The purpose of this study was to evaluate the perception of facial attractiveness presented in a silhouette, profile photograph and in a 3-dimensional photograph to see if there is a correlation of perceived attractiveness between oral surgeons, orthodontists, and lay people. Secondly, if there is an agreement of attractiveness when examining the same subject in silhouette and in photographs, then determine if the subject falls within the ideal norms of facial proportions and soft tissue esthetics used by orthodontists and oral surgeons alike. It was hypothesized that the evaluators perceptions of facial attractiveness when evaluating silhouettes is not closely tied to perceived beauty when looking at facial profile photographs or at three dimensional photographs. The methods involved first identifying female subjects ages 18-35 years of Caucasian or Hispanic descent from beauty pageants. After consents were signed, each subject had their profile photograph and 3-dimensional image made. Next, the photographs were used to fabricate silhouettes for a timed photographic slideshow. Then the evaluators five oral surgeons, five orthodontists, and five laypersonsevaluated the silhouettes based on attractiveness using a visual analog scale as seen in classical studies. Each silhouette was displayed for 10 seconds and rated on a visual analog scale from 1 to 10. Two weeks later, the same evaluators were shown the same group of womens profile photographs for 10 seconds and rated them again on a visual analog scale. Two weeks thereafter this procedure was repeated with a 3-dimensionalimage that rotated 180 degrees for 15 seconds. Again they rated the entire 3-dimensional photograph for level of attractiveness using a visual analog scale. All slides were randomly sorted and the evaluators did not know the ages, pageant history, or even if they were looking at the same persons.
