Aim: The aim of this study is to evaluate the efficacy of cheiloscopy (the study of lip prints) and dermatoglyphics (the study of fingerprints) in screening diabetic patients., Materials and Methods: The study sample comprised 100 individuals in the age group of 17-60 years, of which fifty were diabetics and fifty controls who reported to the Department of Oral Medicine, Thai Moogambigai Dental College and Hospital. Lip prints were collected and categorized based on the Suzuki and Tsuchihashi system. Fingerprint patterns were obtained and classified according to the Henry's system of classification., Results: Type II and IV lip print patterns were predominant in diabetic patients and Type I lip print patterns in controls. The difference was statistically significant. There was no significant difference in fingerprint patterns between the study groups. Gender-wise analysis for lip print and fingerprint patterns did not yield significant results., Conclusion: Cheiloscopy is a potential screening tool for type 2 diabetes mellitus. Dermatoglyphics cannot be used as a screening tool in type 2 diabetes mellitus., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Journal of Forensic Dental Sciences.)

Context: "Identity" is a set of physical characteristics, functional or psychic, normal or pathological, that defines an individual. Identification of an individual is a crucial and an exigent task in forensic investigation., Aims: The aim of the present pilot study was to investigate the accuracy of various methods employed in gender determination such as lip prints, mandibular canine index (MCI), fingerprints, and correlation between them., Subjects and Methods: The pilot study group consisted of 300 samples aged between 18 and 25 years. Lip prints, fingerprints, and impressions of lower mandibular arches were collected., Statistical Analysis Used: The results were analyzed using Chi-square test for lip prints and fingerprints with an independent sample t -test for the MCI. Intergroup comparison between the parameters was analyzed by ANNOVA test., Results: Type II lip print pattern and loop pattern of fingerprints were the predominant patterns in both males and females, and mesiodistal width of right MCI has greater sexual dimorphism than left MCI., Conclusions: Although lip prints, fingerprints, and MCI had their own specifications, correlation of the three parameters did not show any significance., Competing Interests: There are no conflicts of interest.

Objective: The aim of this study was to evaluate the correlation between different cheiloscopic patterns with the canine relationship in deciduous dentition., Materials and Methods: Three-hundred children who were 3-6 years old with complete primary dentition were recruited and the relationships between maxillary and mandibular canines were recorded in the pro forma. Lip prints of the patients were recorded with the lipstick-cellophane method, and middle 10 mm of the lower lip was analyzed for the lip print pattern. The patterns were classified based on the Tsuchihashi and Suzuki classification., Results: Type II (branched) pattern was the most predominant cheiloscopic pattern. The predominant patterns which related to the terminal planes were Type IV (reticular) pattern for Class I, Type IV (reticular) and I (complete vertical) patterns for Class II, and the presence of Type V (irregular) pattern for Class III. Presence of Type I (complete vertical) and II (branched) patterns in males and Type II (branched) pattern alone in females can suggest for a Class II canine relationship., Conclusion: Lip prints can provide an alternative to dermatoglyphics to predict the canine relationship in primary dentition. Further studies with larger sample size are required to provide an insight into its significant correlations., Competing Interests: There are no conflicts of interest.

Forensic odontology is the application of dental principles to legal issues. It is an investigative aspect of dentistry that analyzes dental evidence for human identification. Sex determination is a subdivision of forensic odontology, and it is important especially when information relating to the deceased is unavailable. Sex determination becomes the first priority in the process of identification of a person by a forensic investigator in the case of mishaps, chemical and nuclear bomb explosions, natural disasters, crime investigations, and ethnic studies. Determination of sex/gender using skeletal remains presents a great problem to forensic experts, especially when only fragments of body are recovered. Forensic odontologist can assist other experts to determine the sex of the remains using teeth and skull traits. Various features of teeth such as morphology, crown size, and root length are characteristics for male and female sexes. There are also differences in the skull pattern and skull traits of two sexes. These will help forensic odontologists to identify the sex of the remains. The library dissertation contents and several articles and books were electronically searched in Google using the keywords "sex determination," "forensic dentistry," "sex determination in forensic dentistry." The contents were screened between 1950 and 2015 by going through the title and abstracts and full-text reading. The purpose of this article is to familiarize the different methods of sex determination., Competing Interests: There are no conflicts of interest.

