Introduction: Taurodontism is a morpho-anatomic variation in tooth anatomy that rarely affects mandibular premolars. Literature is replete with mandibular first premolars presenting atypical additional root canals, but concurrent presence of three roots and taurodontism is exceptional.
Materials and methods: This case report describes the successful endodontic diagnosis and management of a rare case of taurodontism in a mandibular first premolar with chronic apical periodontitis. Cone beam computed tomography (CBCT) facilitated the diagnosis of three roots and root canals associated with concurrent taurodontism. The taurodont premolar required exceptional and diligent care in each segment of endodontic treatment for the complex root canal system.
Results: Taurodontism-affected premolars present with challenges in endodontic therapy as they have apically displaced pulp chambers with limited width. Cone beam computed tomography and dental operating microscope can facilitate evaluation for teeth with such complex anatomy and their successful endodontic management.
