This article elucidates the utilization of a novel platelet concentrate-concentrated growth factor (CGF) for rapid and successful healing outcome in regenerative endodontics. This case report focusses on two cases: 23-year-old and 21-year-old patients with incomplete root formation and periapical lesion. Case 1 and case 2 are classified as stage IV and stage II, respectively, in accordance with Cvek's classification of open apex and had varied outcomes. The extent of open apex, root dentin thickness, and lesion were assessed using periapical radiograph and CBCT. Revascularization procedure was carried out after obtaining patient consent. Following bleeding induction, CGF was prepared, placed, and condensed using pluggers in the root canal space, followed by the placement of mineral trioxide aggregate (MTA) up to the level of CEJ. At 1-year follow-up, apical closure with increased root dentin thickness and reduced periapical radiolucency was evident.
