Introduction: Forensic dentistry has become integral to forensic medicine over the past 100 years. Palatal rugae are the transverse ridges present on the anterior two thirds of the palate on both the sides of the median palatal raphe. Clinically they are seen as irregular and asymmetrical elevations on the mucosa in the midsagittal plane. These transverse palatine folds are well protected by its surrounding structures like the lips,cheek,buccal pad of fat, tongue and teeth in incident of fire and high end trauma .
Aim: The aim of our study was to identify the distribution of specific rugal patterns pertaining to any gender, to assess these parameters during forensic examination.
Methodology: .A total number of 100 patients were taken for the study out of which 50 were males and 50 were females and they were randomly selected from the archives. All subjects were between the age group of 15-24 years. The method of rugae recording used in this study was based on the classification given by Kapali et al.and includes shape and unification of rugae The shapes of individual rugae were classified as: Straight, Curved, Wavy ,Circular, Diverging and Converging.
Result: The study showed that the circular rugae pattern and wavy rugae pattern were higher in males than in females, curve and convergent rugae patterns were higher in females than in males and straight and divergent rugae patterns were equally distributed among males and females.

Conclusion: Our study showed a difference in the prevalence of the rugae pattern between males and females.
