The aim of this is to evaluate the prevalence and location of the accessory mental foramen (AMF) in a Saudi population using cone-beam computed tomography (CBCT)
CBCT data were retrieved from two dental facilities at two universities located in two different cities and filtered over a period of four years. The scans were aligned when the AMF was noticed, and then the size of both the AMF and mental foramen (MF), its location, and the distance from the AMF to the MF were recorded. The AMF measurements were compared between males and females and between the two sides of the mandible.
In total, 603 CBCT scans were investigated. The percentage of scans with an AMF was 9.95% (n = 60), and AMFs were almost equally distributed on both sides. Only four cases (0.66%) of a second AMF were detected among the scans. The MFs on both sides were significantly larger in males than in females (P > 0.05), but they showed no differences in the sizes of the AMFs. The AMFs were most commonly located inferior and posterior to the MF. The distance between the MF and AMF ranged from 2.32 to 5 mm.
The prevalence of the AMF in this Saudi population was 9.95%, and it was significantly more prevalent in males than in females. Its proximity to the MF makes it clinically important to conduct proper detailed planning prior to performing any procedure that might risk the vital structures.
本研究旨在使用锥形束计算机断层扫描（CBCT）评估沙特人群中副颏孔（AMF）的患病率及位置。
从位于两个不同城市的两所大学的两个牙科机构检索CBCT数据，并在四年时间内进行筛选。当发现AMF时，对扫描图像进行对齐，然后记录AMF和颏孔（MF）的大小、位置以及AMF到MF的距离。比较男性和女性之间以及下颌骨两侧的AMF测量值。
总共调查了603例CBCT扫描。有AMF的扫描比例为9.95%（n = 60），且AMF在两侧分布几乎相等。在扫描中仅检测到4例（0.66%）第二个AMF。男性两侧的MF明显大于女性（P > 0.05），但AMF大小无差异。AMF最常见于MF的下方和后方。MF与AMF之间的距离为2.32至5毫米。
该沙特人群中AMF的患病率为9.95%，男性患病率明显高于女性。其与MF的接近程度使得在进行任何可能危及重要结构的手术之前进行适当详细的规划在临床上具有重要意义。
