Study of the Influence of Female Facial Profile Angles on the Preference of On-line Evaluators
Rodrigo Martins Boos · Advisor: Prof. Ernani Menezes Marchioro · Porto Alegre, Brazil, 2001
A pioneering study in Brazil: 2,041 on-line evaluations used in the formal analysis — and over 4,800 opinions collected overall — to measure, with real statistics, which female facial profile angles the public finds most pleasing.
About the study
Eleven images of a female facial profile, digitally altered in controlled increments of a few millimeters, were shown to thousands of evaluators over the Internet — an uncommon research tool for dental studies in the early 2000s. Results showed statistically significant preference values for the Nasolabial, Mentolabial, Labial, and Facial angles, along with differences in preference by evaluator sex, region, ethnicity, and occupation.
