From September 1992 to March 1994 at the Department of Oral Surgery of the Dental School of the University of Vienna a total of 218 microsurgical apicoectomies and ultrasonic retro-preparations were carried out in 142 patients. Among other indications for operation was the failure of previous surgical-endodontic procedures in 62 cases. In 51 teeth (82%) of these patients the cause of failure could be evaluated with the help of the microscope. Twelve teeth (19%) extracted afterwards showed a longitudinal root fracture which had not been diagnosed before. In all other teeth retro-preparation and filling with zincoxide-eugenol cement was possible, even in cases of difficult anatomic approach. Due to the excellent experiences with microsurgical technique in apicoectomies, the use of the microscope in other fields of dental surgery remains only a matter of time.
1992年9月至1994年3月期间，维也纳大学牙科学院口腔外科对142例患者共实施了218例显微外科根尖切除术和超声倒预备术。手术的其他适应证包括62例既往外科牙髓治疗失败的病例。在这些患者的51颗牙齿（82%）中，借助显微镜可以评估失败原因。随后拔除的12颗牙齿（19%）显示存在术前未诊断出的纵形根折。在所有其他牙齿中，即使在解剖入路困难的情况下，也可以进行倒预备并用氧化锌丁香油粘固剂充填。由于在根尖切除术中显微外科技术取得了出色的经验，显微镜在牙科手术其他领域的应用只是时间问题。
