Abstract: Objective: The research was conducted to determine the correlation of hard and soft tissue parameter in skeletal class II malocclusion. The outcome of the study will help in determining if the routine consideration of ANB angle with the lack of defined thresholds for convexity of soft tissue profile justified for choosing the treatment modality. Material and methods: Lateral cephalograms of 141 skeletal class II subjects (ANB>4°) were obtained. Angular parameters including soft tissue angle of facial convexity (SA-FC) and angle ANB were determined. Gender dimorphism of the variables was assessed by Mann Whitney U test. Correlation between SA-FC and angle ANB were determined utilizing Spearmans correlation coefficient. Results: The angle SA-FC and ANB depicted moderately positive correlation (r = 0.662, p Key words: Cephalometry, Malocclusion, Diagnosis, soft tissue, correlation.
