A Relative Study of Finger nail plate Shape among Indian PopulationDownload PDF
Introduction-Finger-nail features are considered as distinct and the study of nail anatomy reveals that only the nail plate is regenerated as new cells are made, the spacing between the grooves of the nail bed remains constant over the entire life of the individual. Thus, unlike face characteristics which changes with the age of an individual, the characteristics of the nail bed imitated on the nail plate can be very useful for identification over the entire lifespan of an individual. Objectives-Due to the immense potential of fingerprints as well as nail plate pattern as an effective method of identification an attempt has been made in the present work to analyze different finger nail plate pattern existing among human population. Sampling and Methodology -The study was conducted on 100 subjects above age group of 18years. Fingernail shape were collected and analyzed. Result- Experiment shows that males and females tend to have rectangular pattern in thumb. On index, middle and ring finger, triangular pattern dominates in both males as well as females whereas in case of little finger the pattern varies. The nail patterns on right hand repeats in left hand of an individual or vice versa. Conclusion-Fingernail plate shapes of hands show diversities similar to fingerprint and therefore can be utilized for identification.
