摘要/Abstract

摘要： 目的观察研究Beyond冷光美白治疗对活髓牙釉质表面超微结构的影响。方法以3位患者上颌前牙为研究对象，分别在冷光美白治疗前，治疗后即刻以及治疗后3个月取印模，复模，扫描电镜观察牙釉质超微结构变化。结果扫描电镜下发现冷光美白治疗后即刻牙釉质表面超微结构出现浅表蚀刻样或微孔状轻微脱矿改变，占77.89%（P<0.05)；3个月后其牙釉质表面超微结构改变较即刻时有减轻,占44.4%（P<0.05)。结论冷光美白治疗对牙釉质具有轻微脱矿作用，导致牙釉质表面超微结构的改变，这种超微结构改变在体内唾液环境下可以随着时间推移逐渐再矿化而减轻

Abstract: Objective To evaluate the effect of Beyond Cold Light Whitening on the ultrastructure of enamel surface. Methods Impressions of three patient′s upper incisors were taken before,immediately after and three months after Beyond cold light whitening treatment.Epoxy resin replica was made to analyze the bleached enamel surfaces with scanning electron microscopy. Results The SEM findings revealed that mild demineralization changes such as the pitting and micro-porosity were observed on the enamel surface immediately after and three months after bleaching and the ultrastructural changes become less obvious three months after whitening. Conclusions The Beyond cold light whitening might result in the micro morphological changes of the bleached enamel surfaces.The bleached enamel with the micro morphological changes could be re ?ineralized in vivo over time.
