To compare the images of the mental canal in panoramic radiography (PR) and computed tomography (CT) by analyzing the concordance with diagnostic tests and examiners.
The position of the mental foramen (MF), distance to the lower mandibular border, anterior length of the mental loop (ML), agreement between examiners and diagnostic concordance were registered in 50PR and 50CT.
ML was identified (34.5/41%, PR/CT). PR magnification was 36.6% higher than in CT. The anterior extension and distance to the inferior border of the MF was higher for PR (2-6.2 mm). Inter-examiner agreement on CT was good (κ = 0.628) and very good on PR (κ = 0.845).
There is a magnification (36.6%) of the images in PR with respect to the CT. Identification of MF and ML is not related to the bone quality. Inter-examiner agreement is better on PR.
通过分析与诊断测试和检查者的一致性，比较全景放射摄影（PR）和计算机断层扫描（CT）中颏孔的图像。
在 50 例 PR 和 50 例 CT 中记录颏孔（MF）的位置、距下颌下缘的距离、颏管前长度、检查者之间的一致性和诊断一致性。
识别出颏管（34.5/41%，PR/CT）。PR 的放大率比 CT 高 36.6%。MF 的前伸和距下颌下缘的距离在 PR 中更高（2-6.2mm）。CT 上的检查者之间的一致性良好（κ=0.628），PR 上的一致性非常好（κ=0.845）。
PR 图像相对于 CT 有放大（36.6%）。MF 和 ML 的识别与骨质量无关。PR 上的检查者之间的一致性更好。
