| ABSTRACT Objective: This study evaluated compressive strength and setting time of some types of calcium silicate-based materials modified with chicken eggshell powder (CESP). Material And Methods: The samples were classified into eight major categories, including Group 1 (non-modified glass ionomer cement (GIC) as a control group), Group 2 (1 wt.% eggshell incorporated GIC powder), Group 3 (3 wt.% eggshell incorporated GIC powder), Group 4 (5 wt.% eggshell incorporated GIC powder), Group 5 (non-modified biodentine (BD) as a control group), Group 6 (1 wt.% eggshell incorporated (BD) powder) Group 7 (3 wt.% eggshell incorporated (BD) powder) and Group 8 (5 wt.% eggshell incorporated (BD) powder). Results: (group 2), (group 6) exhibited the highest statistically significant compressive strength means values, while (group 4), (group 8) exhibited the lowest statistically significant setting time means values, Conclusion: Addition of CESP to GIC and BD can increase compressive strength and decrease setting time of materials. | ||||
