目的:评价牙科手术显微镜在疑难根管治疗中的应用效果。方法:选取2012年6月-2014年12月期间收治的128颗患牙共330个根管,经过初步评估无法行常规根管治疗或效果不佳,按根管遗漏、根管钙化、器械分离、充填不完善、穿孔分为5组,在牙科手术显微镜辅助下进行治疗,治疗结束后对所有病例进行随访追踪以评价其治疗成功率。结果:探查遗漏根管的成功率为93.62%、疏通钙化根管的成功率为83.95%、取分离器械的成功率为70.59%、根管再治疗的成功率为80.92%、修补穿孔的成功率为81.25%。结论:牙科手术显微镜能有效提高不同类型疑难根管治疗的成功率。
Objective: To evaluate the effect of dental surgery microscope in the treatment of difficult root canal. Methods: A total of 330 root canal of 128 teeth treated in our hospital from June 2012 to December 2014 were selected. After preliminary assessment, the conventional root canal therapy could not be performed or the effect was poor. According to the root canal omission, root canal calcification and instrument separation , Imperfect filling, perforation is divided into 5 groups, with the help of dental surgery microscope treatment, all cases were followed up after treatment to assess the success rate of treatment. Results: The success rate of probing for failed root canal was 93.62%, the success rate of unblocking calcified root canal was 83.95%, the success rate of separating instrument was 70.59%, and the success rate of root canal re-treatment was 80.92%. The successful rate of repairing perforation 81.25%. Conclusion: Dental surgery microscope can effectively improve the success rate of different types of difficult root canal therapy.
