Typically,a 10% polyacrylic acid is applied for 10 seconds to the cavity preparation;it is then rinsed off and the preparation is lightly dried,not totally desiccated.The glass ionomer cement (GIC)is applied to the clean surface and will bond to the calcium.On dentin,phosphoric acid not only removes the smear layer but it also removes the mineral from the surface of the dentin,exposing the collagen matrix.This is not good for the glass ionomers because they chemically bond to the calcium on the surface of the dentin,exposing the collagen matrix.If the surface calcium is removed from the dentin,then the glass ionomer will not bond to the collagen matrix.
