Abstract:

The aim of this study was to evaluate the prevalence and the severity of dental fluorosis of individuals among 11-14 year olds in Teresina, PI, Brazil, tropical city with fluoridated drink water. This was a cross-sectional observational study. The sample consisted of 571 students of public and private schools. The consent for the data collection was obtained and the exams were carried out at the schools. Data were registered in a form answered by the parents, regarding the socioeconomic, demographic characteristics and the oral hygiene habits of the sample.The used Thylstrup Fejerskov (TF) index was used (kappa coefficient = 0.83). The prevalence of fluorosis was 78.3%, and only 12.5% of the affected children had TF&#8805; 3 (with aesthetic compromising). To be born and to live in Teresina increased the odds 2.70 times (95% CI = 1.04 to 7.00) of having severe fluorosis (TF&#8805;3) and to study in public school increased the chances of having fluorosis in 2,82 times (95% CI = 1.39 to 5.72). Thus, the prevalence of fluorosis was high, but the severity was low. It is necessary to have a periodic monitoring of this dental condition and to control of the fluoridation level of the drinking
