ABSTRACT The aim of this study was to evaluate the attractiveness of different gingival smile on zeniths by laypeople, dentists and orthodontists. Five posed photographs of 5 patients were taken in a standardized manner. Each photo was digitally manipulated in Keynote software in the gingival zenith region in increments of 0.5 to 1 mm in maxillary central and lateral incisors symmetrically and asymmetrically, in 9 different ways for each photo. Subsequently were placed on a website, so evaluators could observe them and vote according to their esthetic perception from 1 to 10, 1 being the least attractive and 10 the more attractive. The entire database was stored and available to the researcher. Data were collected and to compare the changes of smiles among laypeople, dentists and orthodontists, the Kruskal-Wallis test was used for comparison and each smile change between younger and older groups it was used the Mann-Whitney test. It was found that the results for the laypeople, asymmetric changes from 1mm in maxillary central incisor were more significant than the lateral incisors. In general, dentists and orthodontists were more critical in evaluating and perceiving the changes of the gingival zenith and zenith changes greater than 1mm were noted in the attractiveness of the smile, both by laypeople, dentists and orthodontists.
