Abstract

  Endodontic procedures include partial and total pulpotomy, pulpectomy, apexification, and apexogenesis. Failures of endodontic treatment implicate bacterial infection. Regenerative endodontic therapies involve pulp floor and root perforations. Failures occurr after the disinfection and removal of necrotic tissues. Three possible mechanisms include perforations that arise primarily through: 1) procedural errors occurring during root canal treatment, 2) post-space preparation, and 3) resorptive processes. Inadequacy of endodontic treatments involve mostly bacterial infection (or re-contamination). In addition, bur perforation during access opening during the search for canal orifices, excessive removal of dentin, either with hand or rotary instruments, and/or unsuccessful attempts at bypassing separated instruments. Root canal perforations may also result from excessive removal of tooth structure. This is occurring in anatomically vulnerable locations such as the mesial roots of lower molars. Classification of perforation divides the root into the coronal, crestal, and apical portions. They are implicated in root perforation and/or bacterial re-infections. Transportation, ledge and zipped are also important factors implicated in endodontic failures.
