Digital dermatoglyphics has been found useful in forensic medicine and identification purposes. It is useful in medical diagnosis of genetically inherited diseases and in detection of crimes. Anthropometric studies of the digit, palm and feet provides data that reveal the relative distribution of dermal ridges among people in different geographical zones. Cross-sectional study was carried out using 100 males and 100 female healthy students of Kalinga Institute of Medical Sciences (KIMS) in Odisha State of India to establish their digital dermatoglyphics traits. This was done by counting and classifying their ridge pattern configurations of arches, loops and whorls and by counting their ridge densities/25mm. 2 Plain arches were the most predominant digital pattern in females (31%) than in males (10%), followed by loops (38%) in males than (28.5%) in females. The sex differences between these patterns are significant. Sexual dimorphism was also evident with the males≤11/25mm 2 showing lower in finger ridge count than the females 12/25mm 2 . This study has established on the normal dermatoglyphics patterns of medical students of KIMS in Orissa State of India. KEYWORDS: Dermatoglyphics, Ridge density, Pattern frequency, Pattern intensity, Sex difference. INTRODUCTION:Many human body features have been used to identify the sex of an individual. Due to their uniqueness and immutability, fingerprints are also one of the most commonly employed biometric features. Fingerprints of an individual have been used as one of the vital parts of identification in both civil and criminal cases because of their unique properties of absolute identity. Fingerprints have become increasingly popular for personal identification and verification in applications including banking security and physical access control. In addition to their value in criminal matters, fingerprints can ensure personal identification for humanitarian reasons, such as in cases of amnesia, missing persons, or unknown deceased. Fingerprints are invaluable in effecting identifications in tragedies such as fire, flood, and vehicle crashes. Digital dermatoglyphics has been found useful in forensic medicine and identification purposes. It is useful in medical diagnosis of genetically inherited diseases and in detection of crimes. Finger ridges and ridge patterns are highly heritable, durable, and age-independent human traits and have been studied as a model quantitative trait in humans for over the years. They develop between approximately the 13th and 18th weeks of gestation, and in the absence of trauma remain essentially unchanged throughout life. Despite many well developed fingerprint matching techniques and a wide range of biometric applications, a reliable fingerprint based sex determination method does not seem to be available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
