Aims and objectives: (i) To assess the prevalence of dental fluorosis among the school children (ii) To estimate fluoride level in drinking water source in Enjilgere village known for endemic flourosis. (iii) comparison of two indices measuring dental fluorosis. Study subjects and Methods: 125 school children of government school were included. Demographic data was collected followed by general and oral examinations. Prevalence of dental fluorosis was assessed using Deans Fluorosis index (T.H.Dean, 1942) and Severity was assessed using Tooth Surface Fluorosis Index (TSIF)(Horowitz, 1986). Water samples were collected and fluoride in water was assessed in Public Health Institute. Results: The overall prevalence of dental fluorosis was 69.3%. The mode of Dean's Score for Dental Fluorosis was 2, highest score was 4 and for TSIF score was 2 but the severity assessed by TSIF was score 7. The fluoride content of the drinking water samples ranged from 1.57-2.22 ppm Conclusion: Increase in fluoride concentration in the drinking water, resulted in increased prevalence of Dental Fluorosis in this village and TSIF was more sensitive index for assessing dental fluorosis .
