Non Surgical Management of Large Periapical Lesion with Mineral Trioxide Aggregate and 4 Years Follow up after Unintentional Extrusion of MTA in Periapical Area: A Case Report

The immature root (open apex) with a necrotic pulp and apical pathosis presents multiple challenges to successful treatment and is difficult to treat with conventional root canal therapy. Mineral Trioxide Aggregate (MTA) has been successfully used in treatment of open apex. Extrusion of MTA through an open apex is not a commonly seen during the apexification procedure. Here we report the management of a case of a non-vital maxillary incisor with immature root. In this case despite of the use of an apical matrix, accidental extrusion of MTA occurred in the periapical region which did not show any negative effect on healing.
