Abstract

Aim: The purpose of the study was to establish soft tissue cephalometric standard norms of Legan – Burstone (COGS) Analysis for ethnic Himachalli population.

Materials and Methods: The Lateral cephalograms of sample size of one hundred Himachalli ethnic subjects that met the inclusion criteria in Natural Head Position (NHP) were taken and subjected to Digital soft tissue facial analysis using Nemoceph. Establishment of soft tissue norms for Himachal ethnicity in relation to various cephalometric parameters was done using Shapiro-Wilk test and the level of significance for the present study was fixed at p-value of less than 0.05.

Results: The facial convexity angle, Neck to Lower third angle and lower lip protrusion was found statistically significant (p<.01).

Conclusion: The present study suggested that a slightly convex facial profile, protrusive lower lip and obtuse Neck to Lower third angle is acceptable in the Himachalli population with slightly retrognathic mandible and slightly prognathic maxilla.
