Popis: Background: Forensic odontology plays important role in identification of human remains in mass disasters such as air crash, tsunami, and accidents. Palatal rugae act as an ideal requisite for human identification as they are present in all victims and are resistant to changes such as aging and trauma. The study aimed to analyze differences in shape and number of palatal rugae in population from Andhra Pradesh and Telangana states. Methods: This study was conducted in SIBAR institute of Dental Sciences, Guntur, India in 2012 on 200 subjects, gender matched and equally divided as 100 from Andhra Pradesh and 100 from Telangana states. Rugae were studied using Kapali.S classification. Association between rugae shape and gender variation between the two populations were tested by chi-square analysis and student t-test. Results: Average number of rugae was more (11.84±3.03) in subjects of Andhra Pradesh, compared to Telangana (9.50 ±1.65) population. Males of Andhra Pradesh showed significantly higher mean number of total rugae than in Telangana males. Distribution of total number of different rugae shapes in males and females of both the populations showed significant variation in wavy and circular rugae patterns. Wavy, curved and straight rugae were significantly higher in males and females of Andhra Pradesh compared to Telangana population. Telangana population showed significant increase in circular rugae. Conclusion: Our study revealed statistically significant variation in shape and total number of rugae between observed populations of Andhra Pradesh and Telangana states.
