Facial Rejuvenation and Surgery Techniques

To evaluate the degree of perception of laypersons, professionals, and dental students, regarding the aesthetic appearance of the smile in cases of gingival plastic surgery of the maxilla for correction of a gingival smile, by examining alterations in photographs.Alterations were made to an extraoral front-view-photograph of a gingival smile in normal occlusion, by gingival recontouring of the maxilla, simulating a gingival plastic surgery procedure to diminish gingival exposure. For this purpose, specific image-manipulation program (Adobe-Photoshop-Software-CS3) was used. Images were printed on photographic-paper, attached to questionnaire, distributed among laypersons, professionals, and dental students to evaluate degree of aesthetics (n = 150). To evaluate degree of aesthetics, an attractiveness scale was used, with 0 representing hardly attractive, 5 for attractive, and 10 for very attractive. Differences between examiners were examined by Mann-Whitney test. All the statistics were performed with a confidence level of 95 per cent.Both dental professionals and students and laypersons were capable of identifying alterations resulting from gingival plastic surgery. In all evaluated groups, they demonstrated that large gingival extension does not always affect aesthetic appearance of the smile, and maxillary incisors not being much visualized is characterized as hardly attractive, with statistically lower scores being attributed (P < 0.05).According to aesthetic parameters, the presence of the gingiva is important in the composition of the smile, however, only when exposed to small extent.
