• Abstract: Endodontics focuses on the diagnosis and treatment of teeth with inflammation or necrosis of the pulp, including the use of endodontic files. However, fracture of files inside the canal is a reality in Dentistry. There are different treatment techniques for this problem: bypass technique , use of ultrasound, microtube systems and endodontic surgery. This literature review was based on scientific studies from the following databases: Google Scholar, PUBMED , LILACS and MEDLINE . Fifteen studies were selected from the search for the keywords bypass , endodontic surgery, file fracture, microscope, ultrasound, and the application of the inclusion and exclusion criteria. The bypass technique is the first option in cases of fracture in the apical third or beyond the curvature. The use of ultrasound is an alternative for removing fragments in straight canals, and can be associated with the optical microscope. Periodontal surgery is a more invasive procedure, useful in cases where other techniques have not been successful or in cases of fragments located beyond the apical foramen. Finally, microtubes also remove fragments in straight canals and can be associated with adhesive systems. It is concluded that each technique available will depend on the location of the fragment, the dental anatomy and the flexibility of the fractured instrument.
