After topical treatment of enamel pieces cut from bovine incisors, the chemical composition of the solution phases and of the topmost layers of enamel were determined by special techniques of elemental and surface analysis. Fluoride seems to degrade surface enamel when applied in acidic and neutral solutions. Calcium remains immobile on the enamel surfaces, whereas phosphate goes into solution. When treated with acidic solutions (0.05-0.5 mol/l fluoride), a calcium-fluoride-rich phase is precipitated on the enamel surfaces.
对从牛切牙上切下的牙釉质片进行局部处理后，通过特殊的元素分析和表面分析技术测定了溶液相和牙釉质最外层的化学成分。当氟化物应用于酸性和中性溶液中时，似乎会使表面牙釉质降解。钙在牙釉质表面保持不动，而磷酸盐则进入溶液。用酸性溶液（0.05 - 0.5 mol/l氟化物）处理时，富含氟化钙的相沉淀在牙釉质表面。
