Inflammatory root resorption is a pathologic condition caused by several etiologic factors including traumatic dental injury. In this case report, we describe treatment of a maxillary lateral incisor affected by severe, perforating inflammatory root resorption. An 11-year-old patient presented with a previously traumatized, root-filled maxillary lateral incisor associated with pain, mobility and a sinus tract. Radiographic examination revealed a large periradicular lesion involving pathologic resorption of the apical region of the root. After removal of the root canal filling, the tooth was treated with intracanal calcium hydroxide for 2 weeks. The calcium hydroxide dressing was then removed and the entire root canal was filled with mineral trioxide aggregate. The endodontic access cavity was restored with composite resin. After 1 year, advanced osseous healing of the periradicular region had occurred and no clinical symptoms were apparent.
