Abstract:The interaction of three commercial zinc polycarboxylate cements with tooth structure was investigated by using infrared spectroscopic techniques. The obtained data revealed that the cements interact with enamel and ionic bonds are formed between calcium ions in enamel and carboxyl groups in polycarboxylic acid. The interaction depends on the percentages of ZnO content in the powders and of carboxylic acid in the liquids of these cements. The results provided some evidence that the cements also may interact with dentin but to a lesser extent than with enamel. The interaction of the cements with the metals copper and nickel or with Cr2O3, was also studied.
