The present study had a convenience sample with 236 laypeople and 242 dentists who completed an online questionnaire to choose the most attractive image among six pairs for comparison. Control image: symmetric (parallelism between occlusal plane (OP), commissural line (CL), and interpupillary line (IL)). Change of Control, obtaining three images with a 3-degree inclination of the labial commissures. Image A: OP parallel to IL; Image B: OP parallel to CL; Image C: OP at 1.5 degree mean angulation between IL and CL. Non-parametric comparison (IBM© SPSS Statistics vs. 27.0, < 0.05). The "Dentists" group's decreasing order of preference (attractiveness) of the images is: Control > A > C > B ( < 0.05). In the "Lay" group, it is: Control > A > (C not ≠ B). Dentists significantly prefer more the Control and Image A than laypeople ( < 0.001). Sex (single exception in laypeople), age, and dentist's area of activity did not interfere in the perception of attractiveness. Dentists and laypeople preferred the Control when compared to images with CL canted. In the existence of CL inclination, the preference of the groups was the IL as a reference for OP orientation, with the mean angulation or coincident with the CL being considered less aesthetic.
本研究采用方便样本，共有 236 名非专业人士和 242 名牙医完成了在线问卷，从六对对比图像中选择最具吸引力的图像。对照图像：对称（咬合平面（OP）、口角线（CL）和瞳孔间线（IL）之间的平行度）。对照改变，获得三个唇口角以 3 度倾斜的图像。图像 A：OP 与 IL 平行；图像 B：OP 与 CL 平行；图像 C：OP 在 IL 和 CL 之间呈 1.5 度平均角度。非参数比较（IBM© SPSS Statistics vs. 27.0， < 0.05）。“牙医”组对图像的偏好（吸引力）递减顺序为：对照> A > C > B（ < 0.05）。在“非专业人士”组中，顺序为：对照> A >（C 不等于 B）。牙医比非专业人士更倾向于选择对照和图像 A（ < 0.001）。性别（非专业人士中有一个例外）、年龄和牙医的活动领域没有影响吸引力的感知。牙医和非专业人士更喜欢对照图像，而不是 CL 倾斜的图像。在 CL 倾斜存在的情况下，两组的偏好是以 IL 作为 OP 定向的参考，认为平均角度或与 CL 一致的角度不太美观。
