“…Similar, to our finding predominance of Type II lip print was observed by Karki in Nepalese population, Verma et al, Patel et al and Gondivkar et al in Indian population. 10,17,18,19 In contrary study findings of Ghimire et al In females distribution of lip prints was in order Type II (75.00%)>Type I' (9.00%)>Type IV (7.00%)>Type I (5.50%)>Type III (3.50%) with no Type V (0.00%). This is in accordance to the results of various studies done earlier which reveals that lip prints show ethnic and racial differences thus, it can be a suitable adjunct to identification of the person.…”

“…As suggested by several authors a common problem encountered with traditional lip stick method is smudging or spoiling of lip prints leading to unidentifiable marks. 10,11 Also, the amount and evenness, pressure and direction of the lipstick applied to the lips can disturb the accuracy of the records as well. 12 Thus, in this study an easier photographic method with nil physical contact as adopted by Kapoor & Badiye 13 in Indian population is applied.…”

Background: Lip prints are considered as very useful and are to be important forms of transfer evidence like finger prints. Studies have shown that even lip prints are unique for an individual and hence have the potential for personal identification. Aims and Objectives: To correlate the distribution of lip print pattern and its gender wise predominance. Material and Methods: The study comprised of 100 Nepalese medical students (50 males; 50 females). A photographic method was adopted rather than the old traditional lipstick method. The photographed lip prints were transferred into a computer to identify the character/lip print pattern. Statistical analysis was done using the SPSS (version 23.0) software package and Chi-square test was applied to evaluate the existence of correlation of lip print pattern with gender. Results: Type- II lip print pattern was frequently observed in all the four quadrants of both the sexes. This was followed by in order Type-I’>Type-I> Type-IV and Type-III lip patterns. There was a difference in gender wise distribution of lip prints. Conclusion: Further specific population based and gender specific studies on lip prints with larger sample size are required for comparison of lip prints with gender, so that a database could be created and used for representing sex differentiation.

BackgroundLip prints are verified to be unique to an individual and stable over time; hence they have potential for human identification purposes. The aim of this study was to assess the individuality and variability of lip prints in an Iranian population for the first time. We also sought to assess the possibility of sex determination via lip printing.Material and MethodsLip prints of 96 individuals including 22 males and 74 females were recorded on a plain white paper using a dark-colored lipstick and 50 mm of Scotch tape. Each lip print was divided into six sextants and studied independently by two observers using a magnifying lens to examine the lip grooves. The Suzuki and Tsuchihashi’s classification was used to define the lip patterns and the data were statistically analyzed.ResultsIn the present study, no identically similar lip prints were observed. Type V was the most predominant pattern recorded in the study sample (33.16%), followed by type I (24.13%), type II (18.75%), type IV (11.63%), type I’ (9.72%) and type III (2.60%). In addition, no statistically significant difference was observed in the lip print patterns of males and females.ConclusionsIt can be concluded that lip prints are unique and their analysis may enable human identification. Key words:Forensic anthropology, forensic dentistry, forensic medicine, iran, lip.

“…Another study among Nepalese medical students too revealed comparable findings which stated, Type V was rare while Type I (38%) was leading among male and Type II (42.5%) among female. 9 Mishra et al showed, Type III (42%), Type II (24%) and Type IV (12%, 20%) to be the most and least common in both male and female respectively. 13 A study from Libya, on the other hand revealed the commonest lip print pattern to be Type I in 53.37% males and 60.07% females, while Type I to be the least.…”

Introduction: Lip prints, due to their unique patterns are typical to an individual, hence, used for personal identification. They vary in predominance, gender and race among different populations. The objective is to study their distribution among medical students and identify the predominant type. Methods:The descriptive cross-sectional study was conducted on the medical students of Nepalese Army Institute of Health Sciences, from April 2019 to May 2019 after the ethical approval. Convenience sampling was used. The prints were classified according to Suzuki and Tsuchihashi. The collected data was entered in SPSS to determine the frequency and percentage. Sub group analysis was done on basis of gender and types of lip print. Results:Out of 205 participants, prevalence of type I lip print among medical students is 70 (34.1%). Type I lip print was found to be most common followed by Type II in 57 (27.8%) and Type V in 6 (2.9%). One hundred forty one (68.8%) were male and 64 (31.2%) were female. The predominating pattern in RUQ; LUQ; LLQ; RLQ among male and female is Type I 46 (32.6%) and Type I 39 (27.7%); Type II 39 (27.7%) and Type II 44 (31.2%); Type I 19 (29.7%) and Type II 19 (29.7%); Type I 31 (48.4%) and Type I 27 (42.2%) respectively. Conclusions:Type I was the most common while Type V was the least common lip print. However, there was variation in its frequency and distribution according to the quadrant and sex. ________________________________________________________________________________________
