Although almost all studies exclude lip conditions because they would affect furrow patterns, some authors maintain that they should be considered temporary or permanent disabilities, all of which require further research in this context.We present a study in which we associate lip conditions with lip print patterns to associate both morphological elements for fieldwork purposes. Fifty-seven women and 48 men aged between 19 and 38 years who resided in Temuco (Chile) were included. The lip conditions and their prints were recorded, and an analysis, comparison, evaluation, and verification protocol (ACE-V) for lip prints was applied. Of the participants, 27.4 % had healthy lips, while 71.7 % had some type of condition. Although patterns related to temporary and permanent lip conditions were recognized in the lip prints in a non-significant way, the diagnosis of "healthy" or "altered" lip status could be made significantly by a calibrated examiner. Although these conditions do not represent identifying variables without empirical studies to validate them, they can affect the quality of the evaluated lip print; therefore, they should be recognized during the analyses considering the prevalence of these conditions.

Background: Endless ink and pixel space have been spent to validate the use of cheiloscopy classification systems in the field of identification. It is becoming evident that lip-print patterns may provide indications about an individual's gender, race, occupation, habits, blood type, and paternity. Over the course of time, much data have been collected on a substantial population in this field. In the present study, we strive to see how well a noble total lip scoring (TLS) system works in identifying a person's gender among the College of Dentistry students. We also quantified the total groove score (TGS) and compared it with each quadrant for better authentication of the set study design. Materials and Method: A cross-sectional descriptive study was conducted among 60 dental students (30 males and 30 females), with an age range of 18-30 years. Lip prints were recorded using the writing pad method and subsequently digitalized by capturing the images using Adobe Photoshop CS 6 Extended Version, counted and summed up, quadrant-wise, in both upper and lower lips. The TLS and TGS between males and females were statistically calculated using the Jamovi project. Results: The mean value for TLS for males (n = 402; SD ± 92.1) is higher than that for females (n = 348; SD ± 86.1). The correlation matrix applying a non-parametric test for non-continuous data using Spearman's ratio inferred a statistically significant correlation (-0.354) with a P-value of 0.005 for TLS, whereas a correlation (-0.162) of TGS with gender was not so significant with a P-value of 0.217. Conclusion: Our study proved the uniqueness of applying TLS as a novel approach to gender identification. The study revealed that males had a statistically higher lip score than females. Clinical Significance/Future Implications: Being unique, our study inferred the importance of TLS, which needs to be explored in detail for applying, evaluating, and validating its accuracy in forensic research that can help for errorless investigations as full-proof evidence in court.

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.

Cheiloscopic examinations have long been conducted, and many scientists have reported the usefulness of cheiloscopy for personal identification with a characteristic and individual pattern of furrows on the vermilion lip. For almost 40 years, research conducted in Poland has determined the patterns of these furrows and the separation and development of their individual features. This was the basis for forming expert opinions and presenting them in court as evidence. In Poland, cheiloscopic expertise is performed and the results of precise procedures that are accredited and assessed serve as evidence. Although the legal system in Poland (continental system) is completely different from the American system, cheiloscopic expertise was also assessed in detail according to the American standards of evidence. This narrative review presents the problem of cheiloscopic expertise as a scientific and practical issue and provides a brief historical overview of this field and the foundations of the Polish cheiloscopic identification method. We conclude that Poland has sufficient historical background and a robust development of cheiloscopy in the field on a scientific and legal basis; however, due to its reports being in the Polish language, its absence from the most relevant specialized literature, or simply a lack of cooperation between countries and experts, the country has unfairly been left out of the discussion. We believe that a new look at the Polish contribution to lip print identification is necessary to reinsert this topic into the current discussion of a new identification paradigm.

Background and Aim: Lip prints just like fingerprints follow unique patterns in every individual and are said to vary significantly even within the same family. Lip prints can be recognized from 6th week of intrauterine life and remain unchanged throughout their life. The objective of the present study was to evaluate personal identification through lip print patterns with additional reference to twins and members of the same family. Materials and Methods: Lips of 75 males, 75 females, and 30 twins were studied in various quadrants. In addition, the pattern in the middle 10 mm of the lower lip was also evaluated to note the pattern distribution and dominance of the type of pattern in different genders. Lip print patterns in five families across three generations (eight members each of the same family) were observed for the existence of inheritance of patterns from their ancestors. Results: Among males and females, the most common pattern in the middle 10 mm of the lower lip is Type III (34.66%) and Type IV (32%), respectively. In the middle 10 mm of the lower lip, 33.33% of twins have similar lip patterns but with differences in its arrangements. The result showed different lip print patterns even in twins and among the members of the same family across three generations, with some similar patterns which suggesting hereditary influences in lip prints. Conclusion: In the present, we can see that lip prints are unique and permanent for every human being even among twins and individuals of the same family. [ABSTRACT FROM AUTHOR]

