dc.description.abstractBackground: Palatal rugae are unique for an individual and remain unchanged during individual's lifetime. Application of palatal rugae analysis as a method in gender identification needs to be confirmed with more scientific studies. The objectives of the present study were to assess the distribution of the palatal rugae patterns in Kerala population and compare the distribution of these parameters between males and females. Materials & Methods: A retrospective cross-sectional study was conducted by evaluating the casts of 100 dentate individuals, between the age of 18 and 30 years. The rugae were divided into two halves and patterns were then assessed as per Thomas and Kotze classification. Independent sample t-test was used to assess the significant difference of each type of palatal rugae between males and females. Results: Wavy rugae (mean – 5.6 ± 0.7) was predominant among males whereas curved (mean – 4.6 ± 0.6) and circular rugae (mean – 0.9 ± 0.3) were more in females, and were found to be statistically significant (p<0.05). The mean number of secondary rugae in females (1.5 ± 0.5) was greater than that of males (1.3 ± 0.4), and was found to be statistically significant (p<0.05). The diverging type was commonly found in females compared to males. Conclusion: Our findings showed statistically significant differences in the shapes and patterns of rugae between males and females among Kerala population. Thus, morphological analysis of palatal rugae can be considered as an additional aid in forensic odontology for gender differentiation.en_US
