Radioactive Phosphate Absorption By Dentin and Enamel

Abstract
A study of the relative amt. of radioactive P which is absorbed by enamel and different topographic and morphologic varieties of dentin has been ascertained. Both in vitro and in vivo prepns. show a direct relationship between variation in the morphology of dentin and the absorption of radioactive P. The absorption of P32 is in-versely related to the density of the dentin. The relative amts. of Psa absorbed were observed to be similar for the enamel and the several topographic and morphologic varie-ties of dentin which were studied.
