Background: The prevalence of obesity has been steadily increasing worldwide. Reliable and noninvasive tools that can be used to diagnose such conditions may help us in mass screening and prevention. Finger prints and lip prints have been used as the genetic markers in some diseases such as diabetes mellitus. Studies to correlate a possible association of such markers among obese individuals have not been reported in India to date. The present study was conducted to determine and compare the lip print and finger print patterns in normal and obese individuals and also to evaluate any possible correlation between the lip prints and finger prints in both the study groups. Methodology: Lip and finger print patterns of 100 obese and equal number of age- and sex-matched healthy individuals were analyzed. Right thumb, right index, left thumb and left index finger prints were evaluated. Gender-wise comparison was also made. Results: Lip prints revealed no significant difference between obese and nonobese individuals. Predominant Type I lip print was observed in both the study groups. Comparison of finger prints between obese and nonobese individuals revealed a highly significant results for all the fingers. Predominant finger print patterns in the right thumb, right index, left thumb and left index among obese individuals were whorl (51%), loop (83%), whorl (79%) and arch (74%), respectively. No correlation between the lip prints and finger prints was noted. Conclusion: Finger prints in the obese individuals showed significant differences when compared to the normal controls while lip prints failed to reveal any significant difference. Lip prints did not correlate with the finger prints. Right thumb revealed a significant gender difference among obese individuals. [ABSTRACT FROM AUTHOR]

Introduction: Personal identification is becoming increasingly important not only in legal medicine but also in criminal investigation, identification and in Genetic Research. The grooves present on the lips are unique for every person. Cheiloscopy is a forensic investigation technique that deals with the identification based on lip traces. The aim of this study was to assess the specific lip print pattern for personal identification, its uniqueness among males and females and the reliability of the technique in suspect identification at the crime site. Materials and Methods: The study sample comprised 200 individuals (100 males and 100 females) aged between 10 and 50 years; dark-colored lipstick was applied uniformly on the lips and clear impressions of the lips were taken on the bond paper. The scanned lip-print image studied using Microsoft office picture manager. Fingerprints were analyzed by following the classification given by Suzuki and Tsuchihashi. Chi-square test and p-value of the samples were calculated. Results: The study revealed that the lip print patterns for each individual were unique and there was no peculiar pattern distribution among male and female subjects. Conclusion: Cheiloscopy is analogous to fingerprint analysis and can be used as a tool for individual identification along with dermatoglyphics. It can also be used as an aid in forensic sex determination. [ABSTRACT FROM AUTHOR]

Background: The most crucial evidence that is left behind at the crime scenarios that might narrow down the suspect pool are lip prints and fingerprints. These are undoubtedly the most reliable and valuable evidence till date in the court of law. One more biological record that remains unchanged throughout the lifespan of a person is the blood group.Aim and Objectives: To study, correlate and compare cheiloscopy and dactyloscopy with blood group among dental students in the Western Maharashtra population.Materials and Methods: A total of 200 dental students with age groups ranging between 18-25 years were included in the study. Lip print pattern, fingerprint pattern and ABO blood groups were collected and compared. SPSS version 20.0 was used to analyse the data.Results: There was a statistically significant correlation between lip prints and ABO - Rh (χ2 37.56, P < 0.05) as well as between fingerprints and ABO-Rh blood groups (χ2 30.6, P < 0.05).Conclusion: Hence, this study concluded that fingerprints-ABO blood group and lip prints-ABO blood groups are valuable evidence that can be relied upon in forensic investigations for the identification of the suspect in crime.

