摘　　要：目的:比较通用粘接剂Single Bond Universal在不同酸蚀模式下应用于V类洞修复充填体边缘的微渗漏程度。方法:选取60颗离体前磨牙,于釉牙骨质界处预备V类洞缺损,随机分为6组,每组10颗牙,分别采用全酸蚀+通用粘接剂、选择性酸蚀+通用粘接剂、无酸蚀+通用粘接剂、全酸蚀+全酸蚀粘接剂(Single Bond2)、选择性酸蚀+自酸蚀粘接剂(Clearfil SE Bond)和无酸蚀+自酸蚀粘接剂处理,均用FilteK Z350XT树脂充填。经冷热循环和亚甲蓝溶液染色后,从颊舌方向平行于牙体长轴正中将充填体纵向剖开,体视显微镜下观察边缘微渗漏程度。结果:所有试件龈壁微渗漏程度均高于牙合壁(P<0.05)。6组龈壁和牙合壁微渗漏程度比较,差异均无统计学意义(P>0.05)。结论:V类洞树脂充填修复时,应用通用粘接剂采用选择性酸蚀模式可获得良好的边缘封闭效果。Aim：To explore microleakage station in class V cavity restoration with universal adhesive（Single Bond Universal）under different acid etching modes.Methods：A total of 60 fresh orthodontically extracted human premolars were collected to prepare class V cavities on the facial surfaces.Then the teeth were divided into six groups（10 in each group）,and dealed with universal adhesive with total-etch,universal adhesive with enamel selective etch,universal adhesive under self-etch mode,Single Bond2 with total-etch,Clearfil SE Bond with selective etch and Clearfil SE Bond,respectively,then were restored with composite resin（FilteK Z350XT）.After thermocycling and dye penetration with methylene blue,all teeth were cut in buccal-lingual direction and the degree of dye penetration was observed under stereomicroscope.Results：The microleakage was more at the gingival margin compared with occlusal margin（P〈0.05）in all teeth.No statistical difference in microleakage degree at the gingival margin or at the occlusal margin was found among all groups（P〉0.05）.Conclusion：Single bond universal adhesive under enamel selective etch for the restoration of class V cavity could obtain better edge sealing effect.
