INTRODUCTION
The purpose of this study was to find a correlation between sella turcica bridging and the presence of a palatal impacted canine, using lateral cephalograms and CBCT.
MATERIAL AND METHOD
We selected the lateral cephalograms and CBCTs of 60 patients meeting specific criteria. The radiographs were analysed to study the relationship between sella turca bridging and several factors. The presence or absence of a partial or total bridging was deducted by measuring the dimensions of the sella turcica and by using an accurate scoring system.
RESULTS AND CONCLUSION
Our study did not show any statistically significant association between sella turcica bridging as diagnosed on the lateral cephalogram and the CBCT images and the following factors: age, gender, facial type, skeletal class and the presence of an impacted canine. We found a significant difference for the classification of the sella turcica between these two radiographic methods.
引言
本研究的目的是利用头颅侧位片和锥形束计算机断层扫描（CBCT）找出蝶鞍桥接与腭侧阻生尖牙之间的相关性。
材料与方法
我们选取了60例符合特定标准患者的头颅侧位片和CBCT。对这些X线片进行分析，以研究蝶鞍桥接与几个因素之间的关系。通过测量蝶鞍的尺寸并使用精确的评分系统来判断是否存在部分或完全桥接。
结果与结论
我们的研究未显示出头颅侧位片和CBCT图像上诊断出的蝶鞍桥接与以下因素之间存在任何统计学上的显著关联：年龄、性别、面部类型、骨骼类型以及阻生尖牙的存在情况。我们发现这两种影像学方法在蝶鞍分类上存在显著差异。
