牙齿形态图像的记录与鉴定

Record and Identification of Dental Morphology Image

在现代法庭科学中,人体特征识别主要采用下列四种技术:指纹识别、虹膜纹识别、DNA技术和牙齿形态识别。指纹载体是综合性有机物,虹膜是软组织,在重大灾难性案件中,他们极易毁坏,且我国尚未建立非犯罪人口档案库。DNA技术虽然鉴定精确,但成本高,检验周期较长,因此三种技术都有不足之处。相比之下牙齿形态鉴定法效果较好,本文对此作详细介绍。

In modem forensic science, four techniques for body features identification are widely used, i.e. fingerprint identification, eye cornea identification, DNA technique and dental morphology identification. Eye comea is a soft issue, fingerprints are generally located on orgamc substances, so both are often destroyed seriously in Mass Disaster , still we haven＇t compiled complete archives over all the country; though DNA technique can offer very precise data, but it is expensive and needs time. In Mass Disaster, on the other side, identification of dental morphology image can solve the above problems and perform very satisfactorily, so this paper presents a comprehensive description of that method.
