Reports in specialized literature present divergent opinions about what corresponds to the radiopaque areas surrounding the lingual foramen. The purpose of this study is to radiographically evaluate whether these areas correspond to the genial tubercles.
We selected 15 dry mandibles and obtained images of the lower incisors region by computed tomography (CT) and periapical radiography at vertical angles of -10 degrees, -20 degrees and -30 degrees. For periapical radiography, the genial tubercles and the lingual foramen were marked with stainless steel wire to demonstrate the relationship between them.
The images on periapical radiographs, as well as on CT scans of the region, showed that there is no relationship between radiopaque areas around the lingual foramen and the genial tubercles.
The radiopaque area surrounding the lingual foramen corresponds to the walls of a nutrient canal and not to the genial tubercles. Therefore, we recommend that the information about this anatomical landmark be reviewed in specialized literature.
专业文献中的报告对于舌孔周围不透射线区域的对应结构存在不同观点。本研究的目的是通过影像学评估这些区域是否对应颏结节。
我们选取了15具干燥下颌骨，通过计算机断层扫描（CT）以及在垂直角度为-10度、-20度和-30度时进行根尖片摄影，获取下颌切牙区域的图像。对于根尖片摄影，用不锈钢丝标记颏结节和舌孔，以显示它们之间的关系。
根尖片以及该区域的CT扫描图像显示，舌孔周围的不透射线区域与颏结节之间没有关系。
舌孔周围的不透射线区域对应于营养管的管壁，而非颏结节。因此，我们建议在专业文献中对这一解剖标志的相关信息进行修订。
