Teeth with incomplete root development have short roots with thin walls, which compromises their longevity. Through regenerative therapy, we can facilitate root development in previously immature teeth with necrotic pulps. This is a significant benefit over conventional root canal treatment and especially valuable for young patients, as teeth preservation is critical to their skeletal and dental development. Regenerative therapy may be considered because the stem cells present inside the canal and Apical papilla stem cells may help in the closure of the open apex by differentiating into cells required for root formation.This case report describes a 14-year-old female patient with an immature non-vital Right Maxillary Central Incisor with a grade I mobility and apical pathology, which was treated via revascularization using 1.5% NaOCl and 17% ethylene diamine tetraacetic acid as irrigants; triple antibiotic paste as intracanal medicament and platelet‑rich fibrin (PRF) as the scaffold. After 3-months, the clinical examination revealed a reduction in mobility to physiologic level, negative responses to percussion, and palpation tests. 6-month, 1-year, and 1.5-year radiographic examination revealed regression of the periapical lesion and increased root wall thickness.Based on the follow-up of this case report, it can be concluded that regenerative endodontic therapy using PRF can be a viable treatment option for necrotic infected immature teeth.
