Figures 8–11. Figure 8. Bar chart showing the percentage of area in the defect occupied by granules at 6 and 12 weeks. No significant statistical differences among groups or experimental times could be found. Values are presented as mean ± SD. Figure 9. Bar chart showing the percentage of area in the defect occupied by bone tissue at 6 and 12 weeks. Significant statistical differences were found, as shown: (1) SHA(s) values for 12 weeks differed significantly from other biomaterial groups and control. (2) BHA(s) values for 12 weeks differed significantly from SHA(l). (3) BHA(s) values differed between 6 and 12 weeks. Values are presented as mean ± SD. Figure 10. Bar chart showing the percentage of area in the defect occupied by bone marrow at 6 and 12 weeks. Significant statistical differences were found, as shown: (1) When the marrow area at 6 weeks was compared among biomaterial groups, the BHA(l) values were significantly smaller than the others. (2 and 3) Control values at 6 and 12 weeks differed significantly from biomaterial groups. Values are presented as mean ± SD. Figure 11. X-ray diffraction (XRD) of BHA (left side) and SHA (right side) granules. The sharpness of the XRD peaks demonstrates the similarities in crystallinity of these biomaterials.