Purpose: Lip prints are unique and have potential for use as a human identifier. The purpose of this study was to observe possible cheiloscopy differences of individuals with and without parafunctional oral habits such as smoking, vaping, playing a wind instrument or using an asthma inhaler. Methods: This IRB approved blinded cross‐sectional observation pilot study collected lip prints from 66 individuals, three of which were excluded. Participants cleansed their lips, then lipstick was applied to the vermillion zones of the upper and lower lips. Adhesive tape was applied to the lips and prints were transferred to white bond paper for viewing purposes. Each set of included lip prints was divided into quadrants and dichotomized into a group of those with an oral parafunctional habit or with no such habits. Each quadrant sample was then manually analysed and classed according to the gold standard Suzuki and Tsuchihashi system. Results: A total of 252 dichotomized lip print quadrants (with habits n = 76, 30.2%, and without habits n = 176, 69.8%) were analysed. Type II patterns were the most common for examined quadrant samples; however, no statistically significant differences (Pearson's chi‐squared test, p = 0.366) were observed between pattern classifications of samples with and without parafunctional oral habits. Conclusions: There is no statistically significant difference of lip print patterns between individuals with and without parafunctional oral habits. Further research on populational variations is needed for cheiloscopy to aid in human identifications. [ABSTRACT FROM AUTHOR]

Introduction: Cheiloscopy is one of the investigative methods that utilises the anatomy and morphology of lips to identify individuals by their lip prints. Lip prints are a distinctive pattern made up of ridges and grooves on the labial mucosa, or sulci labiorum; cheiloscopy is the study of such patterns. Material and Methods: The study group comprised of 50 males and 50 females aged between 18 and 25 years in the Department of Forensic Medicine and Toxicology, Jawaharlal Nehru Medical College, AMU, Aligarh for a period of 1 year i.e., from August 2021 to September 2022. Results: Each individual lips were divided into 4 regions- upper right, upper left, lower right, and lower left and a total of 400 lip regions (100x4) were assessed for 6 types of lip groove patterns- Type I, Type I', Type II, Type III, Type IV, and Type V as per the Suzuki and Tsuchihashi classification. The most common type of lip print pattern in males was Type III (32.5%) while in females it was Type II (36%). Conclusion: Lip prints are distinctive to each person and can be used to identify a person and ascertain their gender. [ABSTRACT FROM AUTHOR]

Introduction: In criminal investigations and court cases, as well as in civil identification and civil litigation, forensic dentistry is essential. The analysis of lip prints is among the least invasive and cost effective way of human identification. Lip prints like blood groups can add as an adjunct in the investigations where in situations of mass disasters.The aim of the study was to assess and corelate lip pattern and blood groups in 100 study participants. Materials and Methods: A total of 100 participants, 50 male and 50 female were included in the study. The method followed was according to Costa and Caldas Technique, and the classification method followed was according to Suzuki and Tsuchihashi Y et al. Result: Type 1 and Type 4 showed correlation with O positive blood group. Type III was seen with a predilection with B positive blood group. It was further observed that type 1 lip print type was seen more in males when compared to females. Females showed both Type 1 and Type 4 lip print. Discussion: The present study showed a trail of association with Type 1 and 4 in O positive blood group subjects. The Type 1 was seen in males and females, but females were more associated with Type 4 lip print. This study was in accordance with the results found by Kersarwani et al. in 2021. Conclusion: Though the present study showed no statistical significance it can be carried out with a larger sample size. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study is to find out the difference in lip print pattern among live and dead individuals. Materials and Methods: A total number of 200 individuals (100 live and 100 dead individuals) were taken for the study. The live individuals were between 18-25 years of age and for dead individuals the lip prints were taken between 24-48 hours of death from the dead body. The lip prints from live individuals have been taken by traditional lipstick paper method described in the literature while for dead individuals it was taken by DIGITAL METHOD focussing camera on the lips. Results: The lip prints for live and dead individuals were studied by Suzuki & Tsuchihashi classification. In live individuals the lip patterns were Type I, I', II, III, IV and V while in dead subjects the same lip patterns of Type I, I', II, III, IV and V were found with significant difference. Conclusion: The study of lip prints for dead individuals has been for first time in the field of forensic odontology and this study is first of its kind in the academic literature. However, there is need for further study to be done in different parts of the world for different dead individuals lip print patterns. [ABSTRACT FROM AUTHOR]

Hereditary lip prints have been studied by several researchers. However, the literature shows no consensus among the scientific community regarding this topic. Therefore, the aim of this study was to conduct a systematic review to gather evidence to clarify whether the surface structure of lip prints is hereditary and, consequently, if a familial relationship between individuals can be established through the analysis of lip prints. The systematic review was performed following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) 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 of each study was assessed and applied as additional inclusion or exclusion criteria. The results of the articles eligible for analysis were synthesized by a descriptive approach. In the seven included studies, methodological variations, including the definition of similarity, that contribute to the heterogeneity of results were identified. The data gathered allowed to conclude that there is no strong scientific evidence to support the hypothesis of the existence of heredity in the surface structure of lip prints, since it was not proven that similarities between parents and children occur systematically in all families.

