RESUMEN
OBJECTIVE: To evaluate the influence of anteroposterior position of the soft tissue on facial attractiveness in black people, and compare the perception of aesthetics and satisfaction between orthodontists and black laypersons. METHODS: The sample was composed of 69 orthodontists and 69 laypersons of black ethnicity (n=138). Facial profile photographs of two black volunteers, a man and a woman, were digitally manipulated to change the position of the lips and chin, by making gradual changes of 4mm in relation to the true vertical line, simulating advance or retrusion of the soft tissues by -2, -6, -10, +2, +6, +10mm, totalling six images per sex. The photographs were classified by the research participants using a visual analogue scale (VAS), from 0 (unpleasant) to 100 (pleasant). The results were analyzed by generalized linear model and by the Fisher's exact test, considering the level of significance of 5%. RESULTS: The orthodontists and black laypersons considered straight profiles the most pleasant. The two groups classified the male profile as being more unpleasant in comparison with the female facial profile, which was concave. When evaluating all the images together, the image most indicated as being the most pleasant, once again, was the one with the straight profile, for both sexes. CONCLUSION: The influence of orthodontists' and laypersons' aesthetic perception on evaluating the facial profile of blacks was similar. The straight profile was classified as the most pleasant and the concave, as the most unpleasant.

RESUMO Objetivo: Avaliar a influência do posicionamento anteroposterior dos tecidos moles na atratividade facial de indivíduos negros, e comparar sua agradabilidade entre ortodontistas e leigos. Métodos: A amostra foi composta por 138 avaliadores, 69 ortodontistas e 69 indivíduos leigos da raça negra. Fotografias de perfil de dois pacientes negros, um homem e uma mulher, foram modificadas quanto ao posicionamento dos lábios e do mento, deslocados digitalmente em incrementos de 4 mm em relação a uma linha vertical verdadeira, simulando avanços e recuos dos tecidos moles de -2, -6, -10, +2, +6, +10 mm, totalizando seis imagens por sexo, classificadas pelos participantes da pesquisa usando uma escala visual analógica (EVA) de 0 (desagradável) a 100 (agradável). Os resultados foram analisados por meio de modelos lineares generalizados, considerando-se que todos os observadores avaliaram todas as imagens. A análise das escolhas das imagens consideradas mais agradáveis ou mais desagradáveis foi realizada pelo teste exato de Fisher, com um nível de significância de 5%. Resultados: Os ortodontistas e leigos consideraram mais agradáveis as alterações que se aproximavam do perfil reto. Nas imagens em que havia birretrusão facial, os dois grupos classificaram como mais desagradável o perfil do homem do que o perfil da mulher. Ao avaliar todas as imagens juntas, a imagem mais indicada como a mais agradável foi, novamente, a com perfil reto, para os dois sexos. Conclusão: A influência da percepção estética dos ortodontistas e leigos na avaliação do perfil facial de negros foi semelhante, sendo o perfil reto classificado como o mais agradável e o côncavo, o mais desagradável.
