Post-treatment apical periodontitis may persist due to biological factors or when primary endodontic treatment has been ineffective in eliminating the intraradicular infection. It may not be appropriate to carry non-surgical endodontic retreatment. This case report was the report of 43 year-old woman with symptomatic apical periodontitis of maxillary right central incisor after primary endodontic treatment with post and bridge abutment restoration. Apical endodontic surgery was performed by apicoectomy and retrograde filling with mineral trioxide aggregate (MTA). MTA had been shown in a number of studies to be a potential root end filling material. After three year follow up, clinical examination showed that the teeth was asymptomatic. A periapical radiograph revealed complete healing of periapical tissue, rendering the successful treatment.</p> ER -
