Resumo: | This study aimed to investigate the applicability of mandibular measures for sex estimation in human dry skulls from two Brazilian bone collections. This was a blind diagnostic study with 471 mandibles of 215 females and 256 males. The variables considered were: bigonial-width; bicondylar-width; right/left condylar process width; coronoid width; distance between the mandibular foramina; distance between the mental foramina; distance between the genial spinal foramina and the right/left mandibular foramina; right/left coronoid process height; right and left mandibular ramus height; right/left mandibular thickness; anterior mandibular thickness; maximum width of the right and left mandibular ramus; minimum width of the right and left mandibular ramus; mandibular-length; and the mandibular angle. Discriminant analysis was performed to check for associations concerning sex both for individual and total measurements. The statistical analysis indicated that all variables were found to be significantly associated with sex. When applied to males and females, the stepwise method correctly classified 77.50% and 80.20% of the cases, respectively, with a total percentage of agreement of 78.70%. The left mandibular ramus height (74.80%) and the bigonial width (77.60%) were the variables with the highest agreement rates among males and females, respectively. Equations were generated from the discriminant analysis for each variable and a unique formula for the six variables showed the highest preference for sex. All mandibular measures were statistically different between the sexes, suggesting that the mandible plays an important role in forensic anthropology as a source of quantitative information for sex estimation. |

Este fue un estudio diagnóstico ciego con 471 mandíbulas de 215 mujeres y 256 hombres. Las variables consideradas fueron: bigonial-width; ancho bicondilar; ancho de la apófisis condilar derecha/izquierda; ancho de las coronoides; distancia entre los agujeros mandibulares; distancia entre los agujeros mentonianos; distancia entre los agujeros espinales geniales y los agujeros mandibulares derecho/izquierdo; altura de la apófisis coronoides derecha/izquierda; altura de la rama mandibular derecha/izquierda; espesor mandibular derecho/izquierdo; espesor mandibular anterior; ancho máximo de la rama mandibular derecha/izquierda; ancho mínimo de la rama mandibular derecha/izquierda; longitud mandibular; y el ángulo mandibular. Se realizó un análisis discriminante para verificar las asociaciones con respecto al sexo tanto para las mediciones individuales como para las totales. El análisis estadístico indicó que todas las variables se asociaron significativamente con el sexo. Cuando se aplicó a hombres y mujeres, el método escalonado clasificó correctamente el 77,50% y el 80,20% de los casos, respectivamente, con un porcentaje total de acuerdo del 78,70%. La altura de la rama mandibular izquierda (74,80%) y el ancho bigonial (77,60%) fueron las variables con mayores tasas de concordancia entre hombres y mujeres, respectivamente. Se generaron ecuaciones a partir del análisis discriminante para cada variable y una fórmula única para las seis variables que mostraron la mayor preferencia por el sexo. Todas las medidas mandibulares fueron estadísticamente diferentes entre los sexos, lo que sugiere que la mandíbula juega un papel importante en la antropología forense como fuente de información cuantitativa para la estimación del sexo.Objetivou-se investigar a aplicabilidade de medidas mandibulares para estimativa do sexo em crânios secos humanos de duas coleções osteológicas brasileiras.

As variáveis consideradas foram: largura bigonial; largura bicondilar; largura do processo condilar direito/esquerdo; largura do coronóide; distância entre os forames mandibulares; distância entre os forames mentais; distância entre os forames espinhais geniais e os forames mandibulares direito/esquerdo; altura do processo coronóide direito e esquerdo; altura do ramo mandibular direito/esquerdo; espessura mandibular direita/esquerda; espessura mandibular anterior; largura máxima do ramo mandibular direito/esquerdo; largura mínima do ramo mandibular direito/esquerdo; comprimento mandibular; e o ângulo mandibular. A análise discriminante foi realizada para verificar as associações em relação ao sexo, tanto para as medidas individuais quanto para o total. A análise estatística indicou que todas as variáveis apresentaram associação significativa com o sexo.
