Abstract
Etched enamel surfaces were treated topically with combinations of acid phosphate fluoride and stannous fluoride solutions, and then exposed to constantly recirculated neutral calcium phosphate solutions. The calcium, phosphate, fluoride, and hydrogen ion reactions with the variously treated surfaces were compared. Results showed concurrent dissolution of calcium fluoride and diffusion of hydrogen fluoride from the surfaces, and indicated concurrent deposition of apatitic mineral into the surfaces.Keywords
