Mishaps and serious complications in endodontic obturation

There are numerous examples reported in the literature that cite and document many disabling complications to the alveolar bone, neurovascular anatomy and maxillary sinus following overextension of root canal filling materials. Neural complications as a consequences of endodontic obturation as well as other server outcomes to overfill are a serious problem. These injuries require a thoughful strategy for prevention during endodontic procedures as well as a responsible systematic approach to management, should the outcome of endodontic therapy produce an injury. This monogrph will focus on measures that can prevent obturation mishaps which occur under the most vulnerable of circumstances during the course of endodontic therapy. This paper will also critically review the toxicity of materials used in endodontic obturation and seek to identify those principal factors which affect prognosis after injury.
