Abstract
Aim: To report the diagnosis and management of a case series of C shaped canals in mandibular second molars. Summary: A thorough knowledge of the root canal morphology is required for successful endodontic therapy. Coupled with information gleaned from preoperative dental radiography, the clinician can assess to a great extent the anatomic challenges in each tooth. Although not all-encompassing, preoperative radiographs might aid in visualizing and observing the main anatomy of various root canal systems. One of the most important anatomic variations is the “C” shape configuration of the canal system. C shape canal presents an extensive complex system and is mostly seen in mandibular second molars. Careful assessment of preoperative radiograph is a key step for its subsequent management, and this assessment might impact greatly on the treatment outcomes. The main anatomic feature of this is the presence of fins or webs connecting individual mesial and distal canals. The C-shape configuration presents a challenge to debridement and obturation. This paper reports four cases of ‘C’ shaped canal in the mandibular second molar which were diagnosed and managed successfully. Key Learning Points : ‘C’ shape canals in mandibular second molars are found more in Asians than in cancasuions.They can be successfully diagnosed and treated by careful endodontic instrumentation.
