Forensic corner INTRODUCTION Forensic science is defined as the application of scientific methods and techniques to matters under investigation by a court of law. Forensic science in a broad sense deals with criminal investigations by the identification of the body, cause and manner of death. The identification of person plays an important role in the investigation of the unidentifed body in mass disaster or criminal suspects and also in recognizing missing persons. [1] Various parameters such as fingerprinting, DNA testing, blood examination, body fluids and hair are used for the purpose of identification. [2,3] Identification plays a vital role in any medico-legal inquiry. Identification is done to determine the individuality of a person. Identification means to confirm the identity of the person beyond any doubt. Partial identification 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.
A study of lip prints in relation to gender, family and blood group
International Journal of …, 2010
Background: In forensic identification, the mouth allows for a myriad of possibilities. The use of lip prints is not so popular but exists as a methodology in forensic science. Hence Dental surgeon has to actively play his role in personal identification and criminal investigation, as his evidence would be very much useful in law and justice. Objective: The objective of present study was to evaluate in depth the lip print patterns in relation to gender, its consistency for a period of time, to ascertain whether there is any hereditary pattern in lip prints among families with siblings and twins, and thereby, to investigate whether the lip prints are unique to any blood group in the population under investigation. Materials and Methods: This study was conducted on 100 students and 10 family with children and twins respectively. The lip-print of each subject was obtained on a microscopic glass slide without applying anything and developed with carbon powder dusting with ostrich brush. Blood group information was noted. Results: Our study showed, in boys, the Type I (complete vertical), in girls, Type II (branched) and among both, type II (branched) lip print pattern to be most prominent pattern. The present study showed a good consistency of the lip print pattern when observed for a period of six months consecutively. The study has not found any statistical correlation of lip print with family members or even any correlation between blood group and lip prints. Conclusion: Although lip print identification has been utilized in the court of law in isolated cases, more research needs to be conducted in this field, with regard to confirmation of its uniqueness. Hence chelioscopy has to be carried out in depth on larger sample size using newer scientific technologies.
A Study of Dactylography and Cheiloscopy Patterns and Their Relationship with ABO Blood Groups
2014
Background: Establishing a person’s identity is a very important process in civil and criminal cases. Dental, fingerprint and DNA comparisons are probably the most common techniques allowing fast and secure identification processes. However, in certain circumstances related to the scene of the crime or due to lack of experienced personnel, these techniques might be unavailable; so there is still an increasing need for reliable alternative methods of establishing identity. Aim: To study correlation between lip print pattern, finger print pattern and ABO blood group. Materials and Methods: The study group consisted of 141 males and 105 females who were aged between 20–40 years. Lip prints, finger prints and ABO and Rh blood groups of each individual were recorded. Lip prints were classified, based on Suzuki’s and Tsuchihashi’s classification and finger prints were classified, based on Michael’s and Kucken’s classification. The results were statistically analyzed by using Chi–square te...

The study of lip-print pattern (cheiloscopy) is a scientific method for personal identification and plays a major role in forensic and criminal investigations. To compare the lip print patterns in Kerala and Maharashtra population and correlate between ABO blood groups. Two hundred subjects, 100 from Maharashtra and 100 from Kerala were considered for the study. Lip prints were recorded, analyzed according to Tsuchihashi classification. The lip print patterns were compared in the two populations, correlated in ABO blood groups. The data obtained was statistically analyzed with SPSS software using chi-square test. In our study, predominant lip print pattern observed in Kerala population was type IV (53%) and Maharashtra population was type II (42%). The difference between the two population was statistically significant (p<0.001). Subjects with A+ and O- blood groups had type II lip print predominance. Subjects with B+, AB+ and O+ blood groups had type IV predominance. The lip pri...
LIP PRINTS AND BLOOD GROUPS, AMONG TWO SOUTH INDIAN POPULATION- AN IN-VIVO STUDY
Collection and classification of lip print, from the crime scene has an important role, in identification of the person in forensic dentistry. Studies have shown that, different racial and ethnic groups show differences in the predominant lip print pattern. Aim: To study the lip print pattern in relation to gender, geography and ABO blood group and Rh system Materials and Methods: A cross-sectional study was done by purposive sampling. The sample size was 100 [50 from Kerala and 50 from Karnataka], each group in turn comprise of 25 males and females. After applying lipstick evenly, lip print was obtained, by dabbing a strip of cellophane tape and classified, as per Tsuchihashi's system. The data was analyzed and expressed in proportions and chi-square test, for statistical significance was used. Results: Type IV (32%), followed by Type II (30%) were the commonest lip pattern observed. Type IV was commonly found, both in Kerala and Karnataka group followed by Type II and type I. This was statistically significant at p value of 0.5(X 2 =3.06 df:4 p=0.5. Males had Type IV (42%) has the commonest pattern and females had Type II (28%), however the differences was not significant statistically (. X 2 =16.8 at df:4 p=0.001). Type IV and Type II pattern is seen in almost all the blood group, except in AB-ve and B-ve individuals. Type I pattern found, in Rh-positive blood group only. Conclusion Difference in lip pattern was observed in relation to geography, but not with gender and ABO blood group.
Correlation of lip prints with gender, ABO blood groups and intercommissural distance
North American Journal of Medical Sciences, 2013
Background: In forensics, the mouth allows for a myriad of possibilities. Lip print on glass or cigarette butt found at crime scenes may link to a suspect. Hence, a dentist has to actively play his role in personal identification and criminal investigation. Aims: To investigate the uniqueness of the lip print patterns in relation to gender, ABO blood groups and intercommissural distance (ICD). Materials and Methods: The study was conducted on 208 randomly selected students. The lip print of each subject was obtained and pattern was analyzed according to Tsuchihashi classification. The blood group and ICD at rest position was recorded for each. Results: The study showed that Type II (branched) lip pattern to be most prominent. The B+ blood group was the most common in both genders and the ICD is higher in males. The lip print pattern does not show any correlation between ABO blood groups, gender, and ICD. Conclusions: The lip print pattern shows no correlation with gender, ABO blood groups, or ICD. Further studies with larger samples are required to obtain statistical significance of this correlation.
A Review of Lip Print as A Tool in Forensic Dentistry
Tikrit Journal for Dental Sciences
Background: Forensic dentistry requires interdisciplinary knowledge since the data obtained from the oral cavity can contribute to identify an individual or provide the information needed in a legal process. Identification is a major problem facing forensic practitioners, DNA and fingerprints are highly useful but sometimes are not easily collected from the crime scene. Lip print could be useful in this field the lip prints are unique and distinguishable for every individual like fingerprints. The external surface of lips has many elevations and depressions forming a characteristic pattern called lip prints, examination of which is known as Cheiloscopy. However, there are many well-known implanted methods of human identification. Historical Background: The biological phenomenon of systems of grooves on the red part of human lips was first noted by anthropologists, Fischer was the first to describe it in 1902. The use of lip prints in personal identification was first recommended in ...
Lip prints Role in forensic odontology
Identification plays a major role in any crime investigation. The pattern of wrinkles on the lips has individual characteristics like fingerprints. Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. In the past decades, lip‑print studies attracted the attention of many scientists as a new tool for human identification in both civil and criminal issues. The lip crease pattern is on the vermilion border of the lip, which is quite mobile and lip prints may vary in appearance according to the pressure, direction and method used in making the print. It concludes by enlightening the readers with the fact that the possibilities to use the red part of lips to identify a human being are wider than it is commonly thought.

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 u...
