Aesthetic facial perception and need for intervention in laterognathism in women of different ethnicities

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.
