Management of A Case of Trauma Induced Inflammatory External Root Resorption

Inflammatory root resorption is a pathologic condition caused by several etiologic factors including traumatic dental injury. In this case report, we describe the treatment of a maxillary central incisor affected by severe perforating inflammatory root resorption communicating with canal in the middle 3rd of buccal surface of root along with bone loss. Treatment involved elevating the buccal flap, placing master apical file in the canal and applying a layer of glass ionomer cement (GIC) on the resorbed surface. Thick layer of mineral trioxide aggregate (MTA) was mixed and applied over the GIC layer and the flap was repositioned and sutured. The calcium hydroxide iodoform dressing was kept in the canal for six months and evaluated. The endodontic access cavity was restored with GIC. After a year, advanced osseous healing of the periradicular region had occurred and no clinical symptoms were apparent.
