本研究的目的是提供中国西部人群第三磨牙估计牙龄的参考数据，与其他人群进行比较，并应用于中国西部青少年的年龄估计。共检查了989名男性和1089名女性5 - 23岁中国受试者的2078张数字全景X线照片。使用Demirjian等人描述的形成阶段评估第三磨牙的矿化状态，并进行了两次修改。结果表明，中国西部人群第三磨牙的发育可能开始于5岁，男性和女性都是如此。第三磨牙28和48显示出显着较高的频率在女性比男性。第三磨牙第一阶段18颗，第一、A、G阶段38颗，第三磨牙H阶段48颗，女性平均年龄明显大于男性。Demirjian的C和D阶段可以作为一个参考阶段，以二分法确定西方中国人更可能是14岁以下还是16岁以上。本研究为中国西部青少年第三磨牙矿化分期年龄推断提供了参考数据。除了活体的法医年龄测定外，所提供的参考数据还可用于身份不明的尸体和骨骼的年龄估计。(C)2011爱思唯尔爱尔兰有限公司保留所有权利。
The purpose of this study is to provide reference data about estimating dental age from third molars of the western Chinese population for comparing with other populations and being applied to the age estimation of western Chinese juveniles and adolescents. A total of 2078 digital panoramic radiographs of 989 male and 1089 female Chinese subjects aged between 5 and 23 years were examined. The mineralization status of the third molars was assessed using the formation stages described by Demirjian et al. with two modifications. The results showed that the development of third molars in the western Chinese population was likely to begin at age 5 in both males and females. The third molars 28 and 48 showed significantly higher frequency in females than in males. The third molars 18 in the stage 1, 38 in the stages 1, A and G, and 48 in the stage H showed significantly older average age in females than in males. The Demirjian's stages C and D could be used as a reference stage to determine dichotomously whether a western Chinese is more likely to be under or above age 14 or 16, respectively. This study provided reference data for the age estimation of western Chinese juveniles and adolescents by the mineralization stages of the third molar. Apart from forensic age determination in living subjects, the presented reference data can also be used for age estimations of unidentified corpses and skeletons. (C) 2011 Elsevier Ireland Ltd.
