Nonsurgical Retreatment of Lower Incisor with Apical Lesion

Abstract

ABSTRACT Orthograde retreatment is the first choice to manage an endodontic failure, because surgical approach not always eliminates from the root canal all those microorganisms that caused the failure. Endodontic surgery is commonly performed, when the root canal space is no longer accessible as a result of the presence coronal obstacles. But this case report demonstrates that the attempt to removal of prosthetic crown and post allows to create the right access and then to perform an adequate shaping, cleansing and sealing of the root canal system, even if the chronic periapical pathology induced an initial apical resorption. When the apical diameter is increased, perfect obturation with gutta-percha is not possible, and the apical sealing can be managed with mineral trioxide aggregate (MTA). Follow-up intraoral periapical radiograph at 20 months shows adequate repair of the periapical rarefaction. How to cite this article Dagna A, Saini R.
