With all the potential for endodontic success, the fact remains clinicians are confronted with posttreatment endodontic disease. When the elected treatment plan is endodontic nonsurgical retreatment, then the goal is to access the pulp chamber and remove materials from the root canal space and if present, address deficiencies or repair defects that are pathologic or iatrogenic in origin. This article provides a literature review with clinical recommendations for one important group of retreatment issues: the removal of posts and broken instruments.
尽管牙髓治疗有取得成功的种种可能性，但临床医生仍面临牙髓治疗后疾病的问题。当选择的治疗方案是牙髓非手术再治疗时，目标是进入髓腔并从根管空间清除材料，如有需要，处理源于病理或医源性的根管壁缺损或修复缺陷。本文针对再治疗的一个重要问题组——桩的取出和折断器械的取出——进行文献综述并给出临床建议。
