Abstract

Establishing the human dental identification process relies upon sufficient post-mortem data being recovered to allow for a meaningful comparison with ante-mortem records of the deceased person. Teeth are the most indestructible components of the human body and are structurally unique in their composition. They possess the highest resistance to most environmental effects like fire, desiccation, decomposition and prolonged immersion. In most natural as well as man-made disasters, teeth may provide the only means of positive identification of an otherwise unrecognizable body. It is imperative that dental evidence should not be destroyed through erroneous handling until appropriate radiographs, photographs, or impressions can be fabricated. Proper methods of physical stabilization of incinerated human dental remains should be followed. The maintenance of integrity of extremely fragile structures is crucial to the successful confirmation of identity. In such situations, the forensic dentist must stabilise these teeth before the fragile remains are transported to the mortuary to ensure preservation of possibly vital identification evidence. Thus, while dealing with any incinerated dental remains, a systematic approach must be followed through each stage of evaluation of incinerated dental remains to prevent the loss of potential dental evidence. This paper presents a composite review of various studies on incinerated human dental remains and discusses their impact on the process of human identification and suggests a step by step approach.

摘要

建立人类牙齿识别程序依赖于获取足够的死后数据,以便与死者的生前记录进行有意义的比对。牙齿是人体中最不易毁坏的部分,其结构组成独特。它们对大多数环境影响(如火灾、干燥、腐烂和长时间浸泡)具有最高的抵抗力。在大多数自然和人为灾难中,牙齿可能是识别面目全非尸体的唯一可靠手段。在制作适当的X光片、照片或印模之前,绝不能因错误处理而毁坏牙齿证据。应遵循对焚烧后的人类牙齿遗骸进行物理固定的正确方法。保持极其脆弱结构的完整性对于成功确认身份至关重要。在这种情况下,法医牙医必须在将脆弱的遗骸运往停尸房之前对这些牙齿进行固定,以确保可能至关重要的身份识别证据得以保存。因此,在处理任何焚烧后的牙齿遗骸时,必须在对焚烧后的牙齿遗骸进行评估的每个阶段都遵循系统的方法,以防止潜在牙齿证据的丢失。本文对关于焚烧后的人类牙齿遗骸的各种研究进行了综合综述,讨论了它们对人类身份识别过程的影响,并提出了一个逐步的方法。
