TREATMENT OUTCOMES OF PERIAPICAL LESIONS IN PERMANENT INCISORS USING CALCIUM HYDROXIDE

Introduction: Periapical lesions could be granulomas or periapical cysts. All periapical lesions should be initially treated with endodontic therapy as an accurate diagnosis cannot be made through clinical assessment alone. Calcium hydroxide, introduced by Hermann in 1920, has been considered to be a very effective intracanal dressing, especially in necrotic teeth with periapical lesions. This study aims to evaluate clinical outcomes of Calcium hydroxide in treatment of periapical lesions in permanent incisors. Methodology: Descriptive study, interventional study. A total of 21 patients with 30 teeth in Department of Endodontics – Periodontics at Hue Odonto - Stomatology Hospital were included in this study. Results: - In total, after 3 months: healed 16.7%; healing 16.7%; not healed 66.6%. After 6 months: healed 43.3%; healing 30%; not healed 26.7%. Group 1: after 3 months: healed 19.2%; healing 15.4%; not healed 65.4%. After 6 months: healed 46.2%; healing 34.6%; not healed 19.2%. Group 2: after 3 months: healed 0%; healing 25%; not healed 75%. After 6 months: healed 25%; healing 0%; not healed 75%. Conclusions: The use of Calcium hydroxide as an intracanal treatment appeared to facilitate healing in periapical lesions associated with chronic apical periodontitis. This is a cheap and simple therapy associated with a high rate of success. Keywords: Periapical lesions, permanent incisors, Calcium hydroxide
