Prevalence of recurrent headache and mandibular dysfunction in patients with unsatisfactory complete dentures
Authors: Magnusson Tomas 
Published: May 2006

AbstractThe prevalence of headache and mandibular dysfunction was studied in 43 patients with unsatisfactory complete dentures waiting for prosthodontic treatment at the Dental Clinic of the National Dental Service in Jokkmokk, Sweden. In addition to answering a questionnaire, all patients underwent a clinical‐functional examination of the masticatory system. Seventeen patients (40%), 15 women and two men, reported recurrent headache. 63% of the men and 83% of the women showed marked clinical signs of mandibular dysfunction. A significant correlation between headache and mandibular dysfunction was found. The low representation of complete denture wearers in clinical series of patients referred for treatment of mandibular dysfunction may be due to a reduced propensity to seek help and a greater willingness to accept a certain degree of dysfunction compared with other people.
Relationship of children's anxiety to their potential dental health behaviour
Authors: Wright F. A. C. 
Published: May 2006

AbstractIn this study of 200 New Zealand schoolchildren aged 7‐13 years, a questionnaire interview was used to gain information related to estimating dental anxiety and general illness anxiety. Information related to sociodemographic differences, belief differences, and an estimate of potential health behaviour was also collected. Oral examinations were performed and the number of dental restorations present recorded. Dental anxiety was associated with memory of pain during a dental visit. The number of restorations present, and a history of pain during a dental visit, were important predictors of illness anxiety. Neither dental anxiety nor illness anxiety operating alone provided an estimate of future dental health behaviour. Dental anxiety and illness anxiety operated through a complex interplay of variables. A stepwise multiple regression technique was used to determine the possible pathways to potential dental health behaviour. Perceived vulnerability to dental caries and perceived severity of dental disease were important in the prediction of potential denture wearing; school attended and ethnic background were useful predictors of potential extraction seeking; and school grade and level of perceived internal control were predictors of potential preventive visitation.

Authors: Järvinen Seppo , Lehtinen Liisa , Milen Anneli 
Published: May 2006

AbstractThe frequency of geminated and fused primary teeth was studied in a sample of 1141 Finnish children aged 3‐4 years. The prevalence was 0.7%. All the joined teeth were found in the anterior area of the mouth. In seven cases the diagnosis was a fusion of two separate teeth, and in one case it was a gemination of a single tooth. A correlation between joined teeth in primary dentition and numerical variations of teeth in permanent dentition was noted in three cases.
Patterns of tooth vulnerability to caries in South African high school pupils
Authors: Cleaton‐Jones P. , Walker A. R. P. 
Published: May 2006

AbstractCaries prevalence and distributions were studied in 761 South African high school pupils aged 17 years in four ethnic groups, living in urban (low F) and rural (low and high F) areas. Mean DMFT values were significantly higher among White pupils than all other groups. Comparison of mean DMFT among the Black pupils showed that urban Black dwellers had a significantly higher score than rural pupils when caries‐free individuals were included in the analysis, but not when scores for only those with a DMFT of 1 or more were compared. No significant differences were found between the DMFT values of Black rural pupils living in high or low fluoride areas. Among Black rural pupils, dental caries was approximately three times more common in permanent second molars compared with permanent first molars. In urbanized Black, Coloured, Indian and White subjects, the molars were approximately equally affected.
Dental caries prevalence and treatment status of 12‐year‐old children in a non‐fluoridated area
Authors: Kinirons Martin J. , Mageean James F. 
Published: May 2006

Abstract424 12‐year‐old children were examined in Mallow, a non‐fluoridated town in North Cork, to ascertain the dental status of children finishing first level education. Both the caries prevalence and the treatment pattern were examined. The DMF was found to be 6.58 and the RI was 52.5%. A new index of restored and sound teeth (RSI) was applied and a value of 38.6% was obtained.
Impact of a periodontal course on oral hygiene and gingival health among senior dental students
Authors: Tenenbaum H. 
Published: May 2006

AbstractThis survey attempted to determine the impact of the periodontal course on oral hygiene and gingival health among 50 senior dental students. The course included the following: patient motivation, instruction in oval hygiene procedures and plaque control, scaling and curellage, temporary splinting and occlusal adjustment. Without advance notice, plaque deposits were scored using the Plaque Index and gingival health was determined using the Gingival Index. The results were collected at the beginning and at the end of the periodontal course (about 2 months). The results were analyzed using the paired t‐test. No improvement of either oral hygiene or gingival health was noted at the end of the periodontal course. It seems that even some dental students, who should know the direct relationship between bacterial plaque and periodontal diseases and should be better motivated than the average patient, failed to demonstrate effective oral hygiene. It is difficult to expect an improvement of patient oral hygiene, when the patients have been motivated by students who are unable to perform satisfactory personal oral hygiene themselves. It is suggested that a greater emphasis be placed on patient motivation and instruction in oral hygiene throughout the dental curriculum.
Age, degree of mental retardation, institutionalization, and socioeconomic status as determinants in the oral hygiene status of mentally retarded individuals
Authors: Tesini David A. 
Published: May 2006

