摘要

估算死后间隔时间(PMI)是法医调查的重要步骤,尤其是涉及凶杀案和无证人死亡的调查。然而,传统方法偶尔会产生不一致的估计结果。组织学和分子技术被认为是法医病理学的关键,经常被用来估计死亡时间间隔。牙龈是用于估计 PMI 的口腔黏膜组织。本综述旨在研究利用口腔黏膜组织(即牙龈)确定 PMI 的组织学方法的潜力,并研究口腔黏膜组织与正常组织相比在不同时间间隔内发生的变化。口腔黏膜由分层鳞状上皮和结缔组织组成。与身体其他组织类似,已知牙龈在死亡后也会发生变化,这些细胞和组织变化也应考虑在内。牙龈的变化包括:均质化、核分裂、热解、核溶解、染色质结块、嗜酸性粒细胞增多、胶原纤维降解和组织结构丧失。整理原始试验结果的综述一致报告了自溶如何改变口腔黏膜,以及如何在死后的组织形态学中观察到这些变化。组织学是一种可接受的准确估算 PMI 的技术。

Histogical changes in oral mucosa (gingiva) as a method for estimating post-mortem interval: A literature review

Estimating the post-mortem interval (PMI) is an essential step in forensic investigations, particularly those involving homicides and unwitnessed deaths. However, traditional methods occasionally yield inconsistent estimates. Histological and molecular techniques are considered crucial in forensic pathology and are frequently employed to estimate the time interval of death. The gingiva is an oral mucosal tissue used to estimate PMI. This review aimed to examine the potential of histological methods to determine PMI using oral mucosal tissue, namely the gingiva, and to investigate changes that occur in oral mucosal tissue at different time intervals when compared with those in normal tissues. The oral mucosa comprises layers of stratified squamous epithelium and connective tissue. Similar to other body tissues, changes are known to occur in the gingiva after death, and these cellular and tissue changes should also be considered. Alterations in the gingiva include homogenisation, karyorrhexis, pyknosis, karyolysis, chromatin clumping, eosinophilia, collagen fibre degradation, and the loss of tissue architecture. Reviews collating the results of original trials have consistently reported how the oral mucosa is altered by autolysis and how such changes can be observed in histological tissue morphology after death. Histology is an acceptably accurate technique for estimating PMIs.
