Objectives: This study aimed to assess the lip prints of Indian twins and non‑twin siblings to evaluate the existence of heredity in the lip prints of these individuals. Materials and Methods: The study employed a blind, cross‑sectional, quantitative approach with an inductive method and extensive direct observation. The sample consisted of 30 twins and 30 non‑twin siblings, divided into three groups based on gender with 10 subjects in each subgroup. All participants were aged between 10 and 30 years and were instructed on the methods and techniques involved in the study. Results: The lip prints of participants were recorded using dark‑colored lipstick, bond paper, cellophane tape, and a brush, and were examined for lip thickness measurement (in mm), classification of lip commissures, and assessment of groove patterns. The findings were then analyzed to determine the pattern of lip prints among twins and non‑twin siblings. Conclusion: Cheiloscopy, the forensic investigation technique based on lip trace identification, could benefit from this study’s findings as it explores the existence of heredity in lip prints of Indian twins and non‑twin siblings.

This study aimed to conduct a systematic review to gather evidence to clarify if cheiloscopy can be used in sex estimation and identify the reasons behind the lack of consensus in the scientific community. The systematic review was performed following the PRISMA guidelines. A bibliographic survey was conducted in PubMed, Scopus, and Web of Science databases, restricted to articles published between 2010 and 2020. Studies were selected according to eligibility criteria, and then the study data were collected. The risk of bias in each study was assessed and applied as additional inclusion or exclusion criteria. The results of the articles eligible for analysis were synthesized using a descriptive approach. In the 41 included studies, several methodological flaws and variations between studies that contribute to the discrepancy in results were identified. The data gathered allowed us to conclude that there is no strong scientific evidence to support the use of cheiloscopy in sex estimation, as there is no specific pattern for each sex, which reduces the criminalistic interest of cheiloscopy in estimating this parameter.

Lip traces and teeth marks can play an important role in identifying people, as forensic sciences based on new technologies are constantly evolving. As for lips, the pattern of wrinkles on them has individual characteristics like fingerprints, so lip print studies have come to attract the attention of scientists as a new tool for human identification. Coming into contact with the body or clothing of other people, with smoking items and various kitchen utensils, the lips, through cosmetic deposits, saliva deposits and food, form traces that are suitable for use in criminal investigation activity. Scientific research undertaken by specialists in the field demonstrates that lip traces can reproduce characteristic elements of shape, size and relief (disposition of the papillae, the vertical groove of the upper lip, and the dimple of the lower lip) which, under certain conditions, can ensure the identification of the author. In their turn, teeth marks have an important value in identifying people, they can be found especially in the case of crimes of violence, rape, robbery (both on the body of the victim and the aggressor), but also in the case of other non-violent crimes, when such traces are left on the crime scene in various bitten food products (cheeses, fruits, such as apples, pears, etc.), capable of delicately preserving the details of the teeth pattern. In both cases, through this study we aimed to highlight the most important aspects related to the forensic research of lip traces and teeth marks, their expertise, as well as the limits and challenges related to the probative value of the expertise carried out in the case.

Background: The concept of lip prints is clear from previous literature review that this evidence can be used for forensic purpose. While accepting that a body of data existed regarding the individuality of lip pattern, there is no credible research on the stability of the lip detail over time. The timescale in question could be measured in weeks and months or years. The former would be used in police investigations and the latter can be used by geneticist. [ABSTRACT FROM AUTHOR]

Introduction: India is one of the largest countries which is inhabited by diverse populations of different tribes, castes, religious, and migrant groups. In forensic investigation, personal identification plays the greatest importance. Lip prints are considered as one such tool for personal identification. Study of lip prints is referred to as cheiloscopy and they are considered as unique in every individual just like fingerprints. Materials and Methods: Three hundred randomly selected specimens were taken in our study comprising of both the genders and of various regions from Odisha, West Bengal (WB) and Bihar was considered in the study. The age selected in our study ranged from 18 to 25 years comprising of 151 males and 149 females. Lip impression was made and viewed for different lip prints pattern under a magnifying glass of 10X. Results: There was a total of six lip print type identified in the present study. The type of lip print pattern found more in males was Type 2 and in females was Type 1. The type of lip print pattern found more in Bihar and WB was Type 2 and Odisha was Type 1. Conclusion: As the lip print is unique for every individual, Cheiloscopy is considered as a useful method of identification in forensic odontology. The study showed statistically significant difference in gender with a variation in geographical location. [ABSTRACT FROM AUTHOR]

