<p>A dental restorative composition comprising: (A) polymerizable monomer(s) having at least one phosphorus-containing acidic moiety and at least one ethylenically unsaturated group; (B) polymerizable monomer(s) having a molecular weight of 100-250, at least one hydroxyl group, and at least one ethylenically unsaturated group; (C) polymerizable monomer(s) having a molecular weight of 270-900, at least two ethylenically unsaturated groups and no acidic functional group; (D) photo-initiator(s); and (E) filler(s) each having a mean particle size of more than 0.005 microns and less than 70 microns. The weight ratio of (A+B) : (C) ranges from 30:70 to 90:10, the concentration of (A) is 10-50wt.%, the concentration of (B) is 15-60wt.%, and the composition has a shear bond strength of at least 10MPa to both dentin and enamel.</p> |
