牙本质透明层的X射线能谱分析

Analysis of inorganic composition in the transparent layer in dentinal carious lesion by using energy dispersed X-ray spectrometry(EDS)

目的 探讨牙本质透明层矿化物的变化。方法 应用eXL型电镜数据处理系统 (EDS)和扫描电镜 ,对 6个样品的牙本质透明层和正常牙本质的无机物成分进行分析。结果 牙本质透明层的Ca/P(重量比 )比值明显高于正常牙本质 (P =0 .0 0 2 )。

Objective To study the mineralization of transparent layer in dentinal carious lesion.Methods Anaysis of inorganic composition by using of eXL electronic microscopic data process system(EDS) and scanning microscopy.Results Ca/P (W/W) ratio in transparent layer in dentinal carious lesion was significantly higher than normal dentin (P= 0.002 ).Conclusion Mineralization in transparent layer in dentinal carious lesion is higher than normal dentin.
