Perioral soft tissue evaluation in various skeletal patterns: A lateral cephalometric study

Introduction-The importance of the facial aesthetics to the practice of orthodontics had its origin since beginning of the specialty. This study aims to assess the perioral soft tissue in individual having ANB angle 0-2°,3-5°, and more than 5° and Intergroup and Intragroup comparison of perioral soft tissue between the three groups. Material and Method-Lateral cephalogram of 103 patients were randomly selected between the age 18-29 years which were divided into three groups Group I having ANB angle (0-2°), Group II having ANB angle (3-5°) and Group III having ANB angle >5° respectively. All the respective parameters comprising of perioral soft tissue were measured. Result: No statistical difference in the soft tissue changes were found among Group I and Group II while differences between Group I and Group III were found to be statistically significant only for Lower Lip Thickness, and difference between Group II and Group III were found to be statistically significant only for Lower Lip Thickness. Conclusion: The present study found important correlations when analyzing associations between the perioral soft tissue parameters in various skeletal patterns.
