Notes:
This study compared the electrical conductivities, pH and leached ion (F−, Ca, Al, Si) concentrations in supernatant liquids obtained from four glassionomer cements, a buffered ionomer cement, a polycarboxylate cement and a zinc phosphate cement, at three different levels of settings. The result indicated that the measured parameters are highest for the unset condition of cements and decreases as the set condition is approached, except for pH, which shows the opposite trend. Two pulp sensitive glassionomer cements, Chem Bond and Ketac Cem showed high Ca : F ratios as well as high Ca and F concentrations. Further, it is suggested that the cytotoxicity of leached F−, Si, Al and Zn at high concentration and at low pH may induce sensitivity in tooth structure.
