牙釉质经氟化物处理后，表面生成“氟化钙样”的物质（“ＣａＦ＿２－ｌｉｋｅ”ｍａｔｅｒｉａｌｓ）。这种物质为量极少，且采集技术也有困难，故很难利用其作为防龋机理研究的样本。为获取代替牙面的氟化钙样物质，本研究采用化学合成的方法，制备了不同磷含量的氟化钙样物质，并分析、测定了这种物质在醋酸钾缓冲液中的溶解性能。对氟化钙样物质中磷与溶解性能的关系，作了定量的分析，并在其成分、溶解性、晶形结构等方面与纯氟化钙进行了比较。结果表明，用化学方法合成的氟化钙样物质，可以反应对牙面上氟化钙样物质的研究。本研究还验证了磷能使氟化钙样物质的结晶形态从立方晶形转变为微小的球滴状，溶解性随着磷含量的增加而加大。该实验是对氟防龋机理研究的一种方法。
Fluoride-treated enamel produces “calcium fluoride-like” materials (“CaF_2-like” materials) on the surface. It is difficult to use this material as a sample for the study of anti-caries mechanisms, since such substances are extremely rare and difficult to acquire. In order to obtain the calcium fluoride-like substance that replaces the tooth surface, the calcium fluoride-like substance with different phosphorus content was prepared by chemical synthesis method, and the dissolution property of the substance in potassium acetate buffer solution was analyzed. The relationship between phosphorus and solubility in calcium fluoride-like material was quantitatively analyzed and compared with pure calcium fluoride in terms of its composition, solubility, crystal structure and the like. The results show that the chemical synthesis of calcium fluoride-like substances, can respond to the tooth surface of calcium fluoride-like substances. The study also confirmed that phosphorus can change the crystal form of calcium fluoride-like substance from cubic crystal to tiny droplet. The solubility increases with the increase of phosphorus content. This experiment is a method to study the mechanism of anti-caries of fluorine.
