SUMMARY BACKGROUND/OBJECTIVES: Social perceptions are influenced by dental appearance. The aim of this study was to determine whether social perceptions of a young adult are influenced by orthodontic retainer design and appearance.
Following ethical approval, a pilot-tested questionnaire study was conducted with 402 third-level students from the Republic of Ireland. Each participant was invited to look at one randomly allocated colour full-face smiling photograph of a young adult male or a young adult female wearing one of five maxillary retainers and asked to make judgements on a Likert scale concerning the subject's social competence (SC), psychological adjustment (PA), intellectual ability (IA), and attractiveness. Five computer-modified standardized photographs of each subject wearing each of the following retainers were used: Essix, conventional Hawley, acrylated Hawley, and Begg; an image with no retainer simulated a bonded retainer (BR) appearance. Statistical analyses were performed in SAS® (Version 9.2).
No significant differences were found between the retainers for SC (P = 0.6741) and PA (P = 0.7217). In the male subject only, greater perceived IA was found with the BR appearance compared to that of the conventional Hawley (P = 0.0018) or the acrylated Hawley (P = 0.0016). The BR appearance was perceived as more attractive than that of the Begg retainer (P = 0.0103).
In this study, participants were required to make arbitrary judgements on a single image, which may not be a complete representation of a person.
CONCLUSIONS/IMPLICATIONS: Social perceptions were found to be influenced by retainer design and appearance. This may be a factor in determining retainer choice.
摘要 背景/目的：社会认知会受到牙齿外观的影响。本研究的目的是确定正畸保持器的设计和外观是否会影响对年轻人的社会认知。
在获得伦理批准后，对来自爱尔兰共和国的402名大学生进行了一项经过预试验的问卷调查研究。邀请每位参与者观看一张随机分配的彩色正面微笑照片，照片中的年轻成年男性或女性佩戴五种上颌保持器中的一种，并要求他们根据李克特量表对该对象的社会能力（SC）、心理调适（PA）、智力能力（IA）和吸引力进行评判。使用了每个受试者佩戴以下每种保持器的五张计算机修改标准化照片：Essix、传统霍利保持器、丙烯酸化霍利保持器和Begg保持器；一张没有保持器的图像模拟了粘结保持器（BR）的外观。在SAS®（版本9.2）中进行统计分析。
在SC（P = 0.6741）和PA（P = 0.7217）方面，各保持器之间未发现显著差异。仅在男性受试者中，与传统霍利保持器（P = 0.0018）或丙烯酸化霍利保持器（P = 0.0016）相比，BR外观被认为具有更高的IA。BR外观被认为比Begg保持器更具吸引力（P = 0.0103）。
在本研究中，参与者被要求对单个图像进行主观判断，这可能无法完全代表一个人。
结论/启示：发现社会认知会受到保持器设计和外观的影响。这可能是决定保持器选择的一个因素。
