Abstract:
To investigate the influence of mixing ratios on the hardness,wear resistance and compressive strength of the cements clinically used,Zinc Oxide Eugenol cement,Glass ionomer cements,Zinc Phosphate Cement,and Dual-curing composite cement were mixed at different ratios separately,then made into test pieces.Vickers hardness,wear resistance and compressive strength of these test pieces were measured by related machines.The results showed that vickers hardness,wear resistance and compressive strength of Zinc Oxide Eugenol cement,Glass ionomer cements and Zinc Phosphate Cement reduced with the decrease of powder/liquid ratios.As to Dual-curing composite cement,Vickers hardness,wear resistance and compressive strength decreased with the difference between A/B ratio and 1∶1 increase.Conclusively,mixing ratios could influence the mechanical proprieties of the cements clinical used,so the use of cements should be under the instructions of the product.
