Abstract:
A dental composition for bonding restorative material to human tooth dentin, comprisingat least 70 percent by weight of a volatile organic solvent, at least 15 percent by weight of polymerizable acrylate compounds and an effective amount of a photoinitiator, at least two of said polymerizable acrylate compounds being diacrylate compounds, at least one of said diacrylate compounds having a gram molecular weight greater than 200, at least a portion of said polymerizable acrylate compounds are multifunctional polymerizable compounds having at least three acrylate moieties and one phosphate moiety, said polymerizable acrylate compounds being substantially soluble in said solvent and substantially insoluble in water, said composition being adapted to form a polymeric material which bonds dental restorative material to an etched dentin surface of said tooth with a bond strength of at least 12 MPa to form a filled cavity having a seal between said material and said tooth cavity dentin surface to prevent ingress of fluid and bacteria into said filled cavity.
