreated decayed teeth and 13 percent had

five or more. Next, about 26 percent of the youths

5
had at least one tooth that was classified as missing

because of canes. Finally, although only about

one-tenth of all youths had never had a decayed

permanent tooth, about one-third of all youths had

no filled teeth. Therefore, about one out of every five

youths has at least one tooth that needs filling or at

least one that is classified as missing.

Dentulous adults aged 18-74 years averaged 16.9

DMF teeth per person (table 8). This DMF score

consists of 1.4 decayed, 7.4 missing, and 8.1 fflled

teeth. The DMF teeth increased consistently with age

from a low of 10.7 for the youngest group of men

and women to a high of 22.2 for the oldest group.

An estimated 14.7 percent of the adult population aged 18-74 years have lost all of their permanent

teeth. k additional 9.2 percent have lost all their

upper or lower teeth (table 9). Tooth loss in an

entire arch increases steadily with advancing age:

Only about 4 percent of those 18-44 years of age

have lost all their teeth and 6 percent have lost an

entire arch, compared with about 45 percent and 15

percent, respectively, for those 65-74 years of age.

More women than men 18-74 years of age have lost

all their teeth– 15.8 percent, compared with 13.3–

and more women than men have an edentulous

arch– 10.2 percent, compared with 8 percent. Tables

10 and 11 present the significant differences in the

percent of tooth loss by race.

The percent distribution of dentulous adults

18-74 years of age with specified numbers of DMF

teeth and the components of the DMF index are

shown according to sex in table 12.

Sex. –The average number of decayed, missing,

and filled permanent teeth per child varied slightly by

sex among children aged 6-11 years (table 4). Girls on

the average had more DMF teeth per child than boys

of the same age. The average DMF for girls 6-11 years

of age is 1.7, compared with 1.5 for boys 6-11 years

of age.

The average number of erupted permanent teeth

per child for children aged 6-11 years is shown by

age, race, and sex in table B. At every given year of

age boys had fewer erupted teeth than girls.

Girls had more DMF teeth per 100 erupted

permanent teeth than boys (table 13). Of every 100

erupted permanent teeth among girls aged ,6-11 years

an estimated 12.1 were decayed, missing, and filled;

the proportion among boys was 11.6 per 100 teeth.

The average number of DMF teeth per person

differs according to the sex of youths 12-17 years of

age (table 6 and figure 3). The overall index for black

males 12-17 years of age was not significantly lower

than the corresponding counts for black females. The

average DMF score for all males aged 12-17 years and

the score for white males aged 12-17 years were

significantly lower than the DMF scores for corresponding females. The average DMF counts for

males of all races at 14, 15, and 17 years of age were

significantly lower than the corresponding counts for

females at those ages.

Among youths, the higher DMF counts for

females can be attributed largely to the differences in

the number of missing and fdled teeth according to

sex (table 6). The differences in the average scores for

both the M and F component were statistically

significant.

permanent teeth per youth are presented in table C,

Figure 3. Average number of decayed, missing, and filled (DMF) teeth

per person among youths 12-17 years of age, by age and sex: Unitad

States, 1971-74

Among those 12-17 years of age, females had

more DMF teeth per 100 erupted permanent teeth

than males-24.2 and 20.9, respectively (table 14).

The average number of DMF teeth per person

among dentulous adults differs according to sex.

Women without exception averaged higher DMF

counts than men of the same age (table 8 and figure

4). The differences were statistically significant for

most age groups. The exceptions were young adults

aged 18-24 yea-s and adults aged 55-64 yearn.

Women had more missing and ffled teeth than

men. The differences in the averages for both

components were statistically significant. Men had

more decayed teeth than women. This difference,

although fractionally small, was also statistically

signitlcant. Adding edentulous persons to the DMF

index does not reverse the trends observed for age or

sex (table 15).

Race. –Table 4 and figure 5 reveal no significant

differences in the number of DMF teeth by race for

children 6-11 years of age. The slight observed

difference can be attributed to the larger number of

decayed and misstig teeth per child among black

children.

Differences in the average number of DMF teeth

per youth 12-17 years of age show little consistent

association with race (table 6). Average DMF counts

for white males except those 13 and 14 years of age

were higher than the counts for black males of the

same age and sex. The estimates for white females

were higher than those of black females at ages 13,

16, and 17 years. Differences between estimates of

the DMF components for white and black youths

occur consistently and in some cases are statistically

significant (figure 6). Although white youths had

about twice as many decayed and missing teeth as

white youths had.

The DMF counts of white adults were consistently higher than those for black adults. The

average number for white adults was 17.5, compared

with 13.3 for black adults (table 8). The observed

difference was statistically significant. This difference

can be attributed to the fact that white adults had

four times as many ffled teeth as black adults–8.9

number of DMF teeth as families with incomes of

$7,000 or more.

Among chddren 6-11 years of age whose parents

attained the same level of education (table 17), the

average number of DMF teeth per child for girls was

9
slightly greater than for boys through the fust 11

years of completed parental education. For those

children whose parents had a high school education

or more, differences between boys and girls in this

measure of dental health were generally negligible,

There was no significant difference in the average

number of fdled permanent teeth per child among

white children across the various levels of parental

education.

The estimates in tables 18 and 19 did not indicate

an association of DMF teeth with family income or

with the educational levels of the parents of youths

aged 12-17 years. Estimates did, however, differ

slightly but consistently by race and sex of the

youths. On the average within each level of income,

white females had slightly higher DMF counts than

white males. Black females had slightly higher average

DMF counts in all but one income category when

compared with black males. Within all but two levels

of income, white males had somewhat higher counts

than black males and white females had slightly

higher counts than black females. Within all levels of

education mean DMF counts for white females

consistently exceeded those for white males. Black

females had slightly higher average counts than black

males across all but two levels of educational attainment. No consistent pattern by race was observed for

educational levels.

A significant association of DMF components

with income and education was found among adults

(tables 20 and 21). The average number of ffled teeth

per person increased with level of education, while

the average of M and to a lesser extent D teeth

decreased. Adults with the most education had higher

DMF scores. Within just about every level of education and at every level of income white men had

higher DMF scores than black men and white women

had higher DMF scores than black women,

Geographic region of residence. –Estimates of the

average number of DMF teeth per child by sex, race,

and region are found in table 22. Children 6-1 II years

of age living in the Northeast had slightly higher DMF

counts per child than those living elsewhere, Children

living in the West had the lowest counts, chilc[ren in

the South had more decayed and missing teetlh than

those in other regions. These children also had fewer

ffled teeth than those in other regions.

