笑弧在面部宽窄不同的个体中对微笑美学的影响

目的:研究面部宽窄不同女性的笑弧对微笑美学的影响。方法:选取女性正位微笑像1张,应用Adobe Photoshop CS5软件对笑弧和面部宽窄进行修改,由正畸医生和非专业人士对照片的微笑魅力值进行评判。结果:笑弧和面部宽窄程度在魅力微笑的判别中无交互作用(P0.05)。两组对理想的笑弧、略窄的面型和适宜的面型的魅力微笑判别分值较高(P0.05)。非专业人群中,在三种笑弧中,除了很窄的面型,魅力微笑的分值均随着面型的增宽降低(P0.05)。专业人群中,对于平坦的笑弧,除了很宽的面型,魅力微笑的分值随着面型的增宽而增加(P0.05);对于理想的笑弧,魅力微笑的分值随着面型的过宽或过窄而降低,但仍高于其他两种笑弧(P0.05);对于弯曲的笑弧,除了很窄的面型,魅力微笑的分值随着面型的增宽而降低(P0.05)。结论:笑弧和面部宽窄对魅力微笑的判别具有一定影响。不同人群对笑弧及面部宽窄与微笑美学的认识也存在差异,在正畸治疗中应根据患者面部宽窄合理的选择治疗方案。

Influence of Smile Arc on Smiling Aesthetics in Female Individuals with Different Face Widths

Objective:To explore the influence of smile arc on smiling aesthetics in female individuals with different face widths.Methods:One frontal smiling photograph from a female was modified for smile arcs and face widths with Adobe Photoshop CS5. The attractiveness of the images was evaluated by the orthodontists and the laypersons.Results:There was no interactive effect on the smile attractiveness between the smiling arcs and the face width (P>0.05). The higher scores of the smiling attractiveness were the ideal arc, narrower face & ideal face (P<0.05). For the laypersons, the three kinds of smiling arcs, except for the narrowest face, degree of attractiveness decreased as the face became wider (P<0.05). For the professionals, regarding the flatten arc, except for the widest face, degree of attractiveness increased with the width of face (P<0.05). For the ideal arc, degree of attractiveness decreased when the face was too wide or narrow, but it was still higher than the other two arcs (P<0.05). For the vaulted arc, except for the narrowest face, degree of attractiveness decreased as the face became wider (P<0.05).Conclusion:Smiling arc and face width can influence the evaluation of smiling attractiveness. Differences exist in perception of the influence of smiling arc and the face width on smiling attractiveness between the professionals and the laypersons. Therefore, the face width of patient should be considered during the orthodontic treatment for smiling attractiveness.
