MicrosoftInternetExplorer4 Background and Objectives: Intake of high concentrations of fluoride in drinking
water can cause dental fluorosis. In this study, the prevalence of dental
fluorosis in rural communities of East
Azerbaijan Province
was studied.
Materials and Methods: 3 villages of Bashsizkooh, Bostanabad (fluoride concentration in drinking water = 0.12 mg/L), Nagharehkub, Ahar (current water resource = 0.6 mg/L, old water resource = 1.1-1.2 mg/L), and Gharehbolaq, Jolfa (current water resource = 0.35 mg/L and old water resource = 2.4 mg/L old source) were selected as low, medium, and high exposure to fluoride respectively. All village residents above 6 years old were visited by physician. Quality of water resources was determined by referring to the records archived and through conducting new analysis.
Results: Dental fluorosis was observed in 62.7 % of the people visited. In 31.5% of participants, fluorosis Grade 1 in 22.4 % of participants, fluorosis grade 2 in 7.7 % of participants, fluorosis grade 3 and finally fluorosis grade 4 was observed in 4 patients. Different levels of fluorosis were observed in residents of the villages of Gharebolaq, Nagharehkub, and Bashsizkooh (83.3%, 70.5 %, and 32.5 % respectively). There was a significant difference in prevalence of fluorosis between villages (P < 0.001). Fluorosis was observed in both permanent and temporary teeth. Mean cumulative fluoride index (MCFI) in people with and without fluorosis was 22660.2 and 4743.2 mg, respectively. There was a correlation between this index and fluorosis (R =0.413).
Conclusion: In all three villages studied, even Bashsizkooh, different grades of fluorosis were endemic. It is recommended that the responsible authorities take a new measure and approach for the intake of fluoride from drinking water.
