Objetivos: Avaliar como a proporção do tamanho dos dentes ântero-superiores alteram a perceção da atratividade do sorriso por Leigos e Médicos Dentistas (MD) de diferentes países, grupos etários, áreas de especialidade e por género.
Métodos: Estudo observacional transversal, aprovado pela Comissão de Ética da Universidade Fernando Pessoa. A partir de um modelo facial simétrico (MFS) desenvolveram-se 6 imagens com diferentes proporções dentarias do sector anterior. Amostra de conveniência com participantes Leigos e MD de França, Itália e Portugal, que preencheram um questionário online onde classificaram a auto perceção de atratividade das 6 imagens (escala VAS: 0 (mínimo) -10 (máximo)). Análise de dados com comparações não-paramétricas (IBM© SPSS® Statistics vs. 28.0), α=0.05.
Resultados: Os participantes Portugueses (204Leigos/ 195MD), Italianos (204Leigos/ 210MD) e Franceses (214Leigos/ 199MD). Detetaram-se níveis de atratividade significativamente mais elevadas percecionadas por Leigos do que MD em França nas imagens com proporções 70%, 75%, 85% e 90% e em Portugal nas imagens com proporções de 70%, 80%, 85%, 90% e proporções douradas. Não houve diferença significativa entre os MD ligados área de atuação estética e os demais. Detetaram-se diferenças significativas por género nos MD Italianos e Leigos Portugueses. Participantes mais velhos percecionam maior atratividade.
Conclusões: Todos os grupos preferiram o sorriso com os dentes superiores anteriores com proporção dourada e consideraram a imagem com proporção dentaria de 70% como sendo o sorriso menos estético. A área de atuação dos MD não influenciou a perceção, mas o género, idade e nacionalidade são fatores que influenciam a perceção estética.
Goals: To evaluate how the proportion of the size of anterosuperior teeth alters the perception of smile attractiveness by lay and MD dentists from different countries, age groups, specialty areas and by gender. Methods: Cross-sectional observational study, approved by the Ethics Committee of Fernando Pessoa University. From a symmetrical facial model (MFS) 6 images with different tooth proportions of the anterior sector were developed. Convenience sample with laymen and MD participants from France, Italy and Portugal, who completed an online questionnaire where they rated the self-perception of attractiveness of the 6 images (VAS scale: 0 (minimum) -10 (maximum)). Data analysis with non-parametric comparisons (IBM© SPSS® Statistics vs. 28.0), α=0.05. Results: The Portuguese (204 Layman/ 195MD), Italian (204 Laymen/ 210MD) and French (214 Laymen/ 199MD) participants. Significantly higher levels of attractiveness perceived by Laymen than MD were detected in France in the images with 70%, 75%, 85% and 90% proportions and in Portugal in the images with 70%, 80%, 85%, 90% and golden proportions. There was no significant difference between the MDs linked to the aesthetic area and the others. Significant gender differences were detected in Italian and Portuguese MDs. Older participants perceived greater attractiveness. Conclusions: All groups preferred the smile with the upper anterior teeth with golden proportion and considered the image with 70% tooth proportion as the least aesthetic smile. The area of practice of MDs did not influence perception, but gender, age and nationality are factors that influence aesthetic perception.
