- Abstract
Background: Tools for establishing identity is invaluable part of forensic sciences form the beginning of the profession. Odontology is one of such branches which in early days started in its crude form with identification of different species and races within the species, currently is an individual subject with specialist societies, journals and courses. Palatal rugae, was identified to be a potential tool for establishing identity few centuries back itself but is not validated even today to be part of standard protocols. This is a pilot study comparing two racial groups i.e., Indian and Malaysian with established parameters for palate rugae aiming at testing the feasibility of the parameters to be used in identification of individuals and racial groups and also to provide preliminary data to make way to larger studies. Aims and Objectives: The aim of this pilot study is to explore the feasibility of palate prints as tool for identification by, studying palate print in Indian and Malaysians and Comparison of plate Rugosity between Indians and Malaysians students for identification. Methodology: Study population was male Indian and Malaysian Medical and Dental students, age between 18-25 years studying at Mangalore, India. Sample size 80 (40 in each group); were selected for studying of Palatal Rugae. The palate impressions were collected using maxillary alginate cast. The parameters assessed were: Total number of rugae, number of primary rugae (length- 5 to 10 mm), secondary rugae (3-5mm), fragmentary rugae (less than 3 mm). Comparison for two populations was done using non-parametric MannWhitney Test. Results: There were no statistically significant differences among the Indians and Malaysians in total number and number secondary rugae in both sides more in Indians than Malaysians. There was statistically significant difference in number of the primary rugae and the fragmentary rugae, which in both sides were more in Indians than Malaysians. Conclusion: In conclusion, palatal rugae pattern are unique to an individual and their use in forensic identification has been advocated and applied. Our study demonstrated significant difference in the number of primary rugae on each side. It was more in Indians than Malaysians. This study demonstrated the uniqueness of rugae pattern in different individuals. Thus, it appears to be an effective & reliable source of identification.
