This study was aimed to evaluate the perception of orthodontists and of lay people about the facial profile and its possible correlation with cephalometrics parameters.
A total of 20 evaluators were divided into two groups (10 orthodontists and 10 people with no relation to such area - lay people). They were asked to evaluate the photographs of 25 young males and of 25 young females, aged 17-24-year-old (mean age of 22.3 years, standard deviation 2.41 years). Photographs were randomly arranged in a photo album. The evaluators rated each photograph by means of a scale ranging from "good" to "deficient" based on the pleasantness of their facial profile. Nasolabial angle, Holdaway's H-line and the distance from H-line to nose tip were measured, in order to verify a possible relation between these soft tissue profile cephalometric measurements and the subjective ratings.
The kappa statistics test showed a concordance of 0.23 among orthodontists and 0.24 among lay people. Regarding the perception of orthodontists and lay people on facial profile, no significant divergence could be detected. For the correlation between cephalometric parameters and subjective ratings, there was a statistically significant correlation between the measures H and H-nose and the rating ascribed to the profile.
It was concluded that smaller the difference from the normal cephalometric pattern, the higher was the rating given to the profile, demonstrating an important relation between subjective and objective criteria.
本研究旨在评估正畸医生和非专业人士对面部轮廓的认知及其与头影测量参数的可能相关性。
共有20名评估者分为两组（10名正畸医生和10名与该领域无关的人员——非专业人士）。要求他们评估25名17 - 24岁年轻男性和25名年轻女性（平均年龄22.3岁，标准差2.41岁）的照片。照片随机排列在一本相册中。评估者根据面部轮廓的美观程度，通过从“好”到“差”的量表对每张照片进行评分。测量鼻唇角、霍尔德韦（Holdaway）H线以及从H线到鼻尖的距离，以验证这些软组织轮廓头影测量值与主观评分之间的可能关系。
kappa统计检验显示正畸医生之间的一致性为0.23，非专业人士之间的一致性为0.24。关于正畸医生和非专业人士对面部轮廓的认知，未发现明显差异。对于头影测量参数与主观评分之间的相关性，测量值H和H - 鼻与对面部轮廓的评分之间存在统计学上的显著相关性。
得出的结论是，与正常头影测量模式的差异越小，对面部轮廓的评分越高，表明主观和客观标准之间存在重要关系。
