|Abstract:||Investigating dental caries and fluorosis prevalence over time is an important measure for monitoring trends in oral health. This work aimed to describe the prevalence of dental caries and dental fluorosis of 11- to 12-year-old schoolchildren from Iracemapolis, Brazil, in 2004 (n=236) and to compare the current prevalence rates with those from previous surveys carried out in 1991 (n=200), 1995 (n=160), 1997 (n=314) and 2001 (n=244). The schoolchildren of both genders from all public schools were examined by two calibrated dentists (Kappa > 0.81), using dental probes and buccal mirrors under natural light in an outdoor setting. Dental caries and fluorosis were measured using the DMFT and Thylstrup-Fejerskov (T-F) indexes, respectively. The variation of DMFT index over time was assessed by analysis of regression and the fluorosis prevalence (T-F>1) was compared over time by the Chi-square test at 5% significance level. In 2004, the mean value for DMFT was 1.2; 50% of the children were caries-free, and 15.7% presented dental fluorosis (T-F>1). A significant caries reduction (82.1%) and a significant increase (685%) of fluorosis prevalence have been observed from 1991 to 2004 (p < 0.01). The results suggest a continuous decrease of dental caries experience and an increase of dental fluorosis prevalence in 11-to 12-year-old schoolchildren from this Brazilian town as well as indicate that further epidemiological surveys should be carried out in order to monitor these trends.|
