Aim: To demonstrate an exceptional result in the treatment of an avulsed tooth that had been stored in a dry environment for over 2 hours before being replanted. Background: Sixteen percent of all traumatic injuries to the permanent dentition are avulsions. Maxillary central and lateral incisors are most commonly affected. Case description: In this report, a 7-year-old girl sustained trauma to the upper right maxillary incisor during a bicycle accident. The tooth was avulsed and remained outside the oral cavity for more than 2 hours in a dry napkin before eventual reimplantation in the emergency room. Upon presentation to the endodontic clinic at the University of Southern California, the case was assessed, and the available treatment options discussed with the patient's parents. Revascularization using BC putty was the chosen mode of treatment. At a 6-month recall appointment, the patient presented with a sinus tract. A decision was then made to perform apexification using the mineral trioxide aggregate (MTA) as an apical filling material. To date, the tooth remains intact and functional. Conclusion: Although both of the described treatment modalities are acceptable and commonly used in modern endodontics, apexification of a tooth following a failed attempt of a regenerative procedure has not been described. In this case, a chronic abscess formed and the ultimate goal of revascularization was not achieved. However, the performance of the revascularization procedure was not without benefit since it allowed the tooth to develop in both length, dentinal volume, and aided in the partial closure of the apical foramen. Additional studies are needed regarding the treatment of avulsed teeth. This case study may provide a viable treatment alternative in a number of clinical situations. Clinical significance: The procedures described in this case report may be of clinical significance in the treatment and retention of teeth, which may otherwise be considered to have a poor prognosis and extracted.
