The aim of this study was to investigate the properties of experimental calcium aluminate (CA) dental cement, synthesized from CaO×Al2O3 and CaCO3. Calcium silicate (Portland cement, PC) served as a control. The elastic modulus and maximum stress obtained using the universal testing machine showed that CA has greater mechanical resistance than the control PC. Scanning electron microscopy (SEM) analysis of cements specimens before and after soaking in phosphate buffer saline showed that hydrated cements exposed crystal particles of calcite and new aluminum containing phases on their surfaces, suggesting their bioactive potential. Biocompatibility of the CA dental cement was evaluated by observing L929 cells morphology using phase-contrast microscopy. Cells treated with CA extract preserved their structural integrity without any changes in cell morphology, but with a slightly inhibited proliferation rate after 24h treatment, while PC induced changes typical for cell death.
