Reduction of Enamel Solubility by Sodium Monophosphate

Abstract
Acid-etched human enamel was treated with sodium monofluorophosphate solutions at differing concentrations, pH values, and temperatures and for various time periods. Conditions for optimal enamel solubility reduction are presented. Comparison of the efficacy of sodium monofluorophosphate and sodium fluoride in aqueous solutions and pastes indicated significant superiority of the former.