AbstractOral hygiene has been implicated as a causal factor in the development of dental caries and periodontal disease in mentally retarded individuals. Little attention, however, has been given to the determinants of oral hygiene status. The present paper assesses the oral hygiene status of institutionalized (I) and noninstitutionalized (NI) mentally retarded (MR) individuals aged 4 through 25, in relation to age, degree of mental retardation, and socioeconomic status. Institutional status was found to be a major determinant in oral hygiene conditions of the study group, as IMR individuals had significantly higher OHI scores than NIMR individuals. Associations of age and OHI were significant only for NIMR. Although differences between land NI groups, with respect to degree of mental retardation, were seen for mildly, moderately, and severely retarded, no significant difference in OHI scores between I and NI profoundly retarded was seen. Socioeconomic status was not found to be a significant factor in the oral hygiene status of MR individuals. This study emphasizes the need to assess age, degree of mental retardation, and institutional status when implicating oral hygiene in caries and periodontal disease prevalence in MR individuals.

Published: May 2006

AbstractOral health parameters were examined for 211 schoolchildren (128 Aborigines and 83 Caucasians) representative of the 6–8 and 10–11 year age groups in the Brewarrina and Walgett areas of western New South Wales (fluoride in water ≤ 0.02–0.26 parts/106). Despite similar dietary carbohydrate challenge and tooth eruption patterns, Aboriginal children, most of whom were members of a transitional community within a low socioeconomic stratum, had higher prevalence of caries (DIMFT) and severity rating of carious lesions (SR), poorer oral hygiene (OHI) and more gingivitis (PI) than Caucasian children, in both age groups. Tooth defects were more frequent (2.5 times) and severe in Aborigines than in Caucasians. Outstanding treatment needs were very high in both ethnic groups, but more so in Aborigines.

Published: May 2006

AbstractA pilot survey of oral health included 83 adolescent and adult Aborigines (41 M, 42 F, range 16–70 years, mean age 37.3 years), resident in fringe settlements around the far western New South Wales towns of Brewarrina and Walgett (fluoride in water ≤ 0.02‐0.26 parts/106). Dental caries prevalence (mean DIMFT per person) increased from 17.1 at 20 years to 20.7 at 35 years and declined to 14.6 by the age of 50 years and over. Oral hygiene (OHI) was poor overall and deteriorated with age. Periodontal status (PI) was significantly correlated with the presence of debris (DI) and calculus (CI). The mean PI increased from 1.7 at 20 years to 4.8 at 43 years and over. Tooth mortality reached 75% by the age of 43 years. Prosthetic needs were correspondingly high, but 95% of denture requirements were unmet. No evidence of effective or sustained oral health care was seen; 38% of subjects needed emergency treatment.
Panoramic radiographic examination of 704 Danish children aged 9–10 years
Authors: Locht Sven 
Published: May 2006

AbstractPanoramic radiographs of 704 apparently healthy children aged 9–10 years were examined regarding anomalies and pathologic conditions in the maxillofacial area. Almost all findings were mesial to the molars. 1.7% of the children had a supernumerary tooth, 7.7% had hypodontia. Malposition of 631 permanent teeth was recorded. 42 dentigerous cysts were detected. Malformed crown or root was seen on 60 permanent teeth. Caries was found on 224 primary and 32 permanent teeth. 257 primary teeth showed atypical resorption, and 53 had a periapical inflammatory radiolucency. 20 retained roots of primary teeth were detected. 31 maxillary sinuses had an opacity. There were very few other findings.
Prevalence of narrow zone of attached gingiva and improper attachment of labial frena in youths
Authors: Jańczuk Zbigniew , Banach Jadwiga 
Published: May 2006

AbstractAn epidemiologic study comprising 1542 girls and boys aged 15–17 revealed that the occurrence of the narrowest attached gingiva zone (> 0, ≤ 1 mm) was more frequent in the mandible (23.0%) than in the maxilla (2.0%). At the same time, the first type of labial frena attachment (mucosal type) was observed most often, again dominating in the mandible (71.0%).
Toothbrushing in relation to other health habits in Finland
Authors: Rajala M. , Honkala E. , Rimpelä M. , Lammi S. 
Published: May 2006

AbstractThe dimensionality of health behavior is disputable. In the present study an effort was made to shed more light on this problem. Interview data were obtained from 3209 13‐19‐year‐old Finnish adolescents concerning the subjects' smoking habits, use of alcohol, physical activity, toothbrushing and dietary habits. A clear positive relationship was observed between tooth‐brushing and the use of sugar‐containing snacks. Use of alcohol seemed to have slight adverse effect on toothbrushing. Smoking was also weakly related with sporadic toothbrushing. Sports‐oriented girls seemed to be regular toothbrushers. It was concluded that the possible comprehensive nature of health behavior should be more appreciated.

