Cambios Histológicos en el tejido gingival post- mortem en las primeras 24 horas.

The current research project aims to determine the histological changes in the gingival tissue during the first 24 hours postmortem. Therefore, it was necessary to carry out a scientific bibliographic review of the literature according to the recommendations of the methodology. Identifying and determining that changes in epithelial tissue include loss of epithelial architecture, chromatin agglomeration, nuclear vacuolation, and epithelial homogenization; these changes are observed at different time intervals after death, such as immediate, one h, five h, 24 h, and 48 h. On the other hand, finding the changes in the connective tissue in myofibrillar degeneration is possible. It is vital to know that separating epithelium and connective tissue is a significant change that could occur at later postmortem intervals, typically after 24 hours. The enzymatic changes in the gingiva are in two different phases: the first phase becoming present is the autolytic phase, in which it is possible to find the enzyme acid phosphatase decreasing its levels when the time intervals increase. On the other hand, the second phase is present, which is the putrefaction phase. It is characterized by the release and rise in ammonia levels over time; these enzymatic and histological changes have been considered a useful consensus to estimate the time interval (PMI).
