C.E. Credit. Management of Severe Intrusive Injury in an Immature Permanent Incisor with Revascularization

Abstract

ABSTRACTBackground Traumatic intrusion is considered one of the most severe dentoalveolar injuries; however, there is limited research detailing the management and treatment of these injuries, particularly in immature permanent teeth.Case Description This case report describes the management of a severe traumatic intrusion presenting with an uncomplicated crown fracture, pulp necrosis and external root resorption in a 7-year-old African American female. The left maxillary central incisor (tooth No. 9) was intruded approximately 10 mm and inaccessible. The tooth was orthodontically extruded over the course of five months. Once exposed, a regenerative endodontic procedure under oral sedation was completed. Clinical and radiographic examinations during the follow-up period showed cessation of the resorption process and discontinuation of signs and symptoms.Practical Implications This case demonstrates that severe intrusive injuries in immature permanent teeth can be effectively managed with revascularization even when initiation of revascularization must be delayed due to extended time needed for orthodontic repositioning.Continuing Education Credit Available: The practice worksheet is available as supplemental material for this article: https://doi.org/10.1080/19424396.2023.2176580.A CDA Continuing Education quiz is online for this article: https://www.cdapresents360.com/learn/catalog/view/20
