The present invention relates to an electric toothbrush that includes a head part and a handle part having a shape connectable to the head part and supplying a driving voltage to the head part according to a user's control. The head part may include a toothbrush head formed with a plurality of bristle holes where toothbrush bristles are disposed and a first through hole and a second through hole spaced apart from each other, a head body extending from the toothbrush head and having an inner passage connected to the first through hole and the second through hole, a head cover which closes the inner passage of the head body, and a first electrode rod and a second electrode rod inserted through the inner passage of the head body, whose one ends being positioned in the first through hole and the second through hole, respectively, and the other ends being exposed to the outside through the head cover, respectively.

A dental medicament applicator is disclosed. In one embodiment, a placement device is sized for insertion at a dental site, such as an interproximal site. The placement device includes a central body and at least one active matrix secured to the central body containing a topical substance, such as a fluoride-containing chemical agent, silver diamine fluoride, or a peptide-based chemical agent, for example. One or two wings extend from the central body to provide subterminal opposition surfaces to hold the placement device during placement. The one or more wings are free of the topical substance. The active matrix, in response to being physically affixed to the dental site, delivers the topical substance at a controlled rate to the dental site while the placement device dissolves at a quicker controlled rate.

For improving the quality of use of intraoral orthodontic devices (1) such as dental splints (2) to be worn on teeth as well as for increasing their functionality, such devices (1) are fabricated at least in part, but preferably fully from bio-based materials (5). In particular when using a design featuring a cap layer (4) covering an inner stiff core (3) and including a bio-based material (5), which can be additionally chosen such that it can take-up a significant amount of liquid by swelling, both the micro-deformability of the device (1) can be improved—resulting in increased wearing comfort for the patient and less microplastic contamination for the patient through fossil-based plastic abrasions—and novel functions can be realized, for example releasing substances (9) such as drugs or flavor molecules or bio-based antimicrobial or protective agents from the device (1).

An oral treatment device for dispensing an oral treatment composition onto a user's teeth. The oral treatment device may include a storage and delivery component and an applicator component. The storage and delivery component may include a body having a reservoir, a frangible capsule containing the oral treatment composition located in the reservoir, and a delivery member. The applicator component may include a pad portion formed of a liquid absorbing material. The applicator component may be alterable between an attached state whereby the delivery member is fluidly coupled to the pad portion and a detached state whereby the applicator component is detached from the storage and delivery component and can be placed into contact with the user's teeth. The frangible capsule may be in a sealed state until broken by a user at which point the oral treatment composition may flow into the pad portion of the applicator component.

An oral appliance, a method of making the oral appliance for delivering an antimicrobial composition to an oral cavity and a method of treatment are provided. The oral appliance has an exterior surface and an interior surface, the interior surface of the oral appliance configured to contour at least a portion of teeth and/or soft tissue areas of the oral cavity. The antimicrobial is dispensed by itself or as a composition in a carrier at discrete regions of the interior surface, the exterior surface or both the interior surface and the exterior surface of the oral appliance for delivering the antimicrobial or an antimicrobial composition to the oral cavity, wherein the antimicrobial is present in the carrier in an amount of about 0.01% to about 20% w/w, v/v or w/v based on a total weight or a total volume of the carrier.

A medicament delivery tooth covering is provided. The medicament delivery tooth covering includes a tooth covering and a carrier layer. The tooth covering has at least one attachment surface that covers a surface of teeth of a user. The carrier layer is arranged on the at least one attachment surface. The carrier layer carries a medicament, and the medicament contains powder particles. When water is introduced to an inner side of the at least one attachment surface of the tooth covering, the water is allowed to pass through the carrier layer, so that the medicament contacts the water. The powder particles are dual-structured powder particles that have a core structure and an outer layer structure that encloses an outer side of the core structure.

Oral appliance delivery trays for use in maintaining or improving oral health, particularly the sub-gingival region, are provided. Methods of manufacturing individualized oral appliance delivery trays are provided. Pre-fabricated oral appliance trays comprising a compound pre-disposed therein are provided. The compositions and methods may be used to maintain or improve oral, periodontal and systemic health or to prevent or slow oral, periodontal or systemic health issues related to the oral cavity.

This disclosure relates to various systems and methods related to preventative laser-based treatment of a dental tissue; for example, to prevent a patient from forming cavities. In some instances, a laser-based treatment system can generate a laser beam pulse with a fluence profile at a treatment site that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. In some instances, the laser-based treatment system can direct the laser beam to various locations within a treatment site according to a temporal and/or spatial pattern, that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. Many other systems and techniques for preventative and other laser-based treatment are also described.

An oral appliance for delivering a medicament to an inflamed tissue inside an oral cavity is provided. The oral appliance has an interior surface configured to contour at least a portion of teeth and/or soft tissue areas inside the oral cavity, the interior surface of the oral appliance having a medicament disposed at a discrete region of the interior surface of the oral appliance, the medicament configured to contact a top portion of the inflamed tissue inside the oral cavity when the oral appliance is worn to cause delivery of the medicament to at least the top portion of the inflamed tissue. A method of making the oral appliance and a method of treating an inflamed tissue inside an oral cavity using the oral appliance is also provided.