Context: With the ever-changing field of criminal justice, the constant revision of criteria for acceptable evidence by the judiciary poses new challenges in forensic investigation. The applicability of cheiloscopy in individual identification is an area of extensive research in recent years., Objectives: The aim of the present study was to determine the distribution of different lip print patterns in North Kerala population, to assess any sexual dimorphism in lip patterns, and to correlate lip print patterns with ABO and Rh blood groups., Materials and Methods: A total of 858 students, 471 males and 387 females, from different colleges in the district of Kozhikode in North Kerala were included in the study. Lip prints were obtained using lipstick and cello tape and transferred onto white papers. Blood group of the participants was noted., Results: The most predominant pattern observed was Type I (48.3%), followed by Type II, Type III, Type IV, Type I', and Type V. We also observed that the lower lip exhibited an overwhelming predominance of Type I pattern in the North Kerala population while the upper lip showed a more even distribution. Gender-wise difference was observed with Type II being the most common in males and Type IV being the predominant pattern in females. No correlation was obtained between the blood groups and lip patterns., Conclusion: The potential usefulness of cheiloscopy in forensic medicine still remains largely untapped and under-recognized. Similar studies in different populations with large sample sizes will allow a more definite picture of lip print patterns to emerge., Competing Interests: Nil.

Forensic odontology is the branch of dentistry which deals with the proper handling, examination, evaluation and presentation of dental findings in the interest of justice. After major disasters and perimortem assaults such as earthquakes, fires, severe head and neck trauma or gross decomposition, accurate and early identification of dead and injured becomes important. In the absence of other records in such cases, identification is based on restorations, missing teeth and prosthetic devices such as partial and complete removable/fixed prosthesis or implant retained devices. This brings out the major role of prosthodontics to investigate the identity of suspects in the criminal cases as well as the deceased human beings in traumatic injuries or in disasters. Denture identification systems are being used as means of postmortem identification of edentulous persons which has evolved from the inclusion of some form of printed label in a denture to more high-tech methods. The provision of implant retained complete lower denture, antemortem, and postmortem radiographs of edentulous persons and correlation of bite marks using special impression techniques provide another potential source of evidence for human identification. Hence, this literature review throws some light on the role played by prosthodontist in forensic odontology., Competing Interests: There are no conflicts of interest.

Context: Forensic science is a branch of science that deals with the application of science and technology in solving a crime and this requires a multidisciplinary team effort. The word "Forensic" is derived from the Latin word, "Forensis" which means the study of public. Dental professionals should develop interests in contributing to legal issues., Aims: To study the lip prints among people of different races., Settings and Design: Descriptive study., Subjects and Methods: The present study comprised of ninety subjects of which Group A comprised of Africans, Group B comprised of Dravidian, and Group C of Mongoloid race. Each group was then further divided into 15 males and 15 females for whom the lip prints were recorded and evaluated., Statistical Analysis Used: ANOVA test., Results: ANOVA statistical analysis was used to compare three races of African, Dravidian, and Mongoloid races. The observed data among male and female were found to be significant with a P = 0.000492., Conclusion: The present study showed a significant difference in lip pattern among the three races. Perhaps future studies with a larger sample size and comparison between many other races may be done for better personal identification., Competing Interests: There are no conflicts of interest.

