Abstract

Abstract: Objective To explore the difference of soft tissue profile evaluation in malocclusion patients through NRS score on silhouette of different kinds of malocclusion. Methods Sixty patients with malocclusion were selected from Orthodontics Department of Changshu Yuhui Dental Hospital and Affiliated Stomatology Hospital of Soochow University in 2019, including 20 cases of skeletal Class Ⅰ, Ⅱ and Ⅲ respectively. A total of 30 evaluators were selected with 10 patients of skeletal Class Ⅰ, Ⅱ and Ⅲ respectively. The 60 orthodontic patients were randomly numbered, and the right 90° silhouettes on PowerPoint were rated by evaluators according to NRS scoring criteria. The scores of different groups were compared between groups and within groups. Results Comparing the silhouette scores by skeletal Class Ⅰ, Ⅱ and Ⅲ malocclusion patients, the score of skeletal Class Ⅰ was the highest. Rated by skeletal Class Ⅲ patients, the score of Class Ⅱ patients was higher than that of Class Ⅲ. From high to low, scores rated by male patients were: skeletal Class Ⅰ, Ⅱ and Ⅲ. Scores rated by female patients for Class Ⅰ was significantly higher than those for Class Ⅱ and Ⅲ, and there was no statistical difference in the scores of Class Ⅱ and Ⅲ. Male patients gave higher scores than female. Conclusion Patients with different malocclusions prefer skeletal Class Ⅰ, and skeletal Class Ⅲ patients and male patients think that the lateral profile of skeletal Class Ⅱ is more beautiful than Class Ⅲ. The aesthetic requirements of female patients are higher than those of male.