Table 23 contains estimates of the average number of DMF teeth per person for youths aged 12-17

years by race, sex, and region. Youths living in the

Northeast had significantly higher DMF counts than

those living elsewhere. The average number of DMF

teeth per person among white and black youths; living

in regions other than the Northeast did not differ

significantly.

The average numbers of D, M, and F teeth per

youth by region are also found in table 23. Youths of

all races living in the South had higher numbers of D

and M teeth than those living elsewhere and a

significantly higher number than those living IkIthe

West. Youths in the Northeast had significantly

higher estimates of F teeth than those living elsewhere.

Adults residing in the Northeast consistently had

significantly higher DMF estimates than those living in

other regions (table 24). Those living in the’West had

consistently lower DMF estimates than those living

elsewhere.

Comparison with

previous nationalsurveys

The fimt three National Health Examination

Surveys in 1960-70 that were briefly described earlier

and the succeeding National Health and Nutrition

Examination Survey in 1971-74, whose dental

findings are presented in this report, were designed to

provide information from highly representative

samples of the U.S. civilian noninstitutionalized

population. The dental i-indings collected by all four

surveys consisted for the most part of counts of

decayed, missing, and ffled teeth and indexes for

evaluating the prevalence and severity of periodontal

disease and the status of oral hygiene. In addition, the

occlusion of the teeth of children 6-11 years of age

was assessed during the 1963-65 survey, of youths

12-17 years of age during the 1966-70 survey, and of

children and youths 6-21 years of age during the

1971-74 survey.

As plans were being considered in 1959 for the

first survey’s dental examination it was realized that

examining and later reexamining identical subgroups

of the U.S. civilian noninstitutionalized population in

a series of continuing surveys would enable the

National Center for Health Statistics (NCHS) to

measure the changes in the prevalence and the

outcome of disease on a national scale (e.g., whether

an increasing proportion of decayed teeth were being

treated). As a result, it seemed especially desirable to

collect the findings of the succession of surveys that

were being anticipated in as standardized a way as

possible. The dentists selected to examine during the

fmt survey, and in the ones that followed it, were,

therefore, trained to follow the same procedures

throughout as well as the same definitions and

criteria. In addition, these dentists were assessed by

the same two senior dentists and retrained and

reassessed by them from time to time. Hence, the

surveys’ findings are as comparable as possible.

Howevel, despite these precautionary measures, it

was realized that the surveys’ findings wouId reflect

some degree of examiner variability and the periodontal disease and oral hygiene findings were more

susceptible to observer variability than counts of

decayed, missing, and ffled teeth.

The anticipated return to previously examined

segments of the U.S. civilian noninstitutionalized

population took place in 1971 when NHANES I

began. That survey’s sample included persons aged

6-74 years-the same age groups examined in one or

another of the earlier surveys. The intervals between

the midpoint of NHANES I (1972) and those of the

survey of adults (1961), of children (1965), and of

youths (1968) were about 11, 7, and 4 years,

respectively.

During the last three decades a number of

preventive measures aimed at reducing the incidence

of dental decay have met with growing acceptance by

the American public. Foremost among them is the

adjustment of the fluoride content of community

water supplies (figure 7). Since 1954, when Grand

Rapids, Michigan, became the first community to

fluoridate its water supply, the number of Americans

living in communities with fluoridated water has risen

to more than 94 million persons (1975 ),6 This

number does not include 10.7 million persons Wing

in areas where fluoride occurs naturally in the water.

Other dental health practices and procedures that

have affected the teeth of millions include the

following: the prescribing of fluoride tablets by

dentists and pediatricians; topical fluoride applications; the use of dentifrices containing fluorides; and

most recently, the supervised and unsupewised use of

rinses containing fluoride.

What has been the effect of these preventive

measures on the dental health of Americans? Do the

findings of the successive nationwide surveys shed

any light on whether the incidence of tooth decay in

the U.S. population at large is indeed decreasing? Is it

sti too early to expect the effect of fluoridation to

affect the national estimates of the mean DMF counts

of adults?

As the estimates in table D show, the average

DMF count per person for children 6-11 years of age

11
and youths 12-17 years of age did not change

significantly during the periods from National Health

Examination Survey (NHES) II (1963-65) and NHES

III (1966-70) to NHANES I. However, the mean

counts for the surveys are quite low, which probably

reflects the reduced incidence of decay that has

occurred during the past few decades. Unfortunately,

no comparable national counts of DMF teeth exist

from surveys that were completed before community

water fluoridation began to significantly lower the

incidence of decay. Ordy the findings of surveys

conducted on children in fluoridated communities

can now give some indication of what may have

occurred throughout the Nation. For example, the

1964 findings on Illinois youths 13-17 years of age

reported that those who drank fluoride-deficient

water all their lives averaged 9.0 DMF teeth. Those, on

the other hand, who drank only fluoridated water

averaged 4.2 DMF teeth.T It is believed that the

average reduction in the number of decayed teeth

resulting from drinking fluoridated water is about 50

percent.e

The DMF counts compiled by Suomi in 19789

from selected surveys over the preceding 40 years

probably give a rough indication of the extent of the

recent reduction in tooth decay experienced by

children 6-16 years of age. The average number of

DMF teeth per person are plotted in figure 8 for

children in fluoridated and nonfluondated areas. This

figure includes comparable estimates from NH[ES 11

and III.

For children 6-9 years of age, NHES estimates are

about the same as those compiled from selected

surveys conducted in fluoridated areas. The :NHES

estimates for older children are between, but slightly

closer to those from fluoridated areas than to those

from nonfluoridated areas. About one-half of the 40

primary sampling units in the NHES II and III

samples had fluoridated water supplies at the time of

the surveys.

The component counts of the NHANES DMF

estimates show no important changes from those of

the preceding surveys that would be considered

clinically significant. Of the estimates being compared, the average number of decayed teeth left

unffled showed little or no change. This finding was

also true for both ffled and extracted or nonfunctional-canous teeth.

