20080274065Oral Care Regimen - The invention includes methods of cleaning an oral surface, maintaining oral health and/or increasing oral health. Such methods encompass contacting an oral surface with a primary oral care composition at least once daily, contacting the oral surface with a periodic oral care maintenance composition at least once monthly, wherein the periodic oral care maintenance composition comprises a basic amino acid, in free or salt form and optionally contacting the oral surface with a periodic oral care cleaning composition at least once monthly. The periodic oral care cleaning compositions suitable for use in the method comprise an abrasive system.11-06-2008
20090202450ORAL CARE PRODUCT AND METHODS OF USE AND MANUFACTURE THEREOF - This invention relates to oral care compositions comprising an effective amount of a basic amino acid in free or salt form, together with an anionic surfactant, and to methods of using and of making such compositions.08-13-2009
20090202451ORAL CARE PRODUCT AND METHODS OF USE AND MANUFACTURE THEREOF - This invention relates to oral care compositions comprising a basic amino acid or salt thereof, and a small particle fraction: and to methods of using and of making these compositions.08-13-2009
20090202454ORAL CARE PRODUCT AND METHODS OF USE AND MANUFACTURE THEREOF - This invention relates to oral care compositions comprising an effective amount of a basic amino acid in free or salt form, together with an antibacterial agent, and to methods of using and of making such compositions.08-13-2009
20090202455ORAL CARE PRODUCT AND METHODS OF USE AND MANUFACTURE THEREOF - This invention relates to oral care compositions comprising an effective amount of a salt of a basic amino acid the salt having a pH in an unbuffered solution of less than about 7.5; an effective amount of a soluble fluoride salt; and a particulate material which has a pH in an unbuffered solution of less than about 7.5; and to methods of using and of making such compositions.08-13-2009
20090202456NOVEL SALTS AND THEIR USES - The invention relates to novel arginine salts, compositions comprising them, and their uses.08-13-2009
20090320225Oral Care Implement With Mechanical Energy Harvesting - A mechanical energy harvesting toothbrush may employ circuits and devices to convert mechanical energy into electrical energy. Such conversion can be done using piezoelectric devices to convert stresses and strains from bending of the toothbrush head and/or bristles during use, and can be done using electromagnetic generators involving passing a magnet through a coil to induce current. The resulting electric energy may be rectified, and stored in a storage device, such as a capacitor or rechargeable battery. A switching circuit may be configured to detect the level of energy stored in the storage device, and to close an electrical connection when a predetermined level of energy (e.g., a charge) has been reached. The predetermined level may correspond to a desired amount of brushing (e.g., taking into account stroke length and force, and the number of strokes), and the closing of the electrical connection may be used to power output devices when that desired amount of brushing has been reached.12-31-2009
20110052509COMPOSITIONS COMPRISING BASIC AMINO ACID AND SOLUBLE CARBONATE SALT - This invention relates to compositions comprising a basic amino acid free or salt form and a soluble carbonate or bicarbonate salt.03-03-2011
20110076090ORAL CARE IMPLEMENT WITH LIQUID DELIVERY SYSTEM - An oral care implement (03-31-2011