Published: May 2006

AbstractA longitudinal study on the effect of a preventive program based on bimonthly professional toothcleaning and hygiene instruction was carried out on 293 schoolchildren from the 1st, 4th and 7th grades. The prophylactic paste used contained 0.8%sodium monofluorophosphate. The control groups brushed with a 0.2% sodium fluoride solution four to five times during each school year. After 2 years the Visible Plaque Index and the Gingival Bleeding Index were significantly reduced for all grades in the test groups as compared to the controls. The percentage of children without new caries lesions increased significantly from an average of 50 % in the control to 71% in (he lest group. The mean caries increments during the 2 years, excluding occlusal surfaces, were 0.22, 0.28 and 1.20 in the three test groups. This represents an average caries reduction of 65%, compared to the control group. The increment reductions reached borderline significance, using the chi‐square test.
Test of a method to determine socially acceptable occlusal conditions

Published: May 2006

AbstractA method for determining the social acceptability for dental appearance across the full range of occlusal conditions found in a natural population was developed and tested. The strategy used in developing the Social Acceptability Scale of Occlusal Conditions (SASOC) was to present photographs of 100 dental study models to a large sample of high school students (n= 880) and their parents (n= 403) whose responses were measured by asemantic differential instrument. After refinement of the semantic differential instrument scale scores were derived for each study model by computing the mean individual scores. Ranks were assigned to the mean scores. The Pearsonian correlation obtained between parent and student subsamples was 0.95. The reliability and validity of SASOC were assessed. COCSTOC measures of specific occlusal traits for these 100 study models are available. The future task involves the development of a highly reliable regression equation for predicting social acceptability scores from a small number of objective physical measurements.

Published: May 2006

AbstractThe Myofascial Pain Dysfunction Syndrome (MPD) was investigated in 94 twin pairs (21 male pairs and 73 female pairs), who had not been selected with respect Lo MPD. The frequency of past and/or present symptoms was found to be 10% in males and 27 % in females. No differences between monozygous (identical) and dizygous (non‐identical) female twins was found in pair‐wise concordance rates, the concordance rate being higher than expected to occur by chance in both twin types. The findings are compatible with the view that environmental influences give rise to this specific stress‐reaction pattern.

AbstractThe purpose of this study was to evaluate oral health information delivered by the Spanish mass media. The study was composed of two parts. In a quantitative study three media were selected: Press. radio, and television. The study was carried out between December 1987 and March 1988. and the media with largest numbers and audience were selected. Information variables were: politics economy‐labor culture‐education interviews events‐reports sports leisure publicity health oral health miscellaneous. The mass media studied dedicated a very small percentage of their space/time to health information, with a clear predominance of oilier themes such as publicity, politics, and sports (17/1). In relation to oral health, results were even more significant because the space time dedicated to health in relation to oral health was 180/1 (P < 0.01). Most of (he oral health lime was given via promotional or politico‐professional issues (P < 0.05). In a qualitative study all available information relating in any way with oral health was selected from a survey of all written news by the non‐specialized Spanish press that appeared during 1 yr (Jan 1987 Jan 1988). Reports dedicated to education were only 170(31.48%) of the total (540) oral health reports. From 170 reports dedicated to oral health. 33 (19.41%) presented some sort of error and 137 (80.59) had an adequate educative content. Caries was the topic more frequently covered. 77.06% of the data, in contrast to periodontal disease, dealt with by only 33.53%. The qualitative level of data using a Score Level Index (SLI) was 42.73% of the highest possible level. Implications for public health dentistry are discussed.
Approximal caries and frequency of bitewing examinations in Swedish children and adolescents

Published: May 2006

AbstractThe aim of this study was to assess the number of, and time intervals between, bitewing examinations performed on a group of Swedish patients between 3 up to and including 18 yr of age and to relate them to the accumulated posterior approximal caries experience of the patients as found in the last bitewing examination before age 19. The patients showed a marked variability in approximal caries experience. 25% accounted for about 1% of the total number of carious lesions and restorations accumulated up to age 19 while 25% accounted for 60%. From age 9 up to age 18 more than 75% of the patients were subjected to at least one bitewing examination annually. Between 10 and 15 yr of age more than 90% received annual radiographic examinations. Mean number of bitewing examinations was 10.4 and the average lime interval between bitewing examinations was 1 1.5 months. 11% of the variation in the number of bitewing examinations and 11% of the variation in average time intervals between bitewing examinations could be explained by the number of lesions and restorations in the approximal surfaces of the patients accumulated up to age 19.
Predicting development of approximal dentin lesions by means of past caries experience
Authors: Lith Agneta , Gröndahl Hans‐Göran 
Published: May 2006

