目得：这项研究是为了确定公众的喜好五个审美变化，与人口统计数据，如年龄，性别，居住国，和race.MATERIALS和方法：使用照片编辑软件，五对图像与前牙的变化被放在一个网页上的形式，收集人口统计数据和排名的图像对的目标。通过发送大量电子邮件征求意见，其中附有简短的研究说明和访问网页的邀请。结果：45个国家的2185名计算机用户的有效回答被制成表格并进行逻辑回归分析（α = 0.05）。由于大多数国家的受访者数量较少，因此仅分析了美国和加拿大（n = 1934）的答复。收集的变量包括出生日期、性别、种族或民族背景以及最后一次牙科就诊。分析表明，不同的变量对不同的问题有显着性。最后一次牙科就诊以及性别和种族的相互作用在任何模型中均不显著。最强的偏好有关牙间隙和中线移位和最弱的有关白度和比例。最大的少数意见是直的embrasures。统计学显著性差异归因于年龄、性别和种族。女性在所有条件下都有更强的偏好。年龄小于40岁的受访者有更强的偏好，白度和对diastema，和白人强烈拒绝diastema.Clinical Significance：这项研究提供了有关公众的喜好在美学牙科一些常见的条件的指导方针。
PURPOSE: This study was undertaken to determine the public's preferences for five esthetic variations, with the goal of linking preferences to demographic data such as age, gender, country of residence, and race.MATERIALS AND METHODS: Using photo-editing software, five pairs of images with anterior tooth variations were put on a Web page with forms to collect demographic data and ranking of the image pairs. Opinions were solicited by sending out a large number of e-mails with a short study description and an invitation to access the Web page. The responses were tabulated and analyzed with logistic regression (alpha = 0.05).RESULTS: Valid responses were received from 2185 computer users in 45 countries. Because of the small number of respondents from most countries, only the responses from the United States and Canada (n = 1934) were analyzed. Variables collected were birth date, gender, race or ethnic background, and last dental visit. Analysis indicated that different variables were significant for different questions. Last dental visit and the interaction of gender and race were not significant in any of the models. Strongest preferences concerned diastema and midline shift and the weakest concerned whiteness and proportion. The largest minority view was the straight embrasures. Statistically significant differences were attributable to age, gender, and race. Females had stronger preferences in all conditions. Respondents younger than 40 years of age had stronger preferences for whiteness and against diastema, and whites strongly rejected the diastema.CLINICAL SIGNIFICANCE: This study provides guidelines about the public's preferences concerning some commonly encountered conditions in esthetic dentistry.
