Finger Print Ridge Density a Tool for Gender Determination
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 8
Abstract
Background: Fingerprints being unique to a human being, is a valuable tool in identification. Identification of sex from fingerprint ridge density has been attempted by earlier researchers. Objectives: The objective of the study was to determine ridge density of males and females and to identify whether sexual differences exist between them. Methodology: The study was conducted on 170 subjects [70 males and 100 females] in the age group of 18-65 years. Mean ridge density was calculated from the finger prints of the participants and were statistically analysed. Results: The results showed that in male subjects, the ridge density ranged from 8.0 to 12.90 ridges/25 mm2 with a mean of 10.62 ridges/25 mm2 [S.D - 1.02], and in females from 10.20 to 15.00 ridges/25 mm2 with a mean of 12.69 ridges/25 mm2 [S.D - 1.01]. Mean ridge density was higher in females than males. Fingerprint possessing > 13 ridges/25 mm2 has a higher probability of being from female (p = 0.99). The probability of fingerprint of < 11 ridges/25 mm2 of being from a male origin is very large. Conclusion: The study confirms that females have higher ridge density than males. Mean fingerprint ridge density of 12 ridges/25 mm2 or less is more likely to be of male origin and a mean ridge density of more than 13 ridges/25 mm2 is more likely of female origin.
