An eight-year-old Victorian koala was presented with a discharging mandibular sinus of at least one month duration. On examination, a dental abscess of the right mandibular incisor tooth was found. During the course of endodontic treatment, a size 2 Gates Glidden bur separated from the shank and was lodged in the canal. Due to the anatomy of the tooth the bur could not be removed and an apicoectomy was performed. Following the apicoectomy (follow-up period two years), the periapical pathology resolved.
一只八岁的维多利亚州考拉出现下颌窦流脓至少一个月。检查时，发现右下颌切牙有牙脓肿。在根管治疗过程中，一个2号盖茨·格利登钻针从柄部分离并卡在根管内。由于牙齿的解剖结构，钻针无法取出，于是进行了根尖切除术。根尖切除术后（随访期两年），根尖周病变得到解决。
