relative solubility of four glass ionomer cements

The purpose of this investigation was to determine and compare the relativesolubility of four different types of glass-ionomer cement. A sample size of20 samples [five samples for each cement] was employed in the present study. From the results obtained, it was concluded that the glass cement demonstratedthe least solubility values, followed by anhydrous and visible light curedglass ionomer cements. On the other hand, the conventional glass ionomercement was found to be the most soluble one, also it was found that, there isno significant difference in the solubility values between anhydrous andvisible light cured glass-ionomer cements
