Short-term observation of the results of endodontic surgery with the use of a surgical operation microscope and super-EBA as root-end filling material

Observations were made on the success of endodontic surgery with microsurgical techniques using Super-EBA cement as a root-end filling material. Ninety-four cases were treated by a single clinician over a period of 1 yr and 2 months. All surgical procedures were performed under a surgical operation microscope at magnifications of ×3 to ×26. Recall radiographs were taken at 3-month intervals over a 12-month period until the lamina dura was completely restored or the case had clinically failed. The radiographic success of the 94 cases was 96.8%, and the average time for lesions to heal was 7.2 months.
