Aims and objective: Study comprised of 80 individuals with 20 each in every group with age ranging between 20 to 55 years. Ten linear and angular parameters were measured on lateral cephalometric radiographs. Statistical analysis was carried out for each variable using student‘t’ test.
Result: The results showed that the SN-H line and H angle was found more in skeletal class II males and skeletal convexity was more in skeletal class II female on intergroup comparison.. In the present study Rajasthan population with skeletal class II were observed to have a significantly protruded mandible. When values of Southern Rajasthan population were compared with Hold away norms, skeletal class I in the study reveal that values obtained for SK convexity, ULT, and H angle were more than that of Holdaways norms. This suggests that Southern Rajasthan population have a more convex profile and also protruded mandible with thick upper lip. Conclusion: It has been concluded that Rajasthani population standards for Holdaways analysis was found to be statistically different from other ethnic groups. Considering such standards for the studied population would aid in better diagnosis and treatment planning.
