The present invention provides a dental cement showing excellent storage stability, undergoing little change in paste properties during long-term storage, and having a small solidification risk during long-term storage. The present invention relates to a multi-part dental cement comprising: a first paste comprising an acid group-containing (meth)acrylic polymerizable monomer (a), a polyfunctional (meth)acrylic polymerizable monomer (b) containing no acid group, an oxidizing agent (c-1) of a chemical polymerization initiator, and a filler (d); and a second paste comprising a polyfunctional (meth)acrylic polymerizable monomer (b) containing no acid group, a reducing agent (c-2) of a chemical polymerization initiator, and a filler (e), wherein the filler (d) is treated with a surface treatment agent and has an average particle diameter of 0.01 to 50.0 μm, the surface treatment agent comprises a silane coupling agent (A) represented by the general formula (1) and an organosilazane (B) represented by the general formula (2).
