Platelet Rich Fibrin Aided Revascularization of an Immature, Non-Vital Permanent Incisor: A Case Report

Abstract: Traumatic dental injuries TDI in pediatric patients pose a significant challenge, often resulting in non-vital teeth with thin dentinal walls and open apices. Traditional treatment options, including single visit MTA apexification, may have limitations in promoting root growth and preventing fractures. This article presents a case report of an 11-year-old boy with a non-vital immature tooth treated with platelet-rich fibrin PRF as a scaffold material to induce revascularization, with 6 months follow up. This case report discusses the clinical and radiographical outcomes, demonstrating successful closure of the apex, thickening of root dentinal walls. PRF emerges as a promising biological approach for the revascularization of immature permanent teeth, although further histological studies are needed to confirm its mechanism.
