摘 要:目的:寻求高效去除牙胶及根充糊剂的临床方法。方法:选取168个曾行牙胶充填需根管再治疗的根管,使用Desocclusol(商品名汀克除)结合手工机械法去除根管内充填物和根管再通预备,采用冷牙胶侧向加压法充填根管,评价其临床疗效。结果:原根充物全部清除,有效防止了治疗过程中台阶形成、根管侧穿或器械折断等并发症发生,再治疗成功率达89.3%。结论:使用汀克除结合手工机械法有助于提高根管再通,省时省力,是一种能减轻医师工作强度、提高工作效率的方法,值得临床推广使用。PURPOSE:To investigate the clinical method to remove a gutta-percha and root canal sealers.METHODS: 168 root canals which had been filled with gutta-percha were selected,all root canals needed endodontic retreatment.The root canal fillings were removed and the root canal was re-prepared with the method of desocclusol and manual mechanical method.Then the root canal was filled again with lateral condensation technique.RESULTS: With manual mechanical method and desocclusol,all original root canal fillings were removed completely.The combined method could effectively prevent the formation of step,root canal-side wear,broken equipment or other complications during the course of retreatment.The success rate of retreatment was 89.3%.CONCLUSIONS: Combined manual mechanical method with desocclusol could improve the success rate of recanalization of the root canal and saved time and effort.It is a method which could reduce the intensity and improve the efficiency of dentists,and worthy of wide clinical application.Supported by Research Fund of Department of Health of Jiangxi Province(20063127)and Jiangxi Provincial Department of Science and Technology(2008BB2860).
