Aim : To assess point prevalence of dental fluorosis and dental caries and their interrelationship in children of age group 10 to 14 years from areas in Lucknow district with low (0-0.5 mg/1), moderate (0.5-1.1 mg/1) and high (>2 mg/1) concentration of fluoride in drinking water. Material & Methods: Atotal of 531 school going children were included in the study. Dental caries and dental fluorosis was recorded (WHO, 1997) under standardized conditions. All children residing in their respective areas since birth were included and only permanent teeth were examined. Intra-oral examination was carried by single examiner. Results: Mean DMFT was found to be 2.21,0.96 and 0.78 whereas mean CFI was found to be 0, 0.02 and 0.36 from the three areas respectively. A statistically significant (p<0.001) difference was observed in caries prevalence in low fluoride area as compared to other two areas whereas dental fluorosis prevalence in high fluoride area was found to be highest and also statistically significant (p<0.001) from other two areas. Conclusion: It was concluded that dental caries increases with increasing severity of fluorosis in low, moderate and high fluoride areas. Thus a positive relationship is seen between dental caries and dental fluorosis in all three areas.
