Abstract

Abstract: PURPOSE: To explore the factors influencing aesthetic perception changes among non-orthodontic professionals with higher education in Shanghai regarding the maxillofacial appearance of women before and after orthodontic treatment with extractions. METHODS: A total of 18 non-orthodontic professionals (9 men and 9 women) who had received or were receiving higher education in Shanghai were recruited. Using Q-sort technique, the study compared pre- and post-treatment facial soft tissue changes in 48 adult females who underwent orthodontic treatment with extractions. RESULTS: Non-orthodontic professionals with higher education in Shanghai showed significant sensitivity to changes in the lower third of the face, overall facial contour, mouth corners, and chin of women before and after orthodontic treatment (P<0.05). However, changes in the nasolabial fold and upper and lower lips, which were often the focus of orthodontic professionals,didn't show significant differences in aesthetic perception. Female reviewers were more sensitive than male reviewers to aesthetic changes in the chin and lower third of the face, but there was no significant difference in overall facial evaluation. Reviewers born in the 2000s and 1990s demonstrated higher aesthetic sensitivity, while those born in the 1970s and 1980s showed more stable aesthetic evaluations. CONCLUSIONS: Non-orthodontic professionals with higher education experience in Shanghai are more sensitive to the aesthetic changes in the lower 1/3 of the face, chin and other areas after orthodontic treatment with tooth extraction, and the perceived differences are affected by gender and age, which can provide a reference for the design of endpoint goal schemes in clinical orthodontic treatment.
