International Classification:

A61C 5/06

US Classification:

433 90

Abstract:

The present invention includes an improved dental mixing device with a barrel, a mixing tip, and a plunger. The plunger moves dental material through the barrel where it is mixed using a mixing tip. The mixing tip includes an auto-aligning fitting female element configured to align with an auto-aligning fitting male element of the barrel. This auto-alignment simplifies the attachment between the mixing tip and the barrel, saving the user the time and effort. The mixing tip also includes a seal component with a soft material (or component) to insert into the auto-aligning fitting element which is a hard material (or component) to achieve an ideal seal. The seal component and auto-alignment fitting element can be combined together into one component instead of two components.

Abstract:

A multi-component oral care formulation composed essentially of a first antiseptic composition and a second activating composition and multi-compartment delivery systems thereof, which are beneficial for stable storage and instant catalyzation and activation, are provided. The first composition comprises antiseptic compounds such as peroxygen compounds and colloidal silver as antiseptic agent and stabilizers and steric retarders that diminish the potential decomposition of the antiseptic compounds during storage. The second composition comprises peroxygen activation compounds that catalyze the breakdown of the antiseptic compounds in the first composition for more effective antiseptic action, at least one water soluble zinc compound that transforms the volatile sulfur compounds (VSC) into insoluble compounds, and chelating agents that effectively remove the tartar, and essential oils that help alleviate dry mouth through saliva stimulation, to promote overall oral health by providing multiple functions.

Abstract:

A multi-film delivery system for a multi-component tooth whitening, desensitization and remineralization composition is disclosed which comprises a first orally dissolvable film made of a liquid-soluble or liquid dispersible polymer system containing an activation compound or complex and desensitizing agents and/or remineralizing agents and/or anti-inflammatory agents, and a separate second orally dissolvable film made of an inert hydrophilic polymer system containing a tooth whitening compound, such as hydrogen peroxide or sodium perborate, stabilizers and thickeners, and/or desensitizing agents and/or remineralizing agents and/or anti-inflammatory agents, which, when applied together on teeth surfaces, the activation compound/complex on the first film activates the tooth whitening compound in the second film, and accelerates the release of active bleaching radicals for accelerated whitening action. The first and second films are maintained separate from one another until application. The first orally dissolvable film is placed on a surface of the tooth, then immediately hydrates thereby becoming gelatinous upon contact with saliva, and initiates its adhesiveness, the second orally dissolvable film is then placed on top of the first orally dissolvable film, the activation compound/complex on the first film reacts with the tooth whitening compound in the second film and accelerates the release of active bleaching radicals for rapid whitening action. The dissolution of the first dissolvable film is controlled by interaction with the wearer's saliva or the fluid or liquid contained in the composition of the second orally dissolvable film.

Abstract:

An infinitely adjustable training mask for simulating the increased breathing resistance level at higher altitudes including an air-impermeable mask body covering the nose and mouth of the wearer, an infinitely adjustable inhalation resistance assembly extended through the mask body, a replaceable particulate air filter to provide respiratory protection when the wearer inhales, and a drinking device for hydration and consumption of foods. The inhalation resistance assembly contains a stationary aperture component and a rotating dial aperture component for adjusting the sizes of the overlapping inhalation adjustment apertures to achieve the desired breathing resistance level. Upon exhalation of the wearer, the exhaled air is discharged through a flexible one-way check valve controlled exhalation channel. A replaceable particulate air filter which can be easily placed inside or removed from the internal cavity of the infinitely adjustable inhalation resistance assembly helps to reduce inhalation exposures to airborne particles during outdoor training sessions. The drinking device enables the wearer to conveniently hydrate or consume foods without taking the mask off, thus allowing maximum amount of wear time to improve training efficiency. A strap is connected to the mask body to be positioned about the head of a wearer to securely maintain the mask during training.

International Classification:

A61C 19/06

Abstract:

The invention relates to nano-sized complexes formed by associating or attaching amorphous calcium phosphate (ACP) and/or amorphous calcium fluoride phosphate (ACFP) with an amphiphilic polymer surfactant (APS) and a bioadhesive polymer. The bioadhesive polymer may serve as a connector or an anchor to attach the nano ACP-APS or ACFP-APS to the tooth surface and to chemically bond the calcium in the enamel to the calcium ions in the nano ACP-APS or ACFP-APS complexes, thus allowing for more controlled release of remineralizing components into the oral cavity. Methods of use of the composition and kits are also disclosed.
