The Reaction of Stannous Fluoride and Hydroxyapatite

Abstract

Systematic investigation of the chemical reaction of a slurry of SnF2, Ca10(OH)2(PO4)6, and H2O shows that products other than CaF2 are determined by the relative concentrations of the reactants. In addition to Sn2OHPO4, and Sn3F3PO4, a previously unreported compound, Ca(SnF3)2, has been observed as a product of the reaction.
