Endodontic management of curved canals in mandibular molars- A case series

A tooth with a straight root canal and a single foramen is the exception rather than the rule. Most of the canals have multiple curvatures along their length, which poses difficulty in root canal instrumentation. Because of the presence of curved canals in mandibular molars, Endodontic treatment is very challenging. Curved canals have been found to be relatively higher in mandibular molars, ranging from 3.3 to 30.92% when compared to maxillary molars. Constricted canals and curvatures introduce factors that can increase the risk of procedural errors during root canal preparation. A thorough assessment of the preoperative radiographs, careful and a meticulous approach can yield into a safe and a successful endodontic treatment of such teeth. The current case series presents two such interesting cases of endodontic management of curved canals in mandibular molars.
