Endodontic Management Of C-shaped Root Canal Followed By a Post Less Core and Crown-a Case Report

Abstract

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. In this case report we have discussed the successful management of C-shaped canal (Melton’s category II) in mandibular second molar diagnosed by using cone-beam computed tomography and operating microscope and also used self-adjusting file (SAF), sonic irrigation and thermoplasticized gutta percha obturating technique. Endocrown-type restorations are single prostheses fabricated from reinforced ceramics that can be acid etched, indicated for endodontically treated molar teeth that have significant loss of coronal structure. Endocrowns are formed from a monoblock containing the coronal portion integrated into the apical projection that fills the pulp chamber space, and possibly the root canal entrances. A endocrown-type restoration was fabricated from lithium disilicate ceramic (IPS e.Max) in a mandibular second molar with extensive lingual destruction.
