患者,女,48岁,因左上后牙咬合疼痛6天就诊。X线片显示36根尖周远中明显低密度影。CBCT扫描示36腭根根分叉部位明显吸收,累及腭侧根管,三维重建示腭根颊侧及近、远中吸收,腭侧根管暴露。诊断:36牙根外吸收。拔除患牙,腭根折断,取出断根,用树脂粘接剂粘接复位后发现腭根颊侧及近、远中均吸收,其中颊侧吸收累计腭侧根管,导致根管暴露,同CBCT影像一致(图1～3)。
Patient, female, 48 years old, see the upper left posterior teeth bite for 6 days. X-ray film shows 36 weeks in the apparent low density shadow. CBCT scan 36 palate root root bifurcation was significantly absorbed, involving the palatal root canal, three-dimensional reconstruction of the palatal buccal and proximal, distal absorption, palatal root canal exposure. Diagnosis: 36 root absorption. Removal of teeth, palatal root fracture, remove the broken root, with resin adhesive bonding reset found palatal buccal and proximal and distal are absorbed, including the buccal absorption of the total palatal root canal, resulting in root canal exposure, with CBCT Image consistent (Figure 1 ~ 3).
