The present study evaluated the histopathological changes in oral tissues induced by pesticide poisoning. This was a cross-sectional pilot study. The sample consisted of oral tissues obtained from deceased patients during autopsy. The study samples were obtained from 10 cases of ingested pesticide poisoning, and the control samples were obtained from road traffic accident cases. All the obtained samples were subjected to histopathological examinations. The changes observed in poisoning cases were compared to those in the road traffic accident cases. Significant degenerative changes were observed in the epithelial cells and connective tissue components, such as collagen, muscles, nerves, vasculature, adipose tissue, and salivary acini and ducts, in the poisoning cases. The oral tissues of the road traffic accident cases did not show any significant degenerative changes. The degenerative changes in the study samples can be attributed to the direct contact of the pesticide with the autopsied oral tissues when the poison was consumed. There are instances in which the entire body may not be recovered or may not be in an examinable state. In such cases, an oral autopsy could provide additional evidence for determining the cause of death in suspected poison cases.
