SingleVisit Apexification Technique for Inducing Root-End Barrier Formation in Apical Closures: Report of Two Cases

Traumatized tooth rendered nonvital (pulpal necrosis) before the final stage of the root development results in a short root with a wide canal that can be either divergent or parallel. Although the root canal therapy is the choice of treatment for a nonvital tooth, the above mentioned abnormal root anatomy does not permit a predictable outcome. Mainly, it is not feasible to achieve a good apical seal due to lack of constriction in the open apex and a good lateral seal due to an abnormal width and shape of the root canal. Numerous procedures and materials have been utilized to induce root-end barrier formation. Mineral trioxide aggregate (MTA) reacts with tissue fluids to form a hard tissue apical barrier. As a result, MTA shows promise as a valuable material for use in single-visit apexification treatment, primarily for treating immature teeth with necrotic pulp. Here, we present two cases being successfully treated in a single visit apexification with MTA followed by endodontic treatment.
