Prevalence of dental caries and co-relation with fluorosis in low and high fluoride areas.
The aim of the study was to determine the degree of caries prevalence in the permanent dentition and the accompanying fluorosis in children between 6-16 years of age in both low (0.5 ppm) and relatively high (1.2 ppm) fluoride areas. In 3605 children in a low fluoride area (Dharwad), the mean DMFT was 0.65; 77% of the children were caries free. Grade I fluorosis (using Dean's fluorosis inded) was observed in only 0.66% of the children. Among 3618 children of similar age groups, living in high fluoride areas (Gadag), 84% were caries free and the mean DMFT value was 0.39. Varying degrees of fluorosis were present in 57.07% of the children. The results of the study suggest a definite relationship between the amounts of fluoride ingested through water and caries experience observed in the population.
