Abstract

by Elvi Marie Barcoma, D.D.S.

A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University

Virginia Commonwealth University, 2015

Major Director: Bhavna Shroff, D.M.D., M.Dent.Sc, Program Director, Orthodontics

Objective: To determine if people of different racial backgrounds prefer different amounts of

maxillary incisor labiolingual inclination from a smiling profile view.

Materials and Methods: An electronic survey was created with smiling profile images of an African-American female and a White female with varying degrees of maxillary incisor labiolingual inclination. Images were ranked from most attractive to least attractive.

Results: There was no statistically significant difference in the overall preference for maxillary incisor labiolingual inclination between African-American and White evaluators or between genders. The estimated optimal incisal inclination across races was -8.1°.

Conclusions: There was no clinically significant difference in the estimated optimal inclination across races or between genders. The average of the top three maxillary incisor inclinations ranged between -10° and -5°. The majority of evaluators preferred retroclined maxillary incisors over proclined maxillary incisors.
