Abstract
The purpose of this study was to compare preferred facial profiles rated by different age groups. An average profile of each gender was constructed from subjects with normal occlusions. Each average profile was located in the centre, and then the lips were protruded or retruded in six 1 mm increments in each direction. 70 lay people were divided into 3 groups: young adult (20-39 years); middle-aged (40-54 years); and senior (55-70 years). They were asked to rank their 3 most preferred profiles for each gender. The distribution of the most pleasing profile was compared according to age groups by the Kruskal-Wallis test and according to the rater's gender by the Mann-Whitney U-test. There was a significant difference between the three age groups regarding the preferred male and female profiles (P < 0.001). Both the middle-aged and the senior groups tended to select a slightly more retruded lip/flat profile than the young adult group. There was no gender dimorphism in the selection of the preferred profile. The young adult group preferred the straight profile while the middle-aged and senior groups favoured the slightly retruded profile. This may provide useful information for treatment planning in orthodontics and orthognathic surgery. © 2012 International Association of Oral and Maxillofacial Surgeons.
