牙齿是人体内最坚硬、理化性状及稳定性均很高的组织,且随年龄增长呈规律性的变化。人死后牙齿变化最慢,对外界环境变化的耐力较大,所以,根据牙齿磨耗程度判定年龄,越来越受到基层的重视。我们在1988年底以来的3年中,对18具无名尸体进行了根据牙齿磨耗程度判定牙龄,均取得满意的效果,在认定死者、个人识别以及为侦察破案提供明确的方向,为打击罪犯提供可靠的证据等方面起到了较大的作用。
Teeth is the hardest body in the human body, physical and chemical properties and stability of tissues are very high, and regular changes with age. People die after the slowest changes in teeth, changes in the external environment, greater endurance, therefore, according to the degree of tooth wear to determine the age, more and more grass-roots attention. In the three years since the end of 1988, we conducted satisfactory tests on 18 unnamed corpses to determine the age of our teeth according to the degree of tooth wear. We have provided a clear direction for the identification of dead and individuals as well as for the detection and prosecution of offenders, providing counter-offenders Reliable evidence has played a greater role.
