Foi desenvolvido um estudo transversal na cidade de Diamantina, Minas Gerais, com crian?as selecionadas aleatoriamente em escolas p?blicas da cidade. A coleta de dados foi realizada atrav?s da aplica??o de question?rios aos pais/respons?veis que responderam ?s quest?es sobre aspectos socioecon?micos e comportamentais da crian?a. O exame cl?nico odontol?gico dos escolares foi realizado na escola, com aux?lio uma lanterna de cabe?a pelas examinadoras treinadas e calibradas, ap?s a escova??o dent?ria e sob isolamento relativo. Foram realizados os seguintes exames cl?nicos: a avalia??o da qualidade cl?nica das restaura??es conforme crit?rios do ?United States Public Health Service? (USPHS) modificados; a avalia??o da presen?a de c?rie moderada/extensa atrav?s dos crit?rios do ?International Caries Detection and Assessment System? (ICDAS II); a avalia??o do risco de c?rie atrav?s dos crit?rios da ?American Dental Association? (ADA) e a avalia??o dos ?ndices de placa vis?vel e sangramento gengival (AINAMO & BAY). Foi realizada a an?lise descritiva dos dados e a an?lise estat?stica incluiu a distribui??o de frequ?ncia das vari?veis e regress?o log?stica multin?vel. O desfecho foi a qualidade insatisfat?ria das restaura??es odontol?gicas em dentes posteriores dec?duos. As vari?veis independentes inclu?ram fatores individuais e relacionados aos dentes restaurados. Foram avaliados 400 escolares, 98 crian?as tinham dentes restaurados e 217 restaura??es foram avaliadas. A preval?ncia de restaura??es insatisfat?rias foi de 34,6%. Os escolares com restaura??es em am?lgama apresentaram menos chance de ter restaura??es insatisfat?rias, comparadas ?s restaura??es em ion?mero de vidro (OR=0,11; IC 95% 0,02-0,49). As chances de apresentarem restaura??es odontol?gicas insatisfat?rias foram maiores em crian?as cavitada, moderada/extensa (OR= 6,79 IC 95% 2,20-20,93) e ?ndice de placa vis?vel ? 20% (OR=2,28 IC 95% 1,05-4,92). ? importante que se conhe?a esses fatores para que sejam trabalhados e minimizados na pr?tica cl?nica, otimizando assim, a sobrevida das restaura??es odontol?gicas. Sendo relevante, o monitoramento das restaura??es para detec??o de falhas e realiza??o do reparo ou substitui??o, quando necess?rio.Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES)Disserta??o (Mestrado) ?

A cross-sectional study was developed in the city of Diamantina, Minas Gerais, with children randomly selected from public schools in the city. Data collection was carried out through the application of questionnaires to parents / guardians who answered questions about the child's socioeconomic and behavioral aspects. The students' dental clinical examination was performed at school, with the help of a headlamp by trained and calibrated examiners, after tooth brushing and under relative isolation. The following clinical examination were performed: the evaluation of the clinical quality of the restorations according to the modified United States Public Health Service (USPHS) criteria; the assessment of the presence of moderate / extensive caries using the criteria of the ?International Caries Detection and Assessment System? (ICDAS II); the evaluation of the risk of caries using the criteria of the "American Dental Association" (ADA) and the evaluation of the indices of visible plaque and gingival bleeding (AINAMO & BAY). Descriptive analysis of the data was carried out and the statistical analysis included the frequency distribution of the variables and multilevel logistic regression. The outcome was the unsatisfactory quality of dental restorations on posterior deciduous teeth. The independent variables included individual factors and related to the restored teeth. 400 students were evaluated, 98 children had restored teeth and 217 restorations were evaluated. The prevalence of unsatisfactory restorations was 34.6%. Schoolchildren with amalgam restorations were less likely to have unsatisfactory restorations compared to glass ionomer restorations (OR = 0.11; 95% CI 0.02-0.49). The chances of presenting unsatisfactory dental restorations were higher in children with cavitation, moderate / extensive (OR = 6.79 95% CI 2.20-20.93) and visible plaque index ? 20% (OR = 2.28 CI 95% 1.05-4.92). It is important to know these factors so that they are worked on and minimized in clinical practice, thus optimizing the survival of dental restorations. Relevant, monitoring restorations to detect failures and carry out repair or replacement, when necessary
