Solution methods of instrumentation related complications in endodontic treatment

Background: Endodontics is a skill that requires the use of precision instruments in tight spaces and is a complex discipline often underestimated by clinicians and patients. Inevitably, this will lead to complications. Complications encountered during endodontic treatment occur during diagnosis, anesthesia, cleaning, and shaping of the root canals and filling the root canals. Complications can occur at any stage of treatment. The various procedures associated with root canal treatment can be divided into three treatment phases: Pre-operative, operative, and post-operative. Since endodontic complications may occur at any of the pre-operative, intraoperative, and post-operative stages, complications that may develop are also classified in the same way. Aim: In this review, operative complications including instrument fracture, ledge formation, canal obstruction, apical transportation, and strip perforation that may occur during canal preparation in endodontic treatment are discussed. Conclusion: Technological developments in endodontics have revealed methods and instruments enable successful treatment of calcified root canals, severe canal curvatures, ledges, resorption defects, perforations, and broken canal instruments without complications. Clinical Significance: Therefore, the physician should always be ready to manage complications. The task of the physician is to know how to avoid potential complications and how to manage complications that may arise during treatment