If the effects of water fluoridation and other

means of reducing decay appear at all in the DMF

findings of the national surveys, one would expect to

see it in the DMF counts of young adults 18-24 years

of age. Those pecsons in this age group examined

during 1960-62 were born in 1942+4, before communities had begun to fluoridate their water supplies.

By 1953, when this age group was 11 or 12 years of

age, only about 10 million Americans were drinking

fluoridated water. Because all permanent teeth except

third molars are usually erupted by 12 years of age,

the teeth of very few of even the youngest adults

examined in the 1960-62 survey would be expected

to show an increased resistance to decay due to

fluoridated water.

On the other hand, young adults 18 years of age

examined during the NHANES I were born in the

years 1953-56, a 4-year interval when the population

who had access to fluoridated water systems increased by 15-25 million persons. During the decade

that ended in 1965, the population who had access to

fluoridated water systems had reached almost 60

million persons. Therefore, while more young adults

exarnineda in NHANES I could have had access to

fluoridated water systems as the enamel of their

permanent teeth was being formed, there was still a

majority of the population who did not have access

to fluoridated water systems.

The average number of DMF teeth per person and

the component counts are shown in table E for men

and women 18-34 years of age in 1960-62 and

1971-74. In the emlier survey young men and women

aged 18-24 years had about two DMF teeth more

than those of comparable age in the later survey. For

men and women 25-34 years of age, however, the

DMF estimates of both surveys are about the same.

The 1971-74 survey estimates for both young

men and women aged 18-24 years were 17 percent

under those of the 1960-62 survey. The reduction

was due almost entirely to the smaller number of

teeth classified as “missing.” Because most of the

teeth classi15ed as “missing” have been extracted,

counts of M teeth are subject to very little examiner

error. It seems reasonable to assume, therefore, that

the incidence of tooth decay in U.S. young adults was

lower in 1971-74 than in 196F)-62.

The DMF and M estimates in table E include

teeth missing not only because of decay but also for

other reasons such as accidents and orthodontic

extractions, which are excluded from other tables in

this report. As a result, the NHANES I estimates in

table E range from 0.6 to 1.1 higher than comparable

estimates either cited in the text or shown in other

tables. All missing teeth are added to the NHANES I

estimates because teeth missing for reasons other than

decay cannot be subtracted from the NHES I

estimates.

Many older adults lose a significant number of

their teeth because of bone loss, due to advanced

periodontal disease, and prosthetic considerations.

Therefore, the count of DMF teeth after 35 years of

age is not an accurate record of the number of teeth

attacked by decay. The DMF components, on the

other hand, may indicate changes or trends in the

amount and type of dental services that have occurred during the intervals between surveys.

An important improvement in the dental health

of older adults has occurred throughout the Nation

during the past two decades: Americans can now

expect to keep their teeth longer than in previous

years. For example, in 1957-58, the average number

of years young adults 20 years of age with natural

teeth could expect to live before losing their last

teeth was 39.7. In 1971, the expected dentulous

lifetime of young adults 20 years of age increased to

42 years. 10 These averages are based on findings from

two surveys conducted by the National Health

Interview Survey (NHIS) on probability samples of

U.S. households.

The trend toward keeping one’s teeth longer is

also reflected in the differences between the estimated percent of edentulous persons in 1960-62 and

1971-74 (table F). Notably, the percent based on the

NHANES I findings differ but little from those based

on the 1971 NHIS findings.

The 1960-62 and 1971-74 DMF findings are

shown in table G. The average number of decayed,

missing, and fdled teeth in adults 35-74 years Iof age

was about one tooth higher in the most recent survey

than in the earlier one. The number of teeth that

older adults had had filled increased during the years

since the frost NHES—avera@ng about two mm-e for

men and one more for women. The estimates of D

and M teeth for the two surveys showed little change.

In summary, a comparison of the average DMF

counts of U.S. children 6-11 years of age examined in

surveys about 7 years apart and of U.S. youths 12-17

years of age examined about 4 years apart showed

that no clinically important change had occumed in

the prevalence of tooth decay during the interwds

between the surveys. However, indications of a recent

improvement in the dental health of U.S. adults were

found. The percent of those 45-74 years of ag,ewho

were edentulous was about 3 or 4 percent less ti

1971-74 than in 1960-62. In addition, adults 34-74

years of age who had not lost all their teeth averaged

about 2 f~ed teeth more in the later survey than in

the earlier one. Finally, the average DMF count for

young adults 18-24 years of age was about 2 teeth

lower in 1971-74 than in 1960-62. The intensive

effort that was made dutig the last two decades has

now begun to appear in the U.S. population at lzrge.

The DMF index is a good indicator of the

prevalence of dental caries; however, it does not

indicate the need for other kinds of dental care. The

Institute of Medicine (IOM) recently published a

reportl 2 outlining public policy options for better

dental health. The IOM study includes estimates from

the NHANES conducted in 1971-74 as well as data

from other National Health Examination and

National Health Interview Surveys.

Discussion

The estimates presented in this report give statistical data concerning the prevalence and distribution

of decayed, missing, and filled teeth among the U.S.

civilian noninstitutionalized population 1-74 years of

age. The dental component in this survey, NHANES

I, upon which the national estimates are based is the

fourth of its kind conducted by the National Center

for Health Statistics. The NHANES I data were

collected over a 3-year period from April 1971 to

June 1974. Essentially the same procedures as those

in the previous three National Health Extiation

Sumeys were used. The same two senior dentists

trained and sometimes retrained the other eight

dentists who collected most of the dental findings.

Measures were taken to control the amount of

interexaminer variability and to obtain findings comparable to previous surveys.

The average number of DMF teeth per person for

the U.S. civilian noninstitutionalized population 644

years of age is plotted by age in figure 9. The average

number of teeth per person affected was higher at

each age from 6 through 27 years. The rising trend is

observed to continue during ages 27-44 years, but the

rate of increase is slower than in the earlier ages.

Estimates for adults over 44 years of age are not

shown because of the large proportion of teeth lost

either because of periodontal disease or other

reasons.