Lip print (LP) evidence can be an essential tool for human forensics. LPs have conventionally been developed using substances such as lysochrome dyes, fluorescent dyes, indigo dye, aluminium powder, and silver metallic powder. However, techniques for LP enhancement from various substrates are currently inconsistent and lack standardisation in practice. This review summarises current knowledge on the physical and chemical techniques of LP enhancement, identifies limitations, and provides suggestions for future research on practical applications of cheiloscopy as a forensic tool in criminal justice. The grooves and wrinkles of the human lip establish unique patterns that persist throughout life. Cheiloscopic patterns exhibit discriminatory individual characteristics that may constitute circumstantial forensic evidence. Enhancement techniques for latent lip prints on porous and nonporous substrates can be classified as physical or chemical. Unlike fingerprint, there is a current lack of consistency and/or standardisation on latent lip print enhancement methods in frontline forensic practice. [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: Personal identification has an important role in forensic sciences. Lip print and thumb print can be used for personal identification since they are unique for individuals and do not change during the life of a person. Objective: To analyse predominant patterns of lip print in females and males, To analyse predominant patterns of finger print in females and males, To identify if there exists any correlation between lip prints and finger prints. Material and Method: A cross sectional study was conducted in Sathyabama Dental College among 500 individuals (250 females and 250 males) between age group of 18-40 years. Fingerprint and lip print of all the subjects were collected and compared, and the results were analyzed based on Micheal Kucken classification system for fingerprints and Suzuki and Tsuchihashi classification for lip prints. Descriptive and inferential statistics were carried out. Level of significance was set as 0.05. Result: Reticular lip print pattern was found in majority (36.4%) of the males, whereas vertical grooves (29.6%) and branched grooves (29.6%) are common in females. Finger prints showed that loop pattern is more common in both males and females. This study showed a significant correlation between lip prints and thumb pattern in males while females showed no significance. [ABSTRACT FROM AUTHOR]

Cheiloscopy is a forensic investigation technique that deals with the identification based on lip traces. Based upon the research, it was established that the arrangement of lines on the red part of human lips is unique for each human being. The present study is an attempt to determine the pattern of lip prints and evaluate its uniqueness in a sample of Naga population and also their association with print in the four quadrants of the lip. A total of 100 (15-40) years individuals were randomly selected. With the help of brush a layer of lipstick was applied on the lips of the subject. Following the basis of Tsuchihashi's classification the lip prints collected were studied. It was found that Type I' pattern was predominant among the studied subjects followed by Type I and Type III pattern while Type V pattern was the least frequent Lip pattern distribution in (all four quadrants) in both males and females of Nagas. It is found that no two or more persons had similar features of lip grooves. The frequency of repetition of the lip print pattern in successive quadrant is found to be high. Lip print pattern can be used as an additional tool for personal identification. [ABSTRACT FROM AUTHOR]

Introduction: Cheiloscopy and dactyloscopy have long been the most commonly used methods for forensic investigations. Orthodontists perform numerous diagnostic procedures, which include radiographs, photographs and impressions of the teeth and palate for the evaluation of malocclusion. The data recorded by them provide immense information about a patient. Fingerprints, lip prints and palatal rugae have been considered the most stable, reliable, imitable, convenient, cost-effective and time-friendly modes of investigating crime and other purposes. Aim: The main aim of this study is to correlate cheiloscopy, fingerprint pattern and palatoscopy to skeletal Class I sagittal jaw relationship and to include cheiloscopy, fingerprint pattern assessment and palatoscopy in routine orthodontic investigation procedures as an adjunct procedure in individual identification. Methods: Fingerprints, lip prints, palatal rugae pattern and lateral cephalograms of 37 skeletal Class I patients were obtained using standardized procedures. Results: In Class I skeletal malocclusion, the maximum number of patients exhibited ulnar loop dermal pattern, Type 1 and Type 2 lip patterns and a wavy rugae pattern (Kapali et al. primary classification). Conclusion: Orthodontists prepare various antemortem records for diagnostic purposes, i.e., photographs, the impression of the teeth and palate, lateral cephalograms, orthopantomograms and hand-wrist radiographs. If orthodontists recorded additional data of finger and lip prints, the archives of an orthodontist would be of tremendous profit to forensic sciences in individual identification.