Background: The knowledge and importance of blood groups emerged from transfusion medicine and its relation with certain malignancies has been proven. Its importance in forensic medicine was brought to light when its association was found with the distribution of finger patterns. Thus, few studies exist proving the relationship between dactyloscopy and blood groups. Cheiloscopy on other hand is the study of the irregularities present on the lips forming a unique arrangement called the prints of the lip. Aim: Our paper aims at elucidating any unique combination if any that exists between prints on lips, prints of fingers, and blood grouping in a specific population, which might help in the identification of an individual. Materials and Methods: A total of 100 subjects of age varying from 15 to 40 years were included in the study. Subjects comprised of 50 males and 50 females. All the subjects were examined and their prints of lips along with prints of their fingers were taken. Blood groups were determined for each patient using the ABO system. Results: Type I was found to be the predominant pattern of lips and whorl arrangement was the most recorded type of fingerprint in males whereas Type II arrangement along with loop prints of fingers was most observed in the case of females. The most common blood group in males was B+ and in females was O+ . Correlation between three parameters was obtained by Pearson correlation statistical analysis. Conclusion: The prints of the lips and fingers of an individual have never been similar and they tend to remain the same from a person's birth until his death. An association between the three things of an individual that is prints of lips, fingers, and his blood group has been tried to be elucidated through the present research to aid in forensic identification.

Cheiloscopy may not be as well-known as other techniques of identification, such as fingerprint or DNA analysis, but it has its own impact in the appropriate circumstances. Cheiloscopy has been recognized as an important tool for human identification. A manual approach of studying lip prints was utilised by many researchers (magnifying glasses). Nonetheless, the current study relied solely on a mobile phone camera to visually capture lip prints for sex determination. 377 samples of lip prints were analysed with Adobe Photoshop software and classified into six different types of lip print patterns, according to Suzuki and Tsuchihashi classifications. Lip prints were divided into six sections including upper left, upper middle, upper right, lower left, lower middle and lower right. Pearson's Chi-square test revealed significant differences between male and female lip prints (p < 0.05) among the Malaysian Malay population of the Klang Valley, with Type V (irregular pattern) lip prints being the most prevalent. In comparison to magnifying glasses, our studies proved the ability to record and examine lip prints utilising a digital approach. [ABSTRACT FROM AUTHOR]

Objective:Human identification plays a vital role in crime investigation. Lip impressions are one of the evidences that may be left at crime scenes, which aid in the precise documentation process. The objectives of the current systematic review and meta-analysis (CMA) are to provide a deeper understanding of the use of cheiloscopy as a reliable method in sex identification and to establish the predominant lip print pattern found among different genders using the classification proposed by Suzuki and Tsuchihashi. Study Design: A systematic review and meta-analysis Result:The most likely lip print present among males in the selected studies was type III (30.2%), followed by type II (29.9%), and type I comprised one-fifth of the sample size (21.1%). While among females, almost one-third were reported with type I lip print pattern (36.5%), followed by type II (28.9%). Furthermore, the results showed that the rate of type IV lip print pattern was similar between males and females (18.3% and 13.4%, respectively; P<0.059). Conclusion: Along with the other traditional methods of human identification, this study proved the distinctiveness of lip print (cheiloscopy) as an adjuvant tool for human identification and sex determination and no identically similar lip-print patterns appeared in two subjects. Further studies with larger sample sizes, different methodologies of assessing lip print are needed to confirm the current findings. [ABSTRACT FROM AUTHOR]

Background: Identification of human beings forms the basis of any criminal investigation. Lip print study, also known as cheiloscopy is the study of patterns formed by the ridges and grooves on the external surface of lips. This study aims to classify lip prints and study its correlation to sex. Methodology: 205 student participants who volunteered were included in this study of which females were 123 and males were 82. A food safe pigment was applied to the lips. Over this pigment, the glued portion of the cellophane tape strip was placed and the subject was asked to make a lip impression in the normal rest position of the lips by dabbing it in the centre first and then pressing it uniformly toward the corners of the lips. The cellophane strip was then stuck to the white chart paper for permanent record purpose, then visualized by magnifying lens and analysed quadrant wise. Conclusion The most common lip print in the upper lip was found to be type 3 and in the lower lip was found to be type 4. Statistically significant difference with respect to sex was observed in first quadrant only (p = 0.01) and not in others. [ABSTRACT FROM AUTHOR]

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]

