目的评价4种黏结剂对氧化锆全瓷嵌体边缘微渗漏的影响。方法选取2012年8月佛山市禅城区向阳医院口腔科新鲜拔除的上颌第三磨牙40颗，随机分为A、B、C、D组，每组10颗，制备Ⅴ类洞形。4组离体牙分别采用全酸蚀黏结剂Adper Singlebond 2（A组）及自酸蚀黏结剂ClearFil SE Bond（B组）、Multilink Sprint（C组）和Adper Easy One（D组）黏结氧化锆全瓷嵌体，修复后离体牙经冷热循环后行2%亚甲基蓝染色，根管显微镜下观察各组微渗漏程度并进行比较。结果在牙合壁，C组微渗漏明显高于A和B组，差异均有统计学意义（P<0.05）；但与D组差异无统计学意义（P>0.05）。在龈壁，C组微渗漏明显高于其他3组，差异均有统计学意义（P<0.05）；而其他3组之间差异均无统计学意义（P>0.05）。结论自酸蚀黏结剂ClearFil SE Bond和Adper Easy One的封闭能力较好，且较全酸蚀黏结剂操作简单方便，推荐临床使用。

Objective To evaluate the microleakage and penetration ability of zirconium oxide inlays using different self-etching bonding agents in vitro. Methods Forty caries-free extracted human third molars were randomly divided into four groups with ten teeth each. Class V cavities were prepared on the buccal surfaces of forty human extracted third molars using diamond burs. The zirconium oxide inlays were placed with Adper Singlebond 2,ClearFil SE Bond,Multil-ink Sprint and Adper Easy One. The microleakage scores were examined on the occlusal and gingival margins at 30 × magnification after each sample was stained. Results Statistically significant differences were observed between the groups in both occlusal and gingival margins. Microleakage scores of Multilink Sprint were significantly higher than other groups on both margins. Group of ClearFil SE Bond and Adper Easy One showed no statistical differences with etch-and-rinse resin cement. Conclusion ClearFil SE Bond and Adper Easy One show comparable microleakage re-sults with etch-and-rinse resin cement.
