[Prevalence of cavities among adolescents in public and private schools in João Pessoa, Paraíba State, Brazil].
The purpose of this study was to ascertain the prevalence of cavities among adolescents in public and private schools in João Pessoa, Paraíba State, Brazil, comparing the DMFT in terms of gender and age, as well as education levels and quality among mothers in these two types of schools. The sample consisted of 3,330 adolescents between twelve and fifteen years old: 1,665 attending public schools and 1,665 attending private schools. The DMFT was evaluated by the WHO criteria (1997), using the Kappa (0.92) intra-examiner agreement for cavity diagnoses and the Mann-Whitney and Kruskal-Wallis statistical analyses. The prevalence of cavities in public schools was 51.6%, compared to 9.3% in private schools. The DMFT for girls was 4.79 and 3.46 for boys in public schools (p<0.0001) and 2.11 and 1.65 (p=0.0007) in private schools. At the age of 12 years, the DMFT was 3.37 in public schools and 1.35 in private schools, while for the age of 15 it was 5.65 and 2.88 for each type of school. Among children whose mothers graduated from high school, the average DMFT was 4.21 in public schools and 1.81 in private schools. The prevalence of cavities was higher among girls in public schools, increasing with age and decreasing with higher education levels among mothers.
