Fang Ling, Zhu Yan-li. Morphological changes of the smear layer after caries removal using different methods: An observation under scanning electron microscope[J]. Chinese Journal of Tissue Engineering Research, doi: 10.3969/j.issn.2095-4344.2013.38.004.
2.1 各组大体观察及探针检查结果 3组去腐后用探针检查窝洞,质地均坚硬,Er:YAG激光组牙本质表面凸凹不平,似山峰状;Carisolv化学机械组牙本质表面光泽较暗,底面较平;传统高速涡轮牙钻组去腐后牙本质表面平整,光亮,并有明显的切割痕迹。 2.2 分析3种方法去腐后扫描电镜观察玷污层清洁度数据 3种方法去除牙本质玷污层清洁度比较差异有显著性意义(P < 0.05),见表2,组间多重比较显示Er:YAG激光组玷污层比Carisolv化学机械组少(P < 0.05),同时也比传统高速涡轮牙钻组少(P < 0.005), Carisolv化学机械组玷污层比传统高速涡轮牙钻组少 (P < 0.05), Er:YAG激光去除玷污层效果最好,见表3。"
