摘　　要：目的:观察显微超声技术联合C型先锋锉治疗老年弯曲钙化阻塞根管的临床疗效。方法:回顾性收集2022年5月~2023年5月临床明确诊断为弯曲钙化阻塞根管,在本院行显微超声技术联合C型先锋锉治疗的122例老年患者资料(共142颗患牙,238个钙化根管),对不同牙位、不同钙化部位的根管疏通成功率、治疗时间、患牙术后疼痛及并发症情况进行统计分析,评价显微超声技术联合C型先锋锉治疗老年弯曲钙化阻塞根管的疗效及安全性。结果:238个弯曲钙化根管治疗后,总疏通率为84.87%,其中前牙、前磨牙及磨牙的根管疏通成功率分别为82.76%、87.34%、83.85%,根管冠1/3、根管中1/3及根尖1/3的根管疏通成功率分别为87.60%、81.93%、82.35%。不同牙位、不同钙化部位的根管疏通率比较,差异均无统计学意义(P>0.05)。所有疏通根管均顺利完成根管治疗,单个钙化根管的平均疏通耗时为(38.56±7.51)min,根管充填时间为(95.70±15.57)s。以患牙为评价单位,术后急性疼痛发生率为7.75%(11/142),总并发症发生率为1.41%(2/142)。结论:采用显微超声技术联合C型先锋锉治疗老年弯曲钙化阻塞根管,根管疏通率高,患牙术后急性疼痛、并发症发生率低,值得临床优先选择。Objective:To observe the clinical effect of microscopic ultrasonic technique combined with C-pilot file in the treatment of curved calcified/obstructive root canals in the elderly.Methods:The data of 122 elderly patients(a total of 142 affected teeth that 238 calcified root canals)who were clinically diagnosed with curved calcified/obstructive root canals from May 2022 to May 2023 and underwent combined treatment with microscopic ultrasonic technique combined with C-pilot file in our hospital were collected retrospectively.Statistical analysis was conducted on the success rates of root canal dredging in different tooth positions and at different calcified sites,treatment time,postoperative pain of affected teeth and the incidence of complications.Effect and safety of microscopic ultrasonic technique combined with C-pilot file in the treatment of curved calcified/obstructive root canals in the elderly were evaluated.Results:After treatment,the total patency rate of 238 curved calcified root canals was 84.87%.The success rates of root canal dredging for anterior teeth,premolars,and molars were 82.76%,87.34%,and 83.85%,respectively.The success rates of root canal dredging for crown 1/3,middle 1/3,and apex 1/3 were 87.60%,81.93%,and 82.35%,respectively.There was no statistically significant difference in the root canal patency rate in terms of different tooth positions and different calcified sites(P>0.05).All root canal treatments were successfully completed.The mean time for dredging and time for root canal filling was(38.56±7.51)min and(95.70±15.57)s,respectively.Based on the evaluation unit of the affected tooth,the incidence of postoperative acute pain was 7.75%(11/142),and the total incidence of complications was 1.41%(2/142).Conclusion:Applying microscopic ultrasonic technique combined with C-pilot file to treat curved and calcified/obstructive root canals in the elderly can achieve a high root canal patency rate.Besides,the incidence rates of postoperative acute pain and complications are low,making the tre
