摘要: 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χ2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。

Abstract: PURPOSE: To investigate the association between palatally displaced canines and cervical skeletal abnormalities by lateral cephalometric, panoramic radiographs and cone-beam CT. METHODS: One hundred and three patients with palatally displaced canines were chosen as the experimental group, and 103 patients with Class I and normal canines eruption were as the control group.The data of the first four cervical fusions and posterior arch defects were measured on the lateral cephalometrics. The relationship of the cervical skeletal abnormalities and palatally displaced canines was analyzed with SPSS 21.0 software package for Chi-square test. RESULTS: The incidence of cervical fusion in the experimental group was 71.84%(74 cases), while 15.53% (16 cases) in the control group; the difference between the experimental group and the control group was significant (P<0.001); the incidence of posterior arch defects in the experimental group was 10.68% (11 cases) and 4.85%(5 cases) in the control group; the difference between the experimental group and the control group was not significant. CONCLUSIONS: There is an obviously increasing occurrence rate of cervical skeletal abnormalities in patients with palatally displaced canines, and cervical vertebra bone abnormalities can be combined with other diagnostic parameters to confirm the situation of impacted canines.
