Evaluation and co-relation of lower anterior facial height and soft-tissue characteristics in between genders in North Indian population: A cephalometric study

Objective: The purpose of this study was to establish lateral cephalometric soft-tissue norms for the adolescent North Indian population. Materials and Methods: Three hundred and thirty-three Indian adults of age group 18–30 years were selected. The standardized lateral cephalometric radiograph was taken for each subject. Fourteen linear measurements were recorded on each lateral cephalometric radiograph. Statistical analysis was done using the Statistical Package for the Social Sciences (SPSS 26). Group differences were analyzed with independent t-test. Results: The results of the study showed significant gender dimorphism, with men having thicker soft tissue structures, larger vertical dimensions, than women. Conclusion: Significant gender dimorphism was evident within the local population suggesting the necessity for a separate set of norms for males and females. Distinct ethnic differences were found between Caucasians and the North Indian population that were statistically significant, highlighting the importance of defining separate set of norms for ethnic groups.
