doi:10.37506/ijfmt.v14i1.30

Abstract

Background: Identification of the suspect, living or dead with the help of physical charachteristics play a vital role in forensic science. Improved methods of gender determination and personal identification are important in solving criminal cases. Cheiloscopy and dactyloscopy have been proved to be of use in personal identification. The present study aims to evaluate correlation of Cheiloscopy and Dermatoglyphics in gender determinationMaterials and Method: The study was carried out from January 2017 to January 2019 on 2112 individuals (1056 males and 1056 females) aged from 15 to 60 years in KMCT Dental College, Calicut. For lip print analysis Suzuki and Tsuchihashi classification was followed. For finger print analysis impression of all the fingers were taken. For analysis, the images were cropped and abode photoshop software was used.Results: Type 1 and 1’ lip groove patterns were found to be predominant among males.Type 4 and Type 5 lip groove patterns were found to be predominant among females. Loop finger print patterns were found to be predominant among males.Whorl finger print patterns were found to be predominant among females. Positive correlation (+0.80) was found between loop finger print pattern and Type 1’ lip print pattern in males which is statistically significant (p=0.003).Positive correlation (+0.75) was found between whorl finger print pattern and Type IV lip groove pattern in females which is statistically significant. (p=0.005)Conclusion: There was definite correlation of Cheiloscopy and Dermatoglyphics in gender determination

Highlights

Forensic science plays a vital role in the identification of the suspected victim or victimizer of a crime, with the help of physical characteristics
Loop finger print patterns were found to be predominant among males.Whorl finger print patterns were found to be predominant among females (Table 3-6)
The current research revealed the predominance of Type IV,Type V patterns among females and Type I’, Type I patterns among males

Summary

Introduction

Forensic science plays a vital role in the identification of the suspected victim or victimizer of a crime, with the help of physical characteristics. Improved methods of gender determination and personal identification are gaining importance in recent years.[1,2]. The term “fingerprint” predominantly means an impression of the epidermal ridges of the fleshy distal portion of a finger. It was first given by Harold Cummins in the year 1926.[3]. Identification of the suspect, living or dead with the help of physical charachteristics play a vital role in forensic science. Improved methods of gender determination and personal identification are important in solving criminal cases. The present study aims to evaluate correlation of Cheiloscopy and Dermatoglyphics in gender determination
