Dental caries and mottled enamel among Formosan children

Abstract

A survey of dental caries and mottled enamel was carried out among Formosan children. The prevalence of dental caries was approximately half that of western civilized countries. In areas where the water contained fluoride naturally, the prevalence of dental caries was inversely related to the fluoride content of the water supply. Mottled enamel was prevalent and to a greater extent than could be accounted for by the fluoride content of the water consumed. The relation between dental caries and mottled enamel was examined in connexion with the most suitable fluoride level to be employed in an artificially fluoridated water supply. The contribution of fish to the fluoride intake is discussed and the value of reducing the prevalence of dental caries in less developed countries is emphasized.
