Abstract

Aim and objective: 1. To study the horizontal lip position in Dentally and Dentoskeletally normal subjects of Shimla adult population using different soft tissue analysis. 2. To study the sexual dimorphism in horizontal lip position of Shimla adult population. 3. To study the differences of horizontal lip position among Dentally and Dentoskeletally normal subjects of Shimla adult population. 4. To compare the horizontal lip position of Dentoskeletally normal subjects of Shimla adult population with established norms. 5. To assess the most consistent esthetic reference line.
Materials and Methods: Pre-treatment lateral cephalograms of 100 subjects aged between 18-25 years were taken, who visited the Department of Orthodontics and Dentofacial Orthopaedics Shimla, Himachal Pradesh for their orthodontic consultation for the study.
Results: In Shimla adult population retrusive upper lip in relation to Steiner’s S1 line, Ricketts’ E line and retrusive lower lip in relation to Steiner’s S1 line, Ricketts’ E line, Sushner’s S2 line was found. The norms for upper and lower lip position in relation to Burstone’s B line in Shimla adult population coincide with the established Burstone’s norms. Holdaway’s established norms for lower lip can also be applied to Shimla adult population.
Conclusion: Shimla adult population has different cephalometric norms for horizontal lip position in relation to Steiner’s and Ricketts’ line whereas same established norms of Burstone and Holdaway can be applied to Shimla adult population.
