Endodontic Management of C-shaped Root Canal Configuration using Different Obturation Systems: Case Series

C-shaped canal is one of the most difficult situations with which the dentist is confronted during endodontic treatment of teeth. Recognition of unusual variation in the canal configuration is critical because it has been established that the root with a single tapering canal and apical foramen is the exception rather than rule. The early recognition of these configurations facilitates cleaning, shaping and obturation of the root canal system. “C” configuration, which is an important anatomic variation, presents a thin fin connecting the root canals. The present case series reports the successful management of C-shaped canals in mandibular second molars using cone-beam computed tomography(CBCT), sonic irrigation activation and different thermoplasticized gutta percha obturating techniques.
