Abstract:
1. A one-step light-curing dental adhesive composition with improved physical and mechanical properties, and adhesive performance, comprising: (a) 1 to 50 wt % of a prepolymer mixture selected from a group consisting of a mixture of 2,2-bis-[4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]propane (Bis-GMA) of formula 1 with trifunctional methacrylate (Tri-GMA) of formula 2, a mixture of Bis-GMA with tetrafunctional methacrylate (Tetra-GMA) of formula 3 and a mixture of Bis-GMA, Tri-GMA and Tetra-GMA; (b) 1 to 30 wt % of an acidic monomer having carboxylic acid or carboxylic anhydride group in a molecule; (c) 1 to 40 wt % of an adhesive monomer; (d) 1 to 10 wt % of a hydrophilic monomer; (e) 0.1 to 5 wt % of an inorganic filler; (f) 10 to 60 wt % of diluent; (g) 1 to 10 wt % of water; and (h) 1 to 10 wt % of a photoinitiation system, wherein the wt % of all the components are based on the total weight of the composition;
