Abstract :
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.
