Facial and dental appearance influences how individuals are perceived by others.
This study aimed to determine whether young people make judgements about other young people with visible enamel opacities.
Focus group findings were used to develop a social attribute questionnaire to capture young people's dental appearance-related judgements. 547 pupils (aged 11-15 years), from two different schools, participated in the study. Half the participants were given full-face photographs of a boy and girl without an enamel defect, and the other half were given the same two photographs with the subjects' incisors digitally modified to show enamel opacities. Participants completed the attribute questionnaire to rate the photographic subjects according to six positive and five negative descriptors using a four-point Likert scale. The total attribute score (TAS) could range from 11 (most negative) to 44 (most positive).
TAS was significantly lower for photographic subjects with enamel defects compared to the same subject with normal enamel appearance (P < 0.001, one sample t-test). Gender had a significant impact on TAS, with boys making more negative judgements than girls. Age and socio-economic status did not have an effect.
Young people may make negative psychosocial judgements on the basis of enamel appearance.
面部和牙齿外观会影响他人对个体的看法。
本研究旨在确定年轻人是否会对有明显牙釉质不透明的其他年轻人做出评判。
焦点小组的研究结果被用于开发一份社会属性问卷，以获取年轻人与牙齿外观相关的评判。来自两所不同学校的547名学生（年龄在11至15岁之间）参与了该研究。一半参与者收到的是没有牙釉质缺陷的一男一女的正面照片，另一半收到的是同样的两张照片，但照片中人物的门牙经过数字修改以显示牙釉质不透明。参与者完成属性问卷，使用四点李克特量表根据六个正面和五个负面描述词对照片中的人物进行评分。总属性得分（TAS）范围可以从11分（最负面）到44分（最正面）。
与牙釉质外观正常的同一人物相比，有牙釉质缺陷的照片人物的TAS显著更低（P < 0.001，单样本t检验）。性别对TAS有显著影响，男孩做出的负面评判比女孩更多。年龄和社会经济地位没有影响。
年轻人可能会基于牙釉质外观做出负面的社会心理评判。
