Abstract
A practically non-aqueous dental cement composition is disclosed and the dental cement composition comprises a polymer or co-polymer having an .alpha.,.beta.-unsaturated carboxylic acid as an essential component of a main monomer; and an inorganic powder capable of forming a metal chelate in the presence of water characterized in that the polymer or co-polymer exists as a solution in a polymerizable monomer that can dissolve the polymer or co-polymer. This provides a dental composition which has not only the advantages of the conventional glass ionomer cement but also a higher setting rate and more desirable physical properties of the setting product and is excellent also in durability, by eliminating the disadvantages in the setting rate and physical properties of the set cement.
