Management of Maxillary Anterior Tooth with Open Apex by MTA Apexification

Endodontic therapy of teeth with open apex and chronic periapical lesion presents a challenging situation to the clinician. The present case reported outlines treatment of symptomatic maxillary central incisors that have a traumatic history of 15years. The radiographic assessment indicated an underdeveloped apex & chronic periapical lesion. Irrigants, including 3% sodium hypochlorite & 17% EDTA, utilized with ultrasonic activation. Calcium hydroxide utilized as an intracanal medication. Apexification was performed with MTA, then residual canal filled with thermoplasticized gutta-percha. A one-year follow-up revealed nearly complete resolution of the periapical lesion. Thus, central incisor with a chronic periapical lesion and open apex responded well with apexification procedure with MTA (Mineral trioxide aggregate).
