摘　　要：目的:了解排龈法充填后牙邻面洞的临床疗效。方法:选择2008年5月～2010年4月就诊并复诊的后牙邻面患龋牙261颗,按照2∶1比例,随机分为实验组及对照组。实验组先用排龈线排龈,再用进口松风玻璃离子水门汀粘固剂垫底,凝固后重新制洞并用Ag-Hg合金或光固化复合树脂充填。对照组不排龈,直接进行预备充填,方法同实验组。结果:实验组174颗患牙中,失败10颗,成功164颗。对照组87颗患牙中,16颗失败,成功者71颗。实验组成功率显著高于对照组(P<0.05)。结论:排龈法充填后牙邻面洞可使充填体松动、折断、脱落等失败情况明显减少,密合更好,较少继发龋形成及牙龈发炎,值得临床推广。Objective：To investigate the effect of filling buccal tooth caries in distal proximal surface by gingival retraction.Methods：A total of 261 buccal teeth with proximal dental caries were selected from May 2008 to April 2010.They were randomly divided into experimental group and control group by 2：1.Teeth in experimental group were treated by gingival retraction line,and by imported glass ionomer cements as rebase.After solidification,the cavity preparation was made again,and Ag-Hg alloy or light-cured composite resin was used for filling.While only filling without gingival retraction was performed in control group.Results：Out of ill 174 teeth,164 showed successful result and 10 failed in experimental group.While in control group,there were 71 successful cases and 10 failure cases（P0.05）.Conclusions：Filling buccal tooth caries in distal proximal surface by gingival retraction can prevent from loosening,fracture and shedding of filling material,provide better sealing,and decrease incidence of secondary carries and gingivitis.So it is worthy extensive clinical application.
