由于对无人陪伴未成年人年龄估计的需求日益增加，成年年龄估计在法医日常实践中具有重要的应用。I3M评估法律的成年年龄18岁的诊断准确性已经在几个特定的人群样本中进行了测试。本研究的目的是比较第三磨牙成熟度指数（I3M）的敏感性和特异性，以探讨不同民族间的差异。为此，对来自15个国家的6157张正射断层摄影（OPG）的样本进行了分析。使用双变量建模方法汇总有关灵敏度和特异性的数据。应用单因素MANOVA分析来评估五个区域组的敏感性和特异性从同一人群中取样的可能性。单因素方差分析结果显示，敏感性和特异性均不依赖于地区组。获得的灵敏度为84%（95%CI：82%和85%），特异性为94%（95%CI：93%和95%）。基于这些结果，I3M是一种有用的统计工具，可用于确定受试者是否达到法律的年龄18岁，无论其种族如何。
Estimation of age of majority has important applications in the forensic daily practice because of the increasing demand for age estimates of unaccompanied minors. Diagnostic accuracy of I3Mto assess legal adult age of 18 years has been already tested in several specific population samples. The aim of this work was to compare the available data about sensitivity and specificity of the third molar maturity index (I3M) from five different regional groups’ radiographic samples to study possible ethnical difference. For this purpose, a sample of 6157 orthopantomograms (OPGs), coming from 15 countries, was analysed. Data about sensitivity and specificity were pooled using a bivariate modelling approach. The one-way MANOVA analysis was applied to assess the likelihood that sensitivity and specificity of the five regional groups are sampled from the same population. The result of the one-way MANOVA showed that both sensitivity and specificity did not depend from the regional groups. The obtained sensitivity was 84% (95% CI: 82% and 85%), and its specificity was 94% (95% CI: 93% and 95%). Based on these results, the I3Mwas a useful statistical tool to identify whether a subject has reached the legal age of 18 years old, regardless of his or her ethnicity.
