摘要:
牙髓病和根尖周病主要是细菌感染性疾病,根管治疗术则是国际上公认的最有效的治疗方法。随着口腔新技术、新材料的研发和应用,其成功率也在不断提高。但由于根尖周感染状况不同、根管系统和髓腔的解剖结构的复杂性和多样性、微生物变种及毒力改变、医疗器械或医生临床技能的差异等因素,仍有一些病例治疗效果不佳或者治疗失败,需要进行根管再治疗。文章旨在通过分析初次根管治疗失败的原因,对根管再治疗的诊治策略做一介绍。

Abstract:
Pulpitis and apical periodontitis are mostly casued by microbial infection. The most effective method internationally recognized is root canal therapy. With the development and application of new technology and material,the success rate is increasing. However,because of the infection variety,anatomic complexity of root canal,the variety of the microbe and toxicity,and the limitation of current technology or the clinicians′skills,the unsatisfactory result and failure in treatment still exist. Endodontic retreament is an effective way to solve the problem. The paper aims to introduce the diagnosis and management strategy of endodotic retreament by analyzing the reason for failure of previous root canal therapy.
Key words: endodontic retreament, mechanochemical preparation, microapical surgery, intentional replantation, single tooth implant
