摘要

有效的参考数据对于可靠的法医年龄评估程序至关重要,这一事实也延伸到牙科全景X光片(PAN)中下颌第三磨牙的萌出特征。本研究的目的是获取中国北方人群的有效参考数据。研究以年龄评估参考研究的标准为指导。为此,研究人员分析了来自中国的研究人群,包括 430 名女性和 487 名男性的 917 张全景照片,年龄在 15.00 至 25.99 岁之间。在这 917 张全景照片中,共有 1230 颗下颌第三磨牙接受了评估。回顾性评估的全景照片是在 2016 年至 2021 年期间因医学指征而进行的。下颌第三磨牙的评估采用了Olze等人在2012年提出的分级标准。两名接受过法医年龄评估 PANs 培训的独立检查员对图像进行了评估。如果两位检查者的评估意见不一致,则会进行讨论,然后分配出一个一致同意的阶段。D 阶段表示牙齿完全萌出,女性的最低年龄为 15.6 岁,男性为 16.1 岁。因此,下颌第三磨牙的完全萌出在男女两性中均可观察到,远早于 18 岁。从我们的研究结果来看,仅靠评估下颌第三磨牙的萌出情况显然不足以准确判断成年年龄。与以往的文献相反,根据我们的结果,中国北方人下颌第三磨牙完全萌出的这一发现仅适用于检测男性是否已满 16 岁。然而,由于结果与其他文献中的研究结果不一致,因此不应将该特征作为证明中国北方男性这一年龄界限的唯一决定性标志。

Age-related patterns in mandibular third molar eruption: presenting new forensic age assessment reference data from a Chinese population.

Valid reference data are essential for reliable forensic age assessment procedures in the living, a fact that extends to the trait of mandibular third molar eruption in dental panoramic radiographs (PAN). The objective of this study was to acquire valid reference data for a northern Chinese population. The study was guided by the criteria for reference studies in age assessment.To this end, a study population from China comprising 917 panoramic radiographs obtained from 430 females and 487 males aged between 15.00 and 25.99 years was analysed. Of the 917 PANs, a total of 1230 mandibular third molars were evaluated.The PANs, retrospectively evaluated, were performed for medical indication during the period from 2016 to 2021. The assessment of mandibular third molars was conducted using the staging scale presented by Olze et al. in 2012. Two independent examiners, trained in assessing PANs for forensic age estimation, evaluated the images. In instances where the two examiners diverged in their assessments these were subsequently deliberated, and a consensus stage was assigned.The mean age increased with higher stages for both teeth and both sexes. The minimum age recorded for stage D, indicating complete tooth eruption, was 15.6 years in females and 16.1 years in males. Consequently, the completion of mandibular third molar eruption was observed in both sexes well before reaching the age of 18. In light of our results, it is evident that relying solely on the assessment of mandibular third molar eruption may not be sufficient for accurately determining the age of majority. Contrary to previous literature, this finding of a completed eruption of the mandibular third molars in northern Chinese individuals is only suitable for detecting the completion of the 16th year of life in males according to our results. However, as the results are inconsistent compared to other studies in the literature, the trait should not be used as the only decisive marker to prove this age threshold in males from northern China.

期刊介绍: Forensic Science, Medicine and Pathology encompasses all aspects of modern day forensics, equally applying to children or adults, either living or the deceased. This includes forensic science, medicine, nursing, and pathology, as well as toxicology, human identification, mass disasters/mass war graves, profiling, imaging, policing, wound assessment, sexual assault, anthropology, archeology, forensic search, entomology, botany, biology, veterinary pathology, and DNA. Forensic Science, Medicine, and Pathology presents a balance of forensic research and reviews from around the world to reflect modern advances through peer-reviewed papers, short communications, meeting proceedings and case reports.
