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]

Aims and Objectives: Cheiloscopy is a technique of forensic odontology or forensic science which deals with examination of lip traces and furrows. This work aimed to study in detail the lip prints of individuals (males and females) in North Maharashtra (Dhule), to determine the most common pattern and to evaluate the differences in lip prints between males and females. Subjects and Methods: Lip prints of 496 individuals (326 males and 170 females) were obtained. The lip prints were analyzed using Adobe® Photoshop® software and classified according to the classification given by El Domiaty et al. The Z-test (SPSS software version 10.0) was used to test the significant difference between males and females for different types of lip patterns. Results: Our study was able to establish the uniqueness of lip prints. C pattern was found to be most predominant, which is different from studies done in other areas. This shows that geographic variation does exist in lip prints with respect to the most common pattern. On evaluation of patterns among males and females, it was found that there were differences in upper lip patterns among males (type-H) and females (type-C), whereas they were same in lower lip. Therefore, upper lip patterns can be considered more definitive in sex prediction. Furthermore, the lateral segments showed more sexual dimorphism than the medial segments. Conclusions: This study established the uniqueness of lip prints. According to this finding, we would suggest the creation of database of a given area or neighborhood, which would act as a guideline or comparative reference in cases which require forensic assistance.

Background: The study of lip-print pattern (cheiloscopy) is a scientific method for personal identification and plays a major role in forensic and criminal investigations. Objective: To compare the lip print patterns in Kerala and Maharashtra population and correlate between ABO blood groups. Materials and Methods: 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. Results: 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 0+ blood groups had type IV predominance. The lip print patterns do not show any correlation in ABO blood groups. Conclusion: Lip prints are unique to each individual and are different even in two persons. Lip print patterns were different in the two sub populations studied, and they showed no correlation in ABO blood groups. [ABSTRACT FROM AUTHOR]
