摘　　要：目的对比0.06锥度和0.02锥度主牙胶尖充填镍钛预备的磨牙根管的临床疗效。方法选择因牙髓炎或根尖周炎在北京市顺义区医院口腔科就诊的磨牙229颗,按照就诊顺序随机分为两组,分别采用0.06锥度主牙胶尖(A组)和0.02锥度主牙胶尖(B组)进行冷侧方加压根充,拍摄术后即刻和1年复诊时的X线片,比较两组患牙根充时间、根充质量和1年后的成功率。结果 A组与B组患牙根管充填质量、术后1年复查时的治疗成功率并无显著差异,但A组的根充时间显著小于B组。结论 0.06锥度与0.02锥度主牙胶尖充填磨牙根管的临床治疗效果无差异,但采用0.06锥度主牙胶尖能大大提高临床工作效率。Objective To compare the clinical efficacy of 0.06 tapered and 0.02 tapered master gutta-percha cone filling molar canals instrumented by ProTaper.Methods 229 molar teeth with pulpitis or periapical diseases in our hospital were selected and divided into two groups randomly,which were obturated respectively with 0.06 tapered（group A） and 0.02 tapered（group B） master gutta-percha cone by the cold lateral condensation technique.Every tooth＇s X-ray radiographs of immediate postoperative and one-year follow-up were taken.The obturation time of tooth,the quality of root filling and success rate at one-year follow-up of the two groups were recorded and compared.Results There were no statistical significance in the quality of root filling and success rate at one year follow-up between group A and B,while the obturation time of tooth of group A was significantly less than that of group B.Conclusion No clinical difference is found when molar canals are obturated with either 0.06 tapered or 0.02 tapered master gutta-percha cone,but clinical work efficacy is greatly improved by using 0.06 tapered master gutta-percha cone.
