Abstract

Objective: To compare the national epidemiological surveys on oral health (SB Brasil) of 2003 and 2010, regarding the factors associated with water fluoridation and dental caries at 12 years of age, highlighting possible inequities.

Material and methods: Data from 57,388 inhabitants from the 50 coinciding municipalities were used in both surveys. With data from SB Brasil 2003, the cut-off point for the presence of fluoridation was 1990 and the independent variables were from 2000; for SB Brasil 2010, this cut-off was 2004 and the independent variables were from 2010. There were explanatory variables: macro-region, population size, Municipal Human Development Index (HDI-M) and access to piped water. The Chi-Square test (p <0.05) was applied to identify associations between explanatory variables and the outcomes of interest.

Results: Less favored macro-regions, with fewer inhabitants, lower HDI-M and less access to piped water, were those that received less fluoridated water or received it, this happened later, also with an impact on the increase in the experience of dental caries.

Conclusion: There was no improvement in the period in terms of reducing inequities and the relationship between fluoridation and dental caries.
