Abstract: The present invention relates to a method for reducing or eliminating loss of minerals from the enamel and dental hypersensitivity against temperature changes, in particular when caused by the bleaching of teeth with products containing hydrogen peroxide or other oxidizing agents. After the bleaching process the teeth are treated with a calcium hydroxide containing solution, and subsequently the teeth are treated with a fluoride solution.

Abstract: A process for treating a metallic implant consisting essentially of treating the metallic implant with a solution of hydrofluoric acid, which solution has a pH between 1.6 and 3.0.

Abstract: A titanium implant having increased retention after insertion in bone. The implant comprises phosphate groups bound to the metallic titanium. A process for preparing said titanium implant, wherein an implant is prepared in a per se known manner, and then the oxide layer formed on the surface of the implant, is removed to expose the metallic titanium. The exposed implant is then treated with a phosphate solution in the absence of oxygen, to bond phosphate groups to the titanium surface, said groups securing a firm attachment of the implant to the bone into which it is inserted.

Abstract: An oral hygiene preparation for inhibiting halitosis, in the form of a tablet or a powder forming a mouthwash upon dissolution in water, which contains copper(ll)gluconate and a disintegrating agent selected from sodium and calcium bicarbonate.

Abstract: Oral composition for inhibiting oral malodor, containing an antibacterial agent and a zinc compound, in the form of a mouthwash containing 0.005-0.05% w/v of an antibacterial agent selected from bis-guanides and quaternary ammonium compounds, and 0.05-0.5% w/v of zinc acetate.

Abstract: Metallic surgical implant materials having improved strength of connection with bone are produced when the implants are treated prior to implantation with an aqueous solution of sodium fluoride.

Abstract: Dentifrice comprising a liquid silicone oil and a fat-soluble antibacterial agent dissolved therein either directly or indirectly after dissolution of the antibacterial agent in an organic solvent. The dentifrice is useful for protection of teeth against plaque formation due to a slow release of the antibacterial agent into the saliva.

Abstract: The present invention relates to a dentifrice composition having an improved anti-plaque effect. The composition comprises stanous pyrophosphate as an anti-plaque agent, the activity of which can be increased according to the invention by including a water-soluble monofluorophosphate salt in the composition.

Abstract: Aqueous dental preparation containing fluoride ions and having a pH of maximum about 2. The preparation is suitably based on aqueous hydrofluoric acid (HF), particularly with a concentration of 0.5-5% (w/v).The aqueous fluoride-containing solution, particularly dilute hydrofluoric acid, having a pH of maximum about 2 for the treatment of teeth, is employed particularly by direct application, if desired, before or after the application of a solution containing calcium ions to the teeth.

Abstract: The invention relates to a method of cleaning teeth by applying thereto one or more elements selected from yttrium, scandium and lanthanum and the lanthanides, and to compositions, such as mouthwashes, toothpastes and dental gels, for use in such a method.
