摘    要:目的研究Demirjian法推断上海汉族青少年生活年龄的适用性。方法收集上海市第九人民医院符合纳入标准的年龄在11~20周岁的汉族青少年口腔曲面全景片501例.其中男性168例.女性333例。按照Demirjian法进行牙龄推断,并对生活年龄与Demirjian法推断的牙龄进行配对t检验:通过单因素数学模型探索两者之间的关系。结果直接应用Demirjian方法推断上海汉族青少年牙龄时.其推断的牙龄与实际生活年龄之间存在差异。通过建立牙龄推断的单因素数学模型。并将其推断的年龄与实际生活年龄进行配对t检验,结果显示男性12~16周岁(不含16周岁)、女性13~14周岁(不含14周岁)和15~17周岁(不合17周岁)年龄段无统计学意义(P〉0.05),并且有81.04%的样本推断误差小于1岁。结论本研究有望成为推断上海地区汉族青少年生活年龄的有效方法,但不适合17周岁以上青少年人群。

关 键 词:法医牙科学  年龄测定  牙齿  Demirjian法  青少年  汉族
