Abstract
Avulsion injuries are a severe type of dental trauma that can result in sequelae such as root resorption, ankylosis and tooth loss. We report on an unusual case where a previously avulsed, replanted and root-treated UR1 did not erupt for 3 years, and then spontaneously erupted. Findings from a small volume CBCT scan showed significant internal root resorption extending to the root wall, which supports an explanation of the internal root resorption removing an area of ankylosis and allowing the tooth to erupt. The value of using dental CBCT scanning is highlighted in managing complex dental trauma. CPD/Clinical Relevance: The use of a small volume CBCT scan can give insight into the clinical presentation of post-traumatic tooth movement.
