摘要： 目的对应用Demirjian法进行法医学年龄推断的准确度及可靠性进行初步评价。方法应用Demirjian法测定828名上海地区青少年(男279名,女549名,11～19周岁)的牙龄,比较所测牙龄和实际年龄的差异。结果在11～14岁年龄段Demirjian法测定的牙龄比实际年龄高估,在15～16岁年龄段低估,在17岁及17岁以上年龄段具有局限性。结论Demirjian法可以用于测定上海地区11～16岁年龄段青少年的牙龄,使用时需进行适当的修正。

Abstract: Objective Developing teeth are used to assess maturity and estimate age in a number of disciplines.The aim of this study was to determine the accuracy of Demirjian method(Panoramic radiographs were examined and seven mandibular teeth staged according to Demirjian′s dental maturity scale) in the forensic clinical medicine.Methods Tooth formation was assessed with orthopantomographs in healthy children in dental teaching hospital.There were total 828 children,with 279 boys and 549 girls,aged from 11 to 19 years.The difference between dental and real age was compared and measured,using t-test.Results The Demirjian method overestimated age in the aged 11-16 years group and had limitations in aged group over 17 years.Conclusion The 95% confidence interval of the mean was least for mean of all developing teeth using Demirjian method(age 11-16 years).
