Abstract
Avulsion injuries are usually seen in the anterior maxillary teeth as a result of trauma. Avulsion as an endodontic mishap is extremely rare. This report highlights an unusual instance of exarticulation of a recently traumatised maxillary central incisor tooth when the rubber dam was applied during a routine non-surgical endodontic procedure. The tooth was immediately repositioned and stabilised with wire composite splint. Endodontic treatment was initiated after rubber dam isolation with a modified technique. Calcium hydroxide was used as intracanal medicament dressing, and obturation was done after 2 weeks. The treatment was successful with uneventful periodontal healing at 24-month follow-up. The presence of well-demarcated periodontal ligament space and absence of any resorptive area on the radiograph could be defined as a successful outcome for the present case.
