Necrotic immature teeth present a challenge to dentists because the techniques used in apexification leave the tooth susceptible to fracture, since the root does not continue to grow in length and the canal walls are thin. Revascularization has emerged as an alternative to resolve these deficiencies, enabling apical closure, continued development of the roots, and thickening of the dentinal walls. Case report: clinically and radiographically diagnosed necrotic immature permanent tooth was treated via revascularization treatment. The therapeutic protocol involved accessing the pulp chamber; irrigating copiously with saline; applying a double antibiotic paste as intracanal dressing; then provisionally sealing it. After 3 weeks, the canal was cleaned and the apex irritated with a size 15 K-file to induce blood that would serve as a scaffold for pulp revascularization. MTA was used as a coronal plug. Follow up of 3, 6 and 9 months presented.
