title: [Incidence and intensity of mottled teeth (fluorosis) in regions where the drinking water has different contents of magnesium and calcium, respectively (author's transl)].
abstract: A total of 1612 seven- to sixteen-year-olds of both sexes were included in a study of which the purpose was to determine whether different concentrations of magnesium and calcium, respectively, in the drinking water (Ore Mountains) have any effects upon the mottling of the enamel of permanent incisors. It was not possible to determine an epidemiological relationship, but what could be reconfirmed was that the incidence and intensity of mottled teeth correspond with the drinking water fluorine level.
