Abstract
Introduction: Saliva found on victims can be potentially recovered and typed from bite marks, cigarette butts, postage stamps, envelopes, edibles, and other objects. The detected saliva is recognized as one of the primary source of DNA by the forensic serologist. Aim: In this study, we have evaluated the quality of the salivary samples collected from porous (cloth and mud) and non-porous (cement and ceramic tile) surface for the number of cells obtained and their viability for the use of DNA extraction. Materials and Methods: Sixty samples of saliva were collected on non-porous tile and cement surface and porous cloth surface and saliva was collected at the interval of 2 and 5 days. The samples were collected, centrifuged, and analyzed with trypan blue staining. Results: There was a strong positive correlation between number of cells and viability of cells and the surface, which was statistically significant, rs = 0.726. Conclusion: Saliva is found to be an emerging forensic tool. It has found to be of great help in forensic by monitoring drug abuse, help in sex determination, and bite marks analysis which can be human and non-human. Saliva provides genetic material which can be used even if it is stored suboptimal.
