Abstract
Background: One of the most important goals of orthodontic and orthognathic surgery treatment on the profile region
is to improve facial aesthetics. Because orthodontics primarily affects the face, we focus on the chin. The aim of this
study was to evaluate the effects of chin position on facial profile attractiveness and harmony among laypeople, dentists and orthodontists.
Material and methods: A digital portrait of adult woman was generated by artificial intelligence (AI) for the study.
The image was digitally altered using Adobe Photoshop to create 7 images, and presented to 40 orthodontists, 40 dentists, and 40 laypeople for evaluation of their perception of facial profile attractiveness on a visual value rating scale.
Results: The study results showed that in images 1 through 7, where the chin moved in the sagittal plane, statistically
significant differences were found between the study groups, with the exception of images 1, 5, and 6 in question 1,
and images 3, 4, and 5 in question 2, and images 1, 3, 4, 5, and 7 in question 3.
Conclusions: Laypeople, dentists and orthodontists rated the retrusive chin as more attractive than the protrusive of
the chin.
