MTA - The Barrier for Endodontic Success!

Abstract

The elimination of microbiological colonization in any parts of human body is a crucial principle of treating infection and root canal system is no exception. The major challenges associated with endodontic treatment of teeth with open apices are achieving complete debridement, canal disinfection and optimal sealing of the root canal system.In the absence of a natural apical constriction, the production of mineralized tissue in the apical region is important to create an apical barrier and allow 3-dimensional adaptation of obturating material within the root canal system.A clinical case of central incisor have been treated with the use of an apical plug of MTA for apexification that had suffered premature interruption of root development as a consequence of trauma.The remaining portion of the root canals was then closed with thermoplasticized gutta-percha. At 6-month follow-up period the clinical and radiographic appearance of the tooth showed resolution of the periapical lesions.
