Assessment of the perception of smile esthetics by laypersons, dental students and dental practitioners

Laypersons, dental students and dental professionals had different perceptions of attractiveness when evaluating different modified features, except for diastemas, but with no significant differences between them. Gender was correlated with a very high smile. Age did not correlate with the judgment of the evaluators. There was no difference between the perceptions of laypersons, whether they had received orthodontic treatment or not.