The DMF components are iko plotted by age in

figure 9. The average number of decayed teeth per

person follows the same pattern noted in the earlier

surveys, which is a slight ticrease during childhood

and adolescence, and then a leveling off around 14

yearn of age. This pattern lasts through 25 yews of

~geafter which the D counts start to decline.

The M counts (average number of missing teeth

per person) increase slowly during ages 6-17 yem,

but from then on the increase is more rapid. The M

component contains only third molars that had been

extracted because of decay. A difference in the data

from the initial NHES among adults and the later

NHANES I was evident because in NHES I the M

component included third molars that were absent

for any reason.

The F component (average number of ffled teeth

per person) also shows a sharp upward climb until

about 21 years of age after which it begins to slow.

At about 35 years of age, the number of filled teeth

per person begins to decline.

Continuity of the trends in DMF teeth between

the surveys, as evidenced in NHANES I, demonstrates

the uniformity of the dental examinations. Many of

the trends and differences noted were associated with

the same demographic variables throughout the population. However, there were findings that did not

prevail consistently during childhood, adolescence,

and adulthood. These conditions were noted earlier in

the text.

Because dental caries are a lifelong threat to

dental health, the estimates of decayed, missing, and

ffled teeth are important. The differences in the

prevalence of tooth decay as measured by DMF teeth

demonstrate the need for dental care by various

demographic characteristics. There was no significant

association except by age. However, associations of

ffled teeth with increasing income, and decayed and

extracted teeth with decreasing income are important

indicators of the levels of dental care throughout the

population.

Children 1-5 years of age in the United States

averaged one decayed, nonfunctional-carious, and

ffled primary tooth per child as estimated from

dental examination findings in the National Health

and Nutrition Examination Survey of 1971-74. There

were increases with advancing age among the preschool age group in each of the components of the

def index. The average number of def teeth for

children 6-11 yearn of age was 2.7. However, witi

the age group 6-11 years there were decreases with

advancing age in each of the components of the def

index. The decrease in the older age group was related

to the decrease in the number of primary teeth at risk

to decay.

Children 6-11 years of age averaged 1.7 decayed,

missing, and fdled permanent teeth per child. &

estimated 31 percent of these children also had at

least one untreated decayed permanent tooth. Youths

12-17 years of age averaged 6.2 decayed, missing, and

ffled permanent teeth per person. i% estimated 54

percent of these youths had at least one untreated

decayed permanent tooth. Among dentulous adults

18-74 years of age, there were on the average 16.9

decayed, missing, and fidled permanent teeth per

person.

The estimates are based on standardized dental

examinations conducted during 1971-74 on 20,749

persons 1-74 years of age. These persons were from

the probability sample selected to represent the

noninstitutionalized civiLian population of those ages

who lived in the United States at that time. There

were observed differences in the prevalence of decayed, missing, and ffled permanent teeth among

persons 6-74 years of age according to their sex. Both

white and black males 6-17 years of age were

observed to have lower DMF counts per person than

females of the same race. The DMF index for males

6-11 years of age was 1.5. whereas that for females of

comparable age was 1.7. Comparing the DMF index

for youths 12-17 years of age, males averaged 5.7 and

females averaged 6.7. &nong dentulous adults 18-74

years of age, the comparison between the sexes was

16.4 among men and 17.4 among women.

The average number of decayed, missing, and

ftied permanent teeth also differed by race. Among

those persons 18-74 years of age, white persons had

signi.i3cantly higher DMF indexes than black persons.

Among youths 12-17 yeas \of age, the difference

between scores, although not statistically significant,

were higher. Black and white children 6-11 years of

age had about the same average number of DMF teeth

(1.7 and 1.6, respectively). White children, however,

had about twice as many F teeth per child as black

children (0.9 and 0.5, respectively) and fewer D (0.6

and 0.9, respectively) and M (O.1 and 0.3, respectively) teeth.

White youths 12-17 years of age had about four

times as many F teeth per person as black youths (4.1

and 1.3, respectively). White persons 18-74 years of

age also averaged about four times as many F teeth

per person as black persons (8.9 and 2.3, respectively). White youths had about half as many D ( 1.6

compared with 3.1) and M (0.6 compared with 1.4)

teeth as black youths. White adults had about half as

many D teeth per person as black adults, but only

about one M tooth fewer.

The number of decayed, missing, and fdled

permanent teeth was not associated with either

family income or education or, in the case of those

6-17 years of age, with the parent’s education. The

components of the DMF index, however, were

associated with these variables.

Persons 6-74 years of age living in the Northeast

had higher DMF counts than those living in the other

regions. The differences, however, were not statistically significant. The average component scores also

showed some regional variations.

There were no clinically important changes in the

prevalence of tooth decay during the intervals between the earlier surveys of children in 1963-65 and

youths in 1966-70 when compared with the same age

groups in the 1971-74 survey.

Appendix L Statistical notes

‘Thesurvey design

The sampling plan for the first 65 stands of the

National Health and Nutrition Examination Survey

(NHANES) followed a stratified multistage probability design in which a sample of the civilian

noninstitutionalized population of the coterminous

United States, 1-74 years of age, was selected.

Excluded from the selection were persons residing in

Alaska and Hawaii and those within the coterminous

United States confined to institutions or residing on

reservation lands of American Indians. Successive

elements dealt with in the process of sampling were

the primary sampling unit (PSU), the census enumeration district (ED), the segment (a cluster of households), the household, the eligible persons, and finally

the sample persons.

The starting points in the f~st stage of this design

were the 1960 Decennial Census lists of addresses and

the nearly 100 PSU’S into which the entire United

States was divided. Each PSU is either a standard

metropolitan statistical area (SMSA), a single county,

or two or three contiguous counties. The PSU’S were

grouped into 357 strata as they were for use in the

National Health Interview Survey (NHIS) during

1963-72 and subsequently collapsed into 40 superstrata for use in NHANES and in Cycles II and III of

the National Health Examination Survey (NHES).

