Abstract

The aim of this study was to evaluate the soft tissue profile changes during growth in a group of Isfahanian children, using the Holdaway analysis and determining the sexual dimorphism in studied group. In this descriptive-analysis study, 143 lateral cephalograms from a group of 6-15 years old Isfahanian children were evaluated and the changes were determined by Holdaway soft tissue analysis. The samples had cl l occlusion, no crowding or rotation of teeth, normal growth and development, normal skeletal profile and without earlier orthodontic treatment. All radiographs were analyzed by the Holdaway analysis. Data was analyzed using the t-test, Kolmograv Smirnov, ANOVA and Duncan tests. Indices that increased significantly with growth were: soft tissue facial angle, nose prominence, basic upper lip thickness, soft tissue chin thickness (p<0.05). Superior sulcus depth had no significant change with age (p = 0.5) and all other indices decreased significantly with age (p<0.05). Some indices were significantly different between two genders: nose prominence, basic upper lip thickness, soft tissue chin thickness, H-angle, sub-nasal to H-line (p<0.05). When comparing the 14-15 years age group with the Holdaway norms most indices were in the normal range except: skeletal profile convexity, H-angle, basic upper lip thickness and soft tissue chin thickness which were significantly higher than Holdaway norms (p<0.05). The results suggest that facial convexity decrease with age. Nose prominence and basic upper lip thickness increases in both sexes especially in males. Isfahanian 14-15 years old children had more convex profiles and thicker base upper lips compared to Holdaway norms. © Medwell Journals, 2013.
