Dry extraoral storage and delayed replantation of avulsed tooth: Therapy and outcome

Introduction: The aim of this study was to present the therapeutic procedure and the outcome of replantation of the avulsed permanent central maxillary incisor, found at the site of high contamination, after an extraoral period of 15 hours and dry transport. Case report: By clinical examination it was determined that the root reached the full length, with parallel edges, which corresponded to the age of the girl-8.5 years. After carefully removing the necrotic periodontal ligament from the root of the tooth, extraoral endodontic treatment was performed. The pulp was removed, the multi-sessional intracanal medicament fillings were avoided and the definitive obturation of the root canal was performed. The tooth was returned to the alveolar socket and immobilized with a wire-composite splint. After replantation, the condition of the tooth was monitored. Replacement resorption and dentoalveolar ankylosis occurred after nine months, and then cervical inflammatory resorption led to tooth loss after three and a half years. Conclusion: The achieved result can be considered as a success because during this time the replanted tooth met the developmental, functional and aesthetic requirements, which is especially important in the period of intensive growth and development of the child.
