| Research Abstract |
Three dimensional pubic bone images, synthesized with 3D scanner and reconstructed from multi-slice CT images, were analyzed to quantify any age-dependent morphological changes of the symphyseal faces. Average values of absolute mean curvatures of pubic symphyseal surfaces under 30 years old were higher than those of older individuals, of which the values were approximately constant. The ratio of the concave areas increased gradually with progressing age classes. In the prinsipal component analysis performed on the homology models of the pubic symphyseal faces, some components specific to each age class were detected. Furthermore, among the specimens of under 35 years old, a few age-correlated components were also identified.
