To examine mental foramen (MF) morphology and morphometry in comparison with ultrasonography (USG) and cone-beam computed tomography (CBCT), and to determine the relationship between mental artery blood flow parameters and age, gender, dental status, alveolar crest height, mandibular cortical index (MCI) with USG.
A total of 120 MF and mental arteries of 60 patients (21 males and 39 females), including 20 patients in each group, aged 18-39, 40-59, and 60 years and above, were evaluated. The horizontal and vertical diameter of the MF and the distance between it and the alveolar crest were evaluated with USG and CBCT. In addition, mental artery blood flow parameters were examined by USG.
When the horizontal diameter values of MF were compared in USG and CBCT measurements; the diameter was significantly lower in the measurements obtained by USG (p < 0.05). It was observed that there were no mental arteries whose blood flow could not be recorded, 31 (25.8%) had strong blood flow and 89 (74.2%) had weak blood flow. No significant correlation was observed between gender and blood flow parameters (p > 0.05).
Considering that CBCT images are used as gold standard in our study, it may be said that USG is not as reliable as CBCT in evaluating the MF dimensions in the maxillofacial region. Nevertheless, USG is a suitable technique for determining the visualizing and blood flow of the MF.
通过与超声（USG）和锥形束计算机断层扫描（CBCT）比较，研究颏孔（MF）形态和形态测量，并确定MF 血流参数与年龄、性别、牙齿状况、牙槽嵴高度、下颌皮质指数（MCI）与 USG 之间的关系。
共评估了 60 名患者（21 名男性和 39 名女性）的 120 个 MF 和颏动脉，每组 20 名，年龄 18-39、40-59 和 60 岁及以上。使用 USG 和 CBCT 评估 MF 的水平和垂直直径以及它与牙槽嵴之间的距离。此外，通过 USG 检查 MF 血流参数。
当比较 USG 和 CBCT 测量的 MF 水平直径值时；USG 测量的直径明显较低（p<0.05）。观察到没有血流无法记录的 MF 动脉，31（25.8%）有强血流，89（74.2%）有弱血流。性别与血流参数之间未见显著相关性（p>0.05）。
考虑到在本研究中 CBCT 图像被用作金标准，可以说 USG 在评估颌面区域的 MF 尺寸方面不如 CBCT 可靠。然而，USG 是一种确定 MF 可视化和血流的合适技术。
