Nonsurgical retreatment and reinforcement of an immature permanent tooth with periapical lesion of endodontic origin

Endodontic management of immature traumatized teeth usually involves carrying out conventional (apexogenesis and apexification) or regenerative endodontic treatment. While continued development of the radicular tooth structure should be the desired outcome of treating teeth with open apex, in cases of necrotic teeth or retreatment procedures, the formation of apical barrier via apexification is a more feasible approach. A 21-year-old boy reported with a traumatized maxillary central incisor with incomplete root development, previously treated 13 years ago; it was decided to retreat the tooth endodontically and carry out rehabilitation via reinforcement of the root using fiber post. The post was customized by relining it with direct, visible-light-cured composite resin and final cementation was carried out using dual cure composite resin. This paper aims to present and discuss different treatment modalities possible in a young traumatized tooth.