AbstractThe aim of this study was to assess the accuracy in predicting future development of approximal dentin lesions using radiographically observed numbers of restored and carious surfaces at age 13 as diagnostic criteria. ROC curve technique was applied employing the development of at least one new dentin lesion from age 1 3 to age 15 and 18 respectively, as validating criterion. Two groups of patients were considered, residing in communities with water fluoride content of 0.2 ppm and 1.2 ppm. respectively. Results showed that the development of dentin lesions could be predicted with an accuracy similar to that of many other dental radiographic procedures. This implies that it ought to be possible to use previous caries experience as a means of individualizing the scheduling of future radiographic procedures.
Caries prevalence in primary teeth as a predictor of early fissure caries in permanent first molars
Authors: Raadal Magne , Espelid Ivar 
Published: May 2006

AbstractThe study aimed to examine the validity of employing the caries experience of the primary dentition for predicting early caries in the permanent first molar fissures. Subjects consisted of 192 children who were followed for 2 yr, 91 of whom were pursued for a further year, all receiving semiannual check‐ups. The caries prevalence in the primary dentition (dmft). excluding incisors, was recorded at baseline, which was the year the children became 6. Fissure caries in the permanent first molars was recorded as being confined to enamel or dentin, based on findings during cavity preparation. The correlation between dmft and the number of intact permanent first molars was –0.368 and –0.337 after 2 and 3 yr observation respectively. When the children were grouped according to their dmft, a statistically significant relationship was found between the dmft and the number of intact molars in each individual. The positive and negative predictive values as well as the sensitivity and specificity of different dmft values were calculated, and the relationship between them illustrated by the use of ROC curves. Even if there are no specific dmft values which seem obviously favorable for the purpose, these data give information relevant in planning for large scale use of fissure sealing in preventing early fissure caries in permanent first molars.
Efficacy of APF treatments without prior tooth cleaning targeted to high‐risk children
Authors: Olivier Marie , Brodeur Jean‐Marc , Simard Paul L. 
Published: May 2006

AbstractA clinical field trial was conducted, over a 2‐yr period, to evaluate the efficacy of bi‐annual APF gel topical applications without previous prophylaxis in reducing dental caries among high‐risk children living in non‐fluoridated communities. 488 children 6 yr old. presenting at least three cavities on proximal surfaces of their primary teeth, were randomly assigned to two groups. The experimental group received bi‐annual topical APF gel applications and the control group received a placebo. All treatments were given at school without any prior tooth cleaning. The APF gel provided a 34.3% reduction in caries incidence (P‐value = 0.03) among the children with 3–14 cavities on their primary teeth at the beginning of the study. However, the treatment did not show any efficacy in reducing caries incidence among the higher‐risk children having initially more than 14 cavities. These findings suggest that the efficacy of APF gel applications without previous prophylaxis varies according to the individual risk of the subjects and that more comprehensive programs should be targeted to very high‐risk children.
Discrepancy between need for prosthodontic treatment and complaints in an elderly edentulous population
Authors: Mojon Philippe , MacEntee Michael I. 
Published: May 2006

AbstractMost reports indicate that about two‐thirds of the elderly population have poor oral health but that only about one‐third complain of a problem. The reason for this discrepancy has never been explained adequately. The objective of this study was to estimate the need for prosthodontic treatment in an edentulous elderly population, and to identify factors associated with complaints, needs for treatment, and the use of dentures. Interviews and examinations were conducted to determine the oral health and dental concerns among 269 residents of longterm cure facilities in Vancouver. The need for prosthodontic treatment was considered under theoretical, clinical, and practical conditions, and related to various factors that might help to predict this need. During the interview, about half (54%) of the sample identified a problem, and X3% of the subjects were either using a denture with a major fault or were missing a denture. Seventeen percent of the sample would not benefit from treatment because of a severely resorbed residual ridge, while the presence of a complaint combined with a prosthodontic need indicated that about one‐third (36%) would seek and benefit from treatment. The proportion of subjects with complaints was larger among the more educated subjects, and among those who had been recently to a dentist. It was not possible to predict the need for treatment from any of the socioeconomic factors considered. No significant association was observed between the need for treatment and the complaints, and many subjects seemed to be resigned to their discomfort or had unrealistic expectations from their dentures.
