The aim of the present study was to perform quantitative and mathematical analysis of mental foramen (MF) along with its correlation with study subject's sex and age using three-dimensional imaging like cone-beam computed tomography (CBCT).
The CBCT scan images stored in the database were used in this study. Two-hundred sixty-seven scans were selected. They were divided into four different age-groups. These age-groups were 16-23 years, 24-38 years, 39-55 years, and more than 56 years. Each age-group was further divided into two subgroups. One subgroup was of males, while the other subgroup was of females. Following this, there was evaluation of all CBCT-scanned images considering certain parameters like position of MF, size of MF, distance X, distance Y, and distance Z.
The MF was located generally apically to the premolar and molar. It was more commonly located between the first premolar and second premolar among females, while in males, it was mostly located along the long axis of the second premolar. In most of the age-groups, the MF was located between the long axis of the first premolar and second premolar. The average distance of MF from the apex of first premolar was 5.01 mm. Further, the average size of MF and its distance from the base of the mandible were greater in males as compared with females. When all these measurements were compared in different age-groups, the difference was not statistically significant.

When the measurements were compared in different age-groups, then the difference was not statistically significant.
MF is an important structure in the mandible because it acts as an important landmark in the anesthetic procedure; therefore, there was a need to carry out detailed quantitative and mathematical analysis for MF.
本研究的目的是使用三维成像（如锥形束 CT）对心理牙门（MF）进行定量和数学分析，并分析其与研究对象性别和年龄的相关性。
本研究使用存储在数据库中的 CBCT 扫描图像。选择了 267 个扫描图像。他们被分为四个不同的年龄组。这些年龄组分别为 16-23 岁、24-38 岁、39-55 岁和 56 岁以上。每个年龄组进一步分为两个亚组。一个亚组是男性，另一个亚组是女性。随后，评估所有 CBCT 扫描图像，考虑 MF 的位置、MF 的大小、距离 X、距离 Y 和距离 Z 等参数。
MF 通常位于前磨牙和磨牙的根尖上方。在女性中，MF 更常见于第一前磨牙和第二前磨牙之间，而在男性中，MF 主要位于第二前磨牙的长轴上。在大多数年龄组中，MF 位于第一前磨牙和第二前磨牙的长轴之间。MF 距第一前磨牙根尖的平均距离为 5.01 毫米。此外，MF 的平均大小及其距下颌骨基底的距离在男性中大于女性。当比较不同年龄组中的所有这些测量值时，差异没有统计学意义。

MF 是下颌骨中的一个重要结构，因为它是麻醉程序中的一个重要标志；因此，需要对 MF 进行详细的定量和数学分析。
