研究牙釉质的化学结构对龋病的研究有密切关系。只有了解牙釉质内部的系统的化学变化及其对龋患率的可能影响,才能阐明龋病的发病机制。牙釉质内含大量的仅在电子显微镜下可以看到的无机物质—结晶体。这些结晶体中主要有与磷灰石相似的磷酸钙;还可能有一些低钙磷灰石的结构以及一些非磷灰石的结晶。牙釉质矿物中含钙、磷酸及氢氧离子组成氢氧磷灰石。事实上有些氢氧离子始终未被结合以致能不断加速化学反应,而另一部分可以被氟所取代,钙和磷酸离子亦会被取
The study of the chemical structure of enamel is closely related to the study of dental caries. Only understanding the chemical changes in the enamel system and its possible impact on the caries rate in order to elucidate the pathogenesis of dental caries. Enamel contains a large number of inorganic substances that can be seen only under the electron microscope - crystals. There are mainly calcium phosphates similar to apatites in these crystals; some low-calcium apatite structures and some non-apatite crystals are also possible. Enamel mineral calcium, phosphoric acid and hydroxide ions constitute hydroxyapatite. In fact, some of the hydroxide ions have not been combined to accelerate the chemical reaction, while the other part can be replaced by fluorine, calcium and phosphate ions will be taken
