Abstract: Provided are a method for producing an acid-reactive glass powder that, when used for a dental glass ionomer cement composition, has good mixing property and a sufficient working time and simultaneously can make the dental glass ionomer cement composition exhibit superior mechanical properties, an acid-reactive glass powder obtainable by the production method, and a dental glass ionomer cement composition comprising the acid-reactive glass powder. More specifically, provided are a method for producing an acid-reactive glass powder characterized in that an acid-reactive glass powder having a range of 2 to 10 µm of a 50% particle size is obtainable by pulverizing a large-particle-size acid-reactive glass powder having a range of 250 to 3000 µm of a 50% particle size in a state where a small-particle-size acid-reactive glass powder having a range of 1 to 5 µm of a 50% particle size coexists; an acid-reactive glass powder obtained by the production method; and a dental glass ionomer cement composition comprising the acid-reactive glass powder.

Abstract: The present invention provides a dental glass ionomer cement composition which can improve the mixing efficiency of a powder and a liquid to an extent where their powder to liquid ratio can be raised in mechanical mixing without reducing a fluoride-release property, and further expresses a high mechanical property. More specifically, the present invention provides a dental glass ionomer cement composition in which a powder and a liquid are separately packaged in a dental capsule, and the powder and the liquid are used by mixing immediately before their use, wherein the composition comprises (a) a hydrophobized acid reactive glass powder, (b) a polyalkene acid, and (c) water, and is not accompanied by a polymerization reaction upon setting.
