This meta-analysis addresses the use of mandibular computed tomography (CT) scans for age and/or sex determination in forensic science.
Six databases were searched until June 2023, using the keyword "mandible" combined with keywords related to "multislice computed tomography" (MCT) or "cone-beam computed tomography" (CBCT) and keywords related to "skeletal age determination" or "sex determination analysis."
Among the 23 studies included, 11 used MCT and 12 used CBCT to perform forensic assessments. Age determination was the aim of a single study, sex and agedeterminations were the objective of five studies, and the other studies investigated the determination of sex only. Metaanalysis could be performed only for sex determination.
Mandible measurements are useful in sex determination, as the bicondylar and bigonial breadth are larger in males than in females. For the mandible angle, the meta-analysis results confirm sex dimorphism in CBCT scans but not in MCT scans. For age estimation, further studies are needed to prove that the mandible hole is a reliable parameter for age estimation. PROSPERO registration number: CRD42021260967.
本荟萃分析探讨了下颌骨计算机断层扫描（CT）在法医学中用于年龄和/或性别鉴定的应用。
截至 2023 年 6 月，使用“下颌骨”一词与与多排 CT（MCT）或锥形束 CT（CBCT）相关的关键词以及与骨骼年龄鉴定或性别鉴定分析相关的关键词相结合，在六个数据库中进行了搜索。
在纳入的 23 项研究中，11 项使用 MCT，12 项使用 CBCT 进行法医评估。一项研究旨在进行年龄鉴定，五项研究的目的是进行性别和年龄鉴定，其他研究仅调查了性别鉴定。仅能对性别鉴定进行荟萃分析。
下颌骨测量值在性别鉴定中很有用，因为髁突间和髁突间宽度男性大于女性。对于下颌角，荟萃分析结果证实了 CBCT 扫描中的性别二态性，但在 MCT 扫描中没有。对于年龄估计，需要进一步的研究来证明下颌骨孔是可靠的年龄估计参数。PROSPERO 注册号：CRD42021260967。