Introduction: Cheiloscopy is the forensic investigation method of utilizing lip prints for personal identification. It has been proved that lip prints are unique for each individual and can be of use in criminal investigation. Latent lip print can be seen on surface such as glass, cigarette butt etc. Many studies have shown a number of ways to develop latent lip prints using fingerprint powder, Sudan III, Oil Red O etc. Aim: The present study was conducted to compare the efficacy of three different materials to develop latent lip print -- Fullers Earth (Multani Mitti), Indigo and Vermillion (Sindoor) and to see under the stereo microscope. Material and Methods: A total of 60 individuals belonging to the age group of 18-34 years were included in this study. Latent lip prints of lower lip were recorded and consequently developed by Indigo blue, Vermillion and Fullers earth. Subsequently a standard lipstick print was taken from the same subject and compared. Subjects having lip deformity, active lesions and surgical scars were excluded from the study. Each sample was assessed and graded according to Renauds classification. Results: Lip prints were analysed and compared for efficacy of reagent. Statistical analysis showed significant results between vermillion and indigo blue, and between indigo blue and fuller's earth. However no statistically significant result was observed between indigo blue and fuller's earth. [ABSTRACT FROM AUTHOR]

Introduction: "Cheiloscopy" deals with the identification of humans based on lip traces or prints. The patterns of lip prints are unique for every individual and do not change with time and can be used for the purpose of forensic investigations. Material and Methods: The sample size of 200 (100 males and 100 females) aged 18years and above have valid identification proof. Lip prints were collected and analyzed as per Suzuki's classification. Result: Partial length groove running vertically across the lip (Type I') is the most common (28.5%) lip print that is seen in the whole lip of the New Delhi population in visible lip prints. Conclusion: The study was conducted with the aim to determine the most common lip print pattern on the whole lip. According to the findings, each individual's lip print is unique, and the lip print pattern can be utilized as an additional means of identification of an individual. This paper reviews that lip prints have no racial differences and thus cannot be used for population identification. [ABSTRACT FROM AUTHOR]

Objective: To assess for any peculiar lip prints in relation to the lip shapes of individual, and determine the most common lip print type among the members of biological families. Study Design: Descriptive study. Setting: Department of Forensic Medicine & Toxicology, Women Medical & Dental College, Abbottabad. Period: January 2018 to June 2018. Material & Methods: A total of 216 individuals (father, mother, both children's), who underwent descriptive study of lip impression collection without any anesthesia or drug, were enrolled into the present study. Father, mother and two babies of each family were selected. Lip prints of Father, mother and both babies of each family were recorded. Each lip of 54 offspring's was compared with the corresponding lip of his/her father mother and other baby. The segments of each lip of the offspring's that matched/ resembled with either of father mother and biological babies were recorded. Results: Out of 54-total families, biological babies of 19(35.18%) families observed resemblance with father, whereas biological babies of 35(64.81%) families observed resemblance with mother. There was no definite identical lip print observed in any of the children. Furthermore, the prevalence of Type II lip prints was higher type present in males and in females. We observed that lip shape 7 was the most frequent lip shape type in most of individuals. Conclusion: Lip prints of study participants did not clearly match with each other, evenly distributed in both genders and distinctive similar to finger prints. The data did not show any specific association of the lip print type with lip shape. It is considered feasible to apply lip prints features in personal identification. [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: The human lip holds a considerable variation in the groove pattern and have been used as a tool for identification as commonly found on many surfaces (cups, glasses, cigarette butts, etc.). This study was done to identify the pattern among the population and also to evaluate the relevance of the impression left on different surfaces with the standard lip prints using superimposition technique by Adobe Photoshop 7.0. Material and Methods: The present study is comprised of 100 subjects of Lucknow, Uttar Pradesh between 18-30 years. Results: The predominant lip print patterns in male subjects are (TYPE I') followed by (TYPE III) whereas in female subjects, it is (TYPE II) and (TYPE I') and (TYPE V) is the least and rarely found in both of the male/female samples also white clay cups had shown highest percentage of matching with first attempt prints, while steel tumblers had the lowest. Similarly the results were observed during the second attempt. Conclusion: The present study showed that the lip prints have a great potential to be used as an added measure in sex determination. Further more lip prints found on white clay cups were most suitable for super imposition. [ABSTRACT FROM AUTHOR]

Background: The wrinkles and grooves visible on the lips form the characteristic pattern of an individual and imprints produced is termed as "lip print." The study of these prints is known as "cheiloscopy." Variations in patterns among males and females could help in sex determination. Lip prints, therefore, can constitute material evidence left at a crime spot, equivalent to fingerprints. These patterns are heritable and are believed to be unique and permanent. The lip prints of parents and children and those of siblings have been shown to have some similarities. The influence of inherited lip print patterns among family members is still a new concept and studies are scanty in literature. Objectives: The objectives are to determine the most common patterns and gender-wise distribution among the study population and to analyze the inherited lip print patterns from parents to their offspring. Materials and Methods: Lip prints of 30 families were obtained using lipstick and cellophane tape. Based on criteria given by Suzuki and Tsuchihashi, patterns were recorded and analyzed from four quadrants of the lips using a magnifying lens. Results: The positive resemblance of lip print patterns from parents to their offsprings showed statistically significant resemblance in one quadrant and rest of the three quadrants showed no significant association between parents and offspring. Conclusion: Positive resemblance among the family members can be attributed to the genetics and inheritance. Lip print can be considered as an auxiliary method of identification.

