Anatomical knowledge is crucial for addressing diagnostic challenges, ensuring safe procedures, and avoiding potential risks. Among the various mandibular anatomical landmarks, the mental foramen (MF) is particularly significant for dental procedures, especially surgeries. Therefore, it is essential to conduct a comprehensive radiographic evaluation of this region before performing such procedures. The purpose of this study was to investigate the size of MF and the distances from its border to the alveolar crest (AC) and to the inferior border of the mandible (IBM) in a selected Syrian population by using cone-beam computed tomography (CBCT), and to detect any statistically significant effect of individuals' factors, such as sex, age, dental status, and side on these anatomical parameters.
The study retrospectively analyzed 200 CBCT scans (400 hemimandibles) from 104 females and 96 males, grouped into three age categories: 20-35, 36-50, and 51-65years. The hemimandibles were classified based on dental status into three groups: dentate, partially edentate, and completely edentate, and by side as right or left.
The study revealed that the average horizontal and vertical diameters of MF were (3.48±0.75mm) and (3.01±0.75mm), respectively. Additionally, the average distances D1 (MF-AC) and D2 (MF-IBM) were (11.01±3.68mm) and (12.51±1.56mm) respectively. The study's findings indicated that age and dental status had a statistically significant effect on all the parameters studied, except for the horizontal diameter. Furthermore, sex had a statistically significant effect on all the parameters, while the side had no effect on any of the parameters investigated.
The results of this study suggest that an understanding of the morphometry of the mental foramen is essential for clinicians, which may assist them in performing dental procedures more safely and achieving successful local anesthesia. Moreover, individual factors should be taken into consideration.
解剖学知识对于解决诊断挑战、确保手术安全和避免潜在风险至关重要。在各种下颌解剖标志中，颏孔（MF）对于牙科手术，特别是手术特别重要。因此，在进行此类手术之前，必须对该区域进行全面的射线照相评估。本研究的目的是通过锥形束计算机断层扫描（CBCT）研究选定的叙利亚人群中 MF 的大小以及其与牙槽嵴（AC）和下颌骨下缘（IBM）的距离，并检测个体因素，如性别、年龄、牙齿状况和侧别对这些解剖参数的任何统计学显著影响。
该研究回顾性分析了 104 名女性和 96 名男性的 200 个 CBCT 扫描（400 个半下颌骨），分为三个年龄组：20-35 岁、36-50 岁和 51-65 岁。根据牙齿状况，半下颌骨分为三组：有牙、部分无牙和完全无牙，并按侧别分为右侧和左侧。
研究表明，MF 的平均水平和垂直直径分别为（3.48±0.75mm）和（3.01±0.75mm）。此外，平均距离 D1（MF-AC）和 D2（MF-IBM）分别为（11.01±3.68mm）和（12.51±1.56mm）。研究结果表明，年龄和牙齿状况对所有研究参数均有统计学显著影响，除水平直径外。此外，性别对所有参数均有统计学显著影响，而侧别对研究的任何参数均无影响。
本研究结果表明，了解颏孔的形态学对于临床医生至关重要，这可能有助于他们更安全地进行牙科手术并实现成功的局部麻醉。此外，应考虑个体因素。
