摘要
目的:试用Meta分析研究Nd:YAG激光表面处理对树脂粘接剂与氧化锆粘接强度的影响,为提高树脂粘接剂与氧化锆的粘接强度提供循证证据。方法:通过计算机检索PubMed、Cochran Library、EMbase、CNKI、维普、万方等数据库,查找Nd:YAG激光表面处理氧化锆的相关研究,采用RevMan5.2软件对纳入的研究进行Meta分析。结果:共纳入8个研究,合计290个样本。Meta分析结果显示:Nd:YAG激光表面处理组与对照组比较,剪切粘接强度(P=0.02)和粗糙度(P=0.0001)均高于对照组,差异有统计学意义;Nd:YAG激光表面处理组的剪切粘接强度与Al_2O_3喷砂组比较,差异无统计学意义(P=0.87),Nd:YAG激光表面处理组的粗糙度高于Al_2O_3喷砂组,差异有统计学意义(P=0.02)。结论:Nd:YAG激光表面处理能增加树脂粘接剂与氧化锆的粘接强度,但目前尚不能认为Nd:YAG激光表面处理优于Al_2O_3喷砂处理。
Objective： To evaluate the bond strength between resin cement and zirconia after Nd： YAG laser surface treatment by a Meta-analysis method. Methods： By searching PubMed, Cochrane Library, EMbase, CNKI, VIP, Wanfang database for the studies on Nd： YAG laser and bond strength between resin cement and zirconia, Meta-analysis were conducted using RevMan5.2 software. Results： A total of eight studies involving 193 samples were included. Meta-analysis showed that the shear bond strength of the Nd： YAG laser group is significantly higher than the control group （SMD=2.12, 95%CI[0.41, 3.83], P= 0.02）. The surface roughness of the Nd：YAG laser group is significantly higher than the control group （SMD=6.55, 95%CI[3.22, 9.89], P= 0.0001）. There were no significant differences in shear bond strength between Nd： YAG laser group and Al2O3 sandblasting group （SMD=0.21, 95%CI[-2.19, 2.61], P= 0.87）, Nd： YAG laser group＇s Surface roughness is significantly higher than the Al2O3 sandblasting group （SMD=5.55, 95%CI[0.99, 10.12], P= 0.02）. Conclusion： Nd： YAG laser may increase the bonding strength of the resin cement and zirconia while it is not clear whether Nd： YAG laser is better than Al2O3 sandblasting on the bond strength between resin cement and zirconia.
