摘　　要：目的:评价热牙胶用于后牙器械分离根管行旁路根管充填的效果。方法:选取27例27颗出现根管内器械分离未能取出的患牙,从分离器械旁建立通路并采用热牙胶连续波充填技术对根管进行旁路充填,X线观察根管充填情况,追踪随防2年,通过临床及X线片检查评价其疗效。结果:2年后接受回访24例,根据根管治疗疗效评价标准,治疗成功19颗牙,治疗成功率79.2%。5颗治疗失败的患牙中4颗治疗前患根尖炎,1颗为牙髓炎。结论:当器械分离在根管内不能取出时,在分离器械旁建立通路并采用热牙胶连续波充填技术进行旁路根管充填是一种行之有效的治疗方法。Objective:To study and evaluate the clinical effect of warm gutta on the root canal therapy bypassing intracanal separated instruments.Method:27 teeth which selected from 27 patients were the intracanal separated instuments couldn't be taken out,preparated the root canal and adopted continuous wave of condensation technique to obturation the root canal bypassing broken instruments.Taking X-ray to study the root canal filling,close obseration for two years and through clinical examination and X-ray to evaluat the efficacy.Result:After two years,24 patients were followed up and there are 19 teeth were sussessfully treated.according to the evaluation criteria of root canal therapy,successful rate was 79.2 %.4 teeth of the failed cases were suffering from apical infammation before trearment,1 teeth was pulpitis.Conclusion:When the instrument separated in the root canal and couldn't be taken out,building the bypass root canal next to the separated instrument and taking the continuous wave of condensation technique to fill the root canal bypassing broken instruments is a feasible and effective method.
