Abstract
There is provided a highly functional one-step light-curing dental adhesive composition i) based on a multifunctional prepolymer mixture of 2,2-bis-[4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]propane ('Bis-GMA') and a multifunctional prepolymer formed by substitiuting hydrogen atoms of hydroxyl groups present in Bis-GMA molecules with methacrylate groups, in which the Bis-GMA is used as a base prepolymer of conventional dental adhesive compositions; and ii) comprising and acidic monomer for removing a portion of smear layer, which is allowed to be bonded without separate treatment of acid etchant, an adhesive monomer having both hydrophobic and hydrophilic properties, a hydrophilic monomer which is allowed to be bonded in the present of moisture, an inorganic filler for improving mechanical properties, diluent, water for demineralization, a photoinitiation system and other additives.