Fifteen of the 40 superstrata contained a single

large metropolitan area of more than 2,000,000

population. These 15 large metropolitan areas were

selected for the sample with certainty. The 25

noncertainty strata were classified into four broad

geographic regions of approximately equal population

and crossclassified into four broad population density

groups in each region. Then a modified GoodmanKish controlled selection technique was used to

select two PSU’S from each of the 25 noncertainty

superstrata with the probability of selection of a PSU

proportionate to its 1960 population so that pr~

portionate representation of specified State groups

and rate of population change classes were maintained in the sample, In this manner a total first-stage

sample of 65 PSU’S was selected. These 65 sample

PSU’S or stands were the areas within which a sample

of persons would be selected for examination cwer a

3-year survey period.

Although the 1970 Census data were used as the

frame for selecting the sample with PSU’S when they

became available, the calendar of operations required

that 1960 Census data be used for 44 of the 65

stands in the sample of NHANES. The ED’s in each

PSU were divided into segments of an expected six

housing units each. In urban ED’s the segments were

clusters of six addresses from the 1960 Census Listing

Books. For ED’s not having usable addresses, area

sampling was employed and, consequently, some

variation in the segment size occurred. To make the

sample representative of the current population of

the United States, the address or list segments were

supplemented by a sample of housing units that had

been constructed since 1960.

Within each PSU a systematic sample of segments

was selected, The ED’s that fell into the sample were

coded into one of two economic classes. The fmt

class, identified as the “poverty stratum,” was composed of “current poverty areas” that had been

identified by the U.S. Bureau of the Census in 1970

(pre-1 970 Census), plus other ED’s in the PSU with a

mean income of less than $3,000 in 1959 (based on

1960 Census). The second economic class, the “non- .,

poverty stratum, “ included all ED’s not designated as

belonging to the poverty stratum.

All sample segments classified as being in the

poverty stratum were retained in the sample. For those

sample segments in nonpoverty stratum ED’s, the

selected segments were divided into eight random

subgroups and one of the subgroups was chosen to

remain in the NHANES sample. This procedure permits

a separate analysis with adequate reliability of those

classified as “being below the poverty level” and those

classified as “being above the poverty level. ”

42
After identification of the sample segments, a list

of all current addresses within the segment boundaries was made, and a person in each of the households

was interviewed to determine the age and sex of each

household member, as well as other demographic and

socioeconomic information required for the survey.

To select the persons in sample segments to be

examined in NHANES, all household members aged

1-74 years in each seg-nent were listed on a sample

selection worksheet with each household in the

segment listed serially. The number of household

members in each of the six age-sex groups shown

below were listed on the worksheet under the

appropriate age-sex-group column. The sample

selection worksheets were then put in segment

number order and a systematic random sample of

persons in each age-sex group was selected to be

examined using the following sampling rates.

The persons selected in the 65-stand sample of

NHANES made up a representative sample of the

target population and included 28,043 sample

persons 1-74 years of age of whom 20,749 or 74.0

percent were examined. When adjustments were made

for differential sampling for high-risk groups, the

response rate became 75.2 percent.

All data presented in this report were based on

“weighted” observations. That is, data recorded for

each sample person were inflated to characterize the

subuniverse from which that sample person was

drawn. The weight for each examined person was a

product of the reciprocal of the probability of

selecting the person, an adjustment for nonresponse

cases (i.e., persons not examined), and a poststratified

ratio adjustment that increases precision by making

the f?mal sample estimates of the population agee

approximately with independent controls prepared

by the U.S. Bureau of the Census for the noninstitutionalized population of the United States as of

November 1, 1972 (approxkate midsurvey point),

by race, sex, and age shown in table I. Population

estimates are included in some of the tables in greater

detaiI than that used for weighting. These population

figures, although not precise census estimates in this

degree of age detail, ae included to give a rough idea

of the number in the population at risk.

A more detailed description of the survey design

and selection technique can be found in the “Plan

and operation of the Health and Nutrition Examination Survey, United States, 1971-1973.” Vital and

Health Statistics, Series 1, No. 10a-1

Nonresponse

In any health examination survey, after the

sample is identified and the sample persons are

requested to puticipate in the examination, the

survey meets one of its more severe problems. Usually

a sizable number of sample persons will not participate in the examination. Whether or not an individual

participates is determined by many factors, some of

which me uncontrollable and, therefore, may be

reasonably treated as an outcome of a random event

with a particular probability ~f occurrence. In this

situation, the effect of nonparticipation would only

be to reduce the sample size, thereby increasing the

sampling errors of examination findings. In practice,

however, a potential for bias due to nonresponse

exists if participation is not a random event and if

nonparticipants differ from participants. Because of

the possibilities of bias, intensive efforts were made in

NHANES to develop and implement procedures and

inducements that would reduce the number of

nonrespondents and thereby reduce the potential of

bias due to nonresponse. These procedures and

inducements are discussed in the “Plan and operation

of the Health and Nutrition Examination Survey,

United States, 1971-1973,” Series 1, No. 10a. 1

Despite these intensive efforts, 24.8 percent of

the sample persons from the 65 stands were not

examined. Consequently, the potential for a sizable

bias does exist in the estimates in this publication.

From what we know about the nonrespondents and

the nature of nonresponse, we believe that the

likelihood of sizable bias is small. For instance, only a

small proportion of persons gave reasons for nonparticipation that would lead to the belief that they

would never agree to participate in examination

surveys and that they may differ from examined

persons with respect to the characteristic under

examination. Only 15 percent of the nonrespondents

gave as their reasons for nonparticipation personal

illness, physically unable, pregnant, anti-doctor, or

fear of finding something wrong. Typical reasons

given by the other nonrespondents were unable

because of work, school, or household duties;

suspicious or skeptical of the program; not interested

in participating; and private medical care sufficient or

just visited doctor.

An analysis of medical history data obtained for

most nonexaminees as well as examinees also supports the belief that the likelihood of sizable bias due

to nonresponse is small. No large differences were

found between the examined and the nonexamined

groups for the statistics compared. For example, 11

percent of persons examined reported having an

illness or condition that interferes with their eating as

compared with 9 percent of persons not examined

but who had completed a medical history. The

percent of persons examined reporting ever being told

by a doctor that they had arthritis was 20 percent;

the percent for high blood pressure was 18 percent

and for diabetes, 4 percent. The corresponding

percents for ncmexarnined persons were arthritis, 17

percent; high blood pressure, 21 percent; and diabetes, 4 percent.

