A mouthpiece cleaning device includes a U-shaped mouthpiece skeleton that defines opposing channels to receive a user's teeth therein. The channels each have a respective teeth facing surface, and transducers are disposed along the channels at the respective teeth facing surfaces. UV LEDs are disposed along the channels at the respective teeth facing services. The UV LEDs are interspersed with the transducers.

A customized oral irrigator which is adapted to the user's dentition, has multiple nozzles or cutout openings to point to the area to irrigate. User can anchor such device by biting with the teeth and irrigate the teeth and gum, especially between the teeth and under the gum, in one instance. Such a device is fast and effective. It will be beneficial to everyone but will especially benefit busy professionals, children, seniors, handicapped, disabled, and other users who have difficulty cleaning teeth, for example people who wear dental devices such as braces. This device is meant to combine oral care procedures such as tooth brushing and dental flossing in one instance and will yield better dental hygiene and with better compliance than conventional brushing and flossing and conventional single channel oral irrigators.

A toothbrush having one or more light sources with an electronic interlock control device preventing operation of the light source when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of about 400 nm to about 1000 nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head.

An acquisition kit, including: a mouthpiece intended for being placed into the mouth of a patient and including a reference mark; and an image-acquisition apparatus including a screen for viewing an image that can be acquired, computer memory containing information on target acquisition conditions, and a computer program comprising program code instructions for displaying on said screen a reference in a position such that, when the reference mark matches the reference on the screen, the acquisition apparatus complies with the target acquisition conditions.

Disclosed are to a plasma enhancement member, and a plasma supplying apparatus and a medical instrument including the same. The plasma enhancement member includes a coupling part coupled to an apparatus for generating plasma, an enhancement material accommodating part configured to accommodate an enhancement material for enhancing an operation of the plasma, and a plasma discharge part configured to discharge the plasma including the enhancement material.

A multi-phase oral composition for whitening teeth.

A method such as polishing the tooth under suitable conditions to enhance whitening effects. The following steps 1 to 3 are performed in number order, using a tooth polishing portion made of resin or resin composition having uneven surface, and citric acid or citric acid metal salts dispersed or dissolved in a gelatinous medium: Step 1: Apply a gel of 1 to 73 % citric acid or citric acid metal salts to the tooth surface. Step 2: Heat the tooth surface with the heating plate at 37° C.-45° C. for at least 3 minutes. Step 3: Scrub the tooth surface with the tooth polishing portion to provide friction while removing the gel.

An oral care composition is disclosed. The oral care composition includes (A) an adhesive agent comprising an alkylated polyvinylpyrrolidone, (B) a miscibility component comprising an acrylic acid-acrylate copolymer, and (C) a plasticizer comprising a polyalkylene glycol. An oral care device is also disclosed. The oral care device includes an oral care layer comprising the oral care composition and a whitening agent. A method of preparing the oral care device is also disclosed, and includes extruding the oral care composition to give the oral care layer, and preparing a laminate comprising the oral care layer. The method may further include processing the laminate to give the oral care device, which may be prepared as an oral care strip or an oral care tray.

An oral appliance having a body, the body including a plate member and a lighting system. The plate member having a first surface, the first surface including a top portion, a center portion, and a bottom portion. The lighting system includes a first lighting sub-system having at least one first light source, where the at least one first light source arranged in the center portion of the plate member, and a second lighting sub-system having at least one second light source, where the at least one second light source arranged in the top portion of the plate member and/or the bottom portion of the plate member. The at least one first light source is arranged to produce a first light at a first wavelength and the at least one second light source is arranged to produce a second light at a second wavelength.
