目的分析手术显微镜在疑难根管治疗中的应用效果。方法 84例牙髓病、根尖周病患者,按照治疗方法不同分成对照组与观察组,各42例。对照组应用传统根管治疗,观察组应用牙科手术显微镜根管治疗。对比两组患者的临床治疗效果。结果对照组钙化不通根管、器械分离根管、MB2根管、“C”型根管、失败根管再治疗的成功率分别为23.1%、18.2%、25.0%、20.0%、20.0%;观察组分别为71.4%、70.0%、75.0%、93.3%、75.0%,比较差异均有统计学意义(P<0.05)。结论牙科手术显微镜在疑难根管治疗中的应用效果显著,可明显提高根管治疗的成功率,值得临床推广。
Objective To analyze the effect of surgical microscope in the treatment of difficult root canal. Methods 84 cases of endodontic and periapical disease patients were divided into control group and observation group according to different treatment methods, 42 cases in each group. The control group was treated with traditional root canal therapy, while the observation group was treated with dental surgery microscope. The clinical effects of two groups were compared. Results The successful rates of failed root canal reperfusion were 23.1%, 18.0%, 25.0%, 20.0% and 20.0% respectively in the control group with calcified unreasonable root canal, instrumentally isolated root canal, MB2 root canal and “C” ; The observation group were 71.4%, 70.0%, 75.0%, 93.3%, 75.0%, respectively, the difference was statistically significant (P <0.05). Conclusion Dental surgery microscope in the treatment of difficult root canal treatment effect is significant, can significantly improve the success rate of root canal therapy, is worth clinical promotion.
