摘要
目的通过对槟榔牙表面着色沉积物的成分分析,探究槟榔牙着色的可能原因。方法利用X射线荧光光谱(XRF)分析槟榔牙表面着色沉积物的元素组成;借助傅里叶变换红外光谱仪(FTIR)分析着色沉积物中可能的有机成分。结果着色区域含有O、C、Ca、P、S、Cl、Fe、Mn、Na等元素。着色区域有机成分中可能含有蛋白质、磷酸根、磷酸一氢根、碳酸根。结论槟榔牙无机着色与Fe、Mn、S元素相关,有机着色可能与蛋白质氧化有关。
Objective To explore the possible reasons for betel tooth discolouration by composition analysis.Methods A nalyze chemical elements in the stained deposition by XRF.A nalyze possible or-ganic ingredients in the stain deposition by FTIR.Results The stained area contains O,C,Ca,P,S,Cl,Fe,Mn,Na,protein,PO4 3,HPO4 2-,and CO3 2-.Conclusion Betel tooth discolouration is due to Fe,Mn,S and protein.
