This study assessed the associations between chronological age, dental maturation (DM), cervical vertebrae maturation (CVM), and hand-wrist maturation (HWM) in individuals aged 9-19 years. In addition, this study aimed to derive practical methods to evaluate the skeletal age using DM, CVM, or HWM for orthodontic, medical, and forensic purposes and to compare which of these 3 developmental parameters is more accurate for estimating the age of individuals in a Turkish population.
Panoramic, lateral cephalometric, and hand-wrist radiographs of 284 patients aged 9-19 years were used in this study. The DM, CVM, and HWM stages were determined. The Kolmogorov-Smirnov, kappa, Wilcoxon, Kruskal-Wallis, chi-square, and Spearman correlation tests and simple linear regression analysis were used for statistical analysis. The significance level was 0.05.
Statistically significant differences were found between chronological age and DM, chronological age and CVM, and chronological age and HWM in both sexes (<0.05). DM did not show statistically significant differences according to sex (>0.05), but CVM and HWM were statistically different between males and females (<0.05). The DM-estimated age yielded more accurate values than the other methods.
All correlations between skeletal and dental stages were statistically significant. Our results showed that there was no statistically significant difference between chronological age and DM-estimated age. Therefore, it can be concluded that DM stages have the potential to be used for legal purposes.
本研究评估了9至19岁个体的实足年龄、牙齿成熟度（DM）、颈椎成熟度（CVM）和手腕成熟度（HWM）之间的关联。此外，本研究旨在得出实用方法，以便出于正畸、医学和法医目的，使用DM、CVM或HWM来评估骨骼年龄，并比较这三个发育参数中哪一个在估计土耳其人群个体年龄方面更准确。
本研究使用了284名9至19岁患者的全景、侧位头影测量和手腕X线片。确定了DM、CVM和HWM阶段。采用Kolmogorov-Smirnov、kappa、Wilcoxon、Kruskal-Wallis、卡方和Spearman相关性检验以及简单线性回归分析进行统计分析。显著性水平为0.05。
在两性中，实足年龄与DM、实足年龄与CVM、实足年龄与HWM之间均存在统计学显著差异（<0.05）。DM根据性别未显示出统计学显著差异（>0.05），但CVM和HWM在男性和女性之间存在统计学差异（<0.05）。DM估计的年龄比其他方法产生更准确的值。
骨骼和牙齿阶段之间的所有相关性均具有统计学显著性。我们的结果表明，实足年龄与DM估计年龄之间没有统计学显著差异。因此，可以得出结论，DM阶段有可能用于法律目的。
