Abstract
Background: This analysis is a radiographic instrument that was developed directly from the philosophy expressed in Arnett and Bergman “Facial keys to orthodontic diagnosis and treatment planning, Parts I and II”. The novelty of this approach, as with the “Facial Keys” articles, is an emphasis on soft tissue facial measurement. This article describes comparison of various soft tissue traits between Himachali and Caucasian female population that contribute to an aesthetically pleasing face which should be considered during orthodontic treatment. The aim of the present study was to highlightthe differences in TVL projections norms between Himachali and Caucasian population. Materials and Methods: Lateral cephalograms of 50Himachali femalesof age group 18-25 years were taken in Department of Orthodontics, Himachal Institute of Dental Sciences, Paonta Sahib and tracing of soft tissue profile as well as related osseous and dental structures were made using Nemoceph software. Then Arnett’sTrue vertical projection norms were compared with Himachali traits. Results: The values of the projections to TVL are less in Himachali female population as compared to Caucasian population. Conclusion: The soft tissue is more pronounced in Caucasian females as compared to Himachali females when taken in reference to TVL line.
