Abstract
OBJECTIVES
To evaluate the clinical application of the dental operating microscope (DOM) in the management of complicated root canal therapy.
METHODS
345 teeth with 546 root canals which could not be successfully managed by conventional methods received therapy under the DOM with ultrasonic instruments by the same endodontists. The aetiology of the canals included calcification, broken instrument, missed canal and canal perforation. The teeth and canals successfully managed were then calculated.
RESULTS
406 canals were successfully managed with a rate of 74.4%; 246 teeth were successfully managed with a rate of 71.3%. The rates in each category of the complicated root canals were: 74.0% for calcified canals, 72.3% for canals blocked by broken instruments, 82.5% for missed canals and 72.7% for canal perforations.
CONCLUSIONS
The clinical application of the DOM is an effective way of managing complicated root canal therapy.
摘要
目的
评估口腔手术显微镜（DOM）在复杂根管治疗中的临床应用。
方法
345 颗牙齿的 546 个根管经传统方法治疗失败，由同一位牙髓病医生采用超声器械在 DOM 下进行治疗。这些根管的病因包括钙化、器械折断、遗漏根管和根管穿孔。计算成功治疗的牙齿和根管数量。
结果
406 个根管成功治疗，成功率为 74.4%；246 颗牙齿成功治疗，成功率为 71.3%。各类型复杂根管的成功率为：钙化根管 74.0%，器械折断阻塞根管 72.3%，遗漏根管 82.5%，根管穿孔 72.7%。
结论
DOM 的临床应用是处理复杂根管治疗的有效方法。
