The purpose of this study was to determine the esthetic importance of different types of developmental enamel defect.
In the first method used, individual subjects from three different populations with less than 0.1, 0.7, and 0.9 ppm fluoride in their drinking water, were asked about the appearance of their teeth and results compared to assessments of clinical photographs made by a single examiner. In the second method used, dentist and lay observers were asked to assess the appearance of the dentition of selected individuals who had a range of enamel defects.
According to the first method, both the size of demarcated opacities and the degree of enamel hypomineralization (TF index) were related to satisfaction with appearance. However, there was no difference in satisfaction with the appearance of the teeth among the three areas included in this study. In the second method, similar types of enamel defects were found to be esthetic stimuli as with the first study, but the dentists responded more strongly to the stimulus of enamel hypomineralization than the lay examiners.
Both demarcated opacities and enamel hypomineralization may be important when assessing differences between populations. Further, esthetic ratings by dentists may not be a suitable means of assessing the esthetic importance of different types of enamel defects.
本研究的目的是确定不同类型发育性釉质缺陷的美学重要性。
在第一种使用的方法中，询问来自三个不同人群的个体（其饮用水中氟含量分别低于0.1、0.7和0.9 ppm）关于其牙齿外观的情况，并将结果与由一名检查者对临床照片进行的评估相比较。在第二种使用的方法中，要求牙医和外行人观察者评估具有一系列釉质缺陷的选定个体的牙列外观。
根据第一种方法，划定的不透明区大小和釉质矿化不足程度（TF指数）均与外观满意度相关。然而，本研究纳入的三个地区在牙齿外观满意度方面没有差异。在第二种方法中，与第一项研究一样，类似类型的釉质缺陷被发现是美学刺激因素，但与外行人检查者相比，牙医对釉质矿化不足刺激的反应更强烈。
在评估人群之间的差异时，划定的不透明区和釉质矿化不足可能都很重要。此外，牙医的美学评分可能不是评估不同类型釉质缺陷美学重要性的合适方法。
