BACKGROUND/AIM: Orofacial trauma and traumatic dental injuries (TDI) are serious public health problems due to their high prevalence, severe morbidity, high costs of treatment, and long-term sequelae. However, the extent of the problem may be underestimated since trauma analysis, from a forensic odontology perspective, is not widely represented in the scientific literature. The aim of this study was to investigate the occurrence of traumatic orofacial injuries (TOI) and TDI in unidentified bodies and their association with the cause of death.
A retrospective analysis was conducted of dental and autopsy reports of unidentified bodies admitted to the Institute of Forensic Medicine of Belo Horizonte (IFM-BH), Brazil, between 2015 and 2016. The final sample was made up of 536 bodies. Demographic data, the location where the body was found, cause of death, and the presence and type of orofacial trauma were collected.
The mean of the estimated age of the bodies was 38 years and the median was 35 years. Most of the bodies were from males (87.5%) and were found downtown in the city of Belo Horizonte (60.4%). Violence was the most common cause of death (64%), generally by gunshot (48.7%). Bodies with an estimated age ≤35 years were eight times more likely to have died from violent causes. TOI was registered in 50.9% of the reports. TDI was observed in 10.8% of the bodies. Victims of violent death were seven times more likely to present TOI. Such association was not observed when the presence of TDI was considered.
There is a positive association between TOI and violent death in unidentified bodies.
背景/目的：口腔颌面部创伤和外伤性牙损伤（TDI）是严重的公共卫生问题，因为它们的发病率高、发病率严重、治疗费用高和长期后遗症。然而，由于法医牙科学角度的创伤分析在科学文献中没有得到广泛体现，因此问题的严重程度可能被低估了。本研究旨在调查不明身份尸体中创伤性口腔颌面部损伤（TOI）和 TDI 的发生情况及其与死因的关系。
对 2015 年至 2016 年期间送入巴西贝洛奥里藏特法医研究所（IFM-BH）的不明身份尸体的牙科和尸检报告进行了回顾性分析。最终样本由 536 具尸体组成。收集了人口统计学数据、发现尸体的地点、死因以及口腔颌面部创伤的存在和类型。
尸体估计年龄的平均值为 38 岁，中位数为 35 岁。大多数尸体来自男性（87.5%），发现于贝洛奥里藏特市市区（60.4%）。暴力是最常见的死因（64%），通常是枪伤（48.7%）。估计年龄≤35 岁的尸体死于暴力原因的可能性高出八倍。50.9%的报告中记录了 TOI。10.8%的尸体观察到 TDI。死于暴力的受害者发生 TOI 的可能性是其七倍。当考虑 TDI 的存在时，未观察到这种关联。
在不明身份的尸体中，TOI 与暴力死亡之间存在正相关关系。