Aim The present study was conducted to assess gender identification and this can be used as a reliable tool in the identification of an individual at any judicial process. Materials and Methods This study comprised of 82 dental students (42 females and 40 males) with age ranging from 19 to 21 years. Lip prints were recorded with the help of a cellophane tape strip and analysed according to Suzuki and Tsuchihashi classification criteria. Results The mean age distribution among males was 20.07 ± 0.81 where as in females it was 19.78 ± 0.73. Distribution of different patterns in upper lip vertical patterns was very prominent when compared with reticular, branched and intersecting. Distribution of different patterns in lower lip branched patterns was very prominent when compared with reticular and verticals. Comparing between upper lip with lower lip pattern wise there was no statistically significant. Compared different patterns in relation with lower lip the values showing stastically significant (p≤0.05). Summary and Conclusions Lip prints or Cheiloscopy can be used an individual identification. The results obtained in our study do not show any evidence that cheiloscopy can be used as gender identification. This could be because of smaller sample size, we need larger sample to give consolidated evidence related with gender identification. [ABSTRACT FROM AUTHOR]

Cheiloscopy is the analysis of the lip prints, grooves, thicknesses, angles, and other structures of the lips that differentiate each individual in a similar way to biometrics. This study aimed to observe these lips characteristics and to verify if there is a labial pattern among the students of the UFVJM Dentistry course of that distinguishes them in genders. Fifty students were selected, photographed, and had their samples collected by printing their lips on transparent tape with wine 01 lipstick, evenly distributed with the aid of a flexible rod and attached on white paperboard and later classified for obtaining the data required for statistical analysis. When analyzing lip thickness, it was found that most of the students had thick lips - 78%, whereas regarding the position of the labial commissure, 50% of the students presented horizontal disposition. Through the classification system of Suzuki and Tsuchihashi the types of furrows were classified, type II being the most common in this research. Despite the evidence that, among the volunteering students, female lips are thinner than male lips, there were no statistically significant differences between men and women. However, there is a need for more studies that seek to validate and disseminate this technique in a standardized way so that it is a complementary tool in Forensic Dentistry. [ABSTRACT FROM AUTHOR]

Background: A latent lip print can be important evidence, and specific substances are needed for the development of a latent lip print. However, collecting the lip print may difficult due to people who have sensitive skin with lipsticks and almost men who do not wear lipstick. Moreover, the enhancement methods of latent lip print are still lack of standardization and consistency. Aim: To develop a new staining method for the study of the lip print patterns Thai population. Method: The latent lip prints were collected from 24 males and 24 females. The ability of Roselle extract was investigated for developing latent lip prints on cigarette paper. The developed lip print was used for the morphological pattern analysis using Suzuki and Tsuchihashi’s classification criteria combined with Autodesk SketchBook. Result: The results revealed that Roselle extract exhibited potential as a staining dye for the development of latent lip prints on cigarette paper. Among the 24 males and 24 females, Type I was found to be most common and was present in 54.55% of the volunteers, followed by Types I’, II and IV (21.12%, 14.58%, and 9.03%, respectively). The least common patterns were Types III and V, each represented in 0.35% of the total volunteers. Conclusion: latent lip print could be used for study of lip print pattern by stained with Roselle extract. Moreover, a digital method using Autodesk SketchBook serves as an alternative method that provides ease in storing and identification of lip print pattern. [ABSTRACT FROM AUTHOR]

Cheiloscopy (quiloscopy) is a method of identification of a person based on characteristic arrangement of lines appearing on the red part of lips. Lip prints are unique to an individual, and persist in their characteristics over a period of years. They are like fingerprints reliable method for identification. The aim of the study was to find out various patterns of lip prints and the commonest pattern observed in both males and females. Materials and method: The study was carried out on 200 individuals residing in suburban area in Dakshina Kannada District, of ages ranging from 12-60yrs of both sexes after taking consent. The present study was carried out from 2013 to 2015.The materials used were dark colour lipstick, bond paper, cello tape. Results: The common pattern of lip print observed was Type I in the entire study population in both males and females. In Dakshina Kannada however it was not statistically proved significant. There was no significance between patterns and gender. [ABSTRACT FROM AUTHOR]

Personal identification is of vital importance in forensic odontology for ethical, humanitarian and criminal enquiries. The applicability of Cheiloscopy ( study of pattern of lip print), one of the easiest tools available in individual and medicolegal identification, is an area of extensive research in recent years. With the objective to investigate the uniqueness of lip patterns in relation to gender and blood groups, this study was conducted on 100 subjects, which included 50 males and 50 females. The lip prints obtained were studied by applying Suzuki and Tsuchihashi’s classification.Type 2 (37%) was the most common lip print type in males and Type 3 (38.5%) was the most common lip print type in females. The Lower lip print can help in gender determination. No significant statistical correlation was found between the lip print patterns and blood group. Along with the traditional methods of identification like fingerprint analysis,Cheiloscopy can also be helpful in the identification of a person.However, the utility of the same in forensic medicine still remains largely untapped and unacknowledged. Similar studies with larger sample sizes are required to obtain statistically significant reports thereby allowing a more impactful emergence of lip print patterns usage in forensic analysis.

