Abstract
Endodontic treatment of immature necrotic permanent teeth is clinically challenging and poses a risk of inducing dentin wall fracture or extending gutta-percha into the periapical tissue during root canal filling. Pulp revascularization is a promising alternative for the treatment of such immature necrotic permanent teeth offering great potential to avoid the need for traditional apexification with calcium hydroxide or the need to achieve an artificial apical barrier with mineral trioxide aggregate. Pulp revascularization allows the stimulation of the apical development and the root maturation of immature teeth by physiologically strengthening the canal walls. The present case report describes the case of successful revascularization of the necrotic infected pulp space of an immature permanent maxillary central incisor induced in vivo by stimulation of a blood clot from the periapical tissues into the canal space. Thickening of the canal wall and complete apical closure were confirmed 15 months after the treatment.
