Studies on forensic age assessment based on dental features

该项目将大大提高根据牙齿特征进行法医年龄评估的可靠性。对于与年龄相关的牙齿特征，从可靠性和诊断质量两方面考虑，确定最适合法医年龄评估的阶段分类，为年龄评估实践提供有效的统计指标作为参考数据。通过样本的平均年龄分布和两名经验丰富的检查员的一致阶段确定，避免了统计偏差（“年龄模仿”）和不正确的阶段确定。种族对检查牙齿特征的可疑影响是由年龄和性别匹配的主要种族群体的法医年龄评估相关的样本（欧洲人，亚洲人，非洲人），以及由一致同意的阶段确定相同的经验丰富的考官澄清。采用系统的模拟研究，比较各研究小组公布的统计方法对预定年龄限制的分类和特征的组合。从而确定最合适的预测模型，提高法医学年龄鉴定实践中年龄诊断的可靠性。该项目具有重大的社会政治意义。预期的研究结果对许多其他欧洲国家的法医年龄评估也很重要，在这些国家，法律上相关的年龄限制在该项目所涵盖的年龄范围内。

The project will significantly improve the reliability of forensic age assessment on the basis of dental features. For the relevant age-dependent dental characteristics, the most suitable stage classifications for forensic age assessment will be determined with regard to reliability and diagnostic quality.For the age estimation practice, valid statistical measures of the examined tooth characteristics are generated as reference data. Statistical bias ('age mimicry') and incorrect stage determinations are avoided by the even age distribution of the samples and the consensual stage determination by two experienced examiners. The questionable influence of ethnicity on the examined dental characteristics is clarified by age- and gender-matched samples of the main ethnic groups relevant for forensic age assessment (Europids, Asians, Africans) as well as by consensual stage determinations of identical experienced examiners. Systematic simulation studies are used to compare the statistical methods published by various research groups for the classification of pre-defined age limits and the combination of characteristics. As a result, the most suitable predictive model will be determined, which will lead to an increase in the reliability of the age diagnosis in the practice of forensic age assessment. The project is of great socio-political importance. The expected research results are also important for forensic age assessment in numerous other European countries in which the legally relevant age limits lie within the age range covered by the project.
