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(不含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。

Abstract: Objective To study the applicability of Demirjian's method for age estimation in teenagers of Shanghai Han population in China.Methods Paired t-test was performed between the chronological age and the age determined by Demirjian's method of 501 teenagers whose orthopantomograms were collected from the ninth hospital of Shanghai.There were 168 boys and 333 girls involved in this study with chronological age from 11 to 20 years.Uni-factor model was used to explore the relationships of the two kinds of age.Results For the marked difference between the chronological age and determined age,Demirjian's method was not suitable to the Chinese Han adolescents.The results of paired t-test between chronological age and predicted age from quadratic equation showed that there was no significant difference in boys aged 12-16 years,in girls aged 12-14 years and 15-17 years repectively.The uni-factor model could make the error of determined age less than 1 year to 81.04% of the samples.Conclusion The age between 11 and 17 years can be well estimated by our method,except for the 17 years of age and above.
