There have been many different devices and techniques developed to retrieve instruments fractured during endodontic procedures, but none of them can consistently remove separated instruments from root canals. Iatrogenic accidents such as perforation and canal destruction have been reported during the removal of separated instruments. The file removal process becomes even more difficult when breakage occurs in a curved canal or in the apical third of the canal.
