AB  - 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.

AB  - This study aimed to investigate the influence of ZrO2, Bi2O3 and SrF2 added as radiopacifying agents (30wt.%) into calcium silicate/hydroxyapatite-based dental cement on its physical and biological properties. Among investigated cements, the mixture containing Bi2O3 had the highest values of elastic modules and toughness, similarly to control – mineral trioxide aggregate (MTA). SEM analysis of all hydrated cements has shown that bioactive calcite and tobermorite phases were formed. Crystal violet assay showed that pure (undiluted) extracts of experimental cements did not affect cell viability, while MTA exhibited an extremely cytotoxic effect on L929 cells. In 1:4 dilutions all experimental mixtures significantly increased cell proliferation potential after 72h in comparison to untreated cells and MTA, which cytotoxic effect diminished with dilutions. Further studies are needed to determine which radiopacifyer has the most desirable properties for adequate dental cement fabrication.
