Norms for Jharkhand population using tweeds analysis

Objective: This study comprised of creating norms for Jharkhand population using tweeds analysis.Materials and Methods: The study sample consisted of Standardized lateral cephalograms obtained from 100 subjects (50 males and 50 females) belonging to Jharkhand population of 18-25 years comprising of normal occlusion and pleasing facial profile. Tweeds cephalometric analysis was performed and difference between male and female samples was recorded. Mean values were evaluated and compared to Caucasian population and norms were created for Jharkhand population.Results: Mean FMA value for females was found to be significantly higher than that of males (t48 = 2.97; p<0.01) and the mean value of IMPA for males was significantly higher than that of females (t48 = 2.45; p<0.01). However, no statistical difference was seen when compared to Caucasian population.Conclusion: Results showed no statistical difference between the Jharkhand population and the Caucasian population but difference were observed between the male and female population.
