Delayed Replantation of Avulsed Teeth: A Case Report

Abstract

Introduction: Dental avulsion is a severe injury in which the tooth is totally displaced out of its alveolar socket. Replantation of avulsed teeth is a standard procedure. The success of the treatment of traumatized teeth revolves around the status of periodontium since it is a vital structure. Furthermore, other factors, including extra-alveolar time period, choice of storage media, and contamination of the avulsed tooth, can determine the success of replantation. Delay in the replantation of avulsed incisors increases the risk of dentoalveolar ankylosis and replacement root resorption. Case Presentation: This case report presented a 9-year-old girl with tooth avulsion subjected to a 3-year follow-up after the replantation of avulsed maxillary central incisors kept in dry conditions for seven days. The avulsed mature permanent teeth were managed through the application of treatment guidelines with prolonged extra-oral time. The avulsed teeth were replanted and splinted for four weeks. The canals of both teeth were filled with calcium hydroxide and replaced by mineral trioxide aggregate after six months. Two months after replantation, there were signs of external root resorption in tooth 21. Conclusions: In the third year of follow-up, both teeth were infraoccluded, although they had an acceptable level of functionality and appearance. These ankylosed incisors can be managed successfully with the decoronation technique in the future.
