Age estimation is a critical aspect of human identification. Age is assessed using cranial suture obliteration, pelvic morphological changes, epiphyseal fusion of long bones, dental maturation, and other standard methods.
The present study investigated three-dimensional (3D) computed tomography (CT) scans of 263 individuals (183 males and 80 females) to assess the extent of ectocranial suture closure. The assessment of obliteration was done using a three-stage scoring method. Spearman's correlation coefficient (p < 0.05) was calculated to assess the relationship between cranial suture closure and chronological age. Simple and multiple linear regression models were developed using the cranial suture obliteration scores to estimate age.
The standard errors of the estimate using multiple linear regression models developed for estimating age using obliteration scores of sagittal, coronal, and lambdoid sutures were 15.08 years in males, 13.27 years in females, and 14.74 years in the total study population.
This study concludes that in the absence of additional skeletal age markers, this method can be used alone or in conjunction with other well-established methods of age assessment.
年龄估计是人类身份识别的关键方面。年龄通过颅缝闭合、骨盆形态变化、长骨骺融合、牙齿成熟度以及其他标准方法进行评估。
本研究对263名个体（183名男性和80名女性）的三维（3D）计算机断层扫描（CT）进行了研究，以评估颅外缝闭合的程度。使用三阶段评分法对闭合情况进行评估。计算斯皮尔曼相关系数（p < 0.05）以评估颅缝闭合与实际年龄之间的关系。使用颅缝闭合评分建立简单和多元线性回归模型来估计年龄。
使用为通过矢状缝、冠状缝和人字缝的闭合评分估计年龄而建立的多元线性回归模型，估计的标准误差在男性中为15.08岁，女性中为13.27岁，在整个研究人群中为14.74岁。
本研究得出结论，在没有其他骨骼年龄标记的情况下，该方法可单独使用或与其他成熟的年龄评估方法结合使用。
