Objectives: The purpose of the study was to examine efficacy of this procedure in necrotic immature permanent teeth. 

Methods: Forty patients were enrolled for pulp revascularization procedure by disinfecting the root canal with triple antibiotics paste for one to two weeks, followed by creating the blood clot, sealing the canal orifice with mineral trioxide aggregate as sealing material. Patients were recalled periodically for up to twenty four months.

Results: Clinical evaluations demonstrated no adverse effects, during follow up 35 patients were asymptomatic, five cases of periapical periodontitis showed disappearance of sinus tract, on radiographic assessment there was progressive resolution of periapical radiolucency within first three-six months, the electric pulp test on sixth week demonstrated positive response, on radiographic evaluation there was progressive root length and thickness and continued root growth on six –twelfth months.

Conclusion: Revascularization is a safe and efficacious method of dental pulp regeneration in this study.
