Abstract

Bite mark analysis is among the most interesting research fields in forensic odontology; however, it is limited by its dependence on the employed method as well as assessor subjectivity, particularly when using morphological analysis or DNA profiling. These limitations are due to differences in DNA collected from saliva adhering to a living or inanimate body, as well as differences in exocrine fluid secretion and deposition amount among individuals. This study aimed to analyze the effectiveness of DNA profiling when there are differences in the amount of saliva adhering to a living body and when time has elapsed since deposition. Most allele peaks could be identified in 1 µl of saliva, even 9 h after saliva deposition and examination. Consistent results were obtained following saliva deposition in an individual who had engaged in up to 9 h of free activity. The results of this study demonstrate the validity and reliability of DNA profiling for bite mark analysis and are extremely important as they can demonstrate the usefulness of the little information left by a suspect on a victim's body.

唾液沉积量和沉积后经过的时间对咬痕分析的影响。
咬痕分析是法医牙学中最有趣的研究领域之一;然而,它受到所用方法的依赖性以及评估者主观性的限制,特别是在使用形态学分析或DNA图谱时。这些限制是由于从附着在活体或无生命体上的唾液中收集的DNA的差异,以及个体之间外分泌液分泌和沉积量的差异。这项研究旨在分析当附着在活体上的唾液量存在差异时,以及当沉积后经过一段时间时,DNA图谱的有效性。大多数等位基因峰可以在1µl唾液中识别,甚至在唾液沉积和检查后9小时。在进行长达9小时的自由活动的个体的唾液沉积后,获得了一致的结果。这项研究的结果证明了DNA图谱用于咬痕分析的有效性和可靠性,并且非常重要,因为它们可以证明嫌疑人在受害者身上留下的少量信息的有用性。