Introduction: Cheiloscopy is the study of lip prints. Since the inception of the technique, the techniques is being used to evaluate the individual identity and its association with sex determination. As the blood stains may also be present at a crime scene, further studies have also been done to evaluate the association of common blood group pattern with lip prints. Aims and Objectives: To study the patterns of lip print and its association with blood group and gender in adults. Methods: In this prospective observational study, data were collected from 150 subjects (75 males and 75 females). All the subjects fulfilling the inclusion and exclusion criteria were in the age group of 18-30 years. In this study lip print pattern samples were collected by paper fold method and blood group samples were collected and both were analysed according to Tsuchihashi classification and Landsteiner’s classification respectively. Results: A The predominant lip print pattern found in males, females and both the gender together was Type 1- complete vertical in both upper and lower lips. Predominant blood group found in this study was B+ve. Most frequent lip print pattern found in all blood group types was Type 1- complete vertical. Conclusions: Our study revealed an association between distribution of lip print pattern and gender. There was no correlation found in between blood group types and the cheiloscopic patterns. Further studies in different populations with large sample size are required to obtain a more definitive picture and statistical significance of this correlation. [ABSTRACT FROM AUTHOR]

Cheiloscopy is the branch of forensic dentistry studying the patterns and the systems of the lips' grooves for identification purposes. Different authors have studied different ethnic population but no research has been carried out specific to the Italian population. This study aimed to describe the pattern and the system of lip grooves in an Italian population composed of 96 subjects. The lip prints were taken as follows: a thin film of lipstick was applied onto cleaned and dried inferior and superior lips. The impressions of the lips were taken using a transparent adhesive tape. The grooves were identified and classified according to the classification of Suzuki and Tsuchihashi and a pattern was assigned. Sixty-eight different patterns were detected in the superior lips and 53 different patterns in the inferior lips. The most frequent pattern was the III-IV-IV-III and II-I-I-II for superior and inferior lips respectively. Within the limit of the sample size, the morphological analysis of the lip-prints confirmed their potential uniqueness in an Italian population. [ABSTRACT FROM AUTHOR]

Identification plays a major role in crime investigation. One of the most effective methods of identification are fingerprints. Like fingerprints, lip prints are also unique for individuals and remain the same throughout life. They are not influenced by environmental changes, trauma and diseases. The uniqueness of lip has been proven by researchers by using shape analysis and colour information. Lip prints can also provide some important information in crime investigations and have the ability to distinguish individuals and are used in human identification purposes. Human lips recognition is one of the most emerging methods of human identification that originates from forensic and criminal practice. Lip prints are captured by police technicians and further analysis provides valuable evidence. The use of lip prints first started in 1950 and researches were carried out in 1970. The wrinkles pattern on the lips has individual characteristics like fingerprints. Cheiloscopy is a forensic investigation method that deals with the study of elevations and depressions which form a characteristic pattern on the external surface of the lips. This is unique for individuals. Lip print recording is used in forensic investigation that deals with identification of humans, based on lip traces. Lip prints can be a basis for conclusion such as sexes, habits and character of that event. At a crime site lip prints can either be visible or latent. Print produced by a traditional lipstick is easily identifiable. Latent print investigation is important in resolving any criminal act. Latent lip prints are invisible prints and can be identified by using fingerprint powder. Long lasting lipsticks produce prints that are invisible and require reagents to develop the prints. The porous and multicoloured surfaces are the surfaces in which a print is difficult to identify and cannot be easily seen. Cups, glasses, tissue papers and napkins may have imprints of the suspect's lips. [ABSTRACT FROM AUTHOR]

