Studies of Chitin and Chitosan

Part 3． Relation between Setting Time and pH Value of a Chitosan Bonded Bone Filling Material and Volume of CaO and CaSiO₃

Abstract

Bone is composed of calcium, phosphorous, magnesium, and silicon. Therefore, it is most desirable that bone filling material include these elements. It is possible to replace bone filling material for bones. Furthermore, other properties must be regarded as essential, including setting time and pH value.
In the present study, the relationship of various amounts of added CaO and CaSiO₃ to the setting time and pH value were observed. The results were as follows:Increasing CaO and CaSiO₃ volume resulted in shortened setting time. Increasing CaO and CaSiO₃ volume resulted in a higher pH value. The findings indicated that C 4560 is optimum for preparation of bone filling material.
