Novel management of avulsed tooth by pulpal and periodontal regeneration.
BACKGROUND
The avulsion of anterior teeth of young children is a tragic occurrence and often presents an unparalleled challenge for the dentist. Reimplantation is the state-of-the-art treatment but may incur several complications, particularly with inappropriate posttraumatic management.


METHODS
In this article we report the emergency and rehabilitation treatment of an avulsed maxillary anterior tooth by using platelet-rich fibrin. The osteoconductive and osteoinductive properties of platelet-rich fibrin were used to stimulate pulpal and periodontal regeneration.


RESULTS
During follow-up, no clinical signs and symptoms were present. After the initial 6 months, no further bone loss and attachment loss were observed. The tooth remained functional and was aesthetically acceptable.


CONCLUSIONS
When a tooth is avulsed, attachment damage and pulp necrosis occur. Viable periodontal ligament cells are often left on most of the root surface. If the periodontal ligament that is left attached to the root surface does not dry out, the consequences of tooth avulsion are usually minimal.