As mentioned previously, the data in this report

are based on weighted observations, and one of the

components of the weight assigned to an examined

person was an adjustment for nonresponse, A procedure was adopted that multiplies the reciprocal of

the probability of selection of sample persons by a

factor that brings estimates based on examined

persons only up to a level that would have been

achieved if zdl sample persons had been examined.

This nonresponse adjustment factor is the ratio of the

sum of sampling weights for all sample persons within

a relatively homogeneous class deftied by age, sex,

and five income groups (under $3,000;

$3,000-$6,999; $7,000-$9,999; $10,000-$ 14,999;

and $15,000 and over) within each stand to the sum

of sampling weights for all responding sample persons

within the homogeneous class for the same stand. To

the degree that homogeneous groups can be defined

which are also homogeneous with respect to the

characteristics under study, the procedure can be

effective in reducing the potential bias from nonresponse, For the 65-stand sample of NHANES, the

percent distribution of the nonresponse adjustment

factors used for the 325 income group-stand ceflk is

shown in table IL

Missing data

Examination surveys are subject to the loss of

information not only through the failure to examine

all sample persons, but also from the failure to obtain

and record all items of information for examined

persons. Dental findings were obtained and recc)rds

were available for 20,218 of the 20,749 examinees in

this NHANES I program. Those 531 whose dental

records were lost or not obtained through examinations were assigned imputed values as described in the

following section. These imputed values are included

in the detailed tables and findings of this report. The

age-sex distribution of the examinees is shown in

tables III and IV.

Imputation

Imputation of dental findings for an exarninee

was done by randomly selecting a match with the

dental findings from among the group of exarninees

of the same age in years, race, sex, and income group

with information recorded. The findings of this

“matched” examinee were then used as the imputation for the exarninee with missing data. When alata

for the income variable was not available, the match

was limited to age in years, race, and sex.

Reliability of estimates

Because the statistics presented in this report are

based on a sample, they will differ somewhat from

the statistics that would have been obtained if the

survey had been conducted on the complete population. In other words, the statistics are subject to

sampling variability.

The standard error is primarily a measure of

sampling variability, but may also include part of the

variation that arises in the measurement process. The

standard errors presented in tables 1-24 have been

calculated by a technique referred to as “balanced

repeated replication.” The need for this specialized

technique for estimating standard errors has arisen

because of the complexity of the sample design of

NHANES Iwhich makes it inappropriate to calculate

them by a technique that does not account for the

complex sample design (see Vital and Health Statistics, Series 2, No. 1413). It must be noted that

estimates of standard error are themselves subjec~ to

errors that may be large if the number of cases upon

which the estimates are based is small.

Small numbers

In some tables magnitudes are shown for cells for

which the sample size is so small that the sampling

error may be several times as great as the statistic

itself. Obviously in such instances the numbers, if

shown, have been included to convey an impression

of the overall story of the table.

Sampling and measurement error

In this report, reference has been made to efforts

to minimize bias and variability of measurement

techniques. The potential of residual bias due ro the

high nonresponse rate has also been discussed.

The probability design of the survey makes

possible the calculation of sampling errors. Traditionally, the role of the sampling error has been the

determination of how imprecise the survey results

may be because they come from a sample rather than

from the measurement of all elements in the universe.

The estimation of sampling errors for a study of

the type of the Health and Nutrition Examination

Survey is difficult for at least tlmee reasons: (1)

measurement error and “pure” sampling error are

confounded in the data–it is difficult to fmd a

procedure that W either completely include both, or

treat one or the other sep~ately, (2) the survey

design and estimation procedure are complex and,

accordingly, require computationally involved techniques for the calculation of variances, and (3)

hundreds of statistics are presented in the tables in

this report, many for subclasses of the population for

which there are a small number of sample cases.

Estimates of sampling error are obtained from the

sample data and are themselves subject to sampling

error when the number of cases in a cell is small or,

even occasionally, when the number of cases is

substantial.

In this report, estimates of the standard errom for

selected statistics used are presented in most of the

tables. Readers are again reminded that these esti45
mated sampling errors do not reflect any residual bias

that might still be present after the attempted

correction for nonresponse. The standard error is

primarily a measure of sampling variability, that is,

the variations that might occur by chance because

only a sample of the population is surveyed. As

calculated for this report, the standard error also

reflects part of the variation that arises in the

measurement process. It does not include estimates of

any biases that might lie in the data. The chances are

about 68 out of 100 that an estimate from the sample

would differ from a complete census by less than the

standard error. The chances are about 95 out of 100

that the difference would be less than twice the

standard error and about 99 out of 100 that it would

be less than 2?4times as large.

Tests of significance

‘ The procedure used in this report for testing the

significance of the difference between the two means

consisted of dividing the difference between the two

means by the standard error of the difference; that is,

a z statistic was computed. An approximation of the

standard error of a difference d = x - y of the two

statistics x and y is given by the formula

where SX and SV are the sampling errors, respectively,

of x and y. Of course, where the two groups or

measures are positively or negatively correlated, this

will give an overestimate or underestimate, respectively, of the actual standard error.

Statistical significance of differences indicated in

the text are based on 0.05 significance levels except

for differences among regions. For regional differences the 0.01 significance levels were used. Other

text statements of substantively important differences and age-related trends based on national

estimates from this cross-sectional sample data belc)w

these levels of statistical significance are referred to as

“observed” differences.

46
Appendix IL Demographic and

socioeconomic terms

Age.–Two ages were recorded for each exarninee:

the age at last birthday at the time of the examination and the census interview. The age criterion for

inclusion in the sample used in this survey was

defined as age at the time of census interview. The

adjustment and weighting procedure used to produce

national estimates was based on the age at interview.

Data in the detailed tables and text of this report are

shown by age at the time of the examination, except

for those who became 75 years of age at the time of

the examination who are included in the age group

65-74 years.

Race. –Race was recorded as “white,” “Negro,”

or “other.” “Other” includes Japanese, Ctiese,

American Indian, Korean, Eskimo, and all races other

than white and black. Mexicans were included with

“white” unless their race was definitely known to be

hencan Indian or of a race other than white. Black

persons and those of mixed black and other parentage

were recorded as ●’Negro,” but are referred to as

black in this report. When a person of mixed racial

background was uncertain about his race, the race of

lus father was recorded.

