The aim of the present investigation was to perform an international multicenter comparison of dental appearance as evaluated by dentists, dental technicians, and nondental subjects.
The participants were drawn from three groups: 203 dentists, 197 dental technicians and 254 nondental subjects. The methods developed in a previous study in Sweden were applied again in seven centers located in six countries. A questionnaire, accompanied by five sets of computer-manipulated images portraying one man and one woman, was used to prompt and record responses to different aspects of dental appearance and function.
The questionnaire revealed that both the dental appearance and function of teeth were important to most of the participants, but three quarters of the participants did indicate that good dental function was more important that esthetics. More women (30%) than men (18%), however, placed greater importance on appearance. Age or gender did not influence judgments of the computer-manipulated images, although judgments did vary greatly within the three groups and between the centers. Nonetheless, highly colored teeth were preferred more often by nondental subjects than by dentists or dental technicians.
Computer-aided image manipulation shows promise as a method for investigating the significance of dental-related beliefs, especially those relating to esthetics, in different population groups. The evaluation of dental appearance and function in this study indicated that dental function is held in greater regard, and that the significance of dental appearance varies widely among dentists, dental technicians, and nondental subjects.
本研究旨在对牙医、牙科技师和非牙科专业人员对牙齿外观的评价进行国际多中心比较。
参与者分为三组：203名牙医、197名牙科技师和254名非牙科专业人员。瑞典之前一项研究中开发的方法在六个国家的七个中心再次应用。一份问卷，附带五组电脑处理过的描绘一男一女的图像，用于引导并记录对牙齿外观和功能不同方面的回答。
问卷显示，牙齿外观和功能对大多数参与者都很重要，但四分之三的参与者确实表示良好的牙齿功能比美观更重要。然而，比起男性（18%），更多女性（30%）更看重外观。年龄或性别并未影响对电脑处理图像的判断，尽管三组内部以及各中心之间的判断差异很大。尽管如此，比起牙医或牙科技师，非牙科专业人员更常偏好颜色较深的牙齿。
计算机辅助图像处理作为一种调查不同人群中与牙齿相关信念（尤其是与美观相关的信念）重要性的方法显示出前景。本研究中对牙齿外观和功能的评价表明，牙齿功能更受重视，且牙齿外观的重要性在牙医、牙科技师和非牙科专业人员中差异很大。
