Abstract(s)
Objetivos: Avaliar de que forma características faciais assimétricas, desvios do nariz e do queixo, afetam a perceção de atratividade de uma linha média dentária angulada, e se a perceção de atratividade varia entre Leigos e Médicos Dentistas (MD). Foi também analisado se o sexo, faixa etária dos participantes e a principal área de atuação dos Médicos Dentistas são fatores relevantes nessa avaliação.
Métodos: Estudo transversal. Aprovado pela Comissão de Ética da Universidade Fernando Pessoa. A partir de um modelo facial simétrico (MFS), foi criado um rosto assimétrico de aparência natural. Com base nesse modelo facial assimétrico foram criadas 6 imagens, com diferentes direções e graus de inclinação da linha média dentária. 236 Leigos e 242 MD preencheram o questionário online onde classificaram a auto perceção de atratividade das 8 imagens (escala VAS de 0 a 10). Análise de dados com comparações não-paramétricas (IBM SPSS Statistics vs. 27, p<0.05).
Resultados: Existiram diferenças significativas na perceção de atratividade entre os Leigos e MD, para todas as imagens, exceto no MFS. Comparando por sexo do inquirido e por área de atuação do MD, só existiram diferenças significativas no MFS. A perceção de atratividade das imagens, quer para MD quer para Leigos, não diferiu por faixa etária do participante, com exceção das imagens 6 e 8.
Conclusões: Os MD refletem ser mais exigentes/rigorosos em relação a inclinações da linha média dentária, do que os Leigos. O sexo, faixa etária dos participantes e a área de atuação dos MD tiveram impacto na perceção de atratividade.
Goals: Determine if asymmetric facial features, nasal and chin deviations, affect the perception of attractiveness of a dental midline angulation, and if it is consistent among both dentists and lay people. It was also analyzed if factors, such as the sex, age group of the participants and the dentist’s area of operation are relevant in their assessment. Methods: Cross-sectional study. Approved by the Ethics Committee of Fernando Pessoa University. From a symmetrical facial model (SFM), a natural-looking asymmetrical face was created. Based on this asymmetric facial model 6 images were created, with different directions and degrees of inclination of the dental midline. 236 Laypersons and 242 Dentists completed the online questionnaire where they rated the self-perception of attractiveness of the 8 images (VAS scale from 0 to 10). Non-parametric comparisons (IBM SPSS Statistics vs. 27, p<0.05). Results: The results showed a significant difference in the perception of attractiveness between lay people and dentists. This finding was consistent regarding every image, except for the SFM. The factors, sex of the people inquired and dentist´s area of operation, seem only to contribute to a significant difference in the perception when it comes to the SFM. The perceived attractiveness of the images, for Dentists and Laypersons, did not differ by age group of the participant, apart from images 6 and 8. Conclusions: Dentists are more rigorous about dental midline inclinations than Laypersons. The perception of attractiveness was affected by the age group and sex of the participants, and the dentists’ area of operation.
