摘要

Introduction: The profile view of the soft tissue can be used to determine the treatments to maintain or enhance thebeauty. Accordingly, evaluation of the soft tissue in this view in patients u8ndergoing orthodontic treatment ororthogenetic surgery may perform very important role in the diagnosis and ideal treatment plan. The purpose of thisstudy is to evaluate and compare the thickness of the chin soft tissue in patients with the age 18-32 years old withdifferent vertical skeletal patterns using lateral cephalometric images.Materials and methods: This is a cross-sectional study using lateral cephalometric radiographs of 67 women and 43men, 18-32 years old (average 23.52 ± 4.1 years) with normal anteroposterior skeletal relationship in three groups ofhyperdivergent (n=36, MP angle ≥ 28°)?normodivergent (n=34, 17° ≤ MP angle ≤ 28°) and hypodivergent (n=40, MPangle ≤ 17°). The soft tissue thickness was measured at three points of Gnation, Menton and Pogonion and the datawas analyzed using analysis of variance (ANOVA), bonferoni post-hoc and Pearson correlation coefficients in avariety of face form.Results: The correlations in distance of Pog - Pog' (P = 0.744), Gn - Gn' (P = 0.358) and Men- Men' (P = 0.680) interms of increasing age number were not statistically significant. However, based on the results of the averagethickness of the chin soft tissue in both groups of men and women in all three points the significant difference wasobserved (p < 0.0001).Conclusion: Based on the outcome of this study for the age group of 18 to 32 years there is no relationship betweenage and changes in the chin soft tissue. The chin soft tissue thickness at three points has been more in men thanwomen and the most obvious difference in the thickness of the chin soft tissue of men and women were observed innormodivergent face. The thickness of the chin soft tissue at all three points of measurements was more in people withhypodivergent face compared to people with hyperdivergent face.