Lip print is an anatomical character of the human lips. In forensic identification, lip print patterns can lead us to important information and helps in person's identification. The grooves present on human lips (Sulci labiorum) are unique to each person and can be used to determine identity. Fingerprints, post-mortem reports and of late, DNA fingerprinting, have been successful in person identification in the field of forensic science. Just as in these method, lip prints can be instrumental in identifying a person positively and can be used to verify the presence or absence of a person at the scene of crime. Cheiloscopic techniques have an equal value in relation to other types of forensic evidences for personal identification. Material and Method: The study was conducted on 100 students of age group 18-25 yrs. Lip stick was applied on each individual and the lip-print was obtained on a paper. The lip impression patterns were studied, classified and recorded using magnifying lens with light. Result: Lip patterns are unique for the individual and no two patterns are identical to each other. In study population,Type III pattern was most common in male while In females predominant pattern was type I. Thus in medico legal case, due to clear differentiation in sexes it is easy to identify person and gender. Conclusion: Cheiloscopy can be reliable method for personal identification and gender dimorphism. [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 patterns are referred to as unique to each individual, but controversy exists surrounding twins. In this study, the lip prints of 19 pairs of monozygotic and 47 pairs of dizygotic twins were studied. The left lower lip was photographed and the furrows were classified using Renaud's classification. Results showed the same lip pattern was found only in one monozygotic pair (5.3%) and in 4 dizygotic pairs (8.5%), and no significant statistical differences were found between groups (p>0.05). In monozygotic twins only type C furrows presence displayed statistical significant differences (p=0.034). As for dizygotic twins, there were statistical significant differences in the frequency of type A (p=0.005) and type G furrows (p=0.018). As for the most common types, both groups displayed a higher prevalence of vertical furrows (type B: 97.4% and 96.8%, type A: 86.8% and 87.2%, in monozygotic and dizygotic, respectively). The least frequent furrow type was type I and type E in monozygotic (2.6% and 5.3%, respectively) and types E, F and I, in dizygotic (6.4%, 7.4%. and 7.4%, respectively). Our results seem to point out that lip print patterns should be useful carefully in twins' identification. [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]

Background: The study of lip prints, is commonly applied in forensic odontology and it is known as cheiloscopy. The term cheiloscopy was derived from Greek words, in which "cheilos" means lip and "scopy" means to examine. In general, cheiloscopy is define as a method of identifying an individual based on the arrangement of lines seen on the red part of the lips or a science dealing with the various line appearing on the red part of the lips. The pattern of wrinkles and grooves that are present on the lips has distinct characteristic features of an individual which are almost similar to the fingerprints. It also will not change throughout the life. Therefore, it can be used for personal identification and sex determination. Aim: To investigate lip print pattern in males and females and to evaluate them between Malaysian and Indian population. Materials and Method: There were 40 participants of both gender. 20 of them are from the Malaysian population and another 20 people are from the Indian population. Each participant was instructed to clean their lips with a clean white cloth, before taking the lip print. This was followed by the application of dark coloured lip stick on lips by using the lip stick applicator. Cellophane tape was used to take the negative impression of the lip pattern. The glued portion of the cellophane tape was placed on the lips by giving a light pressure beginning from the centre of the lips till the corner of the mouth. Then, the impression was transferred to a clean white paper and seen under the magnifying glass. Results: Type I lip pattern was commonly seen in Indian population, followed by type III, II and IV. Whereas for Malaysian population, type III was most common followed by type I, II and IV. There was significant difference between both population. In this study, it showed that type I was the most common lip print pattern seen in both Indian and Malaysian population for females. Whereas for male, type III was more common in Malaysian population, and both type III and IV were more common in Indian population. Conclusion: There was no significant difference in both population according the general distribution of lip print pattern. There was no correlation or similarity of lip print patterns between each participants in both population. Thus, cheiloscopy can be used for sex determination and also personal identification.

Personal identification is of paramount importance in the forensic odontology for ethical, humanitarian and criminal investigations. In forensic odontology, scientific methods using DNA is considered to be the gold standard method of identification; however, it's expensive and time-consuming approach have circumvented the need for less expensive and faster methods of identification. The latest inexpensive approach of quantifying evidences for identification of suspect in crime is using lip print, fingerprint, palatal rugae & blood grouping and this has gained tremendous importance in the present days. Hence, the aim of the present study is to correlate and compare Cheiloscopy, Dactyloscopy and Palatoscopy with blood group and Rh factor. Method: A total of 200 dental students between the age group18 to 25 years were included in the study. Lip print, finger print and palatal rugae patterns with ABO blood groups were collected and compared using Chi square test. The data was analysed using SPSS version 10.0 statistical package. Results & Conclusion: Statistically significant correlation existed between lip print and ABO-Rh factors (χ2statistic = 37.56, p value <0.05) and between finger prints and ABO-Rh factors (χ2 statistic = 30.6, p value < 0.05). No association was found between palatal rugae with ABO-Rhesus blood groups (χ2 statistic = 17.71, p value >0.05). [ABSTRACT FROM AUTHOR]

