Titanium and Fluoride Concentrations in Titanium Tetrafluoride and APF Treated Enamel

Abstract
Greater fluoride concentrations were obtained in enamel treated with phosphate/fluoride solutions than in that treated with TiF4 at similar pH's (1.0) and F concentrations (0.6M F and 1.6M F). However, fluoride solution without added phosphate at pH 1.0 and 1.6M F concentration produced lower fluoride concentrations in enamel than in TiF4 treated enamel. It is proposed that in TiF4 treated enamel the fluoride uptake may be dependent upon the amount of Ti introduced into the enamel.
