Challenges in endodontic management of taurodontism

Taurodontism is the dental anomaly caused by the failure of Hertwig’s epithelial sheath diaphragm to invaginate at the proper horizontal level. The characteristic features are, enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cemento-enamel junction. Both the permanent and deciduous dentition presents taurodontism, unilaterally or bilaterally, and in any combination of teeth or quadrants. Permanent molar teeth are most commonly affected. The complexity of the root canal is the challenging task while performing endodontic treatment on such teeth. Careful diagnosis and investigation with the three dimensional imaging technique like computed tomography, use of surgical microscope and ultrasonic irrigation and thermoplasticised obturation technique helps in success of endodontic treatment with taurodontism.
