Regenerative endodontics is now an established treatment modality for necrotic immature permanent teeth. This case report describes the treatment of a necrotic immature permanent maxillary central incisor with crown fracture using a regenerative approach instead of the conventional apexification procedure. The necrotic root canal was gently debrided, irrigated and then medicated with triple antibiotic paste. At 1-month recall appointment, the tooth was asymptomatic. Bleeding was induced by filing the canal beyond the apex and collagen was placed along with induced blood clot. After 12 months follow-up, healing of periapical lesion, progressive thickening of the root canal walls, and apical closure was radiographically evident. This suggests that regenerative endodontic treatment is an appropriate treatment modality for the management of necrotic immature permanent teeth. Collagen scaffold combined with bleeding induction results in apical closure in immature teeth.