Geographic re@”on.–The 48 contiguous States and

the District of Columbia (excluding Alaska and

Hawaii) were stratified into four broad geographic

regions, each of about the same population size. With

a few exceptions the compositions of the regions

were as follows:

Reaion Sta sw itmlud?d

Northeam . . . Mainer New Hampshire, Vermont, Masse.

chusetts, Connecticutr Rhoda Island, New

York, New Jersey, Pennsylvania

Midmst . . . . Ohio, Michigan, Indiana, Illinois, Wisconsin,

Minnesota, low, Missouri

South . . . . . . Delaware, Maryland, Virginiar Wast Virginia,

Kentucky, Arkansas, Tennessee, North

Carolina, South Carolina, Gaorgia, Florida,

Alabama, Mississippi, Louisiana, District of

Columbia

Region States included

West . . . . . . . Washington, Oregon, Idaho, Montana,

Wyoming, Colorado, Utah, Nevada, California, Arizona, New Mexico, Texas, Oklahoma, Kansasr Nebraska, South Dakota,

North Dakota

In a few instances the a~tual boundaries of the

regions did not follow State hnes. Some strata in the

Midwest and South include primary sampling units

(PSU’S) actually located in the West. Similafly, some

strata in the West contain PSU’S located in the

Midwest and South.

Family income. –The income recorded was the

total income received during the 12 months prior to

the interview by the head of the household and all

other household members related to the head. This

income was the gross cash income (excluding pay in

kind) except in the case of a family with its own farm

or business. In that instance net income was recorded.

Also included was the income of a member of the

A-rned Forces living at home with his family (even

though he was not considered a household member).

If he was not living at home, allotments and other

money received by the family from him were

included in the family income figure.

Education. –The only grades counted were those

attended in a regular graded public or private school

where persons were given formal education, whether

during the day or at night, on a fulltime or part-time

attendance basis. A “regular” school is one in which a

person is advanced toward an elementzuy or high

school diploma, or a college, university, or professional school degree. Education received in vocational, trade, or business schools outside the regular

school system was not counted in determining the

highest grade of school completed. If a person

attended school ti a foreign country, at an ungraded

school. under a tutor, or under other special circumstances, the nearest equivalent of his highest grade

attended was given.

47
Appendix Ill. The dental examination

The examhation

The dental examination findings were recorded

on a form that eliminated the time-consuming task of

coding and keypunching. The form (figure I), four

pages bound at the left-hand margin, was fed into an

Optical Mark Page Reader that read the findings and

entered the data directly on IBM cards.

Instructions for determining the conditions of

individual teeth and recording the information were

as follows:

1.

2.

3.

4.

5.

6.

7,

Primary tooth present–A primary tooth was

coded as “D,” and its status was also coded.

Permanent tooth present–only the status of a

pemument tooth was coded.

Normal-Unfdled teeth without carious lesions

were coded as “3.”

Carious-Unfilled teeth with carious lesions were

coded according to the surfaces involved.

Fdled (including crown) -Teeth with satisfactory

fillings and no carious lesions were coded according to the surfaces involved.

Filled defective (or tooth both fdled and

carious)-Filled or crowned teeth with new or

recurrent carious lesions were coded according to

the surfaces involved. Noncarious filled teeth

were coded in the same way when the restoration

was loose, or fractured, and the base or pulpal

wall of the cavity preparation was exposed. Teeth

with temporary fdlings or crowns were coded as

filled defective,

Nonfunctional-canous-when decay had penetrated the pulp chamber of a tooth, the tooth was

coded under “XD.” Ca@ous teeth were nonfunctional when there was:

a. Visible evidence of a penapical abcess or

pulpal exposure,

b. Visible evidence of extensive undermining of

all enamel walls or if roots only were remaining.

Retained deciduous teeth–When any portion of

the succedaneous tooth could be seen, it was

given an appropriate status code under teeth

present and also coded “XD” and “D.”

Missing teeth (unerupted, extracted, and replaced) –When neither a primary nor a permanent

tooth was present (the tooth space may have been

vacant or the missing tooth may have been

replaced by a fixed or removable partial denture),

a code was recorded indicating the status of the

tooth space. For persons under 35 years of age,

the reason that the tooth was missim should hawe

been determined. When there

scored as missing because of

decay. The cocles

2 = Unerupted, primary

O= Unerupted, permanent

IR = Extracted, canes

1 = Extracted, accident, orthodontics, impaction

F = Missing, replaced on a fixed bridge, The

reason for extraction was also coded if the 

sample person was under 35 years of age.

FD = Missing, replaced on a defective fu.ed

bridge. The reason for extraction was also 

coded if the sample person was under 35

years of age.

Fixed bridges were defective:

A.

B.

When one of the abutment teeth was nonfunctional because of either cties or loss of supporting structure, or when there was visible

evidence of periapical pathology.

When the connection of the pontic with its

abutment was broken.

C. When an abutment crown or inlay was defective

because of one of the following reasons:

1. The tooth structures exposed by abrasion of

the crown or inlay were carious.

2. A canous lesion at one of the margins of the

restoration had resulted in extensive undermining of an enamel wall.

The Periodontal Index (PI)

Scores were assigned according to these criteria:

O–Negative. There is neither overt inflammation in

the investing tissues nor loss of function due to

destruction of supporting tissues.

1–Mild gingivitis. There is an overt area of inflammation in the free gingivae, but the area does not

circumscribe the tooth.

2–Gingivitis. Inflammation that completely circumscribes the tooth, but there is no apparent break in

the epithelial attachment.

6–Gingivitis with pocket formation. The epithelkd

attachment has been broken and there is a pocket

(not merely a deepened gingival crevice due to

swelling in the free gingivae). There is no interference with norrmd masticator function; the

tooth is firm in its socket and has not drifted.

8–Advanced destruction with loss of ma.sticatory

function. The tooth could have been loose, could

have drifted, or could sound dull on percussion

with a metallic instrument.

RULE: When in doubt, the lesser score was assigned.

Each tooth present in the mouth, unless it is a root,

was scored, and the arithmetic average of all scores

was the individual’s PI.

