| 摘 要： | 目的探讨冷光美白对人恒牙表层釉质晶体和显微结构的影响。方法人离体恒牙经冷光美白处理后,使用微区X线衍射仪、傅里叶转换红外光谱仪和扫描电镜观察,分析美白前后表层釉质在晶体和显微结构上发生的改变。结果经冷光美白处理后,人恒牙表层釉质晶体尺寸变小,结晶度降低,表面孔隙变得不规则,并出现浅碟状凹坑。结论冷光美白技术可能导致人恒牙表层釉质晶体和显微结构发生类似于脱矿的改变。

| Abstract: | Objective To study the effects of the cold-light bleaching technique on crystals and microstructure of the dental enamel.Methods The human premolars extracted for orthodontic reasons were treated by a standard cold-light bleaching procedure.After the treatment,all samples were detected by high resolution micro-area X-ray diffractometer,Fourier transform infrared spectroscope and scanning electron microscope.Results After the permanent teeth were treated with cold-light bleaching technique,the enamels' cryst... |