Background: Lip prints and fingerprints are considered to be unique to each individual. The study of fingerprints and lip prints is very popular in personal identification of the deceased and in criminal investigations., Aims: This study was done to find the predominant lip and fingerprint patterns in males and females in the North Indian population and also to find any correlation between lip print and fingerprint patterns within a gender., Materials and Methods: Two hundred students (100 males, 100 females) were included in the study. Lip prints were recorded for each individual using a dark-colored lipstick and the right thumb impression was recorded using an ink pad. The lip prints and fingerprints were analyzed using a magnifying glass. The Chi-square test was used for statistical analysis., Results: The branched pattern in males and the vertical pattern in females were the predominant lip print patterns. The predominant fingerprint pattern in both males and females was found to be the loop pattern, followed by the whorl pattern and then the arch pattern. No statistically significant correlation was found between lip prints and fingeprints. However, the arch type of fingerprint was found to be associated with different lip print patterns in males and females., Conclusion: Lip prints and fingerprints can be used for personal identification in a forensic scenario. Further correlative studies between lip prints and fingerprints could be useful in forensic science for gender identification., Competing Interests: There are no conflicts of interest.

Introduction: Personal identification is becoming increasingly important not only in legal medicine but also in crime/criminal investigation and identification. Sometimes establishing a person's identity can be a very difficult process. Dental, fingerprint, and DNA comparisons are probably the most common technique used. However, there are many well-known implanted methods of human identification, one of the most interesting emerging methods of human identification which originates from the criminal and forensic practice, is human lips recognition. Cheiloscopy is a forensic investigation technique that deals with the identification based on lip traces. The lip outline of every person is unique and can be used to fix the personal identity., Aim: The aim of this study was to assess the distribution of lip outline patterns among males and females, and to evaluate the uniqueness of lip outline pattern., Materials and Methods: The study group comprised of 200 individuals from Kamineni Institute of Dental Sciences. Lip outline patterns were obtained and were transferred to the proforma sheet for analysis., Results: The results of the study revealed that the lip outline patterns for each individual were unique., Conclusion: This study showed that lip outline patterns are unique to each individual and can be used for personal identification., Competing Interests: There are no conflicts of interest.

Introduction: The present study was undertaken with the objective of ascertaining whether latent lip prints generated by persistent lipsticks and developed using lysochrome dyes have the potential of use in sex determination and personal identification., Materials and Methods: This study included a total of 100 subjects (50 males and 50 females) whose latent lip prints were obtained by applying the persistent lipstick Revlon ColorStay Overtime(®) manufactured by Revlon(®) consumer products corporation, NewYork, USA, and lifting the prints with cellophane sheets. The prints were then developed using lysochrome dyes, and all the samples were blinded and then graded based on defined patterns from the Suzuki and Tsuchihashi classification., Results: No two lip prints were found to be alike. Type I was found to be the most prevalent type. In the female population, Type I (61%) was most prevalent, followed by Type I' (28%), Type II (9%), Type III (2%), Type IV (1%), and Type V (1%); in the male population, Type I (33%) was most prevalent, followed by Type II (23%), Type III (18%), Type IV (14%), Type I' (10%), and Type V (3%). Two examiners were able to determine the correct sexes from the given sample sizes. Their interobserver agreement was assessed using the kappa coefficient for males (κ =0.870) and females (κ = 0.870). Their accuracy was assessed with a confidence interval (CI) of 91.48-99.38., Conclusion: Lysochrome dyes are very efficacious in developing latent lip prints. This preliminary study has conclusively proved that latent lip prints developed with lysochrome dyes hold the potential for use in sex determination and can be maintained in a digital database.

