The pore characteristics on the epidermal friction ridges are individualistic and thereby useful in the process of identification when used along with other minutiae details. The present work was undertaken with the objective of studying the sex difference and influence of age on the pore morphology. The study included 230 Indians belonging to various age groups. There was no significant difference in the pore characteristics between both the sexes. The average number of pores per centimeter of friction ridge was 8.40 in males and 8.83 in females. The closed type was the commonest type of pores seen. The size of pores varied from 69 μm to 284 μm in males and 66 μm-287 μm in females. The medium-sized pores were more common than the small and large-sized pores. The majority of the pores were situated in the periphery of the ridge. The commonest shape of pores seen was circular and oval shaped pores. As the age advances, the number of pores does not significantly vary. But, the size gradually increases, and the position and shape of pores changes with the age.
