Abstract
The intermediate formation of CaHPO4 · 2H2O and its subsequent conversion to Ca5 (PO4)3F or CaF2 may be a major factor in increased fluoride uptake when tooth enamel is pretreated with acid solutions before being exposed to fluoride. To obtain information concerning the form of fluoride incorporation, the reactions of CaHPO 4 ·2H2O with solutions containing various amounts of F-and PO43- ions were studied.Keywords
