    • An object of the present invention is to provide a dental composition having excellent adhesive effect and simultaneously not causing microleakage.A dental composition of a first embodiment of the present invention includes (A) an acidic-group containing polymerizable monomer, (B) a polymerizable monomer, (C) a filler comprising poly(meth)acrylate particles, (D) a calcium-containing material including tetracalcium phosphate (TTCP) and dicalcium phosphate (DCP), and (E) a polymerization initiator. The component (A) is contained at 16-70 parts by weight based on a total of 100 parts by weight of (A)+(B). The component (B) is contained at 84-30 parts by weight based on a total of 100 parts by weight of (A)+(B). The component (C) is contained at 0.2-297 parts by weight relative to a total of 100 parts by weight of (A)+(B). The component (D) is contained at 0.2-297 parts by weight relative to a total of 100 parts by weight of (A)+(B).
