Notes:
Calcium sulfate used in this study is newly fabricated to overcome its disadvantages;brittleness, difficult handling properties, rapid resorption and reaction heating. Especially whencalcium sulfate is used in the graft procedure, it is difficult to control the setting time, solubility intoblood and body fluid. To improve the handling properties, Calcium sulfate is mixed withCarboxylmethylcellulose (CMS). The putty type calcium sulfate used in the present study presentedlower values in cementum formation and new bone formation than the control group. This may bedue to use of poor osteoinductive calcium sulfate alone in the defect, limiting new bone formation.In addition, complete resorption of calcium sulfate after 8 weeks presents that addition of polymerfailed to delay the resorption rate of calcium sulfate. Rather, it seemed to disturb the natural healingof the defect when compared with the findings in the control group. But the favorable result ofcalcium sulfate is shown when used with alloplast. The material used in the present study wasdeveloped for easier formability and manipulation avoiding scattering or dissolving of the materialwith blood or body fluid. However, the results reveal that further studies on effect of calciumsulfate with various other bone graft materials and ideal ratios in mixing the two should bedetermined in the future.However, the results reveal that further studies on effect of calcium sulfatewith various other bone graft materials and ideal ratios in mixing the two should be determined inthe future
