Kleier DJ. Nonsurgical retreatment of a postsurgical endodontic failure. J Endod 1984; 10: 577–579

A 45-yr-old Caucasian woman was referred by her family dentist because of pain and periapical pathology associated with both her maxillary central incisors. The teeth had been endodontically treated and retrofill amalgams had been placed. Both teeth were diagnosed as postsurgical endodontic failures. The teeth were retreated nonsurgically. An 18-month recall examination showed normal soft tissue anatomy and an apparent decrease in the size of the periapical radiolucencies. Nonsurgical retreatment of postsurgical endodontic failures is an alternative to reoperation or extraction.