Context: Cheiloscopy and dactyloscopy, both are well-established forensic tools used in individual identification in any scenario be it a crime scene or civil cause. Like finger prints, lip prints are unique and distinguishable for every individual. But their relationship to personality types has not been established excepting the hypothesis stating that finger prints could explain these personality patterns., Aims: The study was aimed to record and correlate the lip and finger prints with that of character/personality of a person., Settings and Design: The lip and finger prints and character of a person were recorded and the data obtained was subjected for statistical analysis, especially for Pearson's Chi-square test and correlation/association between the groups was also studied., Materials and Methods: The study sample comprised of 200 subjects, 100 males and 100 females, aged between 18 and 30 years. For recording lip prints, brown/pink-colored lipstick was applied on the lips and the subjects were asked to spread uniformly over the lips. Lip prints were traced in the normal rest position on a plain white bond paper. For recording the finger prints, imprints of the fingers were taken on a plain white bond paper using ink pad. The collected prints were visualized using magnifying lens. To record the character of person, a pro forma manual for multivariable personality inventory by Dr. BC Muthayya was used., Statistical Analysis Used: Data obtained was subjected for statistical analysis, especially for Pearson's Chi-square test and correlation/association between the groups was also studied., Results: In males, predominant lip pattern recorded was Type I with whorls-type finger pattern and the character being ego ideal, pessimism, introvert, and dogmatic; whereas in females, predominant lip pattern recorded was Type II with loops-type finger pattern and the character being neurotic, need achievers, and dominant., Conclusion: Many studies on lip pattern, finger pattern, palatal rugae, etc., for individual identification and gender determination exist, but correlative studies are scanty. This is the first study done on correlating patterns, that is, lip and finger pattern with the character of a person. With this study we conclude that this correlation can be used as an adjunct in the investigatory process in forensic sciences.

Background: Cheiloscopy or the study of lip prints is an important tool in forensic dentistry which is gaining popularity in current times. Not only has it proven effective in identification of individuals, but its role in sex determination has also been investigated. There are six different types of cheiloscopic/lip print patterns according to Tsuchihashi., Aims: The present study was conducted to find the prevalence of cheiloscopic/lip print pattern in 755 individuals and also to assess their efficacy in sex determination., Materials and Methods: According to classification by Tsuchihashi, the lip prints were analysed. Sex determination using lip print was done by method given by Vahanwala et al., Results: It was found that Type I was the most prevalent cheiloscopic pattern. Based on the method of sex determination using lip prints by Vahanwala et al., the percentage of individuals correctly identified was less., Conclusion: Although cheiloscopy holds promise as a supplementary tool along with other modes to recognize the sex of an individual, there is need for further studies using standardized methods to evaluate the same in larger population sizes.

Introduction: Lip print patterns are individualistic and unique and can be used for identification of individuals., Objectives: The objective of this study was to find out the different types of lip patterns, know the most common one and to know whether it has any gender predilection among adults of Sebha city., Materials and Methods: A total of 104 adults aged 18-35 years participated in this study. Lip prints were recorded and analyzed for lip print patterns. Statistical analysis was carried out using the computer software Statistical Program for Social Sciences (SPSS) 17.0 (Chicago, Illinos, USA)., Results: Type I lip print pattern was seen in 53.37% and 60.07% of lip quadrants in males and females, respectively. 27 (25.96%) subjects had same lip print pattern in all the four quadrants., Conclusion: Suzuki and Tsuchihashi's Type I lip print pattern was most common type of lip print pattern in the studied population, whereas Type I' was found to be the least common.

Context: Identification of an individual is a pre-requisite for certification of death and for personal, social, and legal reasons. The study of lip prints (cheiloscopy) was thought as a method for identification of a person. It is safe to assume that cheiloscopy, in its present stage of development, has become a means of criminalistic identification dealing with lip prints., Aim: The first aim of the study was to evaluate the visible lip patterns in Rajasthan population in relation to the gender and to ascertain the existence of hereditary pattern followed among parents and offsprings. The second aim was to compare visible and latent lip print patterns on non-biological materials like tracing paper, microscopic glass slides and stainless steel tumblers., Materials and Methods: The lip prints of 300 subjects including 25 families were obtained using lipstick. Out of these 300 individuals, 60 were selected for latent lip prints. In order to prevent any intra- and inter-observer variability single observer carried out all the observations. The lip prints were analyzed using magnifying lens and were classified using the criteria given by Suzuki and Tsuchihashi. The determination of the pattern in each segment of the lip was based on the numerical superiority of properties of the lines on the fragment., Statistical Analysis Used: After recording all the values for various parameters, data obtained were statistically analyzed with the help of the Statistical Package for Social Sciences software version-13 using independent t-test. For all the tests, a P value of 0.05 or less was considered., Results: In the present study, most predominant pattern in the entire study population among upper and lower lips considering both males and females was type III lip pattern. Hereditary resemblance was observed between parents and offsprings in 37.66%. The latent lip prints were better visualized on microscopic glass slide when compared to stainless steel tumblers., Conclusion: Lip prints have a good potential for use in criminal investigations. They have been used only occasionally despite their frequent occurrence at crime scenes. A place for cheiloscopy is recommended within the scope of forensic odontology, along with other means of forensic identification.

