Aims and Objectives: To evaluate and compare the soft-tissue characteristics associated with Angle's Class-I normal occlusion and Angle's Class-II division-2 malocclusion in North Indian adult population. Materials and Methods: Lateral cephalograms of 70 orthodontically untreated adult subjects, 40 were having normal occlusion (Group-A) with good facial profile (20 males - mean age 22.89 years and 20 females - mean age 21.27 years) and 30 subjects with Angle's Class-II division-2 malocclusion (Group-B) (15 males - mean age 22.50 years and 15 females - mean age 20.25 years) were analyzed. All the cephalograms were taken in natural head position, traced manually and 16 linear and 6 angular soft tissue parameters were measured which were derived from the Steiner, Ricketts, Burstone and Holdaway soft-tissue analyses. All the values were compared using Student's t-test with a level of significance at P < 0·05. Results: Group-B males had significantly higher mean values for lip-line, soft-tissue thickness at labialis inferior (P < 0.05), and total facial contour angle (P < 0.01), whereas, Group-A males had significantly higher values for lower lip-chin length (P < 0.001), lower face height, soft-tissue chin-thickness (P < 0.01) and nasomental angle (P < 0.05). Group-B females had significantly higher values for lip-line (P < 0.05), soft-tissue thickness at labialis superior (P < 0.01), at labialis inferior and mandibular sulcus contour angle (P < 0.05) whereas, Group-A females had significantly higher values for upper lip length, lower lip-chin length (P < 0.01), lower face height (P < 0.001), nose length and lower lip to Sn-Pg' (P < 0.05). There was an apparent sexual dimorphism was found in soft tissue pattern of both the groups. Conclusions: Angle's Class-II division-2 malocclusion subjects have decreased lower lip-chin length and lower face height, while they have an increase lip-line, soft-tissue thickness at labrale superius, soft-tissue thickness at labrale inferius, total facial contour angle and mandibular sulcus contour angle.
