Methods: The sample consisted of 105 persons with 35 subjects by group evaluator. To carry out the study was used a photography of the face during the smile of a woman with parameters close to ideal, which was modified by a computer specialist by the Adobe Photoshop program on 3 different levels of gingival exposure (EG): 0mm, +2 mm, +4 mm and 3 different types of buccal corridor (CB): narrow, wide and null. The perception of the three groups of raters was determined by a visual analog scale (VAS). Results: They found statistically significant differences among groups (Anova-Tukey; p< 0.05). Laypersons, graduates and residents prefer smiles with EG 0mm and CB narrows-null. Considering the smiles with EG 4mm and CB wides as unattractive smiles. Conclusion: CB minimal or narrow and EG 0mm; is a preferred aesthetic characteristic shared by most laypersons, while EG 4mm and CB wide should be included in the list of issues during diagnosis and orthodontic treatment plan.
