The invention discloses a tooth bleaching liquid which is harmless to tooth enamel and its application method. The tooth bleaching solution includes a bleaching agent and a thickening agent. Wherein the bleaching agent is a typical peroxide, and the thickener is polyvinylpyrrolidone. The two make up a viscous or viscous tooth bleaching solution. Choose to add alkaline reagents to the bleaching solution, increase light or heat can promote bleaching. Dental trays can be used for bleaching. The bleaching solution is pushed into the tooth tray by a syringe, and the syringe can be a single-chamber, double-chamber or multi-chamber syringe, which contains various components of the bleaching solution. The bleaching solution can be attached to a strip of elastic material and placed on the teeth for bleaching.

An electrospinning device is described for producing fibrous porous structures. The device is adapted for providing a predetermined distance profile for the distance between outlets of the electrospinning device and the receiving surface. The latter may be obtained by geometrically adapting the electrospinning device or by moving the outlets with respect to the receiving surface during growth of the fibrous structure. A fibrous structure obtained by the described electrospinning device is also described which comprises fibres, wherein the diameter of the fibres has a predetermined profile along a dimension of the electrospun fibrous structure. Furthermore application of the laminated structure for wound dressing and teeth bleaching is discussed.

A method of bleaching a plurality of adjacent teeth is disclosed. The teeth having facial and lingual surfaces. The method includes applying a tooth bleaching delivery system to a plurality of adjacent teeth, wherein the tooth bleaching delivery system includes a strip of material and a tooth bleaching composition having a peroxide active.

A tooth-bleaching material characterized by comprising: hydrogen peroxide and / or a compound which generates hydrogen peroxide in an aqueous solution; a dicarboxylic acid anhydride; a basic compound; and a thickener. Also provided is a method of tooth bleaching characterized by adhering the tooth-bleaching material, optionally after being diluted, to the surface of a stained tooth and irradiating it with light. Thus, the coloring matter (coloration, discoloration) deposited on a tooth is bleached and removed. The tooth-bleaching material is safe and convenient for use and has a high bleaching effect. The method of tooth bleaching employs the tooth-bleaching material.

Dental bleaching compositions, for example in the form of liquids, gels, creams, pastes and ointments, comprising a peroxide releasing compound and from 1% to 35% by weight of a potassium-containing compound such as potassium nitrate, wherein the potassium nitrate is present in a safe and effective amount to prevent tooth hypersensitivity in the patient during the bleaching process. The potassium nitrate contemplated by the invention is compatible with peroxide yielding bleaching compounds such as peroxide, carbamide peroxide, calcium peroxide, zinc peroxide, magnesium peroxide and sodium perborate. Potassium nitrate is complimentary and synergistic with the peroxide bleaching agents contemplated by the invention and enhances the release of oxygen to the tooth enamel. Also contemplated are methods of bleaching teeth comprising application of the dental bleaching compositions of the invention.

A teeth whitening device includes a generator configured to generate a teeth whitening fluid that whitens teeth and humidified gas, a mouthpiece configured to supply the teeth whitening fluid and the humidified gas, and a coupling part that couples the generator and the mouthpiece with each other. The mouthpiece includes a first supply port through which the teeth whitening fluid is supplied, and a second supply port through which the humidified gas is supplied, the second supply port being separated from the first supply port. The mouthpiece further includes a first supply passage configured to guide the teeth whitening fluid to the first supply port, and a second supply passage configured to guide the humidified gas to the second supply port, the second supply passage being separated from the first supply passage.

The invention discloses a double-functional tooth mineralization and bleaching paste, a preparation method and an application thereof. The tooth bleaching preparation of the invention contains not only peroxide bleaching ingredients, but also mineralization ingredients of calcium phosphate salt, which can be used in bleaching teeth. At the same time, it induces the mineralization of teeth. The preparation of the invention can overcome the demineralization side effects of tooth bleaching preparations on the current market by inducing the mineralization of the tooth surface. The preparation of the present invention contains strontium compound and induces mineralization to seal dentin tubules, which can reduce the side effect of dentin hypersensitivity caused by bleaching. The preparation of the invention has good mineralization activity, so it can be used for the remineralization treatment of teeth. The preparation of the invention can induce the mineralization of teeth, seal the dentine tubules, and can be used for the treatment of dentine hypersensitivity.
