A bimanual comparison of variation in sweat pores with sex and age: a brief dermatoglyphic survey of population in Delhi-NCR
Personal identification using partial fingerprints poses a major challenge in forensic investigations. In light of such restrictions, sweat pore characteristics have shown to be a possible alternative. However, limited research has been done on these due to their minute size. The present study was undertaken with the objective of studying the differences in pore frequency, pore shapes (circular and non-circular), and pore positions (middle and periphery) with respect to sex, bimanual, and age in the population of Delhi-NCR (National Capital Region). As there is no universal approach for defining the evaluation area of pore analysis, we used fingerprint patterns to demarcate a 9mm2 area of analysis. The rolled-inked fingerprints of 200 individuals (100 males and 100 females) belonging to 18-60 years of age were examined using microscopy. The obtained data for all prints was analysed and compared with respect to the different variables. The results showed statistically significant bimanual variations for both sexes. In females, all studied pore characteristics except the number of pores at the middle position were significantly higher in the right hand as compared to the left hand. In males, only the number of pores at the peripheral position was significantly higher in the right hand as compared to the left hand. However, no significant differences were observed in pore characteristics between the two sexes and among the different age groups. Moreover, several pore characteristics showed a significant correlation with age in males as compared to females where no significant correlations were observed. Significant bimanual variations highlighted the potential application of pore characteristics for forensic practice; wherein a fingerprint examiner might determine the probable hand used for the commission of the crime, thereby strengthening the evidentiary value of partial fingerprints. These findings also suggest that the sex and age of an individual cannot be determined by pore characteristics.
