The purpose of this report is to present the treatment of 2 immature necrotic permanent incisors with the use of apical plugs of mineral trioxide aggregate (MTA) for apexification. With this technique, MTA mixture is used to create an artificial stop against which to condense gutta-percha in pulpless teeth with open apices. The report of these cases confirms that MTA acts an apical barrier and can be considered as an effective material to support regeneration of apical tissue in immature necrotic teeth. The treated teeth were asymptomatic, and radiographic follow-ups showed healing of periradicular tissues and new hard tissue formation in the apical area of the affected teeth.
