An electron microprobe study of rat incisor teeth with low or high concentrations of strontium

Abstract

Data accumulated with the electron microprobe has shown that strontium produces decreased mineralization and that an inverse relationship exists between strontium and calcium contents in the rat incisor tooth. Semi-quantitative data on the strontium, calcium and phosphorus contents of enamel and dentine are presented. Sagittal sections of the high-strontium teeth revealed gradients of increasing strontium contents from the incisal to apical areas with phosphorus contents that were relatively constant.
