Aims: The aims of present study are: 1. To assess Facial soft tissue thicknesses for males and females of different skeletal classes on Lateral cephalograms.2. To assess any possible correlation between Facial soft tissue thicknesses, gender and skeletal class es.3. To assess any possible correlation between Facial soft tissue thicknesses and Body Mass Index.
Materials & methods: Sample included patients reported to department of Orthodontics. Total sample of 200 patients including 100 males and 100 females was taken. Body mass index (BMI) of each individual was calculated and soft tissue thickness at different facial points was measured from lateral cephalograms.
Results and conclusion: Facial soft tissue thickness (FSTT) was significantly different among class I, II and III females for point Sn. Highly significant positive correlations between FSTT and BMI were obtained for points G, Lm, Po, Gn in males while in females, significant correlations were observed at points G, Na, Lm and Po.
