Survival of atraumatic restorative treatment (ART) sealants and restorations: a meta-analysis
The purpose of this study is to perform a systematic investigation plus meta-analysis into survival of atraumatic restorative treatment (ART) sealants and restorations using high-viscosity glass ionomers and to compare the results with those from the 2005 ART meta-analysis. Until February 2010, four databases were searched. Two hundred four publications were found, and 66 reported on ART restorations or sealant survival. Based on five exclusion criteria, two independent reviewers selected the 29 publications that accounted for the meta-analysis. Confidence intervals (CI) and or standard errors were calculated and the heterogeneity variance of the survival rates was estimated. Location (school/clinic) was an independent variable. The survival rates of single-surface and multiple-surface ART restorations in primary teeth over the first 2 years were 93% (CI, 91–94%) and 62% (CI, 51–73%), respectively; for single-surface ART restorations in permanent teeth over the first 3 and 5 years it was 85% (CI, 77–91%) and 80% (CI, 76–83%), respectively and for multiple-surface ART restorations in permanent teeth over 1 year it was 86% (CI, 59–98%). The mean annual dentine lesion incidence rate, in pits and fissures previously sealed using ART, over the first 3 years was 1%. No location effect and no differences between the 2005 and 2010 survival rates of ART restorations and sealants were observed. The short-term survival rates of single-surface ART restorations in primary and permanent teeth, and the caries-preventive effect of ART sealants were high. Clinical relevance: ART can safely be used in single-surface cavities in both primary and permanent teeth. ART sealants have a high caries preventive effect

Prevalência de fluorose dentária em escolares de 12 anos de idade, Ouro Preto/MG - 2003 Prevalence of dental fluorosis in 12 year-old schoolchildren, Ouro Preto/MG - 2003
OBJETIVO: verificar a prevalência da fluorose dentária em escolares de 12 anos de idade em Ouro Preto. METODOLOGIA: estudo seccional incluindo 248 crianças selecionadas aleatoriamente em 11 escolas do municÃpio. A amostra foi calculada de acordo com a metodologia descrita no Projeto SB2000. Os exames foram realizados por cirurgião-dentista treinado e calibrado. Os Ãndices utilizados para medir a fluorose foram: Ãndice de Dean e Ãndice comunitário de fluorose. RESULTADOS: De 248 crianças selecionadas, 159 (64,1%) participaram deste estudo. A prevalência de fluorose (Ãndice de Dean) encontrada foi de 11,4%, sendo composta pela condição muito leve (10,1%) e leve (1,3%). A condição moderada e severa de fluorose não foi encontrada. Os dentes mais acometidos por fluorose foram os pré-molares, molares, incisivos e caninos. Não houve diferença entre os sexos quanto ao grau de fluorose, e o Ãndice comunitário de fluorose foi de 0,29. CONCLUSÃO: a fluorose em crianças de 12 anos não é um problema de saúde pública em Ouro Preto, dado que a prevalência não é alta e quase todos os casos encontrados são muito leves.<br>OBJECTIVE: to find out the prevalence of dental fluorosis in 12-year-old schoolchildren in Ouro Preto. METHODOLOGY: cross-sectional study including 248 children randomly selected from 11 schools in the town. The sample was calculated according to the methodology described in Project SB2000. Exams were undertaken by a trained and calibrated dentist. Dental fluorosis was evaluated by the Dean index and index of community fluorosis. RESULTS: 159 (64.1%) children, among the 248 who were selected, participated in the study. The prevalence of fluorosis (Dean index) found was 11.4%, and it was found to be a very mild (10.1%) or mild (1.3%) condition. Moderate and severe fluorosis were not found. The teeth most affected by fluorosis were pre-molars, molars, incisors and canines. There was no difference between genders as to the degree of fluorosis, and the index of community fluorosis was 0.29. CONCLUSION: fluorosis in 12 year-old children is not a public dental health problem in Ouro Preto, as the prevalence is not high and nearly all cases are very mild
