A cystic structure was identified radiographically in a four-year-old dog during routine dental prophylaxis. Surgical removal of the cyst lining was achieved by exposure of the site through extraction of the right first to third maxillary incisor teeth (101, 102, 103). The cyst lining was removed en-bloc. The cavity was curetted and filled with decalcified freeze-dried bone. Histological examination revealed a radicular cyst. The proposed etiology is blunt trauma to tooth 103, pulpal necrosis, apical granuloma and resulting cyst formation. Fourteen months following surgery, there was no recurrence of the cyst.
在对一只四岁犬进行常规牙齿预防保健时，通过影像学检查发现了一个囊性结构。通过拔除右侧上颌第一至第三切牙（101、102、103）暴露该部位，实现了囊肿内衬的手术切除。囊肿内衬被整块切除。对腔隙进行刮治并填充脱钙冻干骨。组织学检查显示为根尖囊肿。推测病因是103号牙受到钝性创伤、牙髓坏死、根尖肉芽肿并由此形成囊肿。术后14个月，囊肿未复发。
