Abstract: A one-component self-etching self-priming dental adhesive composition is disclosed. The composition comprises glycerol phosphate di(meth)acrylate monomer, at least one mono-functional polymerizable monomer having just one ethylenically unsaturated group, at least one multi-functional polymerizable monomer having at least two ethylenically unsaturated groups, at least one aprotic solvent, at least one protic solvent, and at least one polymerization initiator.

Abstract: A method for temporarily widening a gingival sulcus. A composition comprising a polymerizable monomer having at least one ethylenically unsaturated group, a photo polymerization initiator, and a fine inorganic powder is inserted within a gingival sulcus to be widened, and the composition is thereafter irradiated in situ to polymerize the composition. The result is a rubbery material that is easily removable from the widened sulcus.

Abstract: At least one clay, at least one glass filler, and at least one astringent agent are formulated with water into a paste for injection in dental and medical applications. In one embodiment, the paste is used to treat and/or widen a gingival sulcus. The paste is readily rinsed off the surface to which it is applied using water.

Abstract: Thermally re-mendable cross-linked polymeric materials that can be repeatedly mended or repaired by simple thermal treatment. The polymeric materials are made by polymerizing furan monomers and maleimide monomers via the Diels-Alder (DA) reaction wherein the furan monomers have at least three furan moieties and the maleimide monomers have at least three maleimide moieties. The intermonomer linkages that form between the furan and maleimide monomers are thermally reversible and do not require the addition of catalysts, additional monomer or special surface treatments.
