Abstract
Summary
The solubility of powdered human tooth enamel was measured after treatment with stannous fluoride, sodium fluoride, sodium N-palmitoyl sarcosinate, sodium de-hydroacetate, or sodium oxalate by a method which measures the amount of phosphorus dissolved from the treated enamel by acetic acid. The data indicate that stannous fluoride is markedly superior to sodium fluoride and that the sarcosinate is of only questionable value in its ability to reduce powdered enamel solubility. Sodium dehydroacetate and sodium oxalate were without effect in decreasing the solubility of powdered enamel.