Loop finger print patterns were found to be predominant among males.Whorl finger print patterns were found to be predominant among females. Positive correlation (+0.80) was found between loop finger print pattern and Type 1' lip print pattern in males which is statistically significant (p=0.003).Positive correlation (+0.75) was found between whorl finger print pattern and Type IV lip groove pattern in females which is statistically significant. (p=0.005) Conclusion: There was definite correlation of Cheiloscopy and Dermatoglyphics in gender determination. [ABSTRACT FROM AUTHOR]

Lip prints are defined as the grooves and wrinkled patterns present on the labial mucosa. They are admissible as evidence in the court of law as they are found to be unique and permanent which do not change during the life span of an individual. In this paper, a pilot study was done to ascertain the sex and race of an individual by studying their lip print patterns. The targeted experimented group included Indian(Caucasoid) and African(Negroid) students, both male and female studying at Gujarat Forensic Sciences University, Gujarat. The successful inter-comparison according to the race and sex of the exemplar was done giving a definite result that the cheiloscopy can aid in identification of an individual by establishing his or her race and gender.

Aims and Objectives: The aim of the study was to evaluate and compare lip prints and palatal rugae pattern in Kerala, Karnataka, and Manipuri population. Materials and Methods: The study involved 180 individuals (60 each from Karnataka, Kerala, and Manipuri population). Lipstick was used to record lip prints, which were visualized by magnifying lens. Palatal rugae were recorded on maxillary casts of all subjects and analyzed following Kapali S et al.' s classification. Statistical Package for the Social Sciences version 20 for Windows software was used for analysis. Results: Among the study population, most frequent lip print pattern was Type 3 and least was Type 1'. When patterns were compared between groups, Type 3 was the most common in Manipuri and Kerala and Type 3 in Karnataka groups. In the entire population, males showed Type 3 and females showed Type 1. On analysis of overall rugae wavy, forward and divergence patterns were predominant. On comparison of gender, males demonstrated greater number of wavy and perpendicular rugae, and females had curved, straight, forward, and backward. Conclusion: Both cheiloscopy and rugoscopy have the prospective to recognize an individual. Cheiloscopy is more reliable than rugoscopy in making out the group and gender of an individual.

Cheiloscopy, the study of lip prints, is a tool in forensic investigation technique that deals with identification of individuals based on lips patterns. The objective of this study is to determine predominant lip print pattern found among the Gujarati population, to evaluate whether any sex difference exists and to study the permanence of the pattern over 6 months duration. The study comprised of 100 healthy individuals (50 males and 50 females), in the age group of 18-25 years of Gujarati population of the Gandhinagar region of the Gujarat state, India. By using Suzuki and Tsuchihashi classification, Lip prints were then divided into four quadrants and also classified on the basis of peripheral shape of the lips. Materials used to record the lip prints were dark brown colored lipstick, cellophane tape and white bond paper. Lipstick was applied uniformly and Lip prints were taken on the glued portion of cellophane tape and then stuck on to a white bond paper. These lip prints were analyzed with magnifying lens and virtually with stereo microscope. On the analysis of the subject population, results showed Branched pattern Type II (29.57%) to be most predominant in the Gujarati population. Branched pattern Type II (35.60%) and long verticalType I (28.28%) were most prevalent in males and females respectively and Large Full lips were most predominantly present in both the sexes.