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. [ABSTRACT FROM AUTHOR]

Most transgenders in India reside in secluded or in outskirts of society with very low status; they are often addressed in a very derogatory manner by the society. The Indian sub-continent displays a variety of studies undertaken by the cheiloscopic experts and most researchers could differentiate the two genders due to their characteristic lip pattern. Many of them carried out double blind study inorder to identify the gender on the basis of lip-patterns identified by them. But the "third gender" was left out and never taken into consideration. Present cheiloscopic study throws light on various lip-patterns present in them and whether they have characteristic patterns. The paper also reviews the relevance of various studies undertaken in Indian Subcontinent, social problems existing in transgenders and further explains cheiloscopic relevance in forensics [ABSTRACT FROM AUTHOR]

Context (Background): Lips prints are unique and are a tool for personal identification.Aims: Indian population can be divided into different ethno-racial groups. In this study, we aimed at finding the most and the least prevalent lip print patterns in these groups and also to observe any similarities or differences that may exist in these groups in terms of lip print patterns.Settings and Design: Lip prints in 755 individuals categorized into different ethno-racial groups were studied.Materials and Methods: Brown- and pink-colored lipsticks, cellophane tape, and magnifying lens were used to record and study the lip prints.Results: Among all the three ethno-racial groups, Type I was the most prevalent lip print pattern observed. The least prevalent lip print pattern in all the three groups was Type IV. Inference/Conclusion: Lip prints hold potential as supplementary tools for identification where they can be recorded with ease. The observation and classification of lip print patterns in different ethno-racial groups not only provide some useful data but also open a new window to a field that can contribute extensively to criminal investigation and identification.

Background: Identification of an individual plays an important role in both civil and criminal investigations. Fingerprinting is widely accepted and practiced method of identification throughout the world because of its uniqueness. Similarly researches done previous shows that lip print pattern is also unique and is helpful in identification. Objective: To correlate fingerprint with lip print pattern and also to determine the predominant fingerprint and lip print pattern in males and females, in Gujarati population. Materials and Method: Cross-sectional survey was conducted in a teaching hospital Vadodara, Gujarat, India. A total of 200 subjects (100 males and 100 females), between 18 - 24 years of age, were the study subjects. Fingerprint and lip impressions of all the subjects were recorded, and the results were analyzed based on Henry system for fingerprints and Suzuki & Tsuchihashi classification for lip prints. Results: There exists a correlation between the fingerprint and the lip print pattern in both males and females (p <0.001), which was highly significant sex-wise. In the male (63.9%) and female (66.6%) loop fingerprint pattern was the predominant type. In the case of lip print pattern in male Type III (42%) and female Type I (37%) was the most predominant type. Conclusion: There is a correlation between fingerprint and lip print patterns in both males and females. The study also revealed that finger and lip prints are unique to each and can be used as an identification tool in civil and criminal investigation. [ABSTRACT FROM AUTHOR]

Background: The lip print pattern is a unique among individuals and thus helps in the identification during the forensic investigation. Lip print analysis in the forensic scene may help in the personal identification. Thus, correlating the lip print with the finger print and gender will create a new room in forensic dentistry investigation. Aim: This study aims to identify the lip and finger print pattern and to correlate lip and finger print pattern for gender identification. Materials and Methods: A total of 100 students from dental institution were included in this study. Of which, 50 were male and 50 were female.. Their aged range between 18 and 28 years with a mean age of 21.3 years. The physiological rest position of the lip print was recorded by the application of red or dark pink colored lipstick over the lips and the imprint was transferred over a white chart sheet through a transparent tape. The imprint of the finger was taken directly on a white chart sheet. The lip and finger print pattern was examined with magnifying lens. The results were analyzed using SPSS software 19.0 (Armonk, NY, USA) and presented as a descriptive statistics. A correlation of lip print with finger print and gender variation was analyzed by Pearson correlation test. Results: The study identified higher prevalence of Type II (34%) lip print pattern in the overall study population. In males, Type I lip print (42%) and plain loop finger print pattern (44%) was frequent in the study. In males, the correlation of lip and finger print patter showed weaker correlation and statistically insignificant (P = 0.436). In females, Type II lip print (34%) and plain loop finger print pattern (42%) was frequent in the study. In females, the correlation of the lip and finger print pattern showed weaker correlation with approachable statistical significance (P = 0.083). The correlation of lip and finger print with gender showed weaker correlation and approachable significance (P = 0.07). The association of lip and finger print in the study showed statistically insignificant. However, the association of Type III lip print pattern with loop finger print pattern showed statistical significant association (P = 0.05) by Chi-square analysis. Conclusion: Lip print analysis is a challenging area in the personal identification during forensic dentistry examination. The study revealed the weaker correlation and approachable significance of lip and finger print pattern in gender identification. Future studies should be encouraged in the direction of software based identification for lip and finger print analysis in gender identification. Such studies may benefit this study pattern in more accurate way. [ABSTRACT FROM AUTHOR]

