GUSHI, Lívia Litsue et al. Dental caries in 15-to-19-year-old adolescents in São Paulo State, Brazil, 2002. Cad. Saúde Pública [online]. 2005, vol.21, n.5, pp. 1383-1391. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X2005000500010.

Dental caries was evaluated by surveying 15-to-19-year-olds in the State of São Paulo, Brazil, in 2002, concerning disease prevalence and severity according to age, gender, ethnicity, and public water supply fluoridation. This cross-sectional study was based on data collected through an oral dental health epidemiological survey. Adolescents (n = 1,825) were examined at their homes by 132 dentists from 35 cities in the State of São Paulo. Chi-square, Kruskal-Wallis, and Mann-Whitney tests were used (a = 5%). The SiC Index was used to determine the groups having higher caries experience. DMF-T was 6.44 (sd = 4.60) and SiC Index was 11.68. Caries-free frequency was 9.6%. No statistically significant difference was observed for DMF-T in relation to public water supply fluoridation; however, there was a high percentage of caries-free individuals in cities with fluoridation. Caries conditions were worse in males. A higher prevalence of decayed and missing teeth was observed in the non-white groups. Therefore, emphasis is recommended on strategies to mitigate harm by caries progression, especially in higher-risk groups.
