The aim of this retrospective study was to compare the outcome of surgical endodontic treatment preformed using the traditional versus modern techniques. There were 110 patients who were treated by surgical endodontic treatment between 2000 and 2002 and evaluated from their dental charts. The surgical endodontic treatment was preformed using a traditional or modern technique. The traditional technique included root-end resection with a 45 degrees bevel angle, and retrograde preparation using a carbide round bur. The modern technique included root-end resection with minimal or no bevel, and retrograde preparation using ultrasonic retro-tips with the aid of a dental operating microscope. The retrograde filling material for both techniques was intermediate restorative material. There were 71 patients with 88 treated teeth that were compatible with the inclusion criteria. Complete healing rate for the teeth treated with the modern technique (91.1%) was significantly higher than that for teeth treated using the traditional technique (44.2%) (p < 0.0001). In the traditional technique a significant (p = 0.032) negative influence of the tooth type was found. Modern surgical endodontic treatment using operative microscope and ultrasonic tips significantly improves the outcome of the therapy compared to the traditional technique.
这项回顾性研究的目的是比较采用传统技术与现代技术进行的外科根管治疗的效果。2000年至2002年间，有110例患者接受了外科根管治疗，并根据他们的牙科病历进行评估。外科根管治疗采用传统技术或现代技术进行。传统技术包括以45度斜面角度进行根尖切除术，以及使用硬质合金圆钻进行倒充填预备。现代技术包括进行最小斜面或无斜面的根尖切除术，以及在牙科手术显微镜辅助下使用超声倒充尖进行倒充填预备。两种技术的倒充填材料均为中间修复材料。有71例患者的88颗治疗牙齿符合纳入标准。采用现代技术治疗的牙齿的完全愈合率（91.1%）显著高于采用传统技术治疗的牙齿（44.2%）（p<0.0001）。在传统技术中，发现牙齿类型有显著（p=0.032）的负面影响。与传统技术相比，使用手术显微镜和超声尖的现代外科根管治疗显著改善了治疗效果。
