Surface Enamel Fluoride and Strontium in Relation to Caries Prevalence in Man

Abstract
Surface enamel was analyzed for strontium and fluoride on 439 teeth collected from Ohio and Wisconsin, USA. Mean concentrations were 366.4 μg Sr/g and 1,169.6 μg F/g. A significant, but weak correlation between fluoride concentration and caries as DMFT (r = ––0.16) was found, and also between strontium and fluoride concentrations (r = 0.48). No correlation of strontium in surface enamel and caries was found.
