Provided are methods for collecting saliva from the oral cavity of a mammal comprising: placing a mouthpiece of a device comprising the mouthpiece in the oral cavity of a mammal, the mouthpiece comprising a chamber defined by front and rear inner walls and a base inner wall of the mouthpiece, each of the front and rear inner walls of the chamber comprising a plurality of openings, and a switch disposed in the mouthpiece; and the device further comprising a saliva collection reservoir, a fluid supply reservoir, a pump, and means for directing fluid through said device; activating the switch disposed in the mouthpiece to pump saliva from the oral cavity to the saliva collection reservoir for collection; deactivating the pumping of saliva to the saliva collection reservoir; and subsequently pumping fluid from the fluid supply reservoir to the mouthpiece for cleaning or treatment of the oral cavity.

An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises a lamp support structure comprising a lamp support surface and is formed of a first material. A flexible lamp is mounted to the lamp support surface so that a light emitting surface of the flexible lamp assumes a concave curvature, thereby forming a lamp assembly. A guard component is overmolded to the lamp assembly. In one embodiment, the oral treatment device may be a teeth whitening device.

The present disclosure provides a patch which is attached to a tooth or oral mucous membrane and releases an active ingredient to a portion attached, in which the patch comprises a drug layer having an adhesive surface attached to the tooth or oral mucous membrane and a backing layer laminated on the drug layer, and comprises at least one reticular structure inside the drug layer, and is divided into at least 2 drug layers at the boundary of or by the reticular structure. In particular, the patch have a restricted extensibility.

An electrolysis device may include: a housing comprising a container having an open end, the container configured to contain a liquid when the container is oriented in an upright position; and an electrolysis circuit comprising: a power source; a plurality of electrodes disposed within the container and electrically coupled to the power source; an orientation switch electrically coupled to the power source, coupled to the housing, and oriented to switch when the container is oriented in the upright position; and a control circuit electrically coupled to the power source, the electrodes, and the orientation switch, wherein the electrolysis circuit is configured to operate when the electrodes pass an electric current above a predetermined current threshold and the container is oriented in the upright position.

A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

An oral treatment device and a method of using the same. The oral treatment device includes an intraoral mouthpiece configured for placement into a mouth of a user, which includes a lamp having a top edge and a bottom edge, a plurality of first electromagnetic radiation emitting elements that emit light in a first wavelength when activated, and a plurality of second electromagnetic radiation emitting elements that emit light in a second wavelength when activated. The first electromagnetic radiation emitting elements are positioned along the lamp to emit light onto the user's teeth and the second electromagnetic radiation emitting elements are positioned along the lamp to emit light onto the user's teeth.

The invention relates to a mouthpiece and method for antibacterial treatment of intraoral surfaces. The mouthpiece comprises a body made of heat conducting material, the body comprising tilted facial and lingual outer surfaces and facial and lingual inner surfaces adapted to face facial and lingual surfaces of teeth, respectively. A light source is attached to the body's tilted surface and adapted to deliver light to surfaces of teeth, the light source being positioned on at least one of said outer surfaces and adapted to deliver said light via said inner surfaces to both the facial and lingual surfaces of the teeth.

Provided is an oral care product comprising an effective amount of a soluble orally acceptable sulfate, e.g., sodium or potassium bisulfate, in a buffered, electrically conductive medium, which product is useful in a method for in situ production of per sulfate (S.sub.2O.sub.8.sup.2−), and methods of making and using the same, for example for whitening the teeth.

The disclosed invention relates to a system and method for treatment of a dental hard tissue. The system can include a laser source for generating a laser beam; at least one optic in optical communication with the laser source and adapted to define and direct a non-ablative laser radiation to a treatment surface of the hard dental tissue; and a conduit adapted to apply a whitening treatment to the treatment surface, wherein application of both the non-ablative laser radiation and the whitening treatment results in a ΔE measurement of at least 2.5 times greater than a treatment surface without application of the non-ablative laser radiation.

Systems, methods, and devices for producing appliances for expansion of the arch of a patient are provided. An arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The retention portion comprises a flexible portion and a stiff portion. The force generating portion applies a force to move teeth associated with the flexible portion, while the stiff portion resists movement of its associated teeth. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.
