The aims of the study were to comprehensively assess the perception of altered dentofacial aesthetics between dental students and laypersons and to identify the threshold where different variables such gender and clinical training impair dentofacial attractiveness.
Ten photographs were digitally manipulated involving three facial, two smile, four dental, and one gingival components. Fifty images were randomized and rated according to attractiveness by two groups dental students which subdivided into preclinical students and clinical students, and laypersons. The participants evaluated the original and manipulated images using a visual analog scale. The responses were then analyzed using Mann-Whitney U test.
The results showed threshold levels of noticeable differences between varying levels of discrepancy. The overall perception of aesthetics was high among dental clinical students with the highest perception toward facial profile and the lowest toward gingival margin height. Of the respondents, no differences were found in the perception between male and female participants. Dental students perceived aesthetic components more accurately than laypersons.
Dental students group had a better perception of dentofacial aesthetics than included laypersons. Unlike gender, clinical training has a substantial positive effect on the assessment of beauty. Dental students sub divided into dental preclinical students and dental clinical students (clinical training is a variable of all subgroups).
本研究的目的是全面评估牙科学生和非专业人士对牙颌面美学改变的认知,并确定不同变量(如性别和临床培训)损害牙颌面吸引力的阈值。
对十张照片进行数字处理,涉及三个面部、两个微笑、四个牙齿和一个牙龈部分。五十张图像被随机排列,并由两组牙科学生(分为临床前学生和临床学生)以及非专业人士根据吸引力进行评分。参与者使用视觉模拟量表对原始图像和处理后的图像进行评估。然后使用曼-惠特尼U检验分析结果。
结果显示了不同差异水平下明显差异的阈值水平。牙科临床学生对美学的总体认知较高,对面部轮廓的认知最高,对牙龈边缘高度的认知最低。在受访者中,男性和女性参与者的认知没有差异。牙科学生比非专业人士更准确地感知美学成分。
牙科学生组对牙颌面美学的认知比纳入的非专业人士更好。与性别不同,临床培训对美的评估有显著的积极影响。牙科学生分为牙科临床前学生和牙科临床学生(临床培训是所有亚组的一个变量)。
