摘要/Abstract

摘要： 目的: 评价Demirjian和Chaillet法在评估乌鲁木齐地区维汉儿童及青少年实际年龄中的适用性和准确性。方法: 纳入乌鲁木齐市儿童全口曲面体层片1 144张,根据2种牙龄推断方法对左侧下颌7颗恒牙判定不同分期,查表赋分后转换为牙龄,采用SPSS 21.0软件包,对牙龄与实际年龄进行配对t检验或秩和检验,通过比较2种方法的平均绝对误差,对2种方法的准确性进行评价。结果: Demirjian法在汉族人群中平均高估0.46岁（男0.47岁,女0.43岁）;在维吾尔族人群中平均高估0.36岁（男0.44岁,女0.26岁）,在维汉男孩人群中差异有统计学意义（P<0.05）;Chaillet法在汉族人群中平均低估0.01岁（男0.04岁,女-0.08岁）,在维吾尔族人群中,平均低估0.08岁（男0.02岁,女-0.21岁）,维汉男女孩差异无统计学意义（P>0.05）。结论: 在评估乌鲁木齐地区维汉儿童及青少年年龄时,Chaillet法较Demirjian法准确。不同地区应用牙龄推断法时,需先评估推断方法的准确性,必要时加以修正,以提高精确性。

Abstract: PURPOSE: To evaluate the applicability and accuracy of Demirjian and Chaillet method in estimating the actual age of Uygur and Han children and adolescents in Urumqi. METHODS: A total of 1144 orthopantomograms were included in the study, and the seven permanent teeth in the left jaw were divided into different stages according to two dental age estimation methods, and the dental age was converted to tooth age after checking the table and assigning points, and the dental age and its chronological age were compared with t test or rank sum test using SPSS 21.0 software package, and the accuracy of the two methods was evaluated by comparing the mean absolute error of the two methods. RESULTS: Demirjian method was overestimated by an average of 0.46 years (0.47 years for males and 0.43 years for women) in the Han population, 0.36 years for men and 0.26 years for women in Uyghur population, the difference was significant between Uyghur and Han boys (P<0.05). Chaillet method yielded an average underestimate of 0.01 years (0.04 years for men and -0.08 years for women) in the Han population, and 0.08 years(0.02 years for men and -0.21 years for women) in the Uyghur population, there was no significant difference between Uyghur and Han boys and girls(P>0.05). CONCLUSIONS: When assessing the age of Uyghurhan children and adolescents in Urumqi, Chaillet method is more accurate than the Demirjian method. When applying dental age estimation method in different regions, it is necessary to evaluate the accuracy of the estimation method and revise it if necessary to improve the accuracy.
