The aim was to compare the vertex occlusal projection with the anterior maxillary occlusal projection in localizing the position of mesiodentes. Mesiodentes were observed in an 8-year-old boy with an anterior maxillary occlusal radiograph. A vertex occlusal radiograph was taken to compare it with the former in terms of mesiodentes localization with respect to the maxillary central incisors. The vertex occlusal radiograph provided greater details of the position and proximity of mesiodentes with respect to the long axis of maxillary central incisors in comparison to the anterior maxillary occlusal radiograph. Vertex occlusal radiography is an important diagnostic tool in diagnosing the presence, position, and proximity of mesiodentes with respect to the long axis of normally aligned maxillary central incisors. However, it is not recommended for routine use in a patient as its radiation dose is higher than conventional intraoral radiographic methods.
目的是比较顶点咬合投照与上颌前部咬合投照在定位正中牙位置方面的效果。在一名8岁男孩的上颌前部咬合X线片上观察到正中牙。拍摄顶点咬合X线片，以便在正中牙相对于上颌中切牙的定位方面与前者进行比较。与上颌前部咬合X线片相比，顶点咬合X线片能提供关于正中牙相对于上颌中切牙长轴的位置和接近程度的更多细节。顶点咬合X线摄影是诊断正中牙相对于正常排列的上颌中切牙长轴的存在、位置和接近程度的重要诊断工具。然而，由于其辐射剂量高于传统口腔内X线摄影方法，不建议在患者中常规使用。
