A new calcium based cement, followed by evaluation of its physical,mechanical,biological and antimicrobial properties,comparing the results with other base restorative material (polycarboxylate cement and biodentine) under the american national standard institute specification number 96 for water based cement.The powder of the new cement was prepared from chicken egg shell while the liquid was polyacrylic acid, more than three thousands four handared formulas were trialed until we reach the appropriate one.The reaction of cement was confirmed by Fourier transform infra-red spectroscopy and Differential Scanning Calorimetry.The new cement was checked for setting time, compressive strength, microhardness, film thickness, solubility, arsenic contents, pH analysis, antibacterial properties and biocompatibilityIn conclusion the prepared cement exhibits better physical and mechanical properties than polycarboxylate cement and accepted with american national standard institute specification number 96 for water based cement. The cement exhibited antimicrobial properties better than polycarboxylate cement and biodentine material.
