“…They also agree with data from the studies of Cracel-Nogueira, Pinho 4 , Guo et al 10 , Kaya, Uyar 11 , Oshagh et al 12 , Pithon et al 14 and Talic et al 3 , which reported that dentists are more critical than laypersons.…”

“…Currently, many studies have shown that the characteristics of an aesthetic smile, according to dental professionals and laypersons, are different. Some of these studies have worked with computer modified photographs and are shown to be an effective method for evaluating the different perceptions 3,4,6,[9][10][11][12]14 . Analyzing the aesthetic perception of patients and professionals in relation to increased gingival display (gingival smile), it was observed that, according to general practitioner dentists and periodontists, 1.5 mm of gingival display compromises the aesthetics of the smile.…”

“…It was digitally modified on the gingival margin of the upper anterior teeth, by a professional photographer using the Adobe Photoshop software (Adobe Systems Inc., San Jose, California), to create a gingival smile, using a similar method to that adopted in other work 3,4,6,[9][10][11][12][13][14][15] . The photograph was modified every 0.5 mm up to a level of 2.5 mm, totaling six photos, as shown in Figure 1.…”

ResumoIntrodução: Cirurgiões-dentistas têm mostrado interesse em conhecer novos meios para a construção de sorrisos mais atraentes, porém com pouca preocupação em entender os motivos pelos quais o paciente está insatisfeito. Objetivo: Avaliar a percepção estética de pessoas leigas em odontologia em comparação com dentistas clínicos gerais e periodontistas quanto ao sorriso gengivoso, e comparar esta percepção estética do gênero masculino e feminino. Metodologia: Foi realizada fotografia de um sorriso padrão e modificada digitalmente para criar as condições periodontais de sorriso gengivoso de 0,5mm até 2,5mm. As fotografias foram avaliadas por 150 indivíduos (25-65 anos), 81 do gênero feminino e 69 do masculino, divididos em três grupos: 50 leigos, 50 clínicos gerais e 50 periodontistas. A avaliação foi realizada por escala analógica visual. Os testes de avaliação estatística utilizados foram Quiquadrado de Person, t de Student, ANOVA e Newman-keuls. Resultado: As percepções estéticas entre os profissionais são semelhantes, e percebem mudanças na estética do sorriso mais sutis que leigos. Os clínicos gerais e os periodontistas foram sensíveis de forma semelhante às mudanças geradas no sorriso gengivoso quando estas chegaram a 1,5 mm, enquanto que os leigos só perceberam quando estas modificações chegaram a 2,5 mm. Em todos os grupos não houve diferença significativa da percepção estética de avaliadores do gênero masculino e feminino. Conclusão: A percepção estética do sorriso gengivoso entre dentistas clínicos gerais e periodontistas foi semelhante, e os profissionais de odontologia foram mais exigentes do que os leigos. Não houve diferença na percepção estética feminina e masculina.Descritores: Gengiva; percepção; estética; fotografia; sorriso. Abstract Introduction:Dentists have shown interest in learning new techniques to create more attractive smiles, but with little concern for understanding the reasons why the patient is dissatisfied. Objective: To evaluate the aesthetic perception of laypersons in dentistry in comparison with general practitioner dentists and periodontists regarding the gingival smile, and to compare this aesthetic perception between the male and female genders. Methodology: A photograph of a standard smile was taken and was digitally modified to create the periodontal conditions of a gingival smile from 0.5 mm to 2.5 mm. The photographs were judged by 150 individuals (25-65 years of age), 81 female and 69 male, divided into three groups: 50 laypersons, 50 general practitioners and 50 periodontists. The evaluation was performed using a visual analog scale. The statistical evaluation tests used were the Pearson Chi squared test, Student's t-test, ANOVA and Newman-keuls. Result: The aesthetic perceptions among the professionals are similar, and they observe more subtle changes in the aesthetics of the smile than the laypersons observe. The general practitioners and periodontists were similarly sensitive to changes generated in the gingival smile when these reached 1.5 mm, while laypersons o...

“…On the other hand, some authors have observed that subjective perception can greatly influence the judgment of facial and smile features. Several clinical studies [6][7][8] as well as systematic reviews 9 have been performed to define the threshold values of acceptance for different smile characteristics from the point of view of laypeople. The majority of studies have been conducted involving adult observers, with few studies considering the perceptions of children and adolescents.…”

“…However, patients' requests for facial esthetics are not confined to static facial profile, dynamic condition, i.e., smile esthetics is also a main concern. Gummy smile (Pithon et al 2013;Rodríguez-Martínez et al 2014) and dark triangular areas of buccal corridor (Roden-Johnson et al 2005) during smiling are regarded as unattractive, patients wonder whether this kind of unattractive smile would happen or whether already existed unattractive smile could be improved after orthodontic treatment (Maganzini et al 2014;Meyer et al 2014), thus prediction of smiling expressions should be taken into account in orthodontic treatment planning. Blend shape, simulation and performance-driven are the three major computer animation approaches that have been used for generation of facial dynamic expressions (Ersotelos and Dong 2008).…”

Smile esthetics has become increasingly important for orthodontic patients, thus prediction of post-treatment smile is necessary for a perfect treatment plan. In this study, with a combination of three-dimensional craniofacial data from the cone beam computed tomography and color-encoded structured light system, a novel method for smile prediction was proposed based on facial expression transfer, in which dynamic facial expression was interpreted as a matrix of facial depth changes. Data extracted from the pre-treatment smile expression record were applied to the post-treatment static model to realize expression transfer. Therefore smile esthetics of the patient after treatment could be evaluated in pre-treatment planning procedure. The positive and negative mean values of error for prediction accuracy were 0.9 and - 1.1 mm respectively, with the standard deviation of ± 1.5 mm, which is clinically acceptable. Further studies would be conducted to reduce the prediction error from both the static and dynamic sides as well as to explore automatically combined prediction from the two sides.