Background: The wrinkles and grooves on the labial mucosa called sulci labiorum forms a characteristic pattern called as lip prints. The study of lip print is cheiloscopy it is used as an identification tool in the forensic department these days since lip prints are unique as fingerprints in each individual’s. Aim: The aim of the study was to compare the lip prints of North Indians and South Indians and to analyze its uniqueness. Materials and Methods: The study group consists of 100 people, which included both 50 North Indians and 50 South Indians. The subjects had no lesions on their lips and they were not sensitive to lipsticks. A single coat of lipstick was applied on the subject’s lips evenly, not too thick. The subjects were asked to keep their lips in a closed and resting state, and a strip of cellophane tape was used to take the lip print impression. The grooves and furrows in the impression were clearly examined using a magnifying glass, and the type of lip print was identified. The number of lines and furrows, length, branching, and combination was noted and recorded. Then, the lip prints were compiled, analyzed, and interpreted. Results: Lip prints are unique like our thumbprint and in correlation of lip prints among North Indians and South Indian, Type 2 was dominant in North Indian upper right lip; Type 1a was dominant in South Indian. Type 1a was dominant in both North Indian and South Indian upper left lip. Type 2 was dominant in both North Indian and South Indian lower right lip Type 2 was dominant in North Indian lower left lip; Type 1a was dominant in South Indian lower left lip. Conclusion: Lip prints are unique and it can be used for identification purposes. Among North Indians and South Indians, Type 2 and Type 1a were most predominant in both the population.

The most common lip print pattern was Type I (66%), second was Type II (17.3%), then Type IV (7.1%), after that Type III (5.1%), Type I'(2.5%) & last was Type V (1.7%). Conclusion: The most common lip print pattern in females of Punjab, Pakistan is Type I while the least common is Type V. [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]

Introduction: Cheiloscopy is a study of pattern of lines on the red part of human lips, which are unique for each individual, just like the other identification methods e.g. finger print and teeth and bite mark etc. It can be very supportive in crime scene investigation when probability of retrieving other evidences is sparse. Apart from personnel identification, lip prints are also known to fix the gender of an individual. Aim: The aim of the present study was to document varieties of lip prints along with an objective of deciding its uniqueness in terms of identification of an individual. Material and method: This study was conducted on 200 medical students of Parul Institute of Medical Sciences and Research, Parul University, Vadodara, Gujarat. In which 100 male and 100 female medical students were included. The lip prints were obtained by application of lipstick evenly on both lips, prints were obtained on thin bond paper and on plain glass slide. Lip prints obtained on plain glass were retrieved and matched with the first one by two examiner to identify each person on the basis of it. Result: Lip prints of 187 of 200 individual were correctly matched, thus identification of the person was successful in maximum students. Conclusion: The study revealed that the lip prints of the maximum experimental subjects matched with the individual. So it was concluded that lip prints behold the potential of fix the identity of a person. [ABSTRACT FROM AUTHOR]

Brief Background Examination of lip prints called cheiloscopy is first recognized by Fischer R.S. Lip prints do not change during the life of a person. Lip prints of parents, children and siblings have shown some similarities. It has been suggested that variation in lip print patterns among males and females could help in gender determination. Aim To assess the use of lip prints for gender determination among dental professional students in institution. Materials and Methods Fifty dental professionals were included in the study. The study included 25 males and 25 females. Lipstick was applied on upper and lower lip. An impression was taken with a strip of transparent cellophane tape and sticked to a white bond paper for evaluation of lip prints. Evaluation was done using Suzuki.T and Tsuchihashi Y.T criteria. Results Most of the subjects were in the age group of 16-20 years. The distribution and number of lip prints were more in females when compared to males. Type II lip patterns were more common followed by type III. Summary and Conclusions Cheiloscopy could be a supplemental tool along with other methods for gender determination. [ABSTRACT FROM AUTHOR]

The objective of the study was to specify the method with the highest probability of correct sex identification based on lip furrow pattern. Three methods were verified: Vahanwala's method, identification based on the mid-section of lower lip print and our own method. The examined group included 242 persons aged 15- 30 years, 68.6% females and 31.4% males. Cheilograms were taken with the method proposed by Vanahwala, modified in such a way that the prints of lower and upper lips were taken separately. The lip furrow patterns were classified according to Suzuki and Tsuchihashi, modified to include horizontal furrows which were considered by Renaud. In all the quadrants patterns II, III and VI prevailed among males and patterns I, I' and II among females. Females were more frequently diagnosed correctly than males. Our method in which all the lip print was analysed without division into quadrants was the most effective, while Vahanwala's method was the least so. [ABSTRACT FROM AUTHOR]

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]

On the red part of the human lips there is a system of grooves which creates a characteristic pattern that is unique for every person. Based on its uniqueness, durability, constancy and rehabilitation capabilities, lip prints are recommended as an appropriate method in the process of personal identification. We focused on determining the most frequently occurring pattern and on intersexual differences in lip prints in the population studied. We obtained the lip prints from 100 individuals (50 men and 50 women) at the aged of 18-40. We took the prints on the paper with a lipstick and an adhesive tape and evaluated them according to the Suzuki and Tsuchihashi classification. The most common pattern in the entire sample was type II (branched grooves), which also dominated by men and for women it was type I (complete vertical). Overall, we recorded the lowest occurrence in type I' (incomplete vertical) and type V (indeterminate). By statistical analysis, we found the difference between men and women, which has shown mainly on the upper lip in the first and second quadrant. In the lower lip, we did not notice statistically significant deviations. [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.
