The present invention provides a multiple part ionomeric cement system comprising an organic composition that is substantially free of added water, and an aqueous composition comprising water. The organic composition contains at least a hydrophilic component and an acid functional compound that is provided as greater than 1.0% weight of the organic composition. The liquid ingredients of the compositions are miscible, both as separate compositions and when mixed together.

[ What is claimed:] [1.] A multiple part ionomeric cement system comprising:a) an organic composition having a liquid ingredient that is free of water, except as is present as a coordination complex in its normal state or that has been taken up from the atmosphere, comprisingi) a hydrophilic component that is miscible in water at a concentration of about 3% by weight or can absorb at least 2 grams of water per hundred grams of polymerii) an acid functional compound having sufficient pendent ionic groups to undergo a setting reaction in the presence of a reactive filler and water that is provided as greater than 1.0% weight of the organic composition,wherein the liquid ingredients of said organic composition form a miscible solution, andb) an aqueous composition having a liquid ingredient comprisingi) waterwherein the liquid ingredients of said aqueous composition form a miscible solution, and further provided that at least one of said organic composition and said aqueous composition comprises an acid reactive filler provided that said aqueous composition does not contain both an acid reactive filler and an acid, at least one of said organic composition and said aqueous composition comprises a polymerizable component, at least one of said organic composition and said aqueous composition comprises a polymerization catalyst to initiate polymerization of said polymerizable component, the liquid ingredients of said organic composition and said aqueous composition being miscible when mixed together, and said organic composition and said aqueous composition being free of surfactant.
