摘　　要：年龄推断是法医学实践中的热点问题,同时也是难点问题。牙齿是人体最坚硬的器官,在体外保存时间较长。随着年龄增长,继发性牙本质逐渐生成,髓腔体积不断减小,法医牙科学家提出通过牙本质-牙髓复合体的增龄性变化来推断年龄。近年来该方法在法医学年龄推断中得到了广泛应用。随着影像学技术的发展,法医牙科学家提出了多种方法评估牙本质-牙髓复合体增龄性变化从而推断年龄,不同测量方法各有优缺点,这要求法医工作者需根据实际情况对多种方法综合运用,提高年龄推断的准确性。本文对国内外利用牙本质-牙髓复合体进行年龄推断的研究现状进行综述,以期对相关领域研究提供参考。Age estimation is a hot and difficult issue in forensic practice.Teeth are the most solid organs in human body and can be kept in vitro for a long time.With age,the secondary dentin gradually generates and the volume of pulp cavity constantly decreases.Therefore,forensic dentists proposed that age-related changes of dentin-pulp complex could be used to estimate age,which has been widely applied in forensic practice over the years.Due to the development of imaging technology,a variety of methods have been advocated by forensic dentists to detect the age-related changes of dentin-pulp complex for age estimation.However,different methods have their own advantages and limitations,forensic scientists should combine the use of different methods for improving the accuracy of age estimation according to the actual situation.This paper reviews current research of age estimation based on dentin-pulp complex,so as to provide reference for related research.
