Radicectomy of radix entomolaris: An alternative treatment approach for persistent periapical lesion assisted by cone-beam computed tomography and operating microscope

Every clinician as well as patient would prefer to sustain their natural teeth in all situations. For a badly mutilated terminal abutment, molar treatment options are limited, but loss of posterior tooth can lead to several unwanted sequelae. A guiding principle should be to preserve what is present. If complete preservation is not possible, the most conservative treatment should follow in every clinical situation. Radisectomy is one such conservative surgical treatment approach that allows resection of one or more affected roots of tooth at the level of furcation and preserves the remaining roots and the complete crown structure, thereby maintaining the occlusal harmony. Hereby, we are presenting a case report on radicectomy of distobuccal root of a mandibular third molar with persistent periradicular pathosis, with the assistance of microscope and cone-beam computed tomography.
