| Abstract | | The analysis of dermal ridges and their configuration on fingertips has been of considerable interest due
to their inimitable, permanent and unique characteristics. The present cross-sectional study is an attempt to assess
sex as well as topological differences in fingerprint ridge density among adult population of Nahan, Himachal Pradesh,
North India. The data comprised of 240 subjects (120 males and 120 females), aged between 18 to 24 years. The
results obtained in the study revealed significantly (p<0.001) higher fingerprint ridge density in females than males
at radial, ulnar and proximal topological areas. Both the sexes revealed a disto-proximal gradient of fingerprint ridge
density i.e proximal < ulnar < radial in both the hands. In regard to radial area fingerprint ridge density of ≤11 ridges
and ≥13 ridges had more possibility of male and female origin respectively. Fingerprint ridge density of ≤11 ridges and
≥12 ridges was more likely of male and female origin respectively in the ulnar regions. In proximal region, fingerprint
ridge density of ≤8 ridges and fingerprint ridge density of ≥10 ridges had more probability of being male and female
origin respectively. Results of discriminant function analysis further strengthen the conclusion of significant gender
differences in the ridge density at all the counting areas, thereby confirming fingerprint ridge density as a potential
tool for sex distinction. | | | | Keywords | | Fingerprint – Ridge density – Sex differences – Topological zones | | | | DOI | | https://doi.org/10.26720/anthro.19.04.17.2 | | |
