Abstract

ABSTRACTOBJECTIVE: This study aims at comparing the perception of orthodontists, maxillofacial surgeons, visual artists and laypersons when evaluating the influence of sagittal position of the mandible - in lateral view - in facial attractiveness; at a job hiring; and in the perception of socioeconomic profile. METHODS: A black male, a white male, a black female and a white female with harmonic faces served as models to obtain a facial profile photograph. Each photograph was digitally manipulated to obtain seven facial profiles: an ideal, three simulating mandibular advancement and three simulating mandibular retrusion, producing 28 photographs. These photographs were evaluated through a questionnaire by orthodontists, maxillofacial surgeons, visual artists and laypersons.RESULTS: The anteroposterior positioning of the mandible exerted strong influence on the level of facial attractiveness, but few significant differences between the different groups of evaluators were observed (p < 0.05).CONCLUSIONS: The profiles pointed as the most attractive were also pointed as more favorable to be hired to a job position and pointed also as having the best socioeconomic condition.

Highlights

Facial esthetics has been researched for a long time.Some studies show that people with attractive dentition are considered more intelligent, more popular and more employed than other people with less attractive teeth.[1,2,3] In addition, the desire to improve facial esthetics is one of the main reasons why people seek orthodontic treatment.[4,5,6]Some authors believe that reaching the esthetic standard desired by the patient is a challenging task for dentists due to the subjective nature of the evaluation and perception of facial esthetics.[7]
All the criteria prescribed by Resolution 466/12 of the National Health Council (NHC), which deals with ethics in research with human beings were obeyed in implementing this study
The facial profile was obtained by turning the positioner to the zero degree point, where the two positioners were in the same distance to the camera, up to 85o, with the aim of obtaining a real outline of the profile

Summary

Introduction

Some studies show that people with attractive dentition are considered more intelligent, more popular and more employed than other people with less attractive teeth.[1,2,3] In addition, the desire to improve facial esthetics is one of the main reasons why people seek orthodontic treatment.[4,5,6]. Some authors believe that reaching the esthetic standard desired by the patient is a challenging task for dentists due to the subjective nature of the evaluation and perception of facial esthetics.[7] According to Kumar et al.[8] and Cochrane et al.[9], professionals and laypersons perceive facial esthetics differently, with laypersons demonstrating a larger variation on what is considered to be attractive. Other authors[7,10,11] have concluded that there is not any difference between professionals and laypersons when it comes to the perception of facial esthetics
