  • Title: MTA for obturation of mandibular central incisors with open apices: case report.
    Author: Hayashi M, Shimizu A, Ebisu S.
    Journal: J Endod; 2004 Feb; 30(2):120-2. PubMed ID: 14977312.
    Abstract:
    The case reported demonstrates dramatic healing of the periapical region of retreated root canals with open apices by the successful use of mineral trioxide aggregate (MTA). Unsuccessful conventional root canal therapy for the mandibular central incisors had been followed by surgical treatment. The severely damaged root canals were obturated using MTA in anticipation of the formation of artificial apical plugs. The treated teeth were asymptomatic, and radiographic examination demonstrated apparent regeneration of periradicular tissue 2 years after the obturation. MTA can be considered a very effective material to promote regeneration of apical tissue, even in teeth with large open apices.