This study aimed to develop and to assess an algorithm to facilitate lip print visualization, and to digitally analyze lip prints on different supports, by superimposition. It also aimed to classify lip prints according to sex. A batch image processing algorithm was developed, which facilitated the identification and extraction of information about lip grooves. However, it performed better for lip print images with a uniform background. Paper and glass slab allowed more correct identifications than glass and the both sides of compact disks. There was no significant difference between the type of support and the amount of matching structures located in the middle area of the lower lip. There was no evidence of association between types of lip grooves and sex. Lip groove patterns of type III and type I were the most common for both sexes. The development of systems for lip print analysis is necessary, mainly concerning digital methods. [ABSTRACT FROM AUTHOR]

Introduction: Cheiloscopy is the study of lip print patterns which are individualistic and unique like fingerprints. Cheiloscopy is quite significant in forensic investigation like personal identification and sex determination. But unfortunately, crime detective agencies are still unaware of the importance of lip prints and are not being used in identification of criminals. Aim: To study different types of lip patterns in different quadrants of lip, their incidence in the given age group in relation to specific gender and uniqueness in personal identification. Materials and method: The study comprised of 150 subjects, aged 25-50 years from Chhattisgarh population, India. Lipstick was applied over the lip and lip impressions were taken on white bond paper with the help of cellophane tape and then visualized by magnifying lens. Analysis of lip prints were done according to Suzuki and Tsuchihashi classification. Result and conclusion: It was found that type I was the most prevalent cheiloscopic pattern among both genders. The least common lip pattern was type IV among entire sample study. No gender wise distribution was observed among lip print patterns. Lip patterns are unique for every individual and no two prints are similar to each other. Emphasis to be given for further studies using standard methods to evaluate the lip prints.

Background: In forensic identification, the mouth allows for a myriad of possibilities. Dental data is vastly used for positive identification of person, but nowadays other oral data such as palatal prints and lip prints are used for the process of identification, the object of which is to identify and register individuals for both civil and criminal purposes. Aim and Objective: To check whether there are any peculiar / common lip patterns among males and females and to establish lip prints as a tool for identification. Study Design: It's a cross sectional Prospective study. Method: It was conducted on the children who are studying in fourth standard to Tenth standard in the Government school at Pathancheru. 200 subjects were selected irrespective of their caste, religion, dietary habits & socio-economic status. Observation: Among males, it was found that intersected pattern was most common in compartments 1, 3 and 4, while the least common pattern in lip compartments 1, 2, was Undetermined. On evaluation of the lip prints of the females, compartments 1, 2 exhibited intersected pattern predominantly. However, in compartment 3 and 4, branched pattern was commonest. Conclusion: Lip prints are useful in personal identification and they differ from person to person even not similar in uniovular twins. Study showed that cellophane tape and lipstick can be easily used to retrieve lip prints. Lip print analysis is a process that can provides both qualitative and quantitative results.

Human identification process follows the principles of the theory of uniqueness. Fingerprint analysis uses the same theory to convince the court of law. Similarly the lip print is also unique to an individual and hence is nowadays very useful in the identification purpose. The external surface of lips has many elevations and depressions forming a characteristic pattern called lip prints, examination of which is known as 'Cheiloscopy'. The study group comprised of 15 male and 15 female subjects. The materials used were lipstick, lip-brush, cellophane tape, bond paper and a case performa. This study showed that the lip prints are unique to an individual and can be reliably used for the recognition of the sex of an individual. [ABSTRACT FROM AUTHOR]

Introduction: Cheiloscopy is the study of the furrows or grooves present on the red part or vermilion border of the human lips. The present study aims to classify the characteristics of lip prints and to know the most common morphological pattern specific to Mangalorean people of Southern India. For the first time, this study also assesses the association between gender and different lip segments within a population. Materials and Methods: A total of 200 residents of Mangalore (100 males and 100 females) were included of age ranging from 18 years to 60 years. Materials used to take the impression of lips included red lipstick, A4 size white bond paper and cellophane tape. The prints obtained were scanned using a Canon Image Scanner and stored in a folder on a personal computer. The images were cropped and inverted in gray scale using Adobe Photoshop software. Each lip print was divided into eight segments and was examined. Suzuki and Tsuchihashi's classification (1970) was used to classify the types of grooves, and the results were statistically analyzed. Six types of grooves were recorded in the Mangalorean's lips. Statistical Analysis: Association between gender and different lip segments was tested using Chi-square analysis in the given population. Results: In males, the groove Type I' was the highest recorded followed by Type III, Type II, Type I, Type IV and Type V in descending order. In females, Type I' was the highest recorded followed by Type II, Type III, Type IV, Type I and Type V in descending order. Conclusion: Males and females displayed statistically significant differences in lip print patterns for different lip sites: lower medial lip, as well as upper and lower lateral segments. Only the upper medial lip segment displayed no statistically significant difference in lip print pattern between males and females. This shows that the distribution of lip prints is generally dissimilar for males and females, with varying predominance according to lip segment. [ABSTRACT FROM AUTHOR]

