Resumo: | The objective was to evaluate the effect of the facial type on the perceptions of varying degrees of deviation from the midline by laypeople. The face image of two mesofacial individuals (male and female) was manipulated in the photoshop program in order to produce the other two facial types (brachyfacial and dolichofacial), as well as in each image, midline deviations (1.0 to 4.0 mm). The photographs were taken with a canon xti camera, with a macro lens, obeying the same distance for both participants, with natural head position. The images generated were evaluated by laypeople, who constituted the universe of the sample. The sample corresponded to 150 participants selected for convenience, using the non-probabilistic sampling technique. The evaluators rated the attraction and acceptance of each photograph. The collected data were tabulated in spreadsheets in the Excel program and evaluated in the Statistica for Windows 7.0 program, with a significance level of 5%. It is observed that the facial type is influenced by the degree of perception of the midline deviation and is influenced by sex and age. The facial type that is most influenced is dolichocephalic and the least affected is brachycephalic. The deviation from the midline in the upper arch was noticeable by laypeople, however a deviation of up to 2 mm from the midline in orthodontic treatment would be acceptable. |

La imagen de la cara de dos individuos mesofaciales (hombre y mujer) se manipuló en el programa de Photoshop para producir los otros dos tipos faciales (braquifacial y dolicofacial), así como en cada imagen, desviaciones de la línea media (1.0 a 4,0 mm). Las fotografías fueron tomadas con una cámara canon xti, con una lente macro, obedeciendo la misma distancia para ambos participantes, con la posición natural de la cabeza. Las imágenes generadas fueron evaluadas por laicos, que constituía el universo de muestra. La muestra correspondió a 150 participantes seleccionados por conveniencia, utilizando la técnica de muestreo no probabilístico. Los evaluadores calificaron la atracción y aceptación de cada fotografía. Los datos recopilados se tabularon en hojas de cálculo en el programa Excel y se evaluaron en el programa Statistica para Windows 7.0, con un nivel de significación del 5%. Se observa que el tipo facial está influenciado por el grado de percepción de la desviación de la línea media y está influenciado por el sexo y la edad. El tipo facial que está más influenciado es dolicocefálico y el menos afectado es braquicefálico. La desviación de la línea media en el arco superior fue notable por los laicos, sin embargo, una desviación de hasta 2 mm de la línea media en el tratamiento de ortodoncia sería aceptable.Objetivou-se avaliar o efeito do tipo facial sobre as percepções de vários graus de desvio da linha média por leigos. A imagem do rosto de dois indivíduos (sexo masculino e feminino) mesofaciais foi manipulada no programa photoshop a fim de produzir os outros dois tipos faciais (braquifacial e dolicofacial), bem como em cada imagem foram simulados desvios de linha média (1,0 a 4,0 mm). As fotografias foram feitas com uma câmera canon xti, com lente macro, obedecendo a mesma distância para os dois participantes, com posição natural da cabeça. As imagens geradas foram avaliadas por leigos, que constituíram o universo da amostra. A amostra correspondeu a 150 participantes selecionados por conveniência, utilizando a técnica de amostragem não probabilística. Os avaliadores classificaram a atração e aceitação de cada fotografia. Os dados coletados foram tabulados em planilhas no programa Excel e avaliados no programa Statistica for Windows 7.0, com nível de significância de 5%. Observa-se que o tipo facial sofre influência no grau de percepção do desvio de linha média e sofre influência de sexo e idade. O tipo facial que mais sofre influência é o dolicocefálico e o que menos sofre influência é o braquicefálico. O desvio de linha média na arcada superior foi perceptível pelos leigos, no entanto seria aceitável um desvio de até 2 mm da linha média no tratamento ortodôntico.
