Varia？？es no nível de cárie dentária entre crian？as de 5 e 12 anos em Minas Gerais, Brasil

the aim of this ecological study was to analyze to what extent world health organization goals were met in relation to dental caries in 2000 in minas gerais state, brazil, identifying factors associated with variation in dmft and the occurrence of dmft < 3 among 12-year-old children and in the percentage of caries-free 5-year-olds. secondary data from different sources were used. linear regression and multiple logistic regression techniques were applied to the analysis of the numerical and dichotomous dependent variables. socioeconomic and dental services supply/utilization indicators were used as potential explanatory variables. the goals expressed by dmft < 3 at 12 years and a minimum of 50% caries-free 5-year-olds were met by 37% and 9% of the state's municipalities, respectively. in general the dependent variables were associated with socioeconomic level, and no associations were identified with dental care. the results should not be generalized, but they do suggest inequities in oral health and the role played by socioeconomic factors and water fluoridation.
