Background and Purpose: Fluoride is a natural element essential for human nutrition due to its

benefits for dental enamel. It is well-documented that standard amounts of fluoride in drinkingwater

can decrease the rate of dental caries. This study was conducted with the aim of measuring

fluoride concentration of drinking-water supplies and urban distribution system in Qom, Iran.

Materials and Methods: Results were subsequently compared against national and international

standards. All sources of drinking-water of rural and urban areas were examined. To measure

fluoride, the standard SPADNS method and a DR/4000s spectrophotometer were used.

Results: Results showed that the mean of fluoride concentration in rural areas, mainly supplied

with groundwater sources, was 0.41 mg/L, that of the urban distribution system 0.82 mg/L, that

of Ali-Abad station 0.11 mg/L, and that of the private water desalination system 0.24 mg/L. Due

to the hot climate of Qom, fluoride concentration means of all sources were lower than the

permissible standards set by Iranian Standards and the WHO guidelines (except those of some of

the groundwater sources and urban distribution systems).

Conclusion: It seems that in most of the drinking-water sources the average fluoride concentration is

not enough to prevent dental caries or strengthen dental enamel. It is concluded that Qom’s drinkingwater

would require at least 0.4 mg/L to reach the minimum desirable standard.
