Disclosed is a novel glass ionomer type dental cement composition comprising a first component comprising an aqueous solution of polymers made from monomers comprising acrylic acid, and a second, preferably substantially anhydrous, component comprising alkaline glass flux in a medium comprising water soluble/miscible monomers or pre-polymers, of such monomers, having at least one -OH group per molecule. The compositions offer more convenient handling, excellent reproducibility of desired properties of the cured material, improved strength, and extended shelf life.
