“…11 L H Adamu et al, concluded that type V lip prints was predominant in a study done in Nigerian population. 9 In our study, type I lip prints was found to be predominant in males and type II in females. In the percentage distribution of lip prints the variation noticed with respect to other previous studies may be linked to genetic influences which vary with respect to different races.…”

BACKGROUND AND OBJECTIVE: The use of conventional methods such as dactylography (study of finger prints) & cheiloscopy (study of lip prints) is of paramount importance, since personal identification by other means such as DNA analysis is sophisticated and not available in rural and developing countries. Fingerprint in its narrow sense is an impression left by the friction ridges of human fingers. The second prints of interest are lip prints. Studies of association between finger print and lip prints are scanty in literature. The present study was aimed to analyze the predominant pattern of lip and finger prints and to identify whether there is any correlation between these two parameters. MATERIALS AND METHODS: The study sample included 300 college students. Brown/pink colored lip stick was applied on the lips and the subject was asked to spread it uniformly over the lips by gentle movement of the lips. The unglazed white paper was then pressed uniformly over the lips. After the fingers were cleaned with tissue paper, the subjects were instructed to roll the tip of their fingers across the surface of an already made ink-stained pad, ensuring that the ink covered the entire pattern area. The inked finger was then enrolled over a white paper to obtain the print and analyzed using magnified hand lens. These prints were examined using magnifying glass, classified, and analyzed. The data was statistically analyzed by using Chi-square test. RESULTS: The percentage distribution of lip print shows that the most frequent lip print pattern in the male is Type I (36.8%) and in female it is type II (34.4%). There is no statistically significant association between the pattern of finger prints and lip prints (p value = 0.9). CONCLUSION: It is known that individual parameters, i.e., lip print and finger print patterns play an important role in forensic identification. Correlation of these two parameters in our study did not show any significant association, hence, these combinations as such cannot be used in individual identification, but rather, they can be used to substantiate facts in crimes where there are few evidences

“…It was reported that there is inheritance of lip prints in cleft lip and cleft plate in children (Weal et al, 2005). The sexual dimorphic trait reported in lip prints were also associated with genetic influences which vary with respect to different sexes more importantly in sex chromosomes (Adamu et al, 2012).…”

Background: Lip prints can be used in crime investigation to establish the presence of a victim or a suspect at a crime scene since they are visible with the naked eye but latent prints are not visible with naked eyes. The examination of these features is called cheiloscopy. Cheiloscopy or Quiloscopy is simply the study of the patterns produced by the lip prints and their application. Aim: This study was aimed at investigating the association between lip prints types and gender and the proportionality difference in distribution of lip prints between male and female. This study will add to the body of knowledge information on the association of gender and lip print which will be beneficial to geneticists, forensic experts, biologists and everyone who has interest in security outfits. Materials and Methods: A cross-sectional study design with 450 volunteers. Volunteer subjects were conveniently selected from across Port Harcourt Metropolis. Results and Discussions: This study suggest that lip distribution is independent of the gender and what was seen in the upper right quadrant (URQ) could be by a coincidence and not strong enough to suggest that lip print distribution is dependent on gender. Conclusion: The findings of this study suggest that Type I is the most predominant lip print type, followed by Type II among the study population. The study showed that not all quadrants exhibited gender differences in the pattern of lip prints distribution. Only a one quadrant (Upper Right Quadrant) of lip prints can be said to have gender discriminatory indicators, and this maybe a mere coincidence. Thus, suggests that lip prints may not be a good predictive tool for gender.
