目的评价根管显微镜联合超声器械处理困难根管的临床疗效。方法对208个常规治疗无法处理的困难根管,包括钙化不通、器械折断、侧穿底穿,采用根管显微镜配合超声器械处理并统计成功率。结果钙化不通根管、器械折断根管、侧穿底穿根管的治疗成功率分别为77.01%、75.26%、70.83%,总体成功率为75.48%。结论根管显微镜联合超声技术可以使许多困难根管得到完善治疗。
Objective To evaluate the clinical efficacy of root canal microscopy combined with ultrasound in the treatment of difficult root canal. Methods 208 cases of difficult root canal treatment which could not be treated by routine treatment included calcification, device breakage, side wear, and endoscopic wear and tear with endoscopic microscope and ultrasonic instrument, and the success rate was calculated. Results The success rate of calcification unreasonable root canal, instrument broken root canal and lateral perforating canal was 77.01%, 75.26% and 70.83%, respectively. The overall success rate was 75.48%. Conclusion Root canal microscope combined with ultrasound can make many difficult root canal treatment.
