Endodontic treatment of a tooth with an immature apex poses a lot of challenges. The absence of an apical stop makes obturation and achieving a good apical seal more difficult. Because of their thin walls, these teeth are also more prone to fracture. Apexification with Mineral Trioxide Aggregate (MTA) is the preferred treatment because it creates a calcific barrier at the apex, allowing root canal filling to take place in a more favorable environment. This case report discusses the use of MTA to create a barrier at the apex in a previously root filled discolored maxillary right central incisor with an open apex. MTA aided in the creation of an apical barrier in the maxillary right central incisor with an open apex, resulting in satisfactory clinical and radiographic outcomes.
