The present case report aims to address a treatment option for a previous tooth with incomplete rhizogenesis after dental trauma and subsequent aesthetic rehabilitation. The patient attended the service, reporting trauma to the anterior teeth about 10 years ago, with a consequent fracture in the left upper central incisor, in which only the restorative procedure was performed. Years later, he presented facial edema and was submitted to an urgent care, without endodontic treatment. In the present periapical radiographic examination, a radiolucent area was observed in the apical region, broad root canal, open pulp chamber, and with a temporary sealing. Still, the observed image suggested that the tooth presented incomplete rhizogenesis. As a treatment plan, we chose endodontic therapy and apical closure with mineral trioxide aggregate  (MTA) for posterior aesthetic rehabilitation with external and internal dental whitening, restorative procedure with fiberglass pin and coronary reconstruction with composite resin. Considering the clinical and radiographic findings observed after three months of proservation of the case, satisfactory results were obtained, which demonstrates that the therapeutic approach used is presented as an effective treatment option for necrotic traumatized teeth with incomplete rhizogenesis associated with periapical lesions.
