The purpose of this study was to comparatively evaluate the effects of different caries removal methods on microleakage success of class V adhesive restorations by means of light microscopy (stereomicroscope) and scanning electron microscopy (SEM) observations. Sixty-four human teeth with class V caries that measured with DIAGNOdent were used. The samples were divided into four groups (n = 16) randomly according to caries removing methods of conventional method, Carisolv, Papacarie, and Er,Cr:YSGG laser system. The self-etch Clearfıl SE Bond and Clearfıl Majesty Es-II were used as restoration materials. After thermal cycles of 2,000 (5 and 55°C) samples were immersed in a 50% wt/wt AgNO Samples were finally imaged and scored under light microscopy and SEM, respectively. The data were statistically analyzed using Kruskal-Wallis H, pairwise comparison and Wilcoxon's T tests at 5% significance level (p < .05). Statistical analysis demonstrated that there was no significant difference between microleakage scores in dentin regions but there were significant difference between the Papacarie and Er,Cr:YSGGlaser in terms of leakage scores in enamel sites. No statistically significant difference in leakage scores emerged between light microscopy and SEM.
本研究旨在通过立体显微镜和扫描电子显微镜观察，比较不同龋坏去除方法对 V 类洞型复合树脂修复体微渗漏效果的影响。选择 64 颗 DIAGNOdent 测量有 V 类龋坏的人磨牙，随机分为四组（每组 16 颗），根据常规方法、Carisolv、Papacarie 和 Er,Cr:YSGG 激光系统的龋坏去除方法进行分组。使用自酸蚀 Clearfıl SE Bond 和 Clearfıl Majesty Es-II 作为修复材料。在热循环 2000 次（5 次和 55°C）后，将样本浸泡在 50% wt/wt AgNO 中。最后，分别在立体显微镜和扫描电子显微镜下对样本进行成像和评分。使用 Kruskal-Wallis H、两两比较和 Wilcoxon T 检验在 5%的显著性水平（p <.05）进行统计分析。统计分析表明，牙本质区域的微渗漏评分无显著差异，但在牙釉质区域，Papacarie 和 Er,Cr:YSGG 激光之间的渗漏评分存在显著差异。在微渗漏评分方面，立体显微镜和扫描电子显微镜之间没有统计学差异。
