Treatment of complex dentoalveolar injury--avulsion and loss of periodontal tissue: a case report.

Dental avulsion is a common and complex injury which affects multiple oral tissues. In this case report, a 9-year-old girl patient with two traumatically avulsed maxillary central incisors with loss of periodontal tissue was presented. Treatment guidelines for avulsed permanent teeth with open apex were carried out. Bilateral laterally sliding flap procedure was performed, to repair loss of gingival soft tissue. Conventional immobilization was carried out for 6 weeks. Five months follow-up of the patient in whom replantation was performed resulted in positive sensitivity test, no symptoms of infection, pain or any discomfort and good periodontal wound healing. In conclusion, this report presents successful replantation and periodontal treatment of a patient with complex dentoalveolar injury.
