Abstract

Background:

A smile is defined as a universal welcome. The perception of smile attractiveness is affected by the persons' social background and their own experiences. The existing literature states that orthodontists, restorative dentists, and laypersons have different opinions.

Aims:

The aim of this study is to compare the perception of orthodontists, restorative dentists, and laypersons regarding smile esthetics.

Materials and Methods:

A survey-based study was conducted. The target population was orthodontists, restorative dentists, and laypersons in Saudi Arabia. An electronic survey that included digitally altered photographs representing different smile parameters was designed by an Adobe Photoshop Certified Expert. Participants were asked to choose the most attractive smile in each question.

Results:

Unilateral changes in the width or length of the central incisors were the least attractive among the three groups. About 38%, 48%, and 41% of the participating orthodontics, restorative dentists, and laypersons, respectively, found that wider buccal corridors were more attractive. Moreover, 27% of the laypersons found the reversed smile arc to be attractive.

Conclusion:

The tolerance level in evaluating the asymmetry and the width of the buccal corridors was similar for the three groups. Laypersons were less sensitive to the deviations from the ideal in the smile arc and the amount of lower lip coverage of the incisors.

Clinical Significance:

Understanding the differences in the perception of smile attractiveness among orthodontists, restorative dentists and laypersons will undoubtedly be beneficial in diagnosis, setting treatment objectives and treatment planning.
