Non surgical management of large periapical lesion using mta: report of 2 cases

Abstract

In the past, cases with open apices were often treated over several appointments, using calcium hydroxide, with the hope of creating a ‘‘calcific’’ barrier against which gutta percha could eventually be placed. The treatment could be as long and the prognosis is questionable. These roots were often thinner and, therefore, more brittle; extending treatment over a long period of time without providing a permanent restoration increased the chances of losing these teeth due to fracture. With the favorable histologic response of MTA, this material is the best current choice for this procedure. Completion of these cases in an effective and efficient way allows for permanent restorations to be done in a timelier manner, prolonging the longevity of these teeth. The following case report demonstrates the use of MTA as an obturating material to promote periapical healing with an open apex.
