Outline of Final Research Achievements

Our study examined the mechanical properties of the adult sagittal suture compared with surrounding parietal bones using bending tests. The results suggest that the bending strength of the adult sagittal suture is significantly lower than that of surrounding parietal bones. In female samples, age had significant positive correlations with bending strength at the middle suture sites. The bending strength is significantly higher in male samples than in female samples at the middle suture sites.
Our study also investigated the mechanical properties of the infant skull. The mechanical properties are likely to increase in almost direct proportion to age. However, the number of infant samples was less than expected; sufficient research could not be conducted.