Background: Personal identification plays an inevitable role in forensic investigation. Lip print is one of the evidences that can be left in the crime scene, which helps in identification purpose. Hence, the present study was undertaken to provide deeper inside view of use of cheiloscopy in personal identification, focusing on sex and age variability of lip print patterns in the population of Rajnandgaon city, Chhattisgarh, India. Materials and Methods: The cross-sectional study was conducted among 200 (100 males and 100 females) subjects of age 15-55 years, residing in different areas of Rajnandgaon city. The sex of the individual was determined as per the description given by Vahanwala et al. Frequency distribution and Chi-square test were used for data analysis by SPSS 16.0 V software. Results: The most common lip print pattern in entire population was Type I (27.5%). Very highly significant difference was found in the distribution of lip print patterns among males and females in the entire population, group I, and group III, respectively (P < 0.0001). The overall accuracy of cheiloscopy in sex determination was (high) 87.95%, 87.65%, 90.5%, and 80% in group 1, 2, 3, and 4, respectively. Conclusion: Thus, it can be concluded that lip prints can be used as one of the important forensic tools for personal identification on the basis of their age and gender variability among the populations.

Fingerprints are considered to be the most reliable criteria for personal identification. In the past decades, lip-print studies (Cheiloscopy) attracted the attention of many scientists as a new tool for human identification in both civil and criminal issues. The present study was undertaken to observe the correlation between lip prints and finger print pattern in sex determination and to determine the pattern predominance in a sample of 5000 individuals. The study was carried out in 5000 individuals in Department of Oral Medicine and Radiology of Maharishi Markandeshwar College of Dental Sciences and Research, M.M. University, Mullana. Of the participants, 2500 were males and 2500 females. Lip prints and finger prints of the right hand were collected then studied and analyzed statistically. For lip prints TSUCHIHASHIS Y. classification (1970) was followed; HENRYS classification(1897) was followed for finger prints. Whorls were of a high frequency in males, but females presented with a high frequency of loops. Type I, I', II lip print pattern was most predominant in females while Type III and Type IV was most predominant in males. The present study described in detail that for both males and females, the most predominant lip-print patterns showed an association with the respective predominant finger print patterns. The establishment of a database of Cheiloscopy and Dactyloscopyis recommended for all individuals in a certain locality, which could be used as a reference in civil litigations and criminal cases. Such studies may be useful particularly in Forensic science and in justice. [ABSTRACT FROM AUTHOR]

The last few decades have seen the development of the exaggerated importance of lip prints as another skin impression. Cheiloscopy deals with the examination of system of furrows on the red part of human lips and is an important tool in forensic science. Traditional lip stick produces a print that is easily identifiable. However, lip prints made without lip stick are invisible known as latent lip prints, requiring reagents that are more sensitive than conventional materials to locate and develop the invisible prints. In this paper the authors describe about the unusual techniques of cheiloscopy used in detection and development of latent lip prints. [ABSTRACT FROM AUTHOR]

Context: Lip prints are very useful in forensic investigation and personal identification. Like finger prints, even lip prints can be instrumental in identifying a person positively. Aims: Indians are closer to Mongoloids than to Caucasoids or Negroids as indicated by the phylogenetic tree. Most of the studies on lip prints are done in their own population. We have compared lip prints of Manipuris with other Indians (Aryans and Dravidians) who are both close to Mongoloid race and are genetically similar. Materials and Methods: A total of 100 students 50 males and 50 females were selected of whom 30 males and 30 females were of Aryan and Dravidian features and 20 males and 20 females showed the Mongol features. Study materials used were Red colored lipstick, Lip brush, Cellophane tape, White chart paper and Magnifying lens. The lip prints were analyzed by dividing them into eight compartments. Results: Analysis of lip prints showed that the most common and the least common pattern in both males and females (Aryans-Dravidians and Mongols) were the same, but the compartment wise distribution of the lip patterns was different. Conclusion: In the present study, it is established that there is no similarity of lip prints from one individual to another individual and between males and females. Regarding the comparison with Mongols, more studies with a larger sample size is necessary. [ABSTRACT FROM AUTHOR]

