A smile is defined as a universal welcome. The perception of smile attractiveness is affected by the persons' social background and their own experiences. The existing literature states that orthodontists, restorative dentists, and laypersons have different opinions.
The aim of this study is to compare the perception of orthodontists, restorative dentists, and laypersons regarding smile esthetics.
A survey-based study was conducted. The target population was orthodontists, restorative dentists, and laypersons in Saudi Arabia. An electronic survey that included digitally altered photographs representing different smile parameters was designed by an Adobe Photoshop Certified Expert. Participants were asked to choose the most attractive smile in each question.
Unilateral changes in the width or length of the central incisors were the least attractive among the three groups. About 38%, 48%, and 41% of the participating orthodontics, restorative dentists, and laypersons, respectively, found that wider buccal corridors were more attractive. Moreover, 27% of the laypersons found the reversed smile arc to be attractive.
The tolerance level in evaluating the asymmetry and the width of the buccal corridors was similar for the three groups. Laypersons were less sensitive to the deviations from the ideal in the smile arc and the amount of lower lip coverage of the incisors.
Understanding the differences in the perception of smile attractiveness among orthodontists, restorative dentists and laypersons will undoubtedly be beneficial in diagnosis, setting treatment objectives and treatment planning.
微笑被定义为一种通用的欢迎方式。对微笑吸引力的认知受个人社会背景及自身经历的影响。现有文献表明，正畸医生、修复牙医和外行人有不同的看法。
本研究的目的是比较正畸医生、修复牙医和外行人对微笑美学的认知。
开展了一项基于调查的研究。目标人群为沙特阿拉伯的正畸医生、修复牙医和外行人。由一位Adobe Photoshop认证专家设计了一项电子调查，其中包括代表不同微笑参数的数字修改照片。要求参与者在每个问题中选择最具吸引力的微笑。
三组中，中切牙宽度或长度的单侧变化最缺乏吸引力。分别约有38%、48%和41%的参与研究的正畸医生、修复牙医和外行人认为较宽的颊间隙更具吸引力。此外，27%的外行人认为反笑弧有吸引力。
三组在评估不对称性和颊间隙宽度时的容忍度水平相似。外行人对微笑弧度偏离理想状态以及下唇覆盖切牙的程度不太敏感。
了解正畸医生、修复牙医和外行人对微笑吸引力认知的差异无疑将有助于诊断、设定治疗目标和制定治疗计划。
