title: Endodontic retreatment of maxillary incisors previously treated with a conventional apexification protocol: a case report.
abstract: This case reports on the treatment of an immature tooth initially treated with calcium hydroxide apexification techniques. When the patient subsequently sought treatment for aesthetic concerns, the presence of apical periodontitis required revision of the endodontic procedure. Resolution of the periapical radiolucency was evident at a 12-month review. The use of mineral trioxide aggregate as an apical filling material and restoration with chemically cured composite resin extending into the coronal third of the root may prevent further contamination of the root canal system and strengthen the tooth.
