Measuring the mind: Brain imaging of the psychological impairment related to malocclusion

我们的目的是评估佩戴正畸矫治器时看到他人面部的眼球运动，并评估托槽对面部吸引力的影响。6张面部照片，佩戴3种家电；透明（CB）和金属（MB）支架以及替代器具（AA）按随机顺序各显示1分钟。在观察面部时测量眼球运动。我们分析了总凝视时间和凝视次数。每张照片被分成三个区域，眼睛、鼻子和嘴巴。我们对器具和面积进行了三向方差分析，对于总凝视时间和凝视次数，是否有显著差异取决于器具的类型。MB组的总注视时间高于CB组和AA组。在凝视次数上没有显著差异。这表明，根据家电的类型，有一个独特的模式来评估吸引力。

We aimed to estimate the eye movement of seeing the faces of others wearing orthodontic appliance and evaluate effects of brackets on facial attractiveness. Six facial photos, worn 3 types of appliances; the clear (CB) and metal (MB) brackets, and alternative appliances (AA), were shown for 1 minute each in random order. The eye movements during the observation of the faces were measured. We analyzed total gaze time and count of gaze. Each photograph was divided into three regions, eyes, nose, and mouth. We conducted three-way ANOVA of appliances and area, regarding total gaze time and the count of gaze, whether there is a significant difference depending on the type of appliances. The MB photos showed higher values in the total gaze time to the area of mouth than CB and AA photos. There was no significant difference in the count of gaze. It is suggested that there is a distinctive pattern to evaluate attractiveness according to the types of appliances.
