摘　　要：近年来,个体年龄推断在法医学实践中逐渐受到关注。常用的年龄推断方法主要是通过骨骼和牙齿发育。与骨骼相比,牙齿更为坚硬且不易受到外部环境影响,因此在年龄推断中具有重要作用。Demirjian法是评估牙龄最常用的方法之一,目前在多个国家得到了广泛应用。本文主要对Demirjian法在不同人群中应用的准确性进行回顾,发现与实际年龄相比,推断年龄大多存在高估现象,结合多位学者的研究结果分析认为,该情况可能与种族、地域、性别等差异具有相关性。In recent years, individual age estimation has gained increasing attention in forensic practice. Common age estimation methods mainly use developments of teeth and bones. Compared with bones, teeth are stronger and are highly resistant to external factors, therefore plays an important role in age estimation. Demirjian’s method is one of the most commonly used methods to evaluate dental age and has been widely used in many countries. In this paper, the accuracy of its application in different populations is reviewed. It is found that compared with the chronological ages, most of the estimated ages are overestimated. By combining research results of many scholars and by analyzing, it can be assumed that this situation may be related with race, region, sex, etc.
