摘　　要：目的:探讨老年磨牙根管的临床检出率,评价口腔手术显微镜(Dental Operating Microscope,DOM)对减少遗漏根管的作用。方法:选取160颗需行根管治疗的第一、二恒磨牙,随机分为常规根管治疗组和显微根管治疗组进行治疗,其中显微组所有操作均在DOM下完成,记录所有患牙的根管数目。结果:常规组老年磨牙4根管总检出率为15%;显微组4、5根管总检出率分别为30%、5%。结论:在老年磨牙的根管治疗中,常规使用DOM能够明显提高磨牙根管的检出率,有效防止遗漏根管的发生。Objective： To investigate the clinical incidence of root canals in molars in elderly patients and the effect of dental operating microscope on reducing missing canals. Methods： A total of 160 teeth in 168 elderly patients were enrolled in the study according to specific selection criteria, and then randomly divided into conventional and microscopic treatment groups, root canal therapy were conducted in both groups. The teeth in microscopic groups were performed under the operating microscope. The number of canals in each molar was recorded. Results： The detection rate of 4 canals in molars in elderly patients for the conventional treatment groups was 15%, while the rate of 4 and 5 canals for the microscopic groups was 30%, 5%, respectively. Conclusion： During root canal therapy in molars in elderly patients, the routine use of dental operating microscope can significantly improve the clinical detection rate of root canals and reduce the incidence of missing canals.
