Background and aims. The aim of the present study was to compare the effect ofsurface treatment with Er; Cr:YSSG, Nd:YAG, and CO2 lasers on repair shear bond strength of a silorane-based composite resin. Materials and methods. Sixty eight cylindrical samples of a silorane-based composite resin (Filtek Silorane) were pre-pared and randomly divided into 4 groups as follows: group 1: without surface treatment; groups 2, 3 and 4 with surface treatments using Er; Cr:YSSG, Nd:YAG, and CO2 lasers, respectively. A positive control group (group 5) was assigned in order to measure cohesive strength. Repair shear bond strength values were measured and data was analyzed using one-way ANOVA and a post hoc Tukey test at a significance level of α=0.05. Results. There were statistically significant differences in repair shear bond strength values between group 2 and other groups (P < 0.05); and between group 1and groups 3and 4 (P < 0.001); however, there were no significant differences be-tween groups 3 and 4 (P = 0.91). Conclusion. The repair shear bond strength of silorane-based composite resin was acceptable by surface treatment with lasers.
背景与目的。本研究旨在比较铒铬钇钪石榴石激光（Er,Cr:YSSG）、钕钇铝石榴石激光（Nd:YAG）和二氧化碳激光对一种硅氧烷类复合树脂修复体剪切粘结强度的影响。材料与方法。制备了68个硅氧烷类复合树脂（Filtek Silorane）圆柱形样本，并随机分为4组，如下：第1组：未进行表面处理；第2、3和4组分别使用Er,Cr:YSSG、Nd:YAG和二氧化碳激光进行表面处理。设置了一个阳性对照组（第5组）以测量内聚强度。测量修复体剪切粘结强度值，并使用单因素方差分析和事后Tukey检验在显著性水平α=0.05下对数据进行分析。结果。第2组与其他组之间的修复体剪切粘结强度值存在统计学显著差异（P < 0.05）；第1组与第3组和第4组之间也存在显著差异（P < 0.001）；然而，第3组和第4组之间没有显著差异（P = 0.91）。结论。硅氧烷类复合树脂的修复体剪切粘结强度通过激光表面处理是可以接受的。
