Drinking water provides many vital elements for the human body, but the presence of some of dissolved elements rather than permissible concentration can endanger human health. Among the dissolved elements of drinking water, fluoride is noticeable, because both the very low or very high concentration of it has adverse health impacts including dental caries and its concentration should be at an acceptable level. The purpose of this research was to determine the fluoride concentration in drinking water of Mianeh city in 2008.This cross-sectional research was carried out on all sources of drinking water (14 groundwater sources) in Mianeh in 2008. The results show that the mean of source fluoride concentration in spring, summer, autumn, and winter was 0.295 ± 0.039 mg/l, 0.47 ± 0.17 mg/l, 0.48 ± 0.18 mg/l, and 0.4 ± 0.06 mg/l, respectively. Moreover, the concentration of fluoride in all sources was below the permissible concentration level based on Iran drinking water standards, but they were in standard range proposed by WHO. In addition, the DMFT index of the children between 6 and 9 years old in Mianeh was higher than Iran DMFT index.
