The present invention provides an orientation independent apparatus for applying a uniform coating of a dental powder as well as a method of operating the orientation independent apparatus. The present invention can be used in the preparation of a replica tooth during restorative dental work. Included in the present invention is an orientation independent dental powder applicator with a powder reservoir having an introductory circumferential plenum chamber, inner circumferential chamber and outer circumferential plenum chamber. Desiccated pressurized air enters the powder reservoir from a desiccant chamber and fluidizes dental powder located in either the inner circumferential chamber or outer circumferential plenum chamber. The powder reservoir is designed to allow pressurized air to flow around the entire perimeter of either the inner circumferential chamber or outer circumferential plenum chamber. The fluidized dental powder then travels into an acceleration chamber and ultimately through an applicator tube directed at a dental site.

The invention discloses a tooth powder which is characterized by comprising anti-staining active ingredient, acid-free desensitization ingredient, odour removal ingredient and base stock ingredient, wherein the anti-staining active ingredient comprises modified phytic acid sodium and urea hydrogen peroxide; the acid-free desensitization ingredient comprises sodium monofluorophosphate and Chinese medicine desensitization agent; the odour removal ingredient comprises angelica root extract and liex rotunda extract; and the base stock ingredient comprises dicalcium phosphate dehydrate, calcium carbonate, silica, soluble saccharin, glycerol, essence, sodium lauryl sulfate and the balance of preservative. When being in fabrication, the tooth powder not only has the functions of cleaning dental plaque, complexing and dissolving pigmentation of tooth surface but also can reduce the irritation to the oral cavity and the aching, limp and allergic feeding can not be caused during use process through a combination technology.

The present invention is directed towards a composition for highly efficient and quick plaque and tartar removal and inhibition including pure ascorbic acid crystals and / or granulars (vitamin C) and an enamel repairing composition such as hydroxyapatite. The composition can contain from about 10% up to 90% of ascorbic acid without compromising the tooth enamel because hydroxyapatite will repair any damage to the enamel. The composition can be used as dental powder, toothpaste, mouthwash, mouth spray and chewing gum in order to cover a wide range of consumers in different settings.

A mixing device for a dental powder jet device, comprising a receptacle for receiving a powder, an inlet for a transport fluid, and an outlet for a powder / transport fluid mixture, the outlet comprising at least one outlet nozzle, the inlet comprising at least one first and at least one second inlet nozzles wherein the outflow direction of the first inlet nozzle intersects the inflow direction of the outlet nozzle, and wherein the outflow direction of the second inlet nozzle is arranged in an offset manner with respect to the outflow direction of the first inlet nozzle.

The invention discloses an oral care composition, tooth powder, toothpaste and mouthwash, and relates to the technical field of oral care. The oral care composition comprises the following componentsin parts by weight: 0.01-5 parts of plant ferment, 0.1-4 parts of buffering agents, 0.3-5.5 parts of complexing agents, 0.2-2 parts of organic peroxides and 0.1-1 part of slow release agents. Attachments, food debris and the like on surfaces of teeth are rapidly decomposed by the plant ferment; tooth stains and dental calculus dissolve with the complex compounds; and the organic peroxides good instability cooperate with the stable slow release agents to form an effective component membrane on the surfaces of the teeth, so that the effective acting time can be prolonged, enamel and gum cannotbe damaged, and formation of dental plaque, gingivitis and the dental calculus can be restrained. The tooth powder, the toothpaste and the mouthwash using the oral care composition can realize betteroral caring and tooth whitening effects.
