Abstract

This article reports a clinical case of an 8-year-old boy who sustained avulsion of the maxillary right central incisor and the maxillary left lateral incisor. The avulsed teeth were kept in adverse extraoral dry conditions for 1 h from the moment of trauma until their replantation. The prognosis of tooth replantation is dependent on multiple factors such as methods of teeth storage in vitro, endodontic intervention, extra-oral time, and type of retention employed. The main reasons for root resorption in this case may be the extra-oral time, the initial replantation, or the delayed endodontic treatment.

Keywords: Dental avulsion; Dental trauma prognosis; Replantation; Root resorption; Treatment.
