ABSTRACT
Aim:
To describe the prevalence of dental caries and fluorosis in schoolchildren from two differenttowns in São Paulo State, Brazil, 2007 - town A (water fluoridation since 1971) and town B (waterfluoridation since 1997) - and to compare current prevalence rates with previous surveys, intown A, for dental caries (1971-2005) and for dental fluorosis (1991-2001), and in town B, fordental caries and dental fluorosis (1991-2004).Methods:
The sample consisted of 724schoolchildren aged 12 years from public and private schools (town A) and 197 schoolchildrenfrom public schools (town B). The schoolchildren were examined under natural light by a dentist,using CPI probes and oral mirrors. The mean number of decayed, missing and filled permanentteeth (DMFT), and Significant Caries (SiC) Index were determined for dental caries and theThylstrup and Fejerskov index (T-F) for fluorosis.Results:
The DMFT was 0.85 and 1.02; SiCindex was 2.52 and 2.83 in towns A and B, respectively. Fluorosis prevalence was 29.4% (townA) and 25.4% (town B). In both towns, a significant dental caries reduction has been observed.Concerning fluorosis prevalence, an increase of 44.1% was noted in town A and 1170% in townB.Conclusions:
Results show continuous decrease in dental caries experience in both towns.Regarding fluorosis prevalence, stabilization trends were observed in town A. In town B, however,a constant increase was noted.
