To determine whether photos or silhouettes are adequate methods for evaluating the esthetic profiles of black subjects and whether black and white evaluators have different preferences for esthetic profiles.
One photographic record of the profile of a black female patient with accentuated dental bimaxillary dentoalveolar protrusion was randomly selected. The image of the patient's profile was altered to produce a series of seven photos and seven silhouettes (a total of 14 images) with different lip positions but uniform distances in relation to the esthetic plane created by Ricketts (line E). Fifty black and 50 white lay evaluators were invited to enumerate the photos and silhouettes, produced according to the lip position, in the order in which they considered most esthetically pleasing.
The number of preferences found to be within the esthetic norm was slightly higher among the photographs than among the silhouettes; the esthetic profile with a deviation of -2 mm from line E was elected as the most attractive, and the esthetic pattern with a deviation of +6 mm from the normal line E was considered the least attractive. There were no statistically significant differences between the preferences related to the variables race, sex, and educational background.
The esthetic attractiveness of the facial profiles of black subjects in photos and silhouettes was evaluated in a similar manner among black and white evaluators. Among both black and white evaluators, the greatest preference was for the slightly concave profile, which was within the limit considered standard.
确定照片或剪影是否为评估黑人受试者美学侧貌的适当方法,以及黑人和白人评估者对美学侧貌是否有不同偏好。
随机选择一张患有明显双颌牙牙槽前突的黑人女性患者侧貌的摄影记录。改变患者侧貌图像,以生成一系列七张照片和七个剪影(共14张图像),唇部位置不同,但相对于由里氏(E线)创建的美学平面距离一致。邀请50名黑人和50名白人普通评估者按照他们认为最美观的顺序对根据唇部位置制作的照片和剪影进行排序。
发现照片中符合美学标准的偏好数量略高于剪影;与E线偏差-2mm的美学侧貌被选为最具吸引力的,与正常E线偏差+6mm的美学模式被认为最缺乏吸引力。在与种族、性别和教育背景等变量相关的偏好之间没有统计学上的显著差异。
黑人和白人评估者对照片和剪影中黑人受试者面部侧貌的美学吸引力评估方式相似。在黑人和白人评估者中,最受青睐的是略凹的侧貌,其在被认为是标准的范围内。
