背景：已经提出了许多估计年龄的方法，其中最常用的是德米尔金方法。本研究的目的是测试德米尔金方法在伊朗人口年龄估计中的准确性。材料和方法：通过方便抽样的方法选择141名男孩和170名女孩进行横断面研究。结果：Demirkin法高估了男性0.34岁，女孩高估了0.25岁。男孩和女孩的估计牙龄和实际年龄之间的散点图显示，随着年龄的增加，回归线有减小的趋势。男孩的估计牙龄和实际年龄之间的平均差异随着年龄的增长而减小(除最大年龄组的男孩外)。结论：Demirkin法适用于估算牙龄，尤其适用于9~13岁年龄段的患者。然而，在较年轻的年龄组，需要进一步研究更多的病例。(C)2009爱思唯尔爱尔兰有限公司。保留所有权利。
Background: Many methods of age estimation have been suggested, and of these, the Demirjian method is the most frequently used. The objective of the present study is to test the accuracy of the Demirjian method for age estimation in an Iranian population.Materials and methods: A cross-sectional study involving 141 boys and 170 girls selected by a convenience sampling method was carried out. Panoramic radiography was used to score the left mandibular teeth and to obtain the Demirjian tooth age.Results: The Demirjian method overestimated the age of boys by 0.34 years and girls by 0.25 years. The scatter plots showing the difference between estimated dental age and chronological age for boys and girls showed that the regression lines had a decreasing trend with age. The mean difference between estimated dental age and chronological age in boys decreased with age ( except in the oldest age group of boys). In contrast, it increased in girls between the ages of 6-8 years old, and then decreased.Conclusion: The results show that the Demirjian method is appropriate for estimating the dental age of patients, especially those belonging to the 9-13 year old age group. However, in the younger age groups, further study involving more cases is required. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
