reatment of an Immature Tooth Using Calcium Hydroxide Medicament: A Case Report

The treatment of an immature tooth with pulp necrosis and apical periodontitis is a major challenge for clinicians. The endodontic treatment of such teeth entails apexification, apical barriers, or more recently, revascularization. The current study reports an immature replanted tooth treated with calcium hydroxide medicament. A 13-year-old female patient with a history of abscess formation in tooth #45 was referred to the Department of Endodontics, Shiraz Dental School, Shiraz, Iran. The clinical and radiographic examinations revealed a necrotic pulp, a root with an open apex, and periradicularradiolucency.

The treatment was rendered under rubber dam isolation and local anesthesia.The root canal was irrigated with 2.5% sodium hypochlorite solution and medicated with calcium hydroxide. Thepatient did notreturn for the completion of treatment in the next session. Twelve months later, she returned to the Department; she was asymptomatic and the root development was observed. The canal was then dried with paper points and obturated with thermoplastic injection technique.
