The purpose of this study was to evaluate the efficiency of the Er:YAG laser and diamond bur cavity preparation on the marginal microleakage of Class V cavities. Group 1: bur preparation (bp) + Vertise Flow (VF); Group 2: laser preparation (lp) + VF; Group 3: bp + Adper Easy One (AEO) + Filtek Ultimate Flowable Composite (FUFC); Group 4: lp + AEO + FUFC; Group 5: bp + Clearfil S3 Bond (CSB) + Clearfil Majesty Flow (CMF); Group 6: lp + CSB + CMF. Data were analyzed by Kruskal-Wallis and Mann-Whitney U tests (p < .05). More microleakage was observed in cervical regions compared to occlusal regions in all groups (p < .05). No significant difference was observed among all groups in terms of occlusal and cervical surfaces, respectively (p > .05). The use of the Er:YAG laser for cavity preparation with different adhesive systems and flowable composites did not influence microleakage.
本研究的目的是评估铒钇铝石榴石（Er:YAG）激光和金刚砂车针制备Ⅴ类洞对边缘微渗漏的影响。第1组：车针制备（bp）+Vertise Flow（VF）；第2组：激光制备（lp）+VF；第3组：bp+Adper Easy One（AEO）+Filtek Ultimate Flowable Composite（FUFC）；第4组：lp+AEO+FUFC；第5组：bp+Clearfil S3 Bond（CSB）+Clearfil Majesty Flow（CMF）；第6组：lp+CSB+CMF。数据采用Kruskal-Wallis检验和Mann-Whitney U检验进行分析（p<0.05）。所有组中，与牙合面相比，颈部区域观察到更多的微渗漏（p<0.05）。在牙合面和颈部表面方面，所有组之间分别未观察到显著差异（p>0.05）。使用Er:YAG激光联合不同的粘结系统和可流动复合树脂进行窝洞制备不会影响微渗漏。
