Stable tooth bleaching gels with a high concentration of peroxide are disclosed. The present invention also provides a method for treating one or more teeth. The method includes steps of applying a therapeutically effective amount of a tooth bleaching gel with a high concentration of peroxide to one or more teeth, leaving the gel in contact with the one or more teeth such that the gel may whiten the tooth or teeth.

Stable tooth whitening gel

A thixotropic, smooth-flowing liquid, bulk-water-free dentifrice gel/paste that contains a stable mixture of at least one of amylopectin containing discrete solid particles and modified amylopectin containing discrete solid particles, uniformly suspended in and wetted by an inert essentially anhydrous organic hydroxylated liquid matrix material, and which dentifrice gel/paste is characterized by a high surface sheen. Preferably, the modified homopolysaccharide discrete particles contain esterified amylopectin and/or esterified amylose. The dentifrice gel/paste can be used as a toothpaste, a bleaching gel and a brushing gel.

In the process of implanting a metal dental prosthesis into or on the alveolar bone, to provide anchorage or stabilization either to a tooth or to another prosthesis, which involves surgical exposure of the alveolar bone, providing means for (a) fixing a metal implant in the alveolar bone, and (b) fixing the metal implant to either a tooth or to the other prosthesis, and closing the exposure of the alveolar bone, the improvement which comprises including in respect to such means the step of applying to one or more portions of the implant or to the locus of the implant in the alveolar bone, a primary coating comprising a crosslinked resin that (i) optionally contains leachable fluoride and (ii) is biocompatible with osseous and non-osseous tissue, to effect direct bonding of the implant to the tooth or to the prosthesis, or to bone or to non-osseous tissue or a combination of them. A treated prosthetic is also described.

An adhesive composition useful for restoration comprising a finely-divided reinforcing filler, a polymerizable matrix material, a bonding agent, a coupling agent, and a thermal initiator.

Restorative dental adhesive composition

Two-part dental cement systems based on glass ionomers which are curable on exposure to light. The dental cement systems comprise a two-part blend of sodium N(p-tolyl)glycine-glycidyl methacrylate (Na NTG-GMA) and pyromellitic dianhydride-methyl methacrylate (PMDM) resins and glass ionomers.

Light-curable ionomer dental cement

A toothpaste characterized by a low abrasion, non-reactive base formulation. The toothpaste has a near neutral or neutral pH. The toothpaste contains a concentration of citric acid, sodium or potassium citrate, papain, and fine-particle-sized aluminum oxide, in particular portions which effectively clean away plaque, mucin and tartar.

Toothpaste having low abrasion

A bonding adhesive for dentistry and a method for preparing the surface of dentin, enamel, or other natural or industrial substrates containing or capable of binding metallic ions, for adhesion of composite materials or resins. First, an aqueous solution of phosphoric acid or a mixture of phosphoric and nitric acids along with aluminum oxalate, or phosphoric acid alone, is applied to the surface. Second, a solution comprising a solvent and at least one compound selected from the group consisting of (1) N-phenylglycine in a mixture with the alkali metal salt of N-phenylglycine, (2) a mixture of the adduct of the alkali salts N(p-tolyl)glycine and glycidyl methacrylate, with the mixture N(p-tolyl)glycine and glycidyl methacrylate (3) the addition reaction product of the alkali metal salt of N-phenylglycine and glycidyl methacrylate, and N-phenylglycine, N(p-tolyl) glycine, N-phenylalanine, sarkosine, N-laurylsarkosine, glycine, N,N-dimethylglycine, 3(N-phenyl) amino propionic acid, 3(N-p-tolyl) amino propionic acid, omega-amino fatty acids, N-substituted-omega-amino fatty acids, the addition reaction product of N-phenyl glycine and glycidyl reagents, the reaction product of N(substituted phenyl) glycine and glycidyl reagents, and other amino acids; is applied to the surface. Third, a solution of PMDM is applied to the surface.

Dental compositions incorporating glass ionomers

A filled-resin composition useful for porcelain repair and as a dental composite and therefore made up of non-toxic materials and a method for repairing porcelain or teeth. The composition comprises a methacrylate functional resin usable in dental composites, powdered filler-colorant therein, at least one photoinitiator for the resin in an amount sufficient to initiate polymerization and complete it in depth within about half a minute when exposed to a visible-light output of at least 5,000 foot candles, the photoinitiator being an exciplex of (1) an carbocyclic ketone or acetal and (2) either ethyl-4-dimethyl amino benzoate or ethyl-2-dimethyl amino benzoate, and at least one accelerator-free peroxide curing agent for the resin in an effective amount for completing polymerization within about one-half hour of any portion of the resin not receiving sufficient light to effectuate complete cure before then. The method comprises mixing the components together under ordinary indoor lighting conditions, emplacing the mixture within a few minutes of the mixing, and curing at least a substantial portion of the emplaced mixture in situ for one half-minute under intense visual-light illumintion of at least 5000 foot-candles. Any resin then uncured by light is cured within the next half hour by the peroxide curing agent.
