Determination of Age and Sex from Nail Lines

This study analyzes fingernail samples to investigate the relationship between age and longitudinal ridges, assessing their forensic significance. Samples from individuals aged 5 to 80 years were examined under a stereo microscope to observe ridge density and pattern variations. Results were evaluated to determine the applicability in forensic age estimation and identification. Different samples were tested and after clearly observing the different patterns in the nail result were analysed for determining the significance of nail patterns or nail lines in the determination of age.
