Endodontic Management of External Apical Root Resorption: A Case Report

Abstract

Resorption is the combination of either physiological or pathological factors that results in the loss of dentin, cementum, and the alveolar bone of tooth structure due to the action of polynuclear giant cells. The most frequent causative factor for resorption is local factors, notably excessive pressure and inflammatory process. Different types of resorption have been classified depending upon its etiology and site, and different treatment regimens have been proposed based on the type of resorption present. External apical root resorption is usually pathological. The case in this article demonstrates external root resorption managed with nonsurgical root canal therapy with the use intracanal medicament of calcium hydroxide, with 1 month follow-up revealing arrest of resorption. Subsequent follow-up at 6 months shows complete repair of periradicular and furcation area.
