目的
本调查的目的是对牙医、牙科技术人员和非牙科受试者评估的牙齿外观进行国际多中心比较。
材料和方法
参与者分为三组：203 名牙医、197 名牙科技师和 254 名非牙科受试者。瑞典先前研究中开发的方法在位于六个国家的七个中心再次得到应用。一份调查问卷，附有五组描绘一名男性和一名女性的计算机处理图像，用于提示和记录对牙齿外观和功能不同方面的反应。
结果
调查问卷显示，牙齿外观和牙齿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，更多的女性（30%）比男性（18%）更加重视外表。年龄或性别并不影响对计算机处理图像的判断，尽管三组内部和中心之间的判断确实存在很大差异。尽管如此，与牙医或牙科技师相比，非牙科受试者更喜欢颜色深的牙齿。
结论
计算机辅助图像处理有望作为一种方法来研究不同人群中与牙科相关的信念（尤其是与美学相关的信念）的重要性。本研究中对牙齿外观和功能的评估表明，人们更重视牙齿功能，并且牙齿外观的重要性在牙医、牙科技师和非牙科受试者之间存在很大差异。
PURPOSE
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.
MATERIALS AND METHODS
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.
RESULTS
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.
CONCLUSION
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.
