Abstract: The present invention is directed to a process for electrochemically whitening a tooth, the process comprising: a) contacting the tooth with a whitening gel that is located in a dental device, the dental device comprising a positive electrode and a negative electrode; b) flowing a current between the positive electrode and the negative electrode through the whitening gel to whiten the tooth; wherein the whitening gel comprises: water; a bleaching agent; a thickener composition comprising a non-ionic compound; a surfactant; and an electrolyte source comprising a first conductive salt.

Abstract: Described herein are oral care compositions comprising a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, together with particular co-polymers as additional excipients; including some embodiments which further comprise a calcium abrasive.

Abstract: An oral irrigator tip (120) for an oral irrigator (100). The oral irrigator tip (120) may be configured for coupling to an oral irrigator (100) for purposes of irrigating a users teeth, gums, and interproximal regions. The oral irrigator tip (120) contains a dispensing member (150) in its interior, and the dispensing member (150) leaches an oral care agent during use as a fluid such as water flows past the dispensing member (150) within the interior of the oral irrigator tip (120). The oral irrigator tip (120) may be a monolithic structure. The dispensing member (150) may be non-removable from the interior of the oral irrigator tip (120), such that upon depletion of the oral care agent from the dispensing member (150) the entire oral irrigator tip (120) is replaced. The dispensing member (150) may be in the shape of a torus such that the dispensing member (150) does not impede the flow of the fluid through the oral irrigator tip (120).

Abstract: Described herein, are personal care compositions comprising taurine in combination with arginine and glycine, and methods for using the compositions to effect reduction of skin irritation and or inflammation, and/or improving barrier repair of the skin.

Abstract: An oral care system with coaching features. The oral care system may include indicator units to indicate to a user when plaque is present on the oral surfaces and to indicate to a user when it is time to move to a different area of the oral cavity for cleaning. The oral care system may include a feature whereby a user can silence the indicator function so as not to be alerted of the detection of plaque or other oral maladies during a cleaning session. The oral care system may include a light ring which surrounds a button on the handle to inform a user about the amount of time elapsed during a cleaning session.

Abstract: An oral care system includes: an oral care device including a head having a reference face; and a plurality of sensors configured to generate sensor data, the sensor data including: motion data and orientation data corresponding, respectively, to motion measurements and orientation measurements of the reference face during a freeform oral care routine; and image data generated from external images of the oral cavity during the freeform oral care routine; and at least one programmable processor communicably coupled to the plurality of sensors, the at least one programmable processor configured to: generate transformed sensor data from the sensor data, the transformed sensor data comprising the orientation data transformed to be expressed in terms of an angular orientation system, the motion data, and enhanced image data, the enhanced image data representing each external image of the oral cavity combined with a representation of corresponding transformed orientation data.

Abstract: A teeth whitening system that emits electromagnetic radiation onto surfaces of a user's teeth and may also dispense a tooth whitening material for contact with the user's teeth. In one aspect, the teeth whitening system includes a mouthpiece comprising a wall and a bite platform extending from the wall that collectively define a first channel for receiving a user's teeth and an electromagnetic radiation source coupled to the mouthpiece and configured to emit electromagnetic radiation onto surfaces of the user's teeth that are positioned in the first channel. The teeth whitening system may also include an opening in the wall through which a tooth whitening material may be dispensed into the channel. The tooth whitening system may alternatively include apertures in the wall or bite platform through which a tooth whitening material can be dispensed.

Abstract: This invention relates to oral care compositions comprising a basic amino acid or salt thereof, a zinc source, and a preservative, as well as to methods of using and of making these compositions.

Abstract: An oral care composition having a soluble zinc polyphosphate complex made by combining ingredients including an inorganic zinc salt, and a plurality of long chain polyphosphates having 6 or more phosphate polymer units, the relative amount of inorganic zinc salt and long chain polyphosphates providing a phosphorus to zinc mole ratio of at least 6:1. Further provided is a method of treating a subject suffering from dentinal sensitivity applying the oral care composition to the teeth and gums of the subject.

Abstract: An oral care refill head and an oral care kit comprising the same. The oral care refill head may include a sleeve portion, a head portion, and an elastomeric prophy cup. The sleeve portion may have an inner surface that defines an internal cavity for receiving a portion of a stem of an oral care implement handle therein so that the oral care refill head can be repetitively attached to and detached from the oral care implement handle. The elastomeric prophy cup may comprise an outer surface that forms at least a portion of a peripheral side surface of the head portion. The elastomeric prophy cup may be formed by injection molding an elastomeric material onto a support portion of the head portion. The oral care refill head may be packaged together with a store of an anti-sensitivity oral care material to form a kit.

Abstract: Personal care compositions and personal care compositions formulated to preserve pigment associated with a skin tattoo, improve the health skin, and/or improve the appearance of skin arc disclosed herein.

Abstract: Described herein are personal care compositions comprising a liquid carrier; alkyl glyceryl ether; xanthan gum; an ester of glycerin and a C8-18 fatty acid; polyol; and an alkali salt of a C14-22 fatty acid.

Abstract: A system for determining an oral care condition within an oral cavity. The system may include an intraoral device which has a light source for emitting light within the oral cavity and a camera to capture an image of at least one tooth and adjacent gums. The system may include one or more processors configured to: receive the image of the at least one tooth and adjacent gums, differentiate the at least one tooth and the adjacent gums adjacent as a tooth segment and a gums segment, input the gums segment into a machine learning model, and determine, via the machine learning model, the oral care condition based on the gums segment input into the machine learning model.

Abstract: An oral care implement kit which incorporates a handle, a first head, and a second head. The handle has a vibration generation device, a processor, a memory, and a sensor. The first head and second head are configured to be detachably coupled to the handle. The processor is operably coupled to the vibration generation device and the sensor. The sensor is configured to sense which of the first and second heads is coupled to the handle.
