An epidemiologic study was conducted to evaluate the prevalence of dental fluorosis in Brasilia - Federal District, a community where fluoride concentration is 0.8 ppm in drinking water. The sample consisted of 833 school children of both sexes, aged between 8 and 12, who have been living in Brasilia since birth. The anterior upper permanent teeth were examined and HOROWITZ fluorosis index was applied to evaluate pathological occurrences. No sex differences were observed in dental fluorosis prevalence. The authors found a high number of dental fluorosis free children (85.36%) and 14.64% of the sample showed light and moderate levels of fluorosis.
