Studies investigating restorations placed in the primary dentition showed no significant differences between the groups after 12 and 24 months .
In the permanent dentition , the longevity of ART restorations is equal to or greater than that of equivalent amalgam restorations for up to 6.3 years and is site-dependent .
No difference was observed in primary teeth .
The aim was to report on the longevity of  restorations placed using the atraumatic restorative treatment ( ART ) approach  compared with that of  equivalent placed amalgam restorations .
Access to dental care for children in the United States: a survey of general practitioners.
BACKGROUND In response to concern that inadequate dental school training may create a barrier to access to care for children , the authors conducted a survey concerning general practitioners ' practice patterns involving child patients . METHODS The authors requested a list of 4,970 r and omly chosen general practitioners from the American Dental Association Survey Center . They then sent those dentists a written survey asking whether and in what numbers they treat children ; the ages and caries levels of any children they do treat ; their perceptions of their educational experiences in pediatric dentistry , and their perceived needs for continuing education in pediatric dentistry . They analyzed data using chi2 . RESULTS Ninety-one percent of the general dentists surveyed treated children , but those younger than 4 years of age , with high levels of caries , and whose care is funded by Medicaid were represented in very low numbers . The types of patients treated and procedures performed by the respondents were significantly ( P < or = .05 ) associated with the intensity of the respondents ' educational experiences , except for the number and types of Medicaid patients they treated . CONCLUSIONS These data indicate that the vast majority of general practitioners treat children in their practice s , but there still are groups of children for whom access to dental care is a problem . PRACTICE IMPLICATION S Very young children , children with high levels of caries and Medicaid-covered children have difficulty finding dental care in the general practice community
