Instrument fracture during endodontic therapy is an undesirable complication, which can lead to treatment failure. When this happens, it requires further planning of the case, aiming at a change of conduct in order to remove or surpass the instrument. It is important at this time the professional’s knowledge of numerous techniques and mastery of instruments to execute them. In this study, a literature review was carried out in which it was concluded that the removal of fractured instruments in straight root canals is more easily solved than in curved root canals, that the use of ultrasonics associated with the operating microscope significantly increases the success of the removal, and if the fractured instrument removal from the canal is not possible, the overpass of the fragment has the best prognosis for the treatment.
