Taurodontism is a rare embryologic anomaly of teeth, defined by an apical displacement of the furcation of roots and enlarged pulp chambers. Taurodontism has been classified as hypo-, meso- or hypertaurodontism according to the severity of the anomaly. The aim of this case report was to illustrate a clinical case with multiple bilateral taurodonts and to describe the endodontic management of the hypertaurodontic mandibular left second molar with a C-shaped canal and extensive dental pulp calcifications. A healthy 20-year-old male patient was referred for the endodontic treatment of his lower left second molar. Cone beam computed tomography revealed a C-shaped root canal configuration and several dental pulp calcifications in this tooth. The endodontic treatment was performed in two appointments under an operating dental microscope. A panoramic radiograph, made during the 18 months follow-up appointment, revealed nine other taurodontic molars, most of them associated with dental pulp calcifications.
