Abstract

Background: Analysis of fingerprints and palm prints at the crime scene is vital to identify the suspect and establish a crime.Dermatoglyphics can even be valuable in identification of a dismembered hand during medicolegal investigations to establishthe identity of an individual in cases of mass disasters/mass homicides. Methods: The present research studies the variation in ridge density in different areas of the palm prints among men andwomen. The four prominent areas were analysed on the palm prints that included central prominent part of the thenareminence (P1), hypothenar region; inner to the proximal axial triradius (P2), medial mount; proximal to the triradius of thesecond digit (P3) and lateral mount; proximal to the triradius of the fifth digit (P4). Results: The mean palm print ridge density was significantly higher among women than men in all the designated areas inboth hands except for the P3 area in the right hand. Statistically significant differences were observed in the palm print ridgedensity between the different palm areas in men and women in right and left hands. No significant right–left differences wereobserved in the palm print ridge density in any of the four areas of palm prints among men. In women, right-left differenceswere observed only in the P3 and P4 areas of palm prints. Conclusions: This preliminary study indicates that though the palm print ridge density is a sexually dimorphic variable, itsutility for estimation of sex in forensic identification may be limited owing to significant overlapping of values.
