The invention also relates to an oral care product comprising the oral composition of the invention, a method of bleaching teeth, a method for using said oral care products and the use of oxidoreductases for oxidation of teeth stains.

Abstract: A Revolutionary Dialysis Container for safe dialysis of biological samples is described. A handle with wide top gives a non-slippery grip to lift and carry the container by a human hand. On its bottom, the buffer reservoir possesses a Sample Saver, which is nothing but a flat top plate attached to a vertical side wall. The reservoir holds dialysis buffer and bags containing biological samples. The Sample Saver encloses a bar magnet. The flat top plate and the vertical side wall of Sample Saver have several openings for the free flow of buffer during dialysis. However, these openings eliminate physical contact between dialysis bags and the highly spinning bar magnet. Also, the flat top plate, because of special distribution of openings, suppresses the formation of vortex in buffer during mixing. This preassembled unit also provides safety to long dialysis bags. One can dialyze fast and save time. It is simple to use and practically free of maintenance.

Abstract: An oral antiplaque composition comprising an orally acceptable vehicle and an effective antiplaque amount of 4-alkoxy substituted 2-hydroxy benzophenone compound having the following formula: where X, Y, X′ and Y′ represent hydrogen, and lower straight chain or branched C1-C4 alkyl radicals, C3-C6 cycloalkyls and R represents lower C1-C8 alkoxy radicals.

Abstract: An antiplaque and anticalculus oral composition containing an antimicrobial agent such as chlorohexidine or triclosan and an azacycloalkane-2,2-diphosphonic compound.

Abstract: A method and composition for remineralizing teeth wherein the composition contains a mixture of a casein glycomacropeptide and xylitol.

Abstract: An antibacterial combination of a nonionic halogenated diphenyl ether compound such as Triclosan and hydrogenated lupulone, the combination being particularly effective in inhibiting the growth of gram-positive bacteria and in the preparation of antiplaque oral compositions.

Abstract: Room Air Gel Dryer contains a system of hinges for movement and alignment of frames. It has another system of latches and thumb screws for tightly holding or releasing different frames. Both of the above described systems keep various separate components stay and work together as one unit. Wall plates not only hold this gel dryer horizontal but also make it stand with excellent stability. Special grooves present in the lateral sides assist in separating different frames and in the collection of dry acrylamide gel-cellophane sandwich.

Abstract: An oral lubricant having particular usefulness for alleviating the symptoms of xerostomia based on a beta-glucan polymer in an orally acceptable carrier or vehicle.

Abstract: A process which inhibits bacteria and caries comprising the application of an oral composition containing a substantially water insoluble noncationic antimicrobial agent, such as triclosan, xylitol, and sodium lauryl sulfate as the surfactant and dispersant for the water insoluble noncationic antimicrobial agent.

Abstract: A stable antibacterial oral composition containing a hydrogenated lupulone and an anionic surfactant.

Abstract: A high foaming oral composition comprising in an orally acceptable vehicle, an effective antiplaque, antibacterial compound, and at least about 2% by weight of a mixed anionic/nonionic surfactant system in a weight ratio of about 7:1 to 2:1, respectively, which ratios are effective to increase the uptake of the antibacterial compound to dental tissue so as to enhance the therapeutic efficacy of the administered antibacterial compound.

Abstract: The invention provides an antibacterial oral composition containing an antibacterial compound, a monoalkyl phosphate compound and another anionic surfactant; whereby, the antibacterial effect on dental tissue is substantially increased due to the combined presence of the monoalkyl phosphate compound and the other anionic surfactant in a given weight ratio.

Abstract: An antibacterial, anti-inflammatory compound for use in oral products, of the formulae: ##STR1## Wherein: R.sub.1 and R.sub.2 are straight chain or branched alkyl substituents or cycloalkyls with one or more alkyl substituents.

Abstract: The present invention provides safe products for bleaching teeth. Oral compositions comprising at least one oxidoreductase fulfil said criteria without the presence of peroxide or with only very little peroxide present. The invention also relates to an oral care product comprising the oral composition of the invention, a method of bleaching teeth, a method for using said oral care products and the use of oxidoreductases for oxidation of teeth stains.

Abstract: A multicomponent anticaries dentifrice composition and method of use therefore, having a first dentifrice component containing a fluoride ion source and a second dentifrice component containing a casein glycomacropeptide compound, wherein the components are physically separated before use and are combined immediately prior to application to the teeth, the dentifrice exhibiting enhanced enamel remineralization.

Abstract: An oral composition comprising an orally acceptable vehicle and an effective antiplaque amount of at least one substantially water insoluble noncationic antibacterial agent of the formulae: ##STR1##

Abstract: A dual component antiplaque dentifrice composition in which the first component is an extrudible dentifrice composition containing a nonionic antibacterial agent in which calcium salts are absent and the second component is an extrudable dentifrice composition containing a calcium salt wherein maximum antibacterial agent uptake by dental tissue is achieved when the components and are physically separated prior to use and are mixed upon application to dental tissue.

Abstract: An antiplaque composition comprising a bacteriocin such as nisin and a polyphosphonate.

Abstract: An oral composition and method for use thereof, comprising in an orally acceptable vehicle, an effective antiplaque amount of a noncationic antibacterial agent, and an anionic copolymer formed from monomers of which about 40 to about 90% by weight are hydrophilic type capable of attachment to oral surfaces and about 10 to about 60% by weight are of a hydrophobic type; such oral composition being effective in increasing the uptake of the antibacterial compound to dental tissue so as to enhance the therapeutic efficacy of the administered antibacterial compound.
