Teeth may provide useful forensic evidence owing to features like uniqueness, stability and comparability. Moreover, the human dentition is heterodont, i.e. all the teeth have different morphology - incisors, canines, premolars and molars. There are sometimes deviations from normal morphology, such as the presence of extra teeth, variation in their shape and size eg the presence of an extra cusp, fractured crown/root, Carabelli's cusp, peg laterals, transpositions, fusion, etc. These differences can help forensic personnel identify bodies, especially where other methods of identification like facial features, fingerprints or DNA typing cannot yield satisfactory results as in cases of badly decomposed bodies, burnt remains, mass disasters, etc. Identification from dentition is based on the direct comparison of post-mortem dental profiles with ante-mortem dental records of the deceased. This article aims to review these developmental and morphological dental traits and their role in post-mortem identification.
由于牙齿具有独特性、稳定性和可对比性等特征，它们可能提供有用的法医证据。此外，人类的牙列是异形牙，即所有牙齿都有不同的形态——切牙、尖牙、前磨牙和磨牙。有时会出现与正常形态的偏差，例如多生牙的存在、牙齿形状和大小的变化，如额外牙尖的存在、牙冠/牙根骨折、卡氏尖、钉状侧切牙、牙齿移位、融合等。这些差异有助于法医人员识别尸体，特别是在其他识别方法如面部特征、指纹或DNA分型无法得出满意结果的情况下，如尸体严重腐烂、烧焦遗体、大规模灾难等情况。通过牙列进行识别是基于将死后牙齿特征与死者生前牙齿记录进行直接比较。本文旨在综述这些牙齿发育和形态特征及其在死后身份识别中的作用。
