Abstract(s)
Introdução: O conceito de estética e a sua avaliação pode não ser semelhante entre pacientes e Médicos dentistas (MD), pois os últimos têm formação diferenciada para a avaliação estética do sorriso. Podemos dizer que a avaliação estética é difícil de quantificar e é influenciada por vários fatores, principalmente os princípios da estética e as observações de grupos considerados esteticamente privilegiados.
Objetivo: O objetivo deste estudo foi avaliar o efeito da angulação mésio-distal dos incisivos centrais superiores (ICS) na perceção da atratividade do sorriso em Leigos e Médicos Dentistas de Portugal, França e Itália. Foi também analisado se o sexo, faixa etária, países dos participantes e a área de atuação principal dos médicos dentistas são fatores relevantes nessa avaliação.
Materiais e Métodos: Foram utilizadas imagens do sorriso alteradas digitalmente para produzir 7 imagens com alterações diferentes na inclinação dos incisivos centrais superiores no sentido mésio-distal. Foi pedido aos participantes para classificar a auto perceção de atratividade de imagens, usando a escala virtual analógica de 0-10 (0 - “nada atraente” /10 - “muito atraente”).
A análise estatística dos resultados foi realizada recorrendo ao IBM© SPSS® Statistics vs.28.0 através de testes não paramétricos (α=0,05).
Resultados: Os resultados mostraram uma diferença significativa na perceção de atratividade entre Leigos e MD, onde à medida que o grau de angulação mésio-distal dos ICS aumentava as imagens foram classificadas como menos atraentes. Foram preferidas as inclinações mesiais no caso de pequenas angulações e as inclinações distais no caso de grandes angulações. Os MD ligados à estética foram mais críticos em relação aos não ligados à estética. O sexo, idade e o país de origem afetaram a perceção de atratividade.
Conclusões: Os MD são mais rigorosos (atratividade inferior) quanto às angulações mésiodistais dos ICS do que os Leigos. A perceção de atratividade foi afetada pela faixa etária, sexo, país dos participantes e área de atuação do dentista.
Introduction: The concept of aesthetics may not be equivalent between patients and dentists (D) since the latter have differentiated training in the aesthetic evaluation of smiles. We can say that the aesthetic evaluation is difficult to quantify and is influenced by several factors, especially the principles of aesthetics and the observations of groups considered aesthetically privileged. Goals: The aim of this study was to evaluate whether the effect of mesio-distal angulation of maxillary central incisors (SCI) affects the perception of smile attractiveness among laypersons and dentists in Portugal, France and Italy. It was also analysed whether gender, age range, participants' countries and dentists' main area of practice are relevant factors in this evaluation. Methods: Digitally altered smile images were used to produce 7 images with different changes in the inclination of maxillary central incisors in the mesio-distal direction. The self-perception of attractiveness of the images was counted by the participants using a virtual analogue scale of 0-10, (0 -"not at all attractive" and 10 - "very attractive"). Statistical analysis of the results was performed using IBM SPSS Statistics vs.28.0 using non-parametric tests (α=0.05). Results: The results showed a significant difference in perceived attractiveness between laypersons and MD, whereas the degree of mesio-distal angulation of the SCI increased the images were rated as less attractive. Mesial inclinations were preferred in the case of small angulations and distal inclinations in the case of large angulations. Aesthetics-related MDs were more critical than non-aesthetics-related MDs. Gender, age and different countries affected the perception of attractiveness. Conclusions: MDs are stricter (lower attractiveness) about the mesio-distal angulations of maxillary central incisors than laypersons. The perception of attractiveness was affected by the age group, gender, country and practice area of the dentist.
