One-part dental compositions and methods for bleaching and desensitizing teeth

Composition and methods that include potassium nitrate for whitening and / or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, dispersed within a solvent, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

Light or heat activated dental bleaching compositions

Dental bleaching compositions are made with a bleaching agent and a stable radiant-energy absorbing compound that acts as a bleaching agent activator. The dental bleaching compositions of the present invention can be one-part, pre-mixed compositions that do not require mixing at the time of treating a patient's teeth but which remain stable over time. The bleaching agent may consist of hydrogen peroxide, either in aqueous form or complexed with urea (carbamide peroxide) or sodium perborate. The bleaching agent activator includes hydrocarbons that are stable in the presence of the bleaching agent, which do not prematurely accelerate liberation of the bleaching agent, but which allow for selective activation of the bleaching agent by irradiation of the bleaching composition with radiant energy. The bleaching composition may optionally include a neutralizing agent to adjust the pH, a carrier to help provide proper consistency and potency, and a stabilizing agent to maintain maximum potency of the bleaching agent over time. The bleaching composition may also include a thickening agent to achieve a selected viscosity. The dental bleaching compositions may be adapted to be loaded into and delivered from a syringe.

Dental bleaching compositions containing sucralose

Dental bleaching compositions that include sucralose. The bleaching agent is dispersed within a carrier, which is optimally sticky and viscous such as a mixture of propylene glycol and silica fume. Anhydrous propylene glycol and / or anhydrous glycerin are especially useful in order to maintain the desired degree of hydration of the perborate being used. Flavorants may be added to enhance the taste of the dental compositions, since they will be used within a person's mouth. For best results, a flexible, thin-walled, comfortable-fitting, custom dental tray is used with the dental bleaching compositions. The dental compositions are sufficiently sticky and viscous so as to adhere and retain a dental tray against a person's teeth which is designed so as to not exert significant mechanical pressure onto the person's teeth.

A method and system to produce biodiesel from a combination of corn (maize) and other agro feedstock may be simarouba, mahua, rice, pongamia etc. Germ is separated (either by wet process or dry process) from corn, crude corn oil extracted from germ and corn starch milk / slurry is heated and cooked in jet cooker to about 105 degree Celsius, enzymes added to convert starch into fermentable sugars in liquification and saccharification process and rapidly cooled down to about 30 degree Celsius. Simarouba fruits syrup, mahua syrup is mixed with corn starch milk (after saccharification). When yeast is added the fermentation takes place for about 72 hours. Thereafter the fermented wash is distilled to produce ethanol. Water consumed in dry process is very less compared to traditional wet process system. Corn oil and mixture of other oils is fed into transesterification (reaction) vessels where ethanol with catalyst, usually sodium hydroxide is added and reaction takes place for about a period of 2-8 hours. Crude biodiesel and crude glycerin as by-products is produced. Excess ethanol removed by distillation process. Crude biodiesel washed with warm water to remove residual soaps or unused catalyst, dried and biodiesel stored for commercial use. Oil extracted from spent bleach mud (used sodium bentonite), a waste product of edible oil refineries may also be utilized for economical production of biodiesel in combination of corn oil and ethanol.
