Fluorapatite was formed on the enamel surface of extracted teeth by the gelatin gel method, and a study was made on the influence of salivary constituents and protein membrane on the solubility of the produced fluorapatite by determining the rate of elution of Ca and P. As regards the types of salivary constituents, the rate of elution of Ca and P decreased in the order of albumin solution>lysozyme solution>polyvinyl pyrrolidone solution>mucin solution. As to kinds of protein membrane, the rate of elution of Ca and P increased in the order of mucin aqueous solution<mucin-extracted saliva solution<whole saliva<parotid saliva<extraparotid saliva<albumin aqueous solution, therefore, it is suggested that an interaction of the protein of parotid saliva and mucin being contained in the extraparotid saliva would control the solubility of the produced fluorapatite. Furthermore, it is also implied that whole saliva, compared with parotid saliva and extraparotid saliva, would not act briskly on the solubility of the fluorapatite produced on the tooth surfaces by the gelatin gel method.
