Effect of glass-ionomer base on composite resin hardness.
The effect of the glass-mm, and 3 mm thicknesses were placed over glass-ionomer bases, and the microhardness of the external surface was compared with that of controls without a base. A significant reduction in surface hardness (p less than 0.05) was determined only for the 1-mm test specimens.
