摘要:
This invention relates to methods and apparatus for achieving microbiological control, especially using active sources that generate hypochlorous acid vapor with reduced levels of chlorine vapor. These methods are effective in confined spaces and sealed containers. The active sources may be contained within permeable containers and may be actively dispersed. The active sources may be in the form of solids, liquids or gels.
摘要:
A peroxide product is provided. The peroxide product includes a package having a headspace, a substrate disposed within the package, and a thin layer of a composition having a peroxide active and a polyol, wherein the thin layer is disposed adjacent the substrate. The peroxide product also includes at least one means for increasing the stability of the peroxide active of the composition. The thin layer of the composition has at least about 43% of its original concentration of the peroxide active at twelve months after manufacture when stored at about 25° C. and in the absence of light.
摘要:
Dental bleaching methods and kits employ a dental bleaching composition, a protective composition and a barrier layer. The dental bleaching composition is positioned so as to contact a person's tooth surfaces. The protective composition is positioned so as to shield a person's gingival tissue from the bleaching composition during tooth bleaching. The barrier layer protects at least the bleaching composition from saliva and/or mechanical forces during tooth bleaching. The dental bleaching composition and protective composition can be in the form of a sticky and viscous gel. The protective composition may alternatively be a flexible polymerizable material. The barrier layer may be a substantially flat sheet, strip or patch, or it may comprise a dental tray.
摘要:
A tooth whitening substance formed into a thin layer is provided. The tooth whitening substance includes a polyox resin and a tooth whitening active. The polyox resin adheres the thin layer to a plurality of teeth for a sufficient time to allow the tooth whitening active to act upon the plurality of teeth.
摘要:
A tooth whitening product is provided. The tooth whitening product includes a strip of material sized to cover the front surface of one or more teeth and soft tissue adjacent the front surface of the teeth. A thin layer of a tooth whitening composition is disposed on the strip of material. The whitening composition contains a peroxide active with a concentration greater than about 7.5% by weight of the tooth whitening composition, and the tooth whitening composition has a peroxide density less than about 1.3 mg/cm2.

摘要:
An oral care composition comprises two components. A first such component comprises a first orally acceptable vehicle, a whitening agent and a fluoride salt providing fluoride ion in a total amount of at least about 1,200 ppm of the gel component. A second such component includes a second orally acceptable vehicle and a component that is incompatible with the whitening agent. The second component can comprise a clay-based thickening agent.
摘要:
A preparation for bleaching teeth, comprising 0.3 to 30% by weight of a bleaching component selected from hydrogen peroxide or carbamide peroxide, 4 to 80% by weight of water, 0.05 to 1.00% by weight of a complexing agent selected from the group of the biphosphonates, and 0.1 to 3.0% by weight of a thickener, the preparation exhibiting a pH value in the range from 4 to 7 and a viscosity in the range from 1000 to 120 000 mPa·s (measured with a Brookfield RVF; up to 40 000 mPa·s spindle 4/4 rpm; from 40 000 mPa·s spindle TE/4 rpm; Helipath), the preparation being used in particular in an applicator which exhibits an applicator head which can be impregnated with the preparation to act upon the surfaces of the teeth of the user.
摘要:
A method for preventing tooth decay by initially treating the tooth surface with a laser with a coherent or noncoherent light source. This process makes the tooth more resistant to acid and more able to bond fluoride, thus requiring a lower concentration of fluoride. The method allows for a deeper penetration of the tooth then previously accomplished with other methods.
摘要:
A method of treating root canals includes directing an oxidizing gas onto an opened root canal and containing the oxidizing gas at the opened root canal for a period of time sufficient to kill microorganisms therein. Thereafter, the oxidizing gas is removed from the opened root canal.
摘要:
A packaged tooth whitening product is provided. The package includes a substrate having a first side and a second side, wherein the substrate is sized for use in a human user's oral cavity. A first composition including a tooth whitening agent is disposed adjacent the first side of the substrate. A second composition including an aesthetic agent disposed adjacent the second side of the substrate.
