[The indices of caries and dental fluorosis prevalence in schoolchildren born and permanently living in regions of Azerbaijan differing by the level of the drinking water fluorine content].

Epidemiological survey of schoolchildren born and permanently living in Baku (fluorine concentration in drinking water 0.3-0.5 mg/liter) and in the Azizbekov region at a distance of 30-40 km from Baku (fluorine concentration at least 1.5 mg/liter) was carried out. The incidence of dental diseases was estimated with consideration for environmental factors. High concentration of fluorine in drinking water in the Azizbekov region notably decreases the incidence of dental caries in the studied cohort of children. These data will"help improve organization and planning of dental service, specifically the treatment and prophylaxis measures for children.
