title: Obturation of immature non-vital tooth using MTA. Case report.
abstract: The purpose of this report was to present the treatment of an immature necrotic permanent mandibular second molar using mineral trioxide aggregate (MTA) as an orthograde root filling. In such cases, the canal remains large, with thin and fragile walls, and the apex architecture remains divergent. This case demonstrates the efficacy of MTA in this particular situation as an effective material to support regeneration of apical tissue in immature necrotic teeth. The treated tooth was asymptomatic. At the one-year follow-up, there were no clinical symptoms, but there was radiographic healing of periradicular tissues and new hard-tissue formation in the apical area of the affected tooth.
