The undesirable outcomes of late-referral traumatized immature permanent teeth and root-end-closure with mineral trioxide aggregate apical plug technique

Abstract

Dental traumatic injuries mostly occur in children and affect the anterior dental region. The immediate management of the injuries prevents the loss of dental and alveolar structures. The lack of natural apical constriction in immature permanent teeth due to the pulp necrosis is problematic to treat. Frequently, the apical plug technique is used to attain apical closure that provides the obturation of the root canals without extrusion of the obturation material. In this case report, the endodontic treatment was achieved using apical plug technique with mineral trioxide aggregate (MTA) while prosthetic crown retained with fiber-reinforced post was used to restore the traumatized crown fracture of maxillary incisors. This case report suggests that MTA is influential apical barrier and successively induce periapical healing. Clinical Relevance to Interdisciplinary Dentistry This article is the case report of a young 17-year-old boy with immature permanent teeth and crown fracture The treatment of necrotic traumatized permanent teeth using mineral trioxide aggregate apical plug technique on a short-time scale is successful to achieve apical seal and healing of apical periodontitis while motivating the patient to attend the treatment The crown fracture requires the use of fiber post that is suitable material for immature permanent root canals.
