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]

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]

Introduction: People possess distinctive individual characteristics that help in the identification and elimination of evidence during a crime scene reconstruction. This is a study that focuses on the reviews regarding particular aspects of odontological and facial recognition systems influenced by the integrity of forensic science and related studies. Forensic Odontology is the permissible application of odontological studies which include studies about teeth, gums, palatals, and lips. It is a branch of forensic science that deals with the standard collection and examination of dental marks and the appropriate assessment and demonstration of this evidence as a form of an expert witness in court. Under odontology, there are variance sequences of sub-topics that have been discussed so far including Cheiloscopy, Rugoscopy, and Dentistry. Moreover, this paper also discusses molecular biology and facial forensics which are evenly contributed to odontology. The essential uses of forensic odontology in the determination of human remains are grounded upon the exceptional features that prevail in the teeth of different individuals. This plays a vital role in the documentation of human remains in manifestations such as tidal waves, earthquakes, landslides, explosions, etc. Materials and Methods: We surveyed to understand the awareness among the public regarding crimes and forensics. The response was created from the google sheet circulated and it showed that there are still few gaps between the people and the field of crime investigation using these varied methods.

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]

Introduction: Cheiloscopy is the identification of humans based on lips traces used as a forensic investigation technique. Lip prints can be used as a reliable forensic tool, considering the consistency of lip prints over time and the accurate correlation of indirect prints to direct prints. Aims & Objective: The aim of this survey is to identify the awareness and knowledge of cheiloscopy among dental students. Materials and Methods: The cross sectional survey was done among 100 dental students in Chennai city after obtaining their informed consent. The survey instrument was a self designed questionnaire with 13 questions eliciting information about demographics of the participants and knowledge and awareness regarding Cheiloscopy. The questions were sent through a link which was passed around online through survey planet. The responses were collected, tabulated and analysed. Observation & Results: 94% of the students were aware of cheiloscopy. 75% of the students were not aware of the Suzuki and Tsuchihashi classification of lip prints. 84% of the population were aware of the obligations of cheiloscopy. 63% were aware that lip prints were subjective to change. 74% were aware of latent lip prints. Conclusion: This study concluded the awareness and knowledge about cheiloscopy was adequate among the dental students. However more rigorous continuing education programs can greatly enhance the knowledge about the forensic applications of cheiloscopy. [ABSTRACT FROM AUTHOR]

Background: Lip prints are the normal lines and fissures in the form of wrinkles and grooves present in the zone of transition of human lip, between the inner labial mucosa and outer skin. Yasuo Tsuchihashi presented a standardized classification of his own, for different types of lip print. He has classified lip prints into five types, which forms the basis of categorizing lip prints. 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. Aim: Present study was undertaken to provide deeper inside view of use of cheiloscopy in personal identification, focusing on sex variability of lip print patterns. This study was conducted to identify the pattern of lip prints and whether any sexual difference exists in lip prints in north India. Materials And Methods: Among the medical students studying in SGRR medical college, Dehradun who were native of north India were selected for the study. The cross-sectional study was conducted among 119 (65 males and 54 females) subjects of age 20-28 years, residing in different areas of north India. Frequency distribution and Chi-square test were used for data analysis by SPSS software. Applying the Chi-Square test, statistically significant differences (p < 0.001) were observed between male and female lip print patterns in middle 10 mm of the lower lip. Results: The most common lip print pattern in entire population was Type I (38%). Significant difference was found in the distribution of lip print patterns among males and females in the entire population, group I and group II, respectively (P < 0.001). Conclusion: This study shows that there is significant relationship in the pattern of lip print with sex which can serve as an important tool in forensic for personal identification and criminal investigation, thus, narrowing down the scope of investigation to almost half.
