“taurodontism” an Endodontic Enigma: a Case Report

The aim to publish this case report is to emphasize the clinical challenges involved in endodontic treatment of rare dental anomaly like Taurodontism. Endodontic management of a taurodont tooth has been described as complex and challenging. Present case is an attempt to emphasize the challenges an Endodontist encounters while treating Taurodontism affecting the molars of permanent dentition. An enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cementoenamel junction are the characteristic features. Negotiation of the orifices was extremely complicated owing to complex proximity and location of orifices. Low canal orifices and the potential for additional root canal system created difficulty in instrumentation and filling. Treatment required careful exploration of the grooves between all orifices under operating microscope. Canal cleaning and shaping was performed using Protaper rotary instruments and 2.5% sodium hypochlorite ultrasonic irrigation and obturated using a modified filling technique.
