Disclosed in a cement composition comprising an unsaturated carboxylic acid polymer and an alkaline earth metal aluminofluorosilicate glass, wherein the alkaline earth metal aluminofluorosilicate glass comprises (a) 50 to 95% by weight of coarse particles having a spherical shape and an F/Si ratio of at least 0.1 but lower than 0.6 and having a particle size larger than 3 .mu.m but not larger than 50 .mu.m and (b) 5 to 50% by weight of fine particles having an F/Si ratio of 0.6 to 5 and a particle size of up to 3 .mu.m.
This cement composition gives a cured body having a good surface gloss and a high strength, and this cement composition has a good flowability and a good workability. Accordingly, the cement composition is valuable as a dental cement composition.
