摘要
目的研究涎石的成分结构，探讨其形成原因。方法利用红外吸收光谱仪和Ｘ线衍射仪分别对１２例颌下腺涎石化学成分进行分析研究。结果涎石的结构成分是多种化合物的混合物，其中主要成分是羟磷灰石、正磷酸钙、氟磷灰石、透磷钙石、碳酸磷灰石、羟碳酸磷灰石和有机物质。结论涎石形成既与细菌感染有关，更与唾液性质（ｐＨ值、流速和所含蛋白质浓度）有关。
Objective To investigate the composition and structure of sialolith and explore the contributing factors of sialolith. Methods 12 specimens of sialolith of the submandibular salivary glands were analysed by infrared spectrometry and X ray powder diffraction. Results The sialolith was mixture of such inorganic substance as hydroxyapatite, whitlockite and organic matter. Conclusion The contributing factors of the sialolith were associated with the bacterial infection and the nature of the soliva (pH velocity of flow and consistency of protein).
