摘要
Regenerative endodontic procedures are undertaken on permanent teeth with necrotic pulps and open apices in an attempt to resolve symptoms, to allow the continued development of the root(s), and to reestablish vitality. The available histologic analysis of these teeth has, in the majority of studies, shown that true regeneration of the pulp-dentin complex is not achieved. A recent investigation using an animal model outlined a procedure wherein pulpal amputation a few millimeters short of the apex followed by evoked bleeding allowed the complete regeneration of the normal pulp-dentin complex in immature vital teeth of ferrets. By implementation of this procedure, we report successful pulp regeneration outcome evidenced by continued root development and a positive response to pulp vitality tests in a maxillary central incisor with an open apex diagnosed with symptomatic irreversible pulpitis.
