  An object of the present invention is to provide a paste-type cement composition which while retaining adhesion to tooth substance, biocompatibility, surface curability and fluorine sustained-releasability which are the characteristics derived from the conventional glass ionomer cement, reduces water sensitivity which is shortcoming of the conventional glass ionomer cement, enables simple mixing operation, does not adversely affect on the various properties of a cured cement depending on a difference in operators or a skill degree, and can afford various stable properties. There is provided a two paste-type glass ionomer cement comprising a resin-based paste containing a hydrophobic polymerizable monomer and a polymer of acidic group-containing polymerizable monomers which are insoluble to each other, and a water-based paste containing a hydrophilic polymerizable monomer and water which are soluble to each other, in which an acid reactive filler is contained in at least one of pastes.
