Nonsurgical management of trauma-induced inflammatory internal- external root resorption: A case report

Root resorption is one of the serious consequences of dental trauma. If left untreated, it may lead to loss of significant portion of the root, rendering the tooth unsalvageable. This report documents the nonsurgical management of a previously traumatized maxillary lateral incisor (#22) with a large periapical lesion, severely affected by inflammatory communicating internal- external root resorption. A cone beam computed tomography was advised, to aid in diagnosis and treatment planning. Endodontic treatment comprised of copious irrigation with 1.5% sodium hypochlorite and 2% chlorhexidine gluconate, intracanal calcium hydroxide dressings and mineral trioxide aggregate (MTA) placement in apical 5mm.Follow up at 6 months showed arrest of resorptive process and initiation of periapical healing. At 12 months, complete radiographic healing in the absence of clinical signs and symtoms was evident.
