The relation of preoperative and intraoperative factors to the prognosis of apical surgery was studied in 136 premolar and molar roots. The evaluated factors were: clinical signs and symptoms, size of the periapical lesion, root canal obturation, tooth restoration, apical retrofilling, and the operating surgeon. A significantly higher success rate was found in roots obturated 2 mm or shorter of the apex, in roots without post restoration, and after retrofilling of roots with apparently well-condensed obturation. The prognosis differed significantly following treatment by various operators but was unrelated to their experience.
在136颗前磨牙和磨牙牙根中研究了术前和术中因素与根尖手术预后的关系。评估的因素包括：临床体征和症状、根尖周病变大小、根管充填、牙齿修复、根尖倒充填以及手术医生。在根尖充填2毫米或更短的牙根、没有桩修复的牙根以及用明显致密充填物进行根尖倒充填后的牙根中，发现成功率显著更高。不同手术医生治疗后的预后有显著差异，但与他们的经验无关。
