Clinical Success of MTA Apical Barrier in a Tooth with Open Apex: Two Case Reports and Literature Perspective

Open apices in non-vital immature teeth present a significant endodontic challenge. The lack of apical constriction compromises the ability to establish an effective apical seal, complicating obturation and increasing the risk of periapical pathology. Various techniques have evolved, including apexification using calcium hydroxide, and the use of biocompatible materials such as mineral trioxide aggregate (MTA) and Biodentine for apical barrier formation. This case report highlights the successful management of a non-vital maxillary central incisor with an open apex using MTA apical barrier technique, providing clinical and radiographic healing.
