Improved methods of gender determination and personal identifcation are important in solving criminal cases. Cheiloscopy and dactyloscopy have been proved to be of use in personal identifcation. The present study aims to evaluate correlation of Cheiloscopy and Dermatoglyphics in gender determination Materials 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 classifcation was followed. For fnger print analysis impression of all the fngers 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 fnger print patterns were found to be predominant among males.Whorl fnger print patterns were found to be predominant among females. Positive correlation (+0.80) was found between loop fnger print pattern and Type 1’ lip print pattern in males which is statistically signifcant (p=0.003).Positive correlation (+0.75) was found between whorl fnger print pattern and Type IV lip groove pattern in females which is statistically signifcant. (p=0.005) Conclusion: There was defnite correlation of Cheiloscopy and Dermatoglyphics in gender determination Keywords: Cheiloscopy, Dermatoglyphics, Gender determination. Introduction Forensic science plays a vital role in the identifcation of the suspected victim or victimizer of a crime, with the help of physical characteristics. Physical evidence is important to solve criminal cases. Improved methods of gender determination and personal identifcation are gaining importance in recent years. [1,2] Lip patterns and fnger print patterns remain the same throughout life and are uninfuenced by environmental changes and diseases. Cheiloscopy is a forensic investigation technique that deals with identifcation of humans based on lip traces. A lip print at a crime scene would throw light on many areas of the investigation like the number of people involved, the gender and the behavior pattern of the crime. Edmord locard was the frst scientist to recommend the use of lip prints in personal identifcation. [1] Dermatoglyphics is the term specifed to the scientifc study of fngerprints. The term “fngerprint” predominantly means an impression of the epidermal ridges of the feshy distal portion of a fnger. It was frst given by Harold Cummins in the year 1926. [3] Cheiloscopy and dactyloscopy are used in personal identifcation.
