Abstract:
Introduction There is no universally-accepted method for determining the most esthetically pleasing antero-posterior positioning of the jaws. L.F. Andrews proposed using the relationship between the forehead and the maxillary central incisors as a reference. To date, there are no studies investigating Andrews philosophy with changes in forehead position and taking into consideration the ethnicity of the model and evaluator. Purpose To investigate differences in how judges of different ethnicities subjectively evaluate the profile attractiveness of models of different ethnicities when the model profiles are changed at the level of the forehead. Methods Three female models of different races - Caucasian, African American, and Asian - were photographed smiling in profile. The photographs were digitally manipulated to move the forehead anteriorly by 2, 4, and 6mm, and posteriorly by 2mm.31 Caucasian, 28 African American, and 17 Asian lay person evaluators rated the attractiveness of the photographs using a 0-100mm visual analog scale. Results For the Caucasian model, Caucasian evaluators preferred the unaltered photograph over those with forehead positions placed 4 and 6mm anteriorly. For the Asian model, African American evaluators preferred the unaltered photograph over those with forehead positions placed 2 and 6mm anteriorly and Caucasian evaluators preferred the unaltered photograph over that with forehead positioned 2mm anteriorly. For the African American model, Caucasian evaluators preferred the unaltered photograph over those with forehead positions placed 2 and 4mm anteriorly and 2mm posteriorly. Conclusions The results indicate that there is racial variation when assessing facial profile. More data is required to identify potential trends relating AP forehead position and attractiveness.
