For successful endodontic therapy, the clinician must have the thorough knowledge of root canal morphology. But variations in the root canal morphology makes the endodontic treatment challenging. One of the most challenging anatomic variations is the “C” shape configuration of the canal system. C shape canal presents an extensive complex system which is difficult to diagnose by preoperative Intra oral periapical radiograph as it is two- dimensional image of a tooth. However, with the help of Cone Beam Computed Tomography (CBCT) which is a non-invasive three-dimensional (3D) imaging technique, clinician will get more precise detailing of canal morphology which in turn helps in successful diagnosis and treatment of tooth which has “C” shaped canal morphology. Here, in this paper we are discussing a case of C shape canal in the mandibular third molar which was successfully diagnosed and treated with the help of CBCT.
