Estimation of time since death is the preliminary step in any postmortem examination. Although there are various physiological methods to conclude the postmortem, interval histological changes can be applied to obtain precision. However, the utility of oral tissues for such an event is still evolving.
The present study was conducted to assess the efficacy of postmortem histological changes that occur in tongue to conclude the postmortem interval (PMI).
After obtaining institutional human ethical committee, tongue tissue was collected for during routine autopsy procedure. The study comprised twelve autopsied tongue tissues. The tissue specimens were subjected to routine laboratory tissue processing procedure and the histological changes were evaluated.
This is the first study of this kind in the scientific literature to explore the tongue tissue to estimate the PMI. There were definite changes in the epithelium and the connective tissue of the tongue, and these features were highly remarkable at various postmortem time intervals.
死亡时间的估计是任何尸体检验的初步步骤。尽管有多种生理方法来确定死后情况，但组织学变化可用于提高准确性。然而，口腔组织在此类事件中的应用仍在不断发展。
本研究旨在评估舌部发生的死后组织学变化在推断死后间隔时间（PMI）方面的有效性。
获得机构人类伦理委员会批准后，在常规尸检过程中收集舌组织。该研究包括12个经尸检的舌组织。组织标本经过常规实验室组织处理程序，并对组织学变化进行评估。
这是科学文献中首次探索利用舌组织估计PMI的此类研究。舌的上皮和结缔组织有明确变化，且这些特征在不同死后时间间隔非常显著。
