Platelet-rich fibrin and collagen matrix for the regeneration of infected necrotic immature teeth.

Unlabelled: Revitalization of an immature necrotic tooth is possible under conditions of total canal disinfection. This case report describes an immature tooth #21 with periapical pathology which was treated through revascularization using 3% sodium hypochlorite and 17% ethylenediaminetetraacetic acid as irrigants; calcium hydroxide was placed as an intracanal medicament, platelet-rich fibrin as a scaffold, and collagen matrix was placed as a barrier. On follow-up at 2 years, healing of periapical lesion, apical closure could be appreciated. Based on the results, we conclude that regeneration of necrotic tooth is possible under efficient disinfection.

Relevance For Patients: This article documents the 2-year outcome of regenerative endodontic treatment in necrotic immature teeth. The successful outcome of this case shows that regenerative endodontic teeth can be a viable treatment option in immature teeth.
