Abstract

Accurate age estimation is an integral part of the identification process. Although used infrequently when compared to more established methods, the Haavikko method can be used in cases where other dental age estimation methods have proven ineffective.The aim of this study was to adapt the Haavikko method as a means of improving age estimation on a representative sample of Croatian children and to establish an applicable standard for the Haavikko developmental stages. To achieve this objective, digital, standardized orthopantomograms of children aged 5 to 16 were collected in four Croatian cities in 1997. Drawing upon a previously published study of the Croatian population, a simple adaptation named 'shift' was introduced to the Haavikko method by adding the average difference between chronological and dental age to the estimated dental age. Square deviations were used to compare the results of the original Haavikko method with the 'shift' adaptation. Accuracy of age estimation was presented as the percentage of correct estimations within intervals of ±0.5 years, ±1 year, ±1.5 years and ±2 years. The 'shift' adaptation was tested through simulation to assure population applicability. The average age for every stage of each permanent tooth was then calculated to provide Croatian specific tables for the Haavikko method. The 'shift' adaptation significantly improved age estimation accuracy among boys and girls in all age groups. Simulation confirmed the representativity of the sample and its population applicability. The Croatian specific tables comprise a standard when estimating age using the Haavikko method among Croatian children.

“转变”适应和哈维科发展阶段的时间新的克罗地亚标准。
准确的年龄估计是鉴定过程中不可或缺的一部分。虽然与更成熟的方法相比,Haavikko方法很少使用,但在其他牙齿年龄估计方法被证明无效的情况下,可以使用Haavikko方法。这项研究的目的是调整Haavikko方法,作为改进克罗地亚儿童代表性样本的年龄估计的手段,并为Haavikko发展阶段建立一个适用的标准。为了实现这一目标,1997年在克罗地亚的四个城市收集了5至16岁儿童的数字化、标准化的正骨断层摄影。根据先前发表的一项关于克罗地亚人口的研究,Haavikko方法引入了一个简单的适应方法,即将实际年龄和牙齿年龄之间的平均差异添加到估计的牙齿年龄中,称为“移位”。使用平方偏差来比较原始Haavikko方法与“移位”适应的结果。年龄估计的准确性以正确率在±0.5年、±1年、±1.5年和±2年区间内的百分比表示。通过模拟验证了“移位”适应性,以保证群体适用性。然后计算每颗恒牙每个阶段的平均年龄,为Haavikko方法提供克罗地亚特定的表格。“移位”适应显著提高了所有年龄组男孩和女孩的年龄估计准确性。仿真验证了样本的代表性和总体适用性。克罗地亚特有的表格构成了使用Haavikko方法估计克罗地亚儿童年龄的标准。
