目的 :通过头影测量片、曲面平展片、锥形束CT检测腭侧埋伏阻生尖牙与颈椎骨骼异常之间是否存在关联。方法:选取103例腭侧埋伏阻生尖牙患者作为实验组,103例尖牙正常萌出的安氏I类患者作为对照组,头影测量片记录前4个颈椎融合和环椎后弓缺陷的数据。采用SPSS21.0软件包对腭侧埋伏阻生尖牙与颈椎骨骼异常之间的关系进行χ~2检验。结果:实验组的颈椎融合发生率为71.84%(74例),而对照组为15.53%(16例),实验组显著高于对照组(P<0.001);实验组的环椎后弓缺陷发生率为10.68%(11例),而对照组为4.85%(5例),实验组和对照组之间无显著差异。结论:腭侧埋伏阻生尖牙患者颈椎骨骼异常的发生率明显增加,颈椎骨骼异常可以配合其他诊断参数,确认尖牙埋伏的情况。
OBJECTIVE: To determine whether there is a correlation between the impacted canines of the palatal palate and the cervical skeletal abnormalities by cephalometric slices, curved surface flat sheets and cone beam computed tomography. Methods: A total of 103 patients with impacted canines with palatal ligaments were selected as the experimental group and 103 patients with Class I patients with normal canines edema were selected as the control group. Cephalometric films were recorded before the four cervical spondylolysis and posterior arch defects data. The SPSS21.0 software package was used to test the relationship between the impacted canines of the palatal obstruction and the skeletal abnormalities of the cervical spine. Results: The incidence of cervical fusion in the experimental group was 71.84% (74 cases), while that in the control group was 15.53% (16 cases). The experimental group was significantly higher than the control group (P <0.001) The rate was 10.68% (11 cases), while the control group was 4.85% (5 cases). There was no significant difference between the experimental group and the control group. Conclusion: The incidence of cervical skeletal abnormalities in palatal impacted canines is significantly increased. The abnormalities of cervical spine may cooperate with other diagnostic parameters to confirm the canine ambush.