The Simplified Oral Hygiene Index (OHI-S)

Selected surfaces of six teeth were used in making

this estimation of oral hygiene status. For the

purposes of this examination each buccal or lingual

surface that was use d was considered to encompass

half of the circumference of the tooth. The buccal

surface of a molar, for example, was considered to

include half of the mesial surface and half of the

distal surface.

On both sides of the arch the posterior tooth

assessed was the most antenor, filly erupted permanent molar or, in its absence, the most distal fully

erupted primary molar. In most cases, this was a fmt

permanent molar; in other cases it was a fmt or

second primary molar or a second permanent molar.

The buccal surfaces of upper molars and the lingual

of lower molars were examined. In the anterior

portion of the mouth, the labial surfaces of the upper

right central incisor and the lower left central incisor

were examined. When these teeth were missing, only

the adjacent central incisor was examined.

Examining for oral debris. –The surface area

covered by debris was estimated by running a No. 5

explorer along the surface being examined and noting

the occlusal or incisal extent of the debris as it was

removed from the tooth surface and adhered to the

explorer.

Scores were assigned according to the foIlowing

criteria:

O–No debris or stain present.

l–(a) Soft debris covering not more than the gingival

third of the tooth surface, or

(b) the presence of extrinsic stains without debris

regardless of surface Mea covered.

2–Soft debris covering more than one-third but not

more than tw~thirds of the exposed tooth surface.

3–Soft debris covetig more than two-thirds of the

exposed tooth surface.

Examining for oral calculus. –A No. 5 explorer

was also used to estimate the surface area covered by

supragingival calculus and to probe for subgingival

calculus.

Scores were assigned according to the following

criteria:

O–No calculus present.

1–Supragingival calculus covering not more than

one-third of the exposed tooth surface.

2–Supragingival calculus covering more than onethird but not more than two-thirds of the exposed

tooth surface, and/or the presence of individual

flecks of subgingival calculus around the cervical

portion of the tooth.

3–Supragingival calculus covering more than twothirds of the exposed tooth surface and/or a

continuous heavy band of subgingival calculus

around the cervical portion of the tooth.

Edentulous arches-denture status

No entry was made in this section unless at least

one arch was edentulous. An arch with erupted or

partly erupted teeth was considered edentulous if a

fidl denture was being used.

Absent. –No teeth (or roots) were present in the

arch and the exarninee did not have a denture either

in his mouth or on his person at the time of

examination.

Present. –A denture was present in the mouth and

not defective at the time of examination.

Defective. –There is visible evidence that the

denture was causing extensive destruction of the

primmy stress-bearing areas of the ridge or palate.

53
Tissue in these areas may have been acutely inflamed;

bone resorption may have occurred; hypertrophied

tissue may have been present. The denture was also

defective if it was in the possession of the examinee

at the time of the examination but not in the mouth.

If a denture status code for either or both arches was

marked, the following should also be true:

A.

B.

c.

The spaces for the appropriate arch (or arches)

under Status of Tooth Spaces, Periodontal Index,

and Makdigned Teeth should be left blank.

‘The “NAY’spaces for the appropriate arch (or

arches) under OHI should be marked.

The “NAY’spaces under Opacities, Buccal Segment Relatio~, Posterior C~oss-bite, Incisor Relationship, and Handicapping Labio-Lingual

Deviations (HLD) index should be marked.

Treatment needs

This estimate was based on the examiner’s clirdcal

judgment. Certain factors, however, would have been

kept in mind when it was decided whether missing

teeth ought to be replaced and when all remaining

teeth in an arch ought to be extracted and a full

denture constructed. In addition to the status of oral

hygiene and periodontal disease, the examinee’s age,

his responses to the questions about chewing and

eating, and the probable benefit of recommended

service to the individual’s health and nutrition were

all taken into account.

“Yes” or “no” was reported for each area of

need. Counts of the numbers of ffings and extractions needed were recorded when appropriate, and

teeth to be replaced by freed bridges or partial

dentures were indicated. The type of denture was

marked in the area provided for repair, reline, and

construction of dentures.

The examiners

Each of the 20,218 sample persons who received

dental examinations during 1971-74 (and for whom

the dental records were available) was examined by

one of the 10 dentists. The dentists included two

senior examiners ( 1 and 2) who trained and supervised the other dentists (3-1O).

S)ample persons were not assigned randomly or

equally among the various examiners. At most survey

locations they were examined by only one dentist (3,

4, 5, 6, 7, 8, 9 or 10). At 18 of the 65 locations,

however, a small subsample was examined by either

senior, dentist or, as occurred at four locations, by

both senior dentists. Thus, the senior dentists examined relatively few sample persons. All dental records

that were done at survey location 54 were lost and

data for them had to be imputed. The examiner

number is unknown for these records. The number

and percent of persons examined by each dentist

(with records available) are shown in table V.

Most examinations completed by the senior de,ntists resulted from a planned series of replicate

examinations. As a rule, the findings of the senior

dentist were made part of the sample person’s

exainination record, and the findings of the dentist

with whom he was paired were kept separate. The

primary aim of the replicate examinations was 10

correct any examiner divergence from the accepted

examination procedures.

Throughout the replicate examinations, the senior

dentist completed his examination first and dictated

his findings to a trained recorder. After completing

the examination, the senior dentist also recorded th[e

findings of the other dentist, who had previously

been absent from the examining room. Appreciable

interexarniner differences as well as any procedure

that diverged from the accepted one were discussed

and, if indicated, either were resolved or corrected

while the sample person was still present. However,

the findings originally recorded were not altered.

To indicate the level of agreement among examiners, the results of the replicate examinations are

shown in table VI. The direction of the disagreements

that occurred is shown by a plus or minus sign. A pluE

sign indicates that a finding of the senior dentist wals

lower than that of another dentist, and a minus sign 

indicates the opposite,

Perfect agreement between senior dentists and the

other examining dentist ranged from a low of about

56 percent on untreated decayed teeth to a high af 

69 percent on fdled teeth. Perfect agreement on DMIF

teeth occurred in about 44 percent of the examinations, whereas disagreement on more than one DMI?

tooth occurred in over one-third of them.

The results of the replicate examinations indicate

that the level of examiner agreement was not as high

during the NHANES as it was during the earlier

survey of children and youths. 3Y4 The lower level alf
