Abstract: A mouthpiece that adjusts manually to accommodate a broad range of different size sets of upper and lower teeth in the mouth and yet seals the treatment area from oxygen exposure. The mouthpiece includes light emitting diodes and heat generating resistors all arranged in an array. A series of parallel texture bands are provides to guide and direct the light from the LEDs to diffuse generally evenly onto teeth to be treated. The seal arises from an inner surface of the mouthpiece titling inwardly so that a seal bead seals in the vicinity of the gum above the teeth to be treated.

Abstract: Described herein are rhenium boride compounds having desirable characteristics for a variety of applications, ranging from abrasives and cutting tools to protective coatings.

Abstract: An applicator having a squeezable vessel, an applicator tip, a crenellated ring and a sponge. The vessel contains contents that react upon contact with a reactive ingredient treated onto the sponge. By squeezing the vessel, the contents are urged to leave the vessel to pass through a hollow of the applicator tip to reach the sponge. The sponge has a peripheral edge that faces inward facing surfaces of elastomeric formations of the crenellated ring. The elastomeric formations are each separated from each other in succession. The elastomeric formations at the distal end of the crenellated ring may have a greater depth than that of the sponge, which in turn may have a greater depth than elastomeric formation(s) at a proximal end of the crenellated ring.

Abstract: Dispenser for dispensing a substance onto a substrate, such as a tooth treatment compound onto teeth, includes a vial including a pair of thin members forming a cavity therebetween in which the substance is arranged and a conduit defining an internal dispensing channel communicating with the cavity, an applicator tip arranged in connection with the conduit and including projections adapted to contact the substrate, and a cap including a cavity. The cap removably attaches to the vial and when attached, covers the applicator tip and seals the internal channel. When the cap is detached from the vial and the thin members are squeezed toward one another, the substance in the cavity is urged out of the cavity into and through the internal channel in the conduit and onto the projections to enable it to be brought into contact with the substrate.

Abstract: A mouthpiece that adjusts manually in the mouth and seals the treatment area. It includes light emitters and heat generators. Textured bands guide and direct light to diffuse evenly. A seal bead seals the gum above the teeth. For whitening, a whitening gel is first applied to the user's teeth, the mouthpiece is then positioned in the user's mouth, and the seal bead seals against the user's gums. Then, the light emitter(s) and heat generator(s) are activated to effect the whitening while causing an increase in the temperature enabling the user to mold the mouthpiece to their mouth.

Abstract: Dispenser that dispenses a substance onto a substrate, such as a tooth treatment compound onto teeth, includes a vial including a cavity containing the substance and a projecting portion extending outward from the base. An applicator tip is engaged with the conduit and includes an internal passage communicating with the cavity, and an applicator portion situated forward of the conduit and that includes a plurality of spaced-apart projections at a distal application surface, preferably crenellated fingers. A cap is removably attachable to the vial and when attached, the applicator portion of the applicator tip is accommodated in a cavity of the cap and a sealing stopper extends into the internal passage to thereby seal it. When the cap is removed from the vial and the base is squeezed, the substance is urged out of the cavity through the passage of the applicator tip and onto the projections.

Abstract: A flexible tubular vial is plugged at one end. The plug is pulled out to open the one end and define a gap between the open end of the vial and the plug. A sleeve bounds the gap. The sleeve has a rib as does the vial (or an intermediate component) that block each other so as to limit relative movement of the plug between a retracted relative position that plugs the open end and a cleared relative position that clears the open end. By squeezing the vial, contents of the vial are urged out through interstices in the plug. The contents may be a teeth whitening composition gel that urges out through interstices in the plug to a brush-like applicator to be applied to teeth or may be a topical medicine to be applied to skin.

Abstract: A squeezable hermetically sealed vessel contains a whitening compound and an elongated applicator tip extending outwardly from the vessel. A cap closed and seals the applicator tip and the vessel, but may be removed under manual force. Once the cap is removed, the walls of the vessel may be squeezed together to urges the contents of the vessel to flow through a fluid passage through the elongated applicator tip to reach an accommodating surface. The accommodating surface may either be impregnated with a different material that reacts with the contents of the vessel upon contact or covers a chamber that in turn contains such a different material.

Abstract: A method for effecting an oral treatment of teeth and/or gums using an intra-oral device that has a mouthpiece in which is embedded a flexible circuit board and arrays of spaced apart lamps. The mouthpiece has a curvature. The lamps may be light emitting diodes that generate electromagnetic radiation, preferably in the white and blue light spectrum and the infrared and ultraviolet light spectrum. The arrays are positioned to expose the facial and lingual sides of the teeth and/or gums for effecting the treatment when the mouthpiece is positioned to fit upper and lower rows of teeth within accommodating recesses. The flexible circuit board is flexed to exhibit a curvature that follows a curvature of the mouthpiece. Treatments include whitening teeth, desensitizing teeth, and treating gums to prevent periodontal disease.

Abstract: A single dose hygienic tooth whitener dispenser and applicator has a chamber. The housing is a bottle having an upper end with a neck and threads receiving a threaded sleeve. The sleeve includes a recess receiving a sponge applicator having a bottom surface overlying an upwardly facing opening of the chamber in the bottle. This opening is initially covered by a hermetic seal. An over-cap includes a bottom facing opening slidable over the sleeve and covers the applicator. Within the over-cap, a pin extends downwardly. The pin has a pointed end facing downward. When it is desired to use the inventive device to whiten the user's teeth, the over-cap is pushed down until the pointed end of the pin extends through the applicator and pierces the seal in the opening of the bottle, whereupon tooth whitener may be dispensed and applied.
