an attractive smile helps people feel more self-confident and look younger. One of the more controversial aspects of smile attractiveness pertains to buccal corridor size. There is no previous study by those with artistic knowledge that has assessed the asthetic considerations of buccal corridor size. The purpose of this study was to observe whether the size of buccal corridors has an impact on smile attractiveness evaluated by lay people, dental students, and art students.
colored post-treatment photograph with posed smiles of two subjects (one male, one female) were selected. The maxillary posterior dentitions were digitally altered to produce different buccal corridor sizes: narrow (28% buccal corridor), medium-narrow (22% buccal corridor), medium-broad (10% buccal corridor), and broad (2% buccal corridor). The 5 images of each subject were paired into 11 possible combinations and presented to three group: art students, dental students, and lay people, who compared the two images in each pair of smile attractiveness. The statistical test used were Wilcoxon signed rank and Mann-Whitney test.
minimal and excessive buccal corridors were the least attractive when judged by three groups. All groups preferred smaller buccal corridors for the male subject and larger buccal corridors for the female subject. No significant judging differences were found between male and female judges from among art and dental students.
minimal or excessive buccal corridor should be included in the problem list during orthodontic diagnosis and treatment planning.
迷人的微笑有助于人们增强自信并显得更年轻。微笑吸引力中较具争议的一个方面与颊间隙大小有关。此前尚无具备艺术知识的人员进行过评估颊间隙大小美学考量的研究。本研究的目的是观察颊间隙大小是否会对由外行人、牙科学生和艺术学生评估的微笑吸引力产生影响。
选取了两名受试者（一男一女）治疗后的彩色摆拍微笑照片。对上颌后牙列进行数字修改，以产生不同的颊间隙大小：窄（颊间隙28%）、中窄（颊间隙22%）、中宽（颊间隙10%）和宽（颊间隙2%）。将每个受试者的5张图像配对成11种可能的组合，并展示给三组人员：艺术学生、牙科学生和外行人，他们比较每对微笑吸引力中的两张图像。使用的统计检验方法是威尔科克森符号秩检验和曼 - 惠特尼检验。
三组人员评判时，最小和过大的颊间隙最缺乏吸引力。所有组都偏好男性受试者的颊间隙较小，女性受试者的颊间隙较大。在艺术学生和牙科学生中，男性和女性评判者之间未发现显著的评判差异。
在正畸诊断和治疗计划中，应将最小或过大的颊间隙列入问题清单。