Background: The interaction between the offender and the victim produces visible or latent prints on objects and utensils. The study of lip prints has reportedly stayed away from the basic cinematic concept of the lip-to-surface relationship., Materials and Methods: Three regular powders were used to reveal the latent lip prints on a typical metallic straw called bombilla, and the revealed prints were photographed, preserved, and analyzed., Results: Better definition was observed in the lower lip print, and nine anatomical patterns were identified, but a higher definition of wrinkles was observed with indestructible white powder., Conclusion: Knowledge of labial dynamics, the real value of the processed surfaces, and the need for testing in field conditions are discussed.

Aim: To evaluate the uniqueness and to define a standard method for the analysis of lip prints., Materials and Methods: Lip prints of 100 students were taken using Scotch tape without any distortion. These prints were then scanned for the digital analysis. Using Adobe Photoshop 7 software an attempt was made to trace each and every line using Suzuki and Tsuchihashi's classification. Weighted value scoring system was used to check for the uniqueness of the lip prints., Results: No two lip prints had exactly matching scores in all four Quadrants. No statistically significant difference was found in the change of pattern in lip print images collected after 12 months from the same individual. With digital analysis, up to 15 lines were traceable in 66%, 71%, 52% and 51% of Quadrant I, II, III and IV respectively., Conclusion: Lip prints are unique to an individual. The digital method of analyzing lip print images serves better visualization, ease in identification and recording of the lip print pattern. Weighted Value Scoring system can be considered as a standard method for determining the uniqueness of the lip prints.

Aims and Objective: The study aims to develop latent lip prints on glass surface using fingerprint black powder and its comparison with standard lipstick prints and also determines the effectiveness of the technique., Materials and Methods: This study included a total of 100 subjects, comprising of 50 males and 50 females with age ranging from 17 to 38 years. Latent lipprint was developed by pressing the lips against a glass slab with lips together and the print formed was developed by sprinkling the black finger print powder and transferred to a bond sheet. Subsequently, standard lipstick print was developed from the same subject. All the samples were coded and graded according to the patterns suggested in the literature., Results: Out of 100 latent prints only 29 prints showed lip patterns in all four quadrants. The percentage matching with self lipstick print of good latent prints ranged from 25% to 100% and those of random prints ranged from 8% to 92%. Quadrant wise matching ranged from 52.67% to 57.67%. Statistically significant difference was observed between males and females., Conclusion: The study demonstrates the usefulness of latent lip print in personal identification.

Background: Identification is of paramount importance in any forensic investigation. Positive identification of living or deceased using distinctive traits is a cornerstone of forensic science. The uniqueness of these patterns and subtle distinction between traits has offered worthy supplemental tools in establishing the true nature of facts., Aim: The first aim of our study was to determine the most common pattern of lip prints, palatal rugae, and finger prints in the study subjects. Secondly, to determine if any specific pattern of lip print, palatal rugae, or the finger print concurs in individuals, and thereby establish a database of these prototypes for human identification from a defined cohort., Materials and Methods: The sample size comprised 100 female students of a dental college staying together in the hostel. Lip prints were recorded on a white bond sheet using lipstick, palatal rugae on dental casts, and finger prints using printer's blue ink., Results: Our observation suggested that the reticular pattern of lip print, the wavy pattern of palatal rugae, and the loop pattern of finger prints were the predominant patterns. Correlation of the three parameters did not reveal significant differences., Conclusions: This approach of human identification utilizing conventional techniques and relevant parameters is pertinent in defined groups. However, larger representative sample with robust analytical tools may provide a necessary blueprint of human identification.

