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