Copper(II) fluoride is an inorganic compound with the chemical formula CuF2. It is a white or green, crystalline, hygroscopic solid.
The tooth mineral hydroxyapatite de-composes and calcium fluoride adheres tothe apatite and can serve as a source of flu-oride for subsequent conversion of hydroxy-apatite to fluorapatite.6Recently there has been interest in theapplication of physical chemistry principles to hydroxyapatite, the primary mineral of teeth.ith the aid of a computer, it ispossible to calculate initial rates of reactionthat can be used to evaluate a priori thefluoride uptake potential of various fluoridesolutions. The variables that can be exam-ined are the fluoride concentration, phos-phate concentration, pH, buffer type (pKa), and buffer concentration.