Background: Cheiloscopy is a forensic investigation that deals with the examination of the system of furrows on the red part of human lips. Like fingerprint, lip print is also unique for every individual. But most of the crime-detecting agencies are unaware of the importance of lip print and it is not commonly attempted in identification of the suspects., Aim: The aim of the present study is to determine the predominant lip print pattern among Pondicherry population, India, and also to determine its uniqueness., Materials and Methods: The study comprised of 60 students (30 males and 30 females), aged from 17 to 25 years, from Pondicherry population, India. A dark-colored lipstick was applied with a single stroke and the students were asked to rub both the lips to spread the applied lipstick, after which a lip print was made on butter paper. The lip print was visualized with magnifying lens., Statistical Analysis: Percentage calculation method was used to identify the predominant lip pattern. One-sample T test was done to identify the statistical significance within the different types of lip pattern with P value <0.05., Results and Conclusion: The present study concludes that every individual has unique lip print and Type III appears to be the most predominant pattern in males, followed by the Type II, Type IV, Type I and Type V patterns. In females, Type II appears to be the most predominant pattern followed by the Type IV, Type I, Type III and Type V patterns.

Introduction: Establishment of a person's individuality is important for legal as well as humanitarian purpose and gender determination is an essential step in identifying an individual. In forensic odontology the sum total of all the characteristics of teeth and their associated structures provide a unique totality and forms the basis for personal identification., Aims and Objectives: To investigate the accuracy of various methods employed in sex determination such as cheiloscopy and mandibular canine index (MCI)., Materials and Methods: The study group comprises adults between 20 and 25 years of age, who were assessed for gender identification using lip prints and MCI. The results were subjected to statistical analysis., Results: MCI and lip prints were found to be accurate and specific for sex determination., Conclusion: There is scope for use of these methods in criminal investigations, personal identification, and genetic studies. Thus, dental tissues make good witnesses although they speak softly, they never lie and they never forget.

Context: It has been proved that lip prints are analogous to thumb prints. A correlation between thumb prints and sagittal dental malocclusion has already been established. Soft tissue is gaining more importance in judgement of deformity or identity of a patient., Aim: To find a correlation between sagittal skeletal jaw relation and lip prints., Settings and Design: Descriptive, cross-sectional, comparative, single-blind, hospital-based study., Materials and Methods: A total of 90 patients were categorized into skeletal class I, class II, and class III, comprising 30 patients in each group with equal gender distribution. Dolphin imaging (10.5) software was used for analyzing sagittal jaw relation. Lip prints obtained from these 90 patients were analyzed. STATISTICAL ANALYSES USED: Karl Pearson's correlation coefficient, Chi-square test, t-test, Spearman's co-efficient, analysis of variance (ANOVA)., Results: It was observed that angle ANB (Angle formed between points nasion[N] to Subnasal[A] and nasion[N] to supramental [B]) and beta angle were statistically significant, revealing a strong negative correlation (-0.9060) with different classes of jaw relation. Significant difference was observed between genders in all the three classes. Significant difference was observed in relation to lip print and the quadrants of upper and lower lips. A statistical significance was noted on the right side of both upper and lower arches., Conclusion: This study shows that lip prints can be employed for sagittal jaw relation recognition. A further study on various ethnic backgrounds with a larger sample size in individual group is necessary for comparing lip prints and malocclusion.

