摘要
目的研究感染根管非手术性再治疗的可行性及可能存在问题和缺陷,寻找有效的针对性解决方案,进一步提高根管再治疗成功率。方法选择就诊需要再治疗189例患者,256颗患牙403根管为研究对象。结果遗漏根管及根管通路欠佳是根管再治疗的主要原因,根管数分别占31.27%和15.14%,以磨牙为主,占74.44%;其次是根管充填欠完善16.12%,C型根管10.17%,根尖疾病8.68%,冠渗漏3.23%,根管内器械分离2.73%。结论采取有效的解决方法后,对于感染根管行非手术性再治疗可明显提高患牙的治愈率、生存率,对提高诊治水平与医疗质量发挥重要作用。
Objective To study the feasibility of non - surgical root canal retreatment of infected root canals, and the possible problems and shortcomings. And to find the effective solutions, and further improve the success rate of root canal therapy. Methods In this study, 189 patients were collected and analyzed, 256 teeth with 403 root canals which needed to retreat in our hospi- tal. Results The missed root canals and the poor root canal pathway were the main reasons of the root canal retreatment （31.27% and 15.14% , respectively） ;16.12% was identified as the root canal with less perfect filling; 10.17% was accounted by C -type root canal and periapical diseases was 8.68% ;Coronal microleakage and instruments separation of root canal accounted for 3.23% and 2.73%. Conclusion Use the effective solutions, non - surgical root canal retreatment of infected root canals could help patients to improve the teeth with cure rate and survival rate significantly;Improve the diagnosis and treatment with oral clinicians, and also play an important role to promote the quality of medical care.
