The purposes of this study were to rate the attractiveness of different smile variables, to compare the perception of Jordanian laypeople, general practitioners, and orthodontists to altered smile aesthetics, and to identify the threshold where different variables begin to impair smile aesthetics. A smiling photograph of a female dental student was selected and digitally manipulated to create changes in buccal corridor space (BCS), the amount of gingival display, and the midline diastema. These altered images were rated by three groups of Jordanians: 200 laypeople (100 females and 100 males), 200 general practitioners (100 females and 100 males), and 160 orthodontists (40 females and 120 males). Smile aesthetics scores were calculated and comparisons between groups were performed using the univariate general linear model. The results showed that profession and gender affected BCS and midline diastema attractiveness ratings (P<0.001). Wide BCSs, a gingival display of more than 2 mm, and the presence of a midline diastema of any size were rated as unattractive by all groups.
本研究的目的是评估不同微笑变量的吸引力，比较约旦非专业人士、全科医生和正畸医生对改变后的微笑美学的感知，并确定不同变量开始影响微笑美学的阈值。选择了一名女性牙科学生的微笑照片，并对其进行数字处理，以改变颊廊空间（BCS）、牙龈显露量和中线间隙。这三组约旦人对这些改变后的图像进行了评分：200 名非专业人士（100 名女性和 100 名男性）、200 名全科医生（100 名女性和 100 名男性）和 160 名正畸医生（40 名女性和 120 名男性）。计算了微笑美学评分，并使用单变量一般线性模型对组间进行了比较。结果表明，职业和性别影响 BCS 和中线间隙吸引力评分（P<0.001）。宽的 BCS、超过 2 毫米的牙龈显露和任何大小的中线间隙都被所有组评为不吸引人。