Introduction: Individual identification is a significant and difficult task in forensic search; it was based on logical values. A lip print is different in every living individual and does not change with time so it can be used as a tool in forensic investigations. The present work aimed to find out the correlation between lip prints and lip competence in the pediatric population of Davangere city. Materials and Methods: The study sample comprised of 103 children that is, 49 males and 54 females of aged between 4 and 14 years. The lip impression was made on a strip of cellophane tape on adhesive portion; it was then placed to a white bond paper. This serves as permanent record. In this study, we are followed the classification of patterns of the lines on the lips proposed by Tsuchihashi. For recording lip competence, we considered Ballard criteria. Results: Chi-square test was used to find out the degree of association between variables and to check out whether statistically significant differences exist. Conclusion: Lip prints are unique for every person and show differences according to the race and the ethnic origins of a person. The present study confirmed the distinctiveness of cheiloscopy but disproves any statistical correlation of lip print with lip competency. [ABSTRACT FROM AUTHOR]

Objective: To evaluate and compare the lip print patterns among Indian, Chinese and Malay population. Background: Cheiloscopy is an important tool used in forensic odontology for the identification of an individual. As lip prints are unique to an individual they can be used as evidence when obtained from the crime scene. They are mostly seen in cases of murder, rapes, and burglaries. Lip prints have the same value as dactyloscopic traces. Lip prints show variations between sex, twins and also races. The purpose of this study was to compare lip print patterns among subjects of Indian, Chinese and Malay origin. Materials and methods: The study was conducted on 185 students of Melaka Manipal Medical College of the Manipal University. The subjects were from 3 different races comprising of 61 individuals of Chinese, 63 of Malay and 61 of Indian origin. Lip stick was applied uniformly with the help of a lipstick application brush and were then recorded by means of a cellophane tape that was placed over the upper and lower lip. The scotch tape was then stuck to a white bond paper as permanent record with details of the subjects mentioned on it. The Pearson's Chi-square test was used to analyze the data. Results: The lip print patterns were compared among individuals of the three ethnic races. Pearson Chi-square test indicated that there was statistical significance between ethnicity and the lip print pattern Conclusion: The present study establishes that there is no similarity of lip prints from one individual to another of different ethnic races. More studies are to be done to further ascertain the most predominant lip print patterns among the Indian, Chinese and Malay population. [ABSTRACT FROM AUTHOR]

Background: Cheiloscopy is the study of furrows and grooves present on the red part, or the vermilion border of the human lips. The type of groves is unique for an individual and can be used for person identification. Aim: The aim of this study is to ascertain whether the uniqueness of lip print (LP) can help in identifying a person. In addition to evaluate the comparison of LP types and blood groups was taken up to see if there is any correlation between the two. Materials and Methods: A cross-sectional study was conducted on 200 participants (77 males and 123 females), aged between 25 to 45 years, to determine any correlation between LP types and blood groups. These lip patterns were analyzed and interpreted using Tsuchihashi's classification and later associated blood group matching was performed to determine the predominant LP type with the ABO and Rh blood grouping system. Results: The present study showed a positive correlation between LP pattern and blood group among males and females. Thus, distribution of LP patterns, and ABO blood groups might help in the identification of an individual. Conclusion: Since LP and blood group are unique for a person. Hence, cheiloscopy along with blood group can play a vital role in person identification. [ABSTRACT FROM AUTHOR]

Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. This is unique for individuals like the finger prints. Lip prints are hereditary yet considered to be individualistic, each possessing their own unique characteristics. For this reason it is safe to suggest that lip prints can be included in the forensic sciences arena as a legitimate means of identifying persons of interest connected with criminal activity. Lip prints thus hold potential promise as an instrumental tool in forensic odontology. The purpose of this article is to give an insight into this branch of forensic odontology with an emphasis on its historical background, techniques of recording it and its future perspectives.
