[Caries prevalence in preschool children in industrial cities]. / Rasprostranennost' kariesa u detei doshkol'nogo vozrasta promyshlennykh gorodov.

Caries incidence was analyzed in preschool children attending kindergartens living in two industrial towns differing by the level and specific features of air pollution and by fluorine levels in potable water. Caries incidence was found to be higher in a ferrous metallurgy center with very low (0.1 to 0.3 ml/l) fluorine levels in potable water. Passive smoking factor was found to contribute to development of caries in children, particularly so in girls. Motor car transport effects on caries development in children were not confirmed. Recommendations on reduction of caries development intensity are suggested.
