Abstract

Dental avulsion of immature permanent teeth represents one of the most severe forms of traumatic dental injury, often complicated by external inflammatory root resorption (EIRR). This case report describes the management of an 11‑year‑old male patient who sustained avulsion of teeth 21 and 22 and subluxation of tooth 11. Following replantation, a rigid splint was initially placed but later replaced with a flexible splint in accordance with current IADT guidelines. At the three‑month follow‑up, radiographic examination revealed severe EIRR affecting teeth 21 and 22. Immediate endodontic intervention was initiated with repeated calcium hydroxide dressings over three months, followed by definitive obturation with mineral trioxide aggregate (MTA). Clinical and radiographic evaluations over a two‑year period demonstrated cessation of resorption, absence of symptoms, and continued root development of tooth 11. This case highlights the importance of early detection, timely endodontic therapy, and the use of biocompatible materials in the long‑term preservation of immature replanted teeth.
