Abstract

Objective: This study aimed to evaluate how dental practitioners and laypersons differ in their perception of altered smile aesthetics based on viewing images of a digitally manipulated smile.

Materials and Methods: A photograph with ideal smile characteristics was selected and digitally manipulated to create changes in maxillary dental midline shift, inter-incisor diastema, crown width of the lateral incisor, crown length of central incisor and gingival exposure.

To assess the attractiveness of the pictures, a score from 1 to 10 was given by different evaluators. The response were then analyzed and processed with SPSS software version 17.0 using the Kriskal Wallis Test and the Mann Whitney Test.

Results: Orthodontists were more critical and gave lower scores than dentists and

laypeople when evaluating different altered smiles.

Age, gender and years of dental practice showed no signification correlation with the attributed scores, contrary to the educational level.

The unattractive smile are those with 3mm midline diastema between the maxillary central incisors and with 3mm decrease of the maxillary left central incisor crown lenght.
