Immature permanent teeth damaged by caries or trauma can present a challenge to dentistry. Currently, triple antibiotic paste (TAP) containing ciprofloxacin, metronidazole, and minocycline is used to attempt revascularization in necrotic immature teeth. Therefore, the purpose of this report was to present a case of pulp revascularization in an immature necrotic tooth. An 8-year-old male presented with trauma to the permanent maxillary left and right central incisors. Upon clinical and radiographic examination, the left central incisor was deemed necrotic. Revascularization therapy was performed over multiple visits. At 11 months follow-up, healing of the periapical area and apexogenesis were found to be complete. With an increasing breadth of clinical evidence and practitioner acceptance, regenerative techniques may become a standard technique in treating immature necrotic permanent teeth.
