Abstract: Curable compositions comprising degradable macromonomers having one or more terminal acrylate or methacrylate functionality, a curing composition, and optionally one or more polymerizable acrylate or methacrylate comonomers. Degradable macromonomers are manufactured from cyclic monomers with compounds having acrylate or methacrylate functionality. Depending on their use, the degradable macromonomer compositions further comprise one or more organic or inorganic fillers, including a calcium-based compound and/or a radiopacity-imparting agent. The compositions are particularly suitable for root canal sealants, implants, and pulp capping materials.

Abstract: Curable compositions comprising degradable macromonomers having one or more terminal acrylate or methacrylate functionality, a curing composition, a filler composition comprising bioactive particles of bioactive glass, bioactive glass-ceramics, calcium phosphates, calcium apatites, or mixtures thereof and optionally one or more polymerizable acrylate or methacrylate comonomers. Degradable macromonomers are manufactured from cyclic monomers with compounds having acrylate or methacrylate functionality. Depending on their use, the degradable macromonomer compositions further comprise one or more organic or inorganic fillers, including a calcium-based compound and/or a radiopacity-imparting agent. The compositions are particularly suitable for root canal sealants, implants, bone cements, and pulp capping materials.

Abstract: A polymerizable dental composition, comprising a polymerizable resin composition; and a filler composition comprising a bound, nanostructured colloidal silica

Abstract: A curable dental restorative composition having a curable, ethylenically unsaturated component, preferably a hydrophilic, methacrylate-containing monomer or oligomer component, a calcium silicate cement component, and a non-water curing component. Water and/or fillers may optionally be present. The use of curable monomers or oligomers as part of the hardening agent for the cement component results in improved setting time and physical properties in the cured product. Water and/or fillers may optionally be present.

Abstract: A gel composition for use in etching the surfaces of teeth in preparation for prophylaxis, repair, or restoration, comprising an aqueous solution of an effective quantity of an acid; and a colloidal silica sol, wherein the silica portion of the sol comprises from about 3 to about 20 weight percent of the total etchant composition.
