Rapid replacement of bone by bone filling material in the region lacking bone is quite desirable. Biocompatible pH value and bone filling material composition are necessary. Easy to handle bone filling material is needed. Therefore, in the present study, the relationships among various ratios of powder to chitosan sol and setting tune, pH value, compressive strength and dissolution of the elements were observed.
The results were as follows:
1. An increase in the ratio of powder to chitosan sol resulted in a shortened setting time.
2. An increase in the ratio of powder to chitosan sol resulted in a higher pH value.
3. Compressive strength was influenced by the ratio of powder to chitosan sol.
4. By increasing the ratio of powder to chitosan sol, the dissolution of calcium and silicon increased.
5. These findings indicated that a ratio of powder to chitosan sol of 0.67/2.2 by weight eras optimum for preparation of bone filling material.
