An antibacterial bonding compositions for dental use, which comprises (A) an antibacterial primer that comprises an antibacterial polymerizable monomer having an ethylenic unsaturated group and at least one or more cationic groups selected from the group consisting of ammonium bases, pyridinium bases and phosphonium bases, and a volatile solvent, and (B) an adhesive composition comprising an acid group having polymerizable monomer, a polymerizable monomer, and a polymerization initiator; and an adhesive compositions for dental use, which comprises (P) an adhesive primer comprising an acid group having polymerizable monomer, a hydrophilic polymerizable monomer, and water, and (Q) a bonding agent comprising a polymerizable monomer, and an acylphosphine oxide compound and an &agr;-diketone compound both serving as a polymerization initiator. The bonding compositions can inhibit the growth of cariogenic bacteria in the bonded area of a tooth as restored with a restorative dental material in dental treatment thereby preventing secondary caries and odontitis around that area, and can enhance the bonding strength, especially the bonding durability of the restorative dental material to the tooth.
