Aims and Objectives: The aim of the study was to evaluate and compare lip prints and palatal rugae pattern in Kerala, Karnataka, and Manipuri population. Materials and Methods: The study involved 180 individuals (60 each from Karnataka, Kerala, and Manipuri population). Lipstick was used to record lip prints, which were visualized by magnifying lens. Palatal rugae were recorded on maxillary casts of all subjects and analyzed following Kapali S et al.' s classification. Statistical Package for the Social Sciences version 20 for Windows software was used for analysis. Results: Among the study population, most frequent lip print pattern was Type 3 and least was Type 1'. When patterns were compared between groups, Type 3 was the most common in Manipuri and Kerala and Type 3 in Karnataka groups. In the entire population, males showed Type 3 and females showed Type 1. On analysis of overall rugae wavy, forward and divergence patterns were predominant. On comparison of gender, males demonstrated greater number of wavy and perpendicular rugae, and females had curved, straight, forward, and backward. Conclusion: Both cheiloscopy and rugoscopy have the prospective to recognize an individual. Cheiloscopy is more reliable than rugoscopy in making out the group and gender of an individual.

Background and objectives: Human identification is based on scientific principles, mainly involving estimation of age, sex, fingerprints, measurement of height, dental records. Just like these methods, lip prints can also be instrumental in identifying the sex which is vital for establishing the identity of an individual. The study of lip prints is known as cheiloscopy. The main objective of study was to find out accuracy of sex determination through lip prints. Method: The study was conducted on 2nd, 3rd and 4th year students of Azeezia medical college, Kollam. Subjects were 100 males and 100 females of the state of Kerala, aged between 18 and 25years. Details of the study were explained to the subjects and lip prints taken and analysed as per the Classification given by Tsuchihashi. Results: Type I was the most common lip print in total subjects and males. Type III predominated in females. Type I, I', II constituted majority of females. Type III, IV, V predominated in males. Conclusion: The results obtained in our study do not prove it to be an infallible method. But it still seems to open a small window to a vast unventured field. The need of the hour is to develop a standardized method to assess and accurately record the cheiloscopic patterns. [ABSTRACT FROM AUTHOR]

Background: Forensic dentistry, a branch of forensic sciences, identify suspects with the uniqueness of oral and maxillofacial structures. Lip prints and palmprints are unique. Aims and objectives: The present study was carried out with the objectives of evaluating the correlation between lip prints and palmprints and heritability of lip prints and palmprints among parents and their off springs. The predominant pattern of lip prints and palmprints were also analyzed. Materials and methods: The study group comprised of 35 families from South Kerala population. Participants belonging to the same family pedigree--Father, mother, children of each family were selected. Results: The predominant lip pattern in the entire study population was Type II. The predominant palm pattern in the entire study population was Category 5 in both right and left palm. Lip pattern shows a positive correlation with right palm pattern, but it is statistically insignificant (p = 0.144). Lip pattern showed neither positive correlation nor significant association with the left palm. This study results revealed significant association between lip print patterns among parents and children (p = 0.04). Conclusion: The present study was conducted to find out the heritability and correlation of lip and palmprints in the South Kerala population. Lip pattern shows a positive correlation with right palm pattern, but it is statistically insignificant. Significant association between lip print patterns among parents and children were noticed in our study. [ABSTRACT FROM AUTHOR]

Background: The study of lip-print pattern (cheiloscopy) is a scientific method for personal identification and plays a major role in forensic and criminal investigations. Objective: To compare the lip print patterns in Kerala and Maharashtra population and correlate between ABO blood groups. Materials and Methods: Two hundred subjects, 100 from Maharashtra and 100 from Kerala were considered for the study. Lip prints were recorded, analyzed according to Tsuchihashi classification. The lip print patterns were compared in the two populations, correlated in ABO blood groups. The data obtained was statistically analyzed with SPSS software using chi-square test. Results: In our study, predominant lip print pattern observed in Kerala population was type IV (53%) and Maharashtra population was type II (42%). The difference between the two population was statistically significant (p<0.001). Subjects with A+ and O- blood groups had type II lip print predominance. Subjects with B+, AB+ and 0+ blood groups had type IV predominance. The lip print patterns do not show any correlation in ABO blood groups. Conclusion: Lip prints are unique to each individual and are different even in two persons. Lip print patterns were different in the two sub populations studied, and they showed no correlation in ABO blood groups. [ABSTRACT FROM AUTHOR]
