Objetivos: Esta investigação visa analisar e comparar a perceção de Médicos Dentistas Especialistas em Ortodontia, Médicos Dentistas Generalistas e indivíduos leigos quanto à assimetria facial, particularmente em relação ao desvio da mandíbula (laterognatia) e inclinação do plano labial.
Materiais e Métodos: Faces do sexo feminino e masculino construídas no programa Character Creator 4® foram manipuladas para simular 2, 4 e 6 milímetros de laterognatia e 1.5º, 3º e 4.5º de inclinação do plano labial. Posteriormente, foram avaliadas por Ortodontistas, Médicos Dentistas Generalistas e leigos através de um questionário online. Solicitou-se aos participantes que avaliassem cada face numa escala numérica de 0 a 10 e as ordenassem por ordem de preferência estética. Os dados foram analisados no programa IBM SPSS Statistics®, através de técnicas de análise estatística descritiva e inferencial com um nível de significância de 5% (p<0.05).
Resultados: Na maioria das faces, verificou-se uma diminuição progressiva na avaliação estética à medida que o grau de assimetria aumentou. Os Ortodontistas atribuíram pontuações significativamente superiores às faces feminina (p<0.001) e masculina (p=0.013) simétricas em comparação com os leigos. Nas faces com 1.5º de inclinação do plano labial, os leigos atribuíram pontuações significativamente inferiores às dos Ortodontistas nas faces feminina (p=0.006) e masculina (p=0.002). Os três grupos, de um modo geral, foram unânimes na perceção da inclinação do plano labial a partir dos 3º.
Conclusões: Os Ortodontistas possuem uma capacidade superior no reconhecimento da simetria facial relativamente aos leigos. No entanto, os leigos percecionam a laterognatia mais precocemente que os Ortodontistas e Médicos Dentistas Generalistas. Para os três grupos estudados, a inclinação do plano labial e a laterognatia tiveram um diferente impacto estético. Constatou-se que o sexo e o tempo de experiência profissional não tiveram influência significativa na perceção das assimetrias faciais analisadas.
Aims: This study aims to analyze and compare the perception of Orthodontists, General Dentists and laypeople regarding facial asymmetry, particularly in relation to mandibular deviation (laterognathia) and lip-line canting. Materials and Methods: Female and male faces created using the Character Creator 4® software were manipulated to simulate 2, 4 and 6 millimeters of laterognathia and 1.5º, 3º, and 4.5º of lip-line canting. These faces were evaluated by Orthodontists, General Dentists and laypersons through an online questionnaire. Participants were asked to rate each face on a numerical scale ranging from 0 to 10 and to rank them according to their aesthetic preference. The data were analyzed using IBM SPSS Statistics®, employing both descriptive and inferential statistical methods with a significance level of 5% (p<0.05). Results: In general, there was a progressive decrease in aesthetics ratings as the degree of asymmetry increased. Orthodontists gave significantly higher scores to both symmetrical female (p<0.001) and male (p=0.013) faces compared to laypeople. In faces with a 1.5º lip-line canting, laypeople rated both the female (p=0.006) and the male (p=0.002) faces significantly lower than Orthodontists. The three groups were generally unanimous in perceiving lip-line canting from 3º onwards. Conclusion: Orthodontists demonstrated a superior ability to recognize facial symmetry compared to laypeople. However, laypeople detected laterognathia earlier than Orthodontists and General Dentists. For all three groups, lip-line canting and laterognathia had a different aesthetic impact. It was also found that neither gender nor professional experience had a significant influence on the perception of the facial asymmetry types analyzed.
