Abstract: The mandibles found in different regions of the planet present
considerable morphological differences, propounding questions about the
morphological changes and characteristics of the human’s mandibles. The
racial plurality and the consequent miscegenation of the Brazilian
population must to offer morphological changes. Thirteen measurements
were used in this research to analyze and compared the morphological
characteristics of the one hundred Brazilian human mandibles, with
mandible’s dimensions of the Australians, Asiatic, Europeans, and
Africans. The significant and highly significant differences in means
values were calculated by testt student, p < 0.05 andp < 0.01,
respectively. Were observed highly expressive differences in the
analyzed dimensions, what reflect the presence of the anatomic
variations in the mandible’s morphology of the different populations.
The Europeans mandibles show mandibular ramus narrower than when
compared with the Brazilians, while the Asiatic show larger mandibles,
however the height of the mandibular symphysis is smaller. Several
aspects can determine the morphological differences met, like
adaptations of the estomatognáthic system came of the bony plasticity
promoted by the diet’s consistency or aforesaid caused by the racial
Mandible; Morphology; Morphometry; Brazil.
