Introduction: Dermatoglyphics has a potential contribution to biological anthropology and population genetics. The present study aims to detect the percentages of dermal ridge patterns’ distribution among both sexes of medical students of Beirut Arab University with the intent to provide data that can serve as a control group in the future dermatoglyphic studies.

Materials and Methods: 50 males and 50 females of Lebanese medical students were taken randomly from all students of faculty of medicine of Beirut Arab University.

Results: The total distributions of fingertip patterns for both hands were 9.4 % for arches, 44.4 % for ulnar loops, 6.2 % for radial loops and 40.0 % for whorls for male students, 8.6 % for arches, 46.4 % for ulnar loops, 6.6 % for radial loops 38.4 % for whorls for females. Radial loops had the least distribution among both hands of males with nearly equal distribution between the ten fingers. Same results were found in both hands of females, with more inclination to the left index. For the palmar dermatoglyphic, the mean atd angle in males was 44.6 ± 5.795847 for the right hand and 45 ± 6.586938 for the left hand with no significant difference. In females it was 44.94 ± 4.528414 for the right hand and 46.14± 7.056651 for the left hand with no significant difference. The results for the Pattern intensity index was 13.02 for both sexes, for the Dankmeijer’s index was 22.959 for both sexes and for the Furuhata’s index was 75.676 for both sexes. More than 3 fingers’ were concordant in the present work in both sexes 80 %.

Conclusion: For finger tips, loops had the highest ratios, arches were the least, and whorls were in between with no significant differences between both hands and in both sexes. In the palm, the mean atd angle was around 45o for both hands and in both sexes.
