title: [The effect of fluorine and other biogeochemical factors on enamel and dentin microhardness].
abstract: Dental enamel and dentin microhardness were studied in subjects aged 35-44 living in various climatic and geographic zones of Azerbaijan. A total of 172 intact teeth were examined. Dental hard tissue microhardness was found to be related to caries intensity, fluorine content in potable water, and to other biogeochemical factors. Enamel and dentin microhardness were found much higher in the areas with high fluorine levels of potable water than in those with fluorine-deficient water.
