Both were considered pleasant smiles, following some principles of an ideal smile. Images were digitally altered to create tooth wear asymmetries on the maxillary left central and lateral incisor in 0.5 mm increments. Final images were arranged randomly into a photo album and were shown to 86 judges (43 orthodontists and 43 laypersons). Judges were asked to evaluate the attractiveness of the images according to a visual analog scale. Data were statistically analyzed using one\u2010way analysis of variance (ANOVA) with the Tukey's post hoc test and the Student <jats:italic>t<\/jats:italic> test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was no statistically significant difference in the mean esthetic scores of the full\u2010face and close\u2010up smile photos. The most attractive smiles were those without asymmetries and those with 0.5 mm wear in the lateral incisor, whereas the least attractive ones were those with 1.0\u20101.5 mm wear in the central incisors. Statistically significant difference was found in the mean scores given by the judges in most cases. The orthodontists were more critical and assigned lower scores than the laypersons.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The presence of maxillary incisor asymmetries is a critical factor influencing the perception of smile esthetics.
