Context: Many studies on rugae pattern have been done on various samples of population, but no study has so far been done to assess the rugae pattern of population of western Uttar radesh, especially Meerut. Aims: This study was aimed to assess the rugae pattern in males and females of a sample of population of Meerut, which may be an additional method of determining gender when dealing with any crime or with mutilated bodies that have undergone damage beyond recognition. Settings and Design: A total of 100 Class I dentulous subjects, 50 male and 50 female patients reporting to the outpatient department of Kalka Dental College, Meerut, Uttar Pradesh were randomly selected with an age range between 20-30 years. Exclusion criteria were subjects >14 years of age, congenital malformations, previous orthognathic surgery, allergy to impression material, bony and soft tissue protuberances, active lesions, deformity or scars and trauma of the palate. Prior approval from the Institutional Ethical Committee was taken. Subjects and Methods: Alginate impressions of palate of selected patients were poured in dental stone and rugae pattern was identified and analyzed by a single rater employing Thomas and Kotze's (1983) method. Statistical analysis used: Two-sample t-test and Chi-Square tests were used for comparison of means and relationship between the attributes. A significance level of 5% was considered as critical value. Results: No significant difference was noted in total number or length of rugae between the genders. However, statistically significant difference in the circular type in males and converge type in females was observed. Conclusion: Rugae pattern can be used as a method of differentiation between males and females to corroborate the findings of other methods such as anthropometric evaluation of the cranium and dental characteristics.
