Clinical and radiological findings in two groups of patients in whom apicectomies were done are presented. In one group root canal filling was by means of phosphate cementum; in the other, Diaket and guttapercha points were used. Evaluation was according to the methods applied already by Lüders in 1990. Preoperative diagnoses most often had been chronic periapical periodontitis followed by traumatic injuries to frontal teeth and complications encountered during endodontic treatment. In those persons in whom phosphate cementum had been applied, treatment was successful in 210 teeth (77.2%) and a failure was noted in 62 teeth (22.8%). In the Diaket/guttapercha group the success rate was 167 teeth (80.7%), while treatment was without success in 40 teeth (19.3%).
本文呈现了两组接受根尖切除术患者的临床和影像学检查结果。一组患者采用磷酸牙骨质进行根管充填；另一组则使用Diaket和牙胶尖。评估依据的是吕德斯于1990年已应用的方法。术前诊断最常见的是慢性根尖周炎，其次是前牙外伤以及牙髓治疗过程中遇到的并发症。在使用磷酸牙骨质的患者中，210颗牙齿治疗成功（77.2%），62颗牙齿治疗失败（22.8%）。在使用Diaket/牙胶尖组中，成功率为167颗牙齿（80.7%），40颗牙齿治疗未成功（19.3%）。
