Reactions of Powdered Sound Dentin with Several Fluoride Solutions

Abstract

The reactions between solutions of sodium fluoride, acidulated sodium fluoride phosphate, and hydrofluoric acid and powdered dentin produced mainly calcium fluoride and residual hydroxyapatite. Treatment of powdered dentin with a 10% solution of stannous fluoride produced a new crystalline material identical to that previously described. The formation of fluorapatite on hydroxyapatite of powdered dentin could not be detected under the experimental conditions.
