[Bonding of glass-ionomer cements to tooth hard tissues under various experimental conditions].
In this study the enamel- and dentin-bonding properties of two glass-ionomer cements (ChemFil-II and Ketac-Bond) were evaluated under various test conditions in vitro. The tests showed the following results: 1. ChemFil-II exhibits a significantly stronger bond to the hard tooth substances than Ketac-Bond in the short term test (the samples were stored 2 days in synthetic saliva). The stability of the bond made with ChemFil-II, however, proves in the long term test (the samples were stored 150 days in synthetic saliva) to be less than that made with Ketac-Bond. 2. Acid-conditioning of the enamel does not statistically effect a change in the stability of the bond to any significant degree. Corresponding conditioning of the dentin, on the other hand, causes a definite reduction of the bond to be obtained. 3. Deviations from the powder-liquid mixing ratio recommended by the manufacturer result in a statistically significant reduction in the bond stability, whether these involve an increase in the amount of powder or rather a decrease.
