Abstract
Taurodontism is a dental anomaly characterized by an enlarged pulp chamber and apically displaced pulpal floor. This disorder poses significant challenges in endodontic treatment, especially when perforations occur. The present case study details the endodontic retreatment of a hypertaurodont maxillary second molar in a 36-year-old female patient with a mesial canal perforation. The procedure employed a dental operating microscope for enhanced visualization and precision. Canals were prepared using a crown-down technique, with the perforation site managed using MTA and bioceramic material applied via the second mesiobuccal canal. The remaining canals were obturated using gutta-percha and bioceramic sealer. At the 1-year follow-up, the tooth was functional and asymptomatic, with radiographic evidence of a normal periodontal ligament space. This case demonstrates the efficacy of contemporary endodontic techniques, including bioceramic materials and advanced magnification, in managing the unique challenges posed by taurodontism.
