Fluorine, Ash, Calcium, and Phosphorus in Human Teeth

Abstract

The ash, Ca and P content of human enamel and dentin did not vary with caries experience or age. An 8-fold increase in enamel-fluorine was not related to any change in enamel-ash, -Ca or -P. A 10-fold increase in dentin-fluorine was not related to any change in dentin - Ca and -P. There was a slight increase in the ash content of highly fluorosed dentin.
