Endodontic retreatment with MTA Apexification in a maxillary central incisor

The major challenge associated with endodontic treatment of teeth with open apices is achieving a three-dimensional fluid-tight seal of the root canal system. In the absence of a natural apical constriction, it is imperative to create an apical barrier and allow three-dimensional adaptation of obturating material to the root canal system. The case presented here had a history of failed endodontic treatment, extensive root resorption, open apex, and a large periapical lesion associated with a left maxillary central incisor. The use of absorbable gelatin foam in combination with MTA has been recommended in many studies. This article presents a detailed case report of the use of such a matrix for the placement of MTA as an apical barrier. M,29, sought…
