Abstract

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 (?2statistic = 37.56, p value <0.05) and between finger prints and ABO-Rh factors (?2 statistic = 30.6, p value < 0.05). No association was found between palatal rugae with ABO-Rhesus blood groups (?2 statistic = 17.71, p value >0.05).

Highlights

Proper identification enacts an important step in forensic odontology that is required for ethical, humanitarian and criminal investigations as well as in archaeology and paleo demographic support research studies. [1,2] Scientific methods using DNA are considered to be expensive and time-consuming approach, initiating the need for using less expensive and faster methods of identification
The methods using lip print, finger print and palatal rugae are considered to be unique to individuals and have gained tremendous importance in forensic odontology these days
There was no significant association between lip prints and ABO blood group (p> 0.05) (χ2 statistic = 18.84, p = 0.093)

Summary

Introduction

Proper identification enacts an important step in forensic odontology that is required for ethical, humanitarian and criminal investigations as well as in archaeology and paleo demographic support research studies. [1,2] Scientific methods using DNA are considered to be expensive and time-consuming approach, initiating the need for using less expensive and faster methods of identification. The methods using lip print, finger print and palatal rugae are considered to be unique to individuals and have gained tremendous importance in forensic odontology these days. Due to its internal location in the head, these patterns usually, do not undergo any changes in one’s life, the only exception being its length. Another biological record that remains unchanged during the life time of a person is blood grouping. Considering all these points, we decided to conduct a study to correlate and compare Cheiloscopy, Dactyloscopy and Palatoscopy
