摘要：

目的 比较前牙唇侧入路一次性根管治疗与传统的根管治疗的临床疗效与冠折率。方法 将2007年4月至2008年10月山西医科大学第二附属医院就诊的102例因牙齿根面龋和楔状缺损引起前牙慢性牙髓病变、根尖病变的患者随机分成两组，51例采用传统的根管治疗方法，51例采用前牙唇侧入路碧兰糊剂一次性根管治疗，对其术后的冠折率和愈合率进行对比和观察。结果 前牙唇侧入路一次性根管治疗的成功率为90.20%，传统的根管治疗成功率为86.27%，两组治疗效果差异无统计学意义 （P＞0.05）。传统的根管治疗冠折率为9.80%，前牙唇侧入路一次性根管治疗冠折率1.96%，两组冠折率比较有差异有统计学意义（P＜0.05）。结论 前牙唇侧入路一次性根管治疗的成功率与传统的根管治疗无差异，但术后冠折率低，且减少了患者的复诊次数，满意效果。

Abstract:

Objective To compare clinical effects and crown fracture rate using two different methods in root canal therapy. Methods A total of 102 cases who were diagnosed as chronic pulpitis or chronic periapical periodontitis caused by wedge-shaped defect and root surface caries in Stomatology Clinic of the Second Affiliated Hospital of Shanxi Medical University during the period from April 2007 to October 2008 were invited to participate the survey .According to the selective standards ，they were divided into two groups with 51 cases of each group randomly ，treated by labial path root canal therapy（experimental group） and traditional therapy（control group） respectively. Result The success rate of one-visit root canal therapy of anterior teeth via labial path is 90.20%;the success rate of traditonal therapy method was 86.27%;the success rate showed no significant difference beween two groups. （P＞0.05）. However， the crown fracture rate of traditonal therapy method was 9.80% and the rate of the experimental group was 1.96%， the former being significantly higher than the latter（P＜0.05）. Conclusion The one-visit root canal therapy via labial path is feasible in chronic pulpitis or chroniac periapical periodontitis of anterior teeth ，and can decrease the crown fracture rate and the times of seeing a doctor ， winning the patients’compliments.
