A retrospective study was carried out on anterior teeth which had undergone apicectomy between 1995 and 1997. More maxillary teeth were treated (94.7%) than mandibular teeth (5.3%). Radicular cyst was the most frequently diagnosed reason for the treatment (47.3%), followed by chronic apical infection/granuloma (44.0%). The overall success rate was 71.9%, while treatment outcome was doubtful in 14.0% of the apicectomised teeth. The presence of pre- or postoperative signs and symptoms did not have any statistically significant effect on the treatment outcome. A higher percentage of roots with retrograde amalgam fillings healed successfully than roots with orthograde fillings, but the difference was not statistically significant (P > 0.05). More lesions classified histopathologically as radicular cysts healed successfully than those classified as granulomas (Fisher exact test, 2-tailed P value = 1.0).
对1995年至1997年间接受根尖切除术的前牙进行了一项回顾性研究。接受治疗的上颌牙（94.7%）比下颌牙（5.3%）更多。根囊肿是最常见的治疗诊断原因（47.3%），其次是慢性根尖感染/肉芽肿（44.0%）。总体成功率为71.9%，而在14.0%的根尖切除牙齿中治疗结果存疑。术前或术后体征和症状的存在对治疗结果没有任何统计学上的显著影响。逆行银汞充填的牙根成功愈合的百分比高于顺行充填的牙根，但差异无统计学意义（P>0.05）。组织病理学分类为根囊肿的病变比分类为肉芽肿的病变成功愈合的更多（Fisher确切概率检验，双侧P值=1.0）。
