摘要： 目的 运用Demirjian法和Cameriere法测定湖南省汉族青少年的牙龄，并比较两者结果的准确性。 方法 2016年1月—2017年7月，从中南大学湘雅口腔医院收集湖南省无特殊疾病、营养状况良好的8~16岁汉族青少年的口腔全景片480例，其中男性236例，女性244例。分别依照Demirjian法和Cameriere法测定每个青少年的牙龄，利用SPSS 20.0软件对两种方法测得的牙龄与实际年龄进行配对t检验，比较推测牙龄与实际年龄的差异。 结果 男性样本的平均实际年龄为11.91岁，女性样本的平均实际年龄为11.88岁。Demirjian法测得的牙龄比实际年龄平均低估了0.11岁（男性）和0.15岁（女性）。Cameriere法测得的牙龄比实际年龄平均低估了0.83岁（男性）和0.72岁（女性）。 结论 Demirjian法在推断湖南省汉族青少年牙龄时比Cameriere法准确，更适用于该地区青少年牙龄的测定。

Abstract: Objective To apply Demirjian’s and Cameriere’s method for dental age estimation of adolescents from Hunan Han nationality, and compare the accuracy of the two methods. Methods A total of 480 orthopantomograms of 8-16 year old adolescents from Hunan Han nationality with no special diseases and good nutritional status were collected by Xiangya Stomatological Hospital of Central South University from January, 2016 to July, 2017, among them 236 males and 244 females. The dental age of each adolescent was determined by Demirjian’s method and Cameriere’s method, respectively, and the paired t-test of the estimated dental age and the chronological age determined by the two methods was conducted by SPSS 20.0 software to compare the difference between estimated dental age and chronological age. Results Mean chronological age of males and females was 11.91 and 11.88 years, respectively. The estimated dental age determined by Demirjian’s method showed an underestimate of chronological age by an average of 0.11 years （males） and 0.15 years （females）, while the estimated dental age determined by Cameriere’s method showed an underestimate of chronological age by an average of 0.83 years （males） and 0.72 years （females）. Conclusion Demirjian’s method is more accurate than Cameriere’s method in dental age estimation of adolescents from Hunan Han nationality, therefore more suitable for dental age estimation of adolescents in this region.
