The aim of this study was to evaluate the effects of malocclusions on facial attractiveness and to determine if it was correlated with the divine proportion.
Standard frontal facial photos were taken from 335 subjects in natural head position. Facial attractiveness of the subjects was evaluated by 10 dental students using a 10-point visual analog scale (VAS). All of the evaluations were arranged in order, and 30 attractive subjects with the highest score and 30 nonattractive subjects having the lowest score were chosen. On the frontal photos of these subjects, 13 landmarks were determined and 12 ratios were measured. Two way ANOVA was used to determine the effects of malocclusions on facial attractiveness, Student's t test was used to compare the facial proportions of the attractive and nonattractive subjects, and one sample t test was used to define the relationships between the divine proportion and facial ratios.
No statistically significant difference was found between malocclusion groups in terms of facial attractiveness. Of the 12 facial ratios, significant differences were found between attractive and nonattractive subjects regarding trichion-menton/nasion-menton, subnasale-menton/stomion-menton, nasion-subnasale/stomion-menton, nasion-subnasale/nasal width, and trichion-menton/right-left frontotemporale ratios. All of the ratios except nasion-subnasale/stomion-menton in the attractive group and subnasale-menton/stomion-menton and nasion-menton/nasion-trichion in the nonattractive group were found to be different from the divine proportion.
Sagittal skeletal malocclusions evaluated by ANB angle are not effective on facial attractiveness. Facial ratios used in this study have little effect on attractiveness, and are different from the divine proportion.
本研究旨在评估错牙合畸形对面部美观的影响，并确定其是否与黄金比例相关。
在自然头位下，为335名受试者拍摄标准正面面部照片。10名牙科学生使用10分视觉模拟量表（VAS）对受试者的面部美观进行评估。所有评估结果按顺序排列，选取得分最高的30名有吸引力的受试者和得分最低的30名无吸引力的受试者。在这些受试者的正面照片上，确定13个标志点并测量12个比例。采用双向方差分析确定错牙合畸形对面部美观的影响，采用学生t检验比较有吸引力和无吸引力受试者的面部比例，采用单样本t检验确定黄金比例与面部比例之间的关系。
在面部美观方面，错牙合畸形组之间未发现统计学上的显著差异。在12个面部比例中，有吸引力和无吸引力的受试者在发际点-颏下点/鼻根点-颏下点、鼻下点-颏下点/口裂点-颏下点、鼻根点-鼻下点/口裂点-颏下点、鼻根点-鼻下点/鼻宽以及发际点-颏下点/左右额颞点比例方面存在显著差异。发现有吸引力组中除鼻根点-鼻下点/口裂点-颏下点外，以及无吸引力组中鼻下点-颏下点/口裂点-颏下点和鼻根点-颏下点/鼻根点-发际点外的所有比例均与黄金比例不同。
通过ANB角评估的矢状骨面错牙合畸形对面部美观无显著影响。本研究中使用的面部比例对美观影响不大，且与黄金比例不同。