Lip prints are unique to each individual. They remain the same throughout life and are uninfluenced by environmental changes, diseases and trauma. The present study was conducted at Kasturba Medical College, Mangalore, India among 200 randomly-selected medical students belonging to age group of 18–25 years. The sample consisted of 100 north Indians (50 males and 50 females) and 100 south Indians (50 males and 50 females). The lip prints were documented as per Suzuki's classification. Type II was the most commonly occurring lip print pattern and type V was the rarest. Type I and type I' patterns were more common in males and Type II, type III, type IV and type V patterns were more common in females. Type III and type IV patterns were predominant in north Indians while type II was predominant in south Indians. No significant relation exists between the lip prints and blood group pattern of an individual. Results of the study showed that lip prints are individualistic, and bears a relationship with sex and geographical distribution of the individual. Thus, lip prints can be useful as evidence in the court of law. [ABSTRACT FROM AUTHOR]

Introduction When fingerprint, DNA and post-mortem records are not available, lesser known techniques of palatoscopy and Cheiloscopy can throw light on individual identification. The present study was conducted to compare the Lip prints between the Tibetan population from Mundgod and the population of Belgaum and to find out the quadrant wise and gender-wise predilection of lip print patterns. Material and Methods Lip impressions were collected from 775 Tibetans from Mundgod and 764 subjects from the population of Belgaum city. A dark shaded lip stick was applied on the lips of the subjects and the impressions were taken on the sticking side of a cellophane tape and stuck on a white paper. The impressions were visualized using a magnifying lens and analyzed by Suzuki's classification. Findings The data was entered in Microsoft excel and analyzed using Chi square test. The Type I pattern was more common in males in the first and second quadrants. Type II pattern was more in the Tibetans than in the general population. Type III pattern was more common in males. It was seen more commonly in the Tibetans. Type IV pattern occurred more frequently in females in both the populations. The variability in occurrence of different types of lip prints in both the populations was statistically significant. Lip size of the Tibetans was larger than their counterparts from the general population. Conclusion Lip prints have a gender-wise as well as quadrant-wise predilection. The two races compared in this study were found to have differences in the distribution of lip prints. [ABSTRACT FROM AUTHOR]

Lip prints can provide vital information that may be useful for the purposes of forensic investigations. The current study was undertaken with the aims of determining the distribution and predominant lip-print patterns in a Central Indian (Marathi) population and evaluating whether any sex differences exist. The study subjects were 400 healthy consenting volunteers - 200 males and 200 females - aged 18-25 years, from the Marathi community. A simpler and more convenient method of data collection - digital photography - was used. The central (most motile) 1 cm(2) portion of both upper and lower lips was analysed digitally. As per Suzuki and Tsuchihashi's classification, overall, Type IV (27.5%) and Type III (6.25%) were found to be the most and least prevalent patterns, respectively. The Type II (32%) lip-print pattern was found to be most predominant in males, while Type IV (32.5%) was found to be most commonly occurring in females. Statistically significant differences (p < .01) were observed between lip-print pattern types in males and females., (© The Author(s) 2015.)

Lip prints are the normal lines and fissures in the form of wrinkles and grooves present in the zone of transition of human lip, between the inner labial mucosa and outer skin. Yasuo Tsuchihashi (1974) presented a standardized classification of his own, for different types of lip print. He has classified lip prints into five types, which forms the basis of categorizing lip prints. Keeping the above classification as a basis, the present study was conducted to identify whether there are any other types of lip prints apart from these five types or to identify any subtypes available within these five types. Among the outpatients and their accompanying persons who attended the Department of Oral Medicine and Radiology, Saveetha Dental College, Chennai, 750 (348 males and 402 females) individuals were selected for the present lip print analysis study. From the present study it can be concluded that there are no new types of lip prints be identified, but there are subtypes present in Type II and Type V lip prints which can serve as an important tool in forensic dentistry for personal identification and criminal investigation.
