To compare the effect of various degrees of decalcification after orthodontic treatment (white spot lesions) on orthodontists', general dentists', and laypersons' ratings of smile esthetics.
Eight photographs representing incrementally altered tooth decalcification lesions of maxillary anterior teeth ranging from mild to severe were shown randomly to the study participants. Photographs were rated by a matched sample of orthodontists (N = 42), general dentists (N = 52), and laypeople (N = 58). A visual analogue scale (VAS) was used to assess perceptions of smile esthetics.
The three groups of raters could distinguish between different decalcification levels. Raters gave more negative scores as the decalcification level increased.
The three groups of raters were able to distinguish between various degrees of decalcification lesions. General dentists were the most critical of all groups when rating decalcification lesions.
比较正畸治疗后（白垩斑）不同程度脱矿对正畸医生、全科牙医和非专业人士对微笑美观评价的影响。
将 8 张上颌前牙脱矿病变逐渐加重的照片随机呈现给研究参与者。照片由正畸医生（N=42）、全科牙医（N=52）和非专业人士（N=58）的匹配样本进行评分。采用视觉模拟评分（VAS）评估对微笑美观的感知。
三组评价者能够区分不同程度的脱矿。随着脱矿程度的增加，评分者给出的分数越低。
三组评价者能够区分不同程度的脱矿病变。在评价脱矿病变时，全科牙医是最严格的一组。
