Taurodontism: An anatomical challenge to clinical endodontics

Abstract

While considering the various developmental anomalies of tooth, taurodontism is one of the morpho-anatomical anomalies which is rarely seen. The lack of constriction at the level of cemento-enamel junction with elongated pulp chambers and apical shift of bifurcation or trifurcation of roots, gives the tooth a rectangular or cylindrical appearance. The root canal system complexity, changed configuration and sometimes, the presence of additional root canals offer a big clinical challenge while performing the endodontic therapy. Till date, most of dental practitioners are having little awareness about such condition and its endodontic management. Therefore, this paper reviews about the details of taurodontism including its etiology, pathogenesis, diagnosis, types, categorization and difficulties produced during endodontic management along with their solutions.
