| 20090238778 | TOOTH WHITENING COMPOSITIONS, DELIVERY SYSTEMS AND METHODS - The present invention is directed to tooth whitening compositions that are capable of being activated by light energy, where the compositions include a safe and effective amount of riboflavin or a derivative of riboflavin, from about 0.1 to about 50 percent by weight of a bleaching agent and a water-soluble liquid phase; to systems for delivering the photoactivatable tooth whitening compositions to the surface of the teeth, and methods of whitening teeth that include the steps of exposing the photoactivatable whitening composition to light energy under conditions effective to photoactivate the tooth whitening composition and maintaining the composition in contact with the teeth under conditions effective to whiten teeth. | 09-24-2009 |
| 20090317339 | Teeth Bleaching Compositions and Devices - The present invention is directed to an oral care device configured to contact teeth, where the device includes disposed therein a bioactive glass in an amount effective to mineralize teeth when contacted with the teeth under conditions effective to mineralize the teeth; and a tooth-bleaching agent in an amount effective to whiten teeth when contacted with the teeth under conditions effective to whiten the teeth, and to methods for simultaneously mineralizing and whitening teeth utilizing the devices of the present invention. | 12-24-2009 |
| 20100158960 | POROUS POLYMER COATING FOR TOOTH WHITENING - The present invention relates to a tooth-whitening composition comprising (i) a substantially water-insoluble and substantially non-degradable polymer matrix component capable of adhering to the surface of a tooth, provided that if the polymer matrix component is in non-solid form, it is solidifable by chemical alteration; and (ii) gas- or liquid-filled pores embedded in said polymer matrix component, wherein at least a portion of said gas- or liquid-filled pores have at least one size dimension in the range of about 70 nm to about 5 microns, and wherein the gas- or liquid-filled pores and polymer matrix component possess a difference in refractive index of at least 0.1. The invention is also directed to a tooth-whitening system containing the above composition in combination with an applicator device. The invention is also directed to methods for applying the tooth-whitening composition onto teeth. | 06-24-2010 |
| 20110123462 | BIOFILM DISRUPTIVE COMPOSITIONS - In certain embodiments, the present invention relates to compounds, compositions, and methods for disrupting biofilms. In some embodiments, the compounds and compositions comprise unsaturated long chain alcohols and/or aldehydes, or combinations of such compounds. In further embodiments, the present invention contains therapeutic actives to help reduce and/or eradicate the bacteria in the biofilm once the film is disrupted. | 05-26-2011 |
