This study ascertained the influence of orthodontic appliances on subjective ratings for social competence (SC), intellectual ability (IA), psychological adjustment (PA), and attractiveness in young adult orthodontic patients. A cross-sectional analytical questionnaire study was conducted with 130 undergraduates from the UK. Each participant was asked to look at a single, randomly assigned colour photograph of a young adult female and then asked to make judgements concerning her personal characteristics. Five modified photographs of the same young adult female were used: (1) no appliance, (2) stainless steel fixed orthodontic appliance, (3) ceramic fixed orthodontic appliance, (4) gold fixed orthodontic appliance, and (5) clear colourless aligner. Likert scales with higher scores indicating more positive ratings were used. The results were analysed using chi-square test, one-way univariate analysis of variance, and post hoc Tukey-B and Kruskal-Wallis tests. The results showed that greater perceived IA was associated with the appearance of no appliance (mean values: 7.56) rather than steel (6.67) or ceramic appliances (6.65) but similar to the gold (7.35) and aligner (7.08) appliances. No significant differences between the different orthodontic appliance appearances were found for SC and PA. A trend existed where the no appliance image (resembling a lingual appliance) or clear aligner was considered more attractive than the visible buccal fixed appliances. In the absence of other information, the judgements an individual young adult makes concerning the personal characteristics of a young adult are influenced by dental appearance and orthodontic appliance design. This may influence orthodontic appliance choice.
本研究旨在确定正畸矫治器对青少年正畸患者社会能力（SC）、智力能力（IA）、心理调整（PA）和吸引力的主观评价的影响。采用横断面分析问卷调查法，对来自英国的 130 名本科生进行研究。每个参与者都被要求观看一张年轻成年女性的单张、随机分配的彩色照片，然后被要求对她的个人特征做出判断。使用了同一位年轻成年女性的五张经过修改的照片：（1）无矫治器，（2）不锈钢固定矫治器，（3）陶瓷固定矫治器，（4）金固定矫治器，和（5）透明无色矫治器。使用了更高分数表示更积极评价的李克特量表。使用卡方检验、单变量方差分析和事后 Tukey-B 和 Kruskal-Wallis 检验对结果进行分析。结果表明，与钢（6.67）或陶瓷矫治器（6.65）相比，更多人认为无矫治器（平均值：7.56）的 IA 更高，但与金（7.35）和透明矫治器（7.08）的 IA 相似。在 SC 和 PA 方面，不同正畸矫治器外观之间没有发现显著差异。存在一种趋势，即无矫治器（类似于舌侧矫治器）或透明矫治器比可见颊侧固定矫治器更具吸引力。在没有其他信息的情况下，个体对年轻成年个体的个人特征的判断受到牙齿外观和正畸矫治器设计的影响。这可能会影响正畸矫治器的选择。
