Dental pain, socioeconomic status, and dental caries in young male adults from southern Brazil.

The aim of this study was to assess dental pain prevalence and its association with dental caries and socioeconomic status in 18-year-old males from Florianópolis, Santa Catarina, Brazil. A cross-sectional study was conducted in a random sample (n = 414) selected from the Brazilian Army conscription list in 2003. Dental pain during the 12 months prior to the interview was recorded as the outcome. Socioeconomic data were obtained through a questionnaire. Dental caries experience was registered according to the DMFT Index. Analyses included simple and multiple non-conditional logistic regression following a hierarchical approach. Response rate was 95.6%. High rates of inter-examiner agreement were achieved (kappa > 0.83). Dental pain prevalence was 21.2% (95%CI: 17.3-25.1). After adjustment, individuals with one or more untreated caries were 3.2 times more likely (95%CI: 1.7-5.8) to have dental pain compared to caries-free subjects. Conscripts with low family income were 1.8 times more likely (95%CI: 1.0-3.3) to have dental pain than those with higher income.
