Abstract
Background: Facial esthetics plays a major part in diagnosis and treatment planning in orthodontics. One aspect of facial esthetics that orthodontist can drastically change, for better or worse, is that of lip position. What is considered esthetic, however, may vary from person to person based on a multitude of variables. Hypothesis: It is hypothesized that the esthetics of lip protrusion differs with age, with a younger layperson preferring a more protrusive lip position than an older person's ideal lip protrusion. Methods: 208 lay people, ages 12+, with no background in the dental field, were surveyed and asked to rank from 1-4 a series of profiles with different lip positions in relation to the E-line, 1 being the most esthetic, 4 being the least esthetic. The respondents were then divided into different age ranges and their responses analyzed. Results: The 12-19 age group chose the profile with the lip position on the e-line as most esthetic. Age groups 20-39, 40-59, and 60+ all chose the profile that was 2mm behind e-line as the most esthetic.
