The purpose of this study was to investigate the mineralization mechanism in developing enamel using the pH staining technique. Most of organic components of the enamel decomposed at 580Åa^^~C. Except for the carbonate and hydorogen phosphate groups included in the apatite crystals. In the developing enamel, (Ca+Mg)/P molar ratio was lower than that of the stoichometric hydroxyapatite. Furthermore, amount of carbonates, which were considered to replace the OH and PO4 sites in the apatite crystal, was higher than those in the mattured enamel. The a-axis dimension of the apatite crystals in the secretory stage enamel was confirmed to be greater than those in acidic zone and matured enamel. These results indicated that enamel mineralization followed by decarbonation in carbonate apatite.
