This study compared the perception of facial pleasantness and the need for intervention, as assessed by orthodontists, oral and maxillofacial (OMF) surgeons, and laypersons, in people of different ethnicities showing varying degrees of simulated laterognathism. Facial photographs were modified to simulate deviations in the lower face of women of African, Asian and Caucasian descent, ascending in two-degree steps from zero to eight degrees of deviation. Three groups of 20 individuals each (OMF surgeons, orthodontists, and laypersons) assessed the images and rated facial pleasantness on a numerical scale ranging from 0 to 10. The results showed that orthodontists and laypersons rated faces differently only after six and eight degrees of facial change. OMF surgeons rated faces statistically differently from laypersons in all degrees of deviation, and differently from orthodontists in faces with zero, two, and four degrees of deviation. Scores for Caucasian and Asian faces differed only at two degrees of deviation. On the other hand, Caucasian and African faces differed at two and four degrees of deviation, while African and Asian faces differed only at eight degrees. The results suggest that, as a group, OMF surgeons were able to detect all degrees of lower face deviation. Moreover, orthodontists and OMF surgeons seemed to agree in terms of need for facial intervention, and saw that need more often than laypersons. In addition, ethnicity also affected the perception of milder facial changes.
本研究比较了不同种族人群中不同程度模拟小下颌畸形的患者，正畸医生、口腔颌面外科医生和非专业人士对面部美观度的感知和干预需求的评估。通过修改面部照片，模拟出非洲、亚洲和高加索女性的下面部偏差，以两度为步长，从零度到八度逐渐递增。每组有 20 名个体（口腔颌面外科医生、正畸医生和非专业人士）评估这些图像，并在 0 到 10 的数值量表上对面部美观度进行评分。结果表明，只有在面部变化达到六度和八度时，正畸医生和非专业人士才会对不同的面孔做出不同的评价。口腔颌面外科医生在所有偏差程度上都与非专业人士有统计学差异，与正畸医生在零、二和四度偏差时也有差异。在两度偏差时，白人和亚洲面孔的评分存在差异。另一方面，白人和非洲面孔在两度和四度偏差时存在差异，而非洲和亚洲面孔仅在八度偏差时存在差异。结果表明，作为一个群体，口腔颌面外科医生能够检测到所有程度的下面部偏差。此外，正畸医生和口腔颌面外科医生在需要对面部进行干预的问题上似乎达成一致，并且比非专业人士更频繁地看到这种需求。此外，种族也对面部轻微变化的感知产生影响。
