The sample was compounded by 60 subjects, being 24 males and 36 females. All of them were Brazilians, leukoderms with natural normal occlusion, presenting four out of the six keys to ANDREWS s occlusion. The natural head position and the true vertical line were used at the moment of the lateral cephalograms and the profile photographs take, these made up the methodology for the study. The Cephalometric soft tissue analysis was performed evaluating the dentoskeletal factors, soft tissue structures, facial lengths, true vertical line projections and the harmony intramandibular, intrajaw and total face. The results demonstrated that the medium values of the studied sample presented differences in relation to the normative values of ARNETT et al. in most of the variables. As facial height when compared, they allowed to conclude that the Americans present larger facial height, straighter facial profile and more prominent nose than the Brazilians, so much in the masculine sex as in the feminine. The masculine sex presents facial height and thickness of the larger soft fabrics than the feminine sex, however, upper lip and inferior less protruded in relation to true vertical line. / Este estudo teve como objetivo aplicar e avaliar a Análise Cefalométrica do Tecido Mole proposta por ARNETT et al. em jovens brasileiros, determinando seus valores médios e comparando com os dos autores. A amostra compôs-se de 60 indivíduos, sendo 24 do sexo masculino e 36 do sexo feminino. Todos brasileiros, leucodermas e portadores de oclusão normal natural, apresentando um mínimo de quatro das seis chaves de oclusão de ANDREWS. A utilização da posição natural da cabeça e da linha vertical verdadeira no momento da obtenção das telerradiografias compuseram a metodologia do trabalho. Avaliaram-se os fatores dentários e os esqueléticos, as espessuras do tecido mole, os comprimentos faciais, as projeções do tecido mole em relação à Linha Vertical Verdadeira e a harmonia intramandibular, a intermaxilar e a facial total. Os resultados demonstraram que os valores médios da amostra estudada apresentaram diferenças em relação aos valores normativos de ARNETT et al. na maioria das variáveis e quando comparados entre si, verificou-se que os americanos apresentaram altura facial maior, perfil facial mais reto e nariz mais proeminente que os brasileiros, tanto para o sexo masculino como para o feminino. O sexo masculino apresentou altura facial e espessura dos tecidos moles maior que o sexo feminino, porem, lábios superior e inferior menos protruídos em relação à Linha Vertical Verdadeira. A
