title: Nonsurgical endodontic retreatment.
abstract: The purpose of this clinical article is to emphasize that although there is enormous potential for endodontic success, clinicians are, at times, confronted with post-treatment disease. A rationale for endodontic treatment is followed by the goals of nonsurgical retreatment. The focus of this article is to identify the various nonsurgical retreatment categories and provide an overview of the concepts, armamentarium and techniques available to disassemble roots, address deficiencies or repair defects that are pathological or iatrogenic in origin.
