“…Various studies carried out in India, done by Sivapathasundarum et al [10] , Govindkar [11] , and Saraswathi [12] , showed type-III as predominant type whereas studies by Sharma et al [13] and Verghese et al [14] showed type-IV as predominant type. The result of the present study coincides with other studies [15,16,17] done in the past. This variation in prevalence can be explained by the ethnic and racial differences of the several cohorts studied.…”

Objectives: To determine the predominant lip print type in the Bihar population of India. Methods: In this cross -sectional study, 200 subjects of both sex (100 males and 100 females) aged between 25-40 years whose family origins were from Bihar were studied. Young adults without any disease related to lips, with normal lip mucosa were included in the study. The present study evaluates the pattern of lip print patterns among males and females and the findings of the study are compared with the available data. Results: Out of the 200 lipprint patterns studied, Type I (34.5%) were the most common pattern followed by Type IV (26%) and Type V (4%) being the least common pattern. In males, Type IV, Type I and Type II were 44 %, 27% and 3% respectively while in females Type I were 42%, Type I' were 24% and Type V were 4%. Conclusions: No two individuals have similar lip print impressions. Lip prints are unique to individuals and may help in personal identification. Further studies with larger sample size are required to establish that lip prints are unique like finger prints and can be used as a tool for identification in medicolegal cases.

“…Type V (undermined) was the least observed in both tribes and sex. Similar findings were reported by several studies (Manal et al, 2016 ; Neo et al, 2012 ; Rao & Kiran, 2016 ). However, Bindal et al ( 2014 ) reported contrarily on Indian population with the same Tsuchihashi classification.…”

Introduction Lip print of an individual is distinct and could be a useful form of evidence to identify the ethnicity of a terrorist. Objectives The study analyzed the distribution of lip print patterns of two major ethnic groups in Nigeria; Ibo and Hausa, to develop a strategic plan to check the wave of ethnically driven terrorism in Nigeria, carried out by groups such as Boko Haram and Indigeneous People of Biafra (IPOB). Materials and methods The study comprised 800 participants of Ibo and Hausa ethnic groups (400 males and 400 females). The study adopted a digital method of lip print analysis and followed the guidelines outlined by the Institute of Medicine (IOM) for anthropometric measurements. The lip was classified, using Tsuchihashi and Suzuki method of classification. Results The predominant lip print patterns of Ibo were Type I with complete vertical groove and Type III with intersect of groove for male and Type III for female. Type I’ with partial length groove was the predominant pattern for both male and female Hausa. The lip width and height of female Ibo were longer than that of the Hausa counterpart (P < 0.05), but none of the anthropometric variables could predict the lip print pattern. Conclusion The lip size and print could aid forensic investigation, though genetic diversity and heterogeneity of ethnic groups in Nigeria, especially that of Ibo, could setback use of lip print pattern to identify the ethnicity of an unknown individual in Nigeria to help determine the terrorist group to which they may belong.

“…In our study, combination of Type II+III (12.2 % and 16.2%) among males of both ethnic groups, for females Type III (11.4%) pattern among Bengalee Hindu group and Type II (25%) among Oraon community were the most common patterns. An earlier investigation had reported that the least common lip print type for both males (1.5%) and females (2%) was Type V (Rao and Kiran 2016). We found that a combination of Type I'+II (0.1%) in males and Type I'+IV (0.1%) in Bengalee females and a combination of Type I+II (0.6%) in males and Type III+IV (0.4%) among Oraon females were least common.…”

“…Interestingly, fourth quadrant demonstrated highest frequency of Type II and Type Findings of present study were compared with other recent studies from different parts of India and presented in Table 4. It was observed that the most common lip patterns among males were Type IV (36%) (Rao and Kiran 2016) and Type III (34.92%) (Sharma et al 2017) and among females is Type I (39.4%) (Rao and Kiran 2016) and IV (34%) (Kumar et al 2016). In our study, combination of Type II+III (12.2 % and 16.2%) among males of both ethnic groups, for females Type III (11.4%) pattern among Bengalee Hindu group and Type II (25%) among Oraon community were the most common patterns.…”

Lip print pattern (LPP) is unique to each individual. For decades, forensic experts have used LPP for personal identification to solve criminal cases. However, studies investigating ethnic variation in LPP are scanty. Our study wanted to investigate variation in LPP between two ethnic groups, Oraon tribals and Bengalee Hindus, residing in West Bengal, India. A total of 280 participants included 112 Oraons and168 Bengalee Hindus of both. Prints were taken using dark shaded lipstick and transparent cellophane tape and recorded into white A4 sheet. Prints were divided into four quadrants and examined by magnifying glass. For analysis of results, classification of Suzuki and Tsuchihashi was followed. A p value of 0.05 was considered to be statistically significant. It was observed that Type II pattern was dominant in first and second quadrants in both ethnic groups, irrespective of sex. Combination of Type II+III was found to be the most common pattern in males among both Oraons (16.2%) and Bengalee Hindus (12.2%) whereas in females Type II pattern (25.0%) among Oraons and Type III pattern among Bengalee Hindus (11.4%) was the most common. Chi square test showed statistically significant difference among females (p<0.05) and in third and fourth quadrants among males (p<0.01) of both ethnic groups. Our investigation clearly demonstrated sex and ethnic variations in LPP. Further studies are required to investigate ethnic variation in LPP among the various populations groups, both tribal as well as non-tribal, from different regions of India.
