ABSTRACT
0.05), nor were the differences between the two experimental groups at 4 and 8 weeks. In comparison with the control group, however, both experimental groups showed superior new bone formation. Although the difference between the two experimental groups was not statistically significant, a tendency for superior new bone formation was detected with the combination of particulate dentin, plaster of Paris, and alginate. Furthermore, more fusion of woven bone and bony trabeculae formation occurred in this group, suggesting that oligosaccharides play a role in the formation and maturation of new bone. In conclusion, the treatment of bone defects by grafting with a mixture of particulate dentin and plaster of Paris alone or with alginate significantly improved the formation of new bone, both quantitatively and qualitatively. The oligosaccharide treatment appeared to improve the formation of new bone quantitatively and qualitatively.
