AbstractSoft tissue analysis is integral for patients undergoing orthodontic treatment. Both hard and soft tissues must be considered for harmonious facial esthetics and optimal occlusion. As there has been the latest paradigm shift from hard tissue to soft tissue and how it is affected in treatment. Visualizing only the hard tissues alone, i.e., the teeth and jaws in terms of discrepancy posed a problem which could be easily tackled in a direct manner to achieve ideal values. But soft tissue drape compounded the problem. This is due to the variability in soft tissue thickness covering the teeth and bone. Hence, the aim of the present study was to evaluate and compare soft tissue thickness in skeletal class I and class III pattern Materials and methodology-This was a retrospective study based on a university-setting wherein the lateral cephalograms of the patients who had visited saveetha dental college and hospital were retrieved. The total sample consisted of 20 lateral cephalograms. Independent t-test was carried out to evaluate soft-tissue chin thickness difference between skeletal class I and class III. Chi-square test was done to evaluate gender association. The significance level for the p-value was set at 0.05. Independent T-test reported that there was a statistically significant soft-tissue chin thickness observed between skeletal class I and class III (p=0.02, p<0.05). Chi-square test indicated that there was a statistically significant association observed in gender (p=0.012, p<0.05) Within the limitations of this study, it was concluded that there was a significant soft-tissue chin thickness observed between skeletal class I and class III. There was a statistically significant association of soft tissue chin thickness at Pog in both males and females.
