Effect of Adding Chicken eggs hell powder on Solubility and Bioactivity of Some Types of Calcium Silicate Based MaterialsAbstract:
OBJECTIVE: To evaluate thesolubility and bioactivity of some types of calcium silicate-based materials incorporating chicken eggshell powder (CESP).
MATERIALAND METHODS: The samples were prepared in eight groups, including non-modifiedglass ionomer (NMGIC, n = 10), 1% eggshell incorporated GICs (ESGIC, n = 10),3% eggshell incorporated GICs (ESGIC, n = 10), 5% eggshell incorporated GICs (eggshell GIC, n = 10), non-modified biodentine (NMBD, n = 10),1% eggshell incorporated BD (ESBD, n = 10),3% eggshell incorporated BD,(n= 10) 5% eggshell incorporated BD(n = 10). The solubility of modifiedcalcium silicate-based materials wasevaluated. Thesamples of bioactivity were immersed in simulating body fluid for 1month.Samples were then examined by scanning electron microscopeand energy disperse x ray spectroscopyto examine interfacial layer and Ca/P ratio.
RESULTS: A significantincrease in solubility of modified calcium silicate-based materials was found. Also,the interfacial layer can be seen in GIC and BD groups that modified with ESP. There was a statistically significant difference in the Ca/P ratio among all investigated groups. CONCLUSION: Addition of ESP to GIC and BD can increase solubility of materials and improve the mineral deposition at dentine/ material interface.
