Factors influencing ledge formation and its management in endodontics

Abstract

Endodontic treatment can be predictable, successful, and relatively easy to perform if every individual step is performed appropriately. Hasty mechanical and chemical manipulation of the root canal system can lead to procedural error. Procedural accidents during endodontic treatment occurs either due to inadequate attention to the details. Removal of canal wall structure on the outside curve in the apical half of the canal due to the tendency of files to restore themselves to their original linear shape during canal preparation may lead to ledge formation and possible perforation.
