The prospective randomised study on the root apex resections with orthograde root filling comparing Guttapercha with Titan pins encompasses 500 patients with 633 operations on all front teeth and premolars. The patients were divided into three preoperative stages so that for this broadly defined diagnoses comparable collectives could be built. After an average postoperative interval of 21 months, 258 patients with 298 resected teeth could be evaluated. From these, 188 root apex resections had been treated with Guttapercha and 110 with Titan pins. 73.5% of the root apex resections were successful, whereby the group treated with Guttapercha was more successful by 7%. The comparatively high failure rate of 26.5% is attributable to the broadly defined diagnosis and the long follow-up period.
一项关于采用垂直根管充填术进行根尖切除术并比较牙胶尖与钛钉的前瞻性随机研究纳入了500例患者，对所有前牙和前磨牙进行了633次手术。患者被分为三个术前阶段，以便针对这种宽泛定义的诊断建立可比的群体。术后平均间隔21个月后，对258例患者的298颗切除牙进行了评估。其中，188例根尖切除术采用牙胶尖治疗，110例采用钛钉治疗。73.5%的根尖切除术成功，其中采用牙胶尖治疗的组成功率高出7%。26.5%的相对较高失败率归因于宽泛定义的诊断和较长的随访期。
