Analysis of some anatomical structures of the face using radiographs is fundamental for human identification. The position of the postmortem skull relative to the radiographic machine and the film, as well as the exposure time, are the greatest problems found by the forensic dentist. In view of this fact, some recognised radiographic techniques that are used in vivo must be adapted. This paper shows that simple devices can make the process easier and that variation of kVp or exposure time in different situations may increase the quality of the radiographs.
利用X光片分析面部的一些解剖结构对人类身份识别至关重要。法医牙医发现，尸体颅骨相对于X光机和胶片的位置以及曝光时间是最大的问题。鉴于这一事实，一些在活体中使用的公认的X光技术必须加以调整。本文表明，简单的设备可以使这一过程更简便，并且在不同情况下改变千伏峰值（kVp）或曝光时间可能会提高X光片的质量。
