title: Reactions of powdered human enamel and fluoride solutions with and without intermediate CaHPO4 x 2H2O formation.
abstract: Powdered human enamel treated for three minutes each with a CaHPO4 x 2H2O forming solution and a fluoride solution, and then suspended in "synthetic saliva" for 72 hours acquired a large amount of apatitic fluoride. This apatitic fluoride appears to form after the fluoride treatment.
