Electromagnetic radiation emitting toothbrush and dentifrice system

A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.

Tooth brushing pattern analyzing/modifying device, method and system for interactively modifying tooth brushing behavior

Disclosed are a toothbrushing pattern analyzing/correcting device, a toothbrushing pattern analyzing/correcting method, a method and a system for interactively correcting toothbrushing behavior. The toothbrushing pattern analyzing/correcting device of the present invention includes: a body part formed in the same direction as a toothbrush surface; a sensing unit having a sensor with at least one or more axes for sensing a user's toothbrushing motion and a sensor with one or more axes for sensing two or more toothbrushing positions; and a controller for operating signals input from the sensing unit to classify a user's toothbrushing motion into at least two or more patterns and at least two or more toothbrushing parts. Further, the toothbrushing pattern analyzing/correcting method includes the steps of: detecting the start of a user's toothbrushing; displaying a guiding screen in response to the start of a user's toothbrushing; detecting a user's toothbrushing pattern; analyzing the user's detected toothbrushing pattern; and providing a toothbrushing correction screen with the intention of increasing compliance in accordance with the analyzed result. Accordingly, toothbrushing behavior correction compliance can be further enhanced with a method of interactively correcting a user's toothbrushing behavior through multimedia image substances in real time, and more systematic management and health consultation are possible by building a database of information of the user's toothbrushing behavior.

Laterally-actuated dispenser with one-way valve for storing and dispensing metered amounts of substances

A dispenser for dispensing a substance, such as a pharmaceutical, ophthalmic, dermatological, cosmeceutical, cosmetic or other product, has a body defining a variable-volume storage chamber for storing the product. A dispensing portion of the dispenser is connected with the body and defines a bore coupled in fluid communication with the storage chamber for receiving substance therefrom, and an outlet aperture coupled in fluid communication with the bore. A one-way valve of the dispenser includes an axially-extending valve seat and an axially-extending flexible valve cover seated on the valve seat and defining a normally-closed, axially-extending seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat and the seam is connectable in fluid communication with the outlet aperture to allow the passage of substance through the seam and out of the dispenser. The dispenser further comprises an actuator and piston assembly including a piston receivable within the bore, a manually-engageable actuator connected to the piston for moving the piston between first and second positions relative to the bore to dispense substance within the bore through the outlet aperture, and an integral, dome-shaped spring coupled to at least one of the piston and the actuator for biasing the piston in a direction from one of the first and second positions toward the other.
