目的:探讨应用C型先锋锉结合超声器械及根管显微镜(DOM)处理钙化阻塞根管的临床疗效。方法:对81例钙化阻塞根管的患者采用C型先锋锉结合专用超声器械及根管显微镜进行根管疏通,统计治疗成功率。结果:本组84个根管完成治疗,成功率为82.4%,其中前牙钙化根管的治疗成功率为90.9%、前磨牙成功率为90.0%、磨牙成功率为73.5%;47.1%的根管单纯应用C型先锋锉即疏通成功,35.5%的根管需结合超声器械和根管显微镜疏通成功;均未发生根管侧穿或牙根折裂。结论:C型先锋锉结合超声器械和根管显微镜的使用,为处理钙化阻塞根管提供了行之有效的方法。
Objective: To investigate the clinical effect of C-avant-garde file combined with ultrasonic instruments and root canal microscope (DOM) on calcification obstruction root canal. Methods: 81 cases of calcified obstruction root canal patients with C-Pioneer file combined with special ultrasonic instruments and root canal microscope for root canal dredging, statistical treatment success rate. Results: The success rate of 84 root canal treatment was 82.4%. The success rate of calcification root canal treatment was 90.9%, the success rate of premolar teeth was 90.0%, molars teeth success rate was 73.5%, 47.1% roots The simple application of C-type avant-garde file that dredge success, 35.5% of the root canal to be combined with ultrasonic instruments and root canal microscope to clear success; no lateral root canal or root fracture. Conclusion: The use of C-Pioneer file combined with ultrasonic instruments and root canal microscope provides an effective method for the treatment of calcified obstruction root canal.