Background: Lip prints are unique to each individual and can be used for personal identification. The lip prints show differences according to the race and the ethnic origins of a person., Aim: The objective of the study was to determine the predominant lip print type in a Punjabi population., Materials and Methods: The study was conducted on 106 students of our institution and comprised 56 males and 50 females in the age group of 18-25 years. The middle part of the lower lip was taken as study area. Analysis of lip print pattern was done according to Tsuchihashi Classification., Results: No two lip prints matched with each other. Type 1 pattern (vertical grooves that run across the entire lip) was found to be predominant in both males (51.02%) and females (43.47%) and there was no statistically observed difference between males and females in individual lip print types., Conclusion: In our study, lip prints did not match with each other, hence lip prints are unique and further studies with larger samples are required to obtain statistical significance.

Background: Personal identification is an integral part of forensic investigations. For the same, DNA profiling and fingerprints are the most commonly used tools. But these evidences are not ubiquitous and may not necessarily be obtained from the crime scene. In such a scenario, other physical and trace evidences play a pivotal role and subsequently the branches employed are forensic osteology, odontology, biometrics, etc. A relatively recent field in the branch of forensic odontology is cheiloscopy or the study of lip prints. A comparison of lip prints from the crime scene and those obtained from the suspects may be useful in the identification or narrowing down the investigation., Aim: The purpose of the present study is to determine the gender and population variability in the morphological patterns of lip prints among brahmins, Jats, and scheduled castes of Delhi and Haryana, India., Settings and Design: Samples were collected from Jats, brahmins, and scheduled castes of Delhi and Haryana. The total sample size consisted of 1399 individuals including 781 males and 618 females in the age group of 8-60 years. Care was taken not to collect samples from genetically related individuals. The technique was standardized by recording lip prints of 20 persons and analyzing them., Materials and Methods: Lip prints were collected by using a corporate's invisible tape and analyzed using a hand lens. The patterns were studied along the entire length and breadth of both the upper and the lower lip. The data were analyzed by SPSS statistical package version 17 to determine the frequencies and percentages of occurrence of the pattern types in each population group and a comparison between males and females among the groups was carried out by using the z test., Results and Conclusions: The z-test comparison between patterns of males and females shows significant differences with respect to pattern types I', II, III, and IV among brahmins; I', II, III, IV, and Y among Jats; and I, I', II, III, and V among scheduled castes. Thus, it can be concluded that the variability of the lip print pattern can help sex differentiation among groups and that more studies on the lip print pattern should be carried out to bring new dimensions to forensic anthropology and to aid the law enforcement agencies.

Identification plays a very important role in any crime investigation. Cheiloscopy helps in identifying the humans based on the lips' traces. The pattern of wrinkles on the lips has individual characteristics like fingerprints. A review of the literature reveals very little research done on lip prints so far. The present article reviews in detail the history, scope of cheiloscopy, and the use of lip prints in crime detection. It also highlights the current research carried out in the field of cheiloscopy. An effort has been made to help the researchers by reviewing in detail the various methods of classifying and analyzing the lip prints. It concludes by enlightening the readers with the fact that the possibilities to use the red part of lips to identify a human being are wider than it is commonly thought.

Objective: The aim of this study is to determine the distribution of different lip print patterns among subjects having different ABO and Rh blood groups and to determine the correlation between their characters and blood groups., Materials and Methods: The present study was done on 150 individuals who were randomly selected and blood groups of these subjects were analyzed., Results: The results revealed no association between distribution of lip print (cheiloscopy) pattern and blood groups., Conclusion: Lip print pattern does not show any correlation between blood groups.

Aim: Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. The aim of this study is to establish the uniqueness of lip prints which aids in personal identification., Materials and Methods: The study group comprised of 200 subjects. The materials used were dark-colored lipstick, paper, cellophane tape, a brush, and a magnifying lens., Results: This study shows that lip prints are unique and permanent for each individual, and the lip prints among family members and between twins revealed different patterns on the whole with few similar grooves suggesting the existence of heredity in the lip prints., Conclusion: Our study showed that lip prints are unique to each individual and can be used for personal identification.
