The present invention relates to an electric toothbrush that includes an outer case including a handle part having a tubular shape, and a head part extending from the handle part and having an opening area open to front; first and second electrodes disposed in the opening area and providing electromagnetic waves corresponding to a driving signal; and a head cover having a plurality of bristle holes, a first electrode hole, and a second electrode hole, which are formed therein, and closing the opening area. The first and second electrodes may penetrate the first and second electrode holes, respectively, and be exposed to outside.

The invention relates to the use of a powder in a powder jet device for cleaning tooth surfaces by powder spraying, wherein the powder comprises cyclodextrin. The invention also relates to a process for cleaning tooth surfaces with a powder jet device, wherein the powder comprises cyclodextrin and the invention relates to a powder or powder mixture for use in a powder jet device, wherein the powder or powder mixture comprises cyclodextrin.

Rotating dental systems and related guards and methods are disclosed. In some instances, a guard may be configured to prevent material from building up on at least a portion of the dental system. The guard may be configured to prevent materials from being discharged from the dental system. In some embodiments, the guard may also be configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure may include bristles.

A shell-shaped dental appliance includes: a body which is an integral shell and forms a cavity for receiving teeth; and an anti-caries film which has a certain thickness, and is formed on at least a partial area of an inner surface of the body, and is able to react with saliva to release fluoride ions.

Various embodiments for cleaning carious regions of a tooth are disclosed herein. For example, a dental apparatus can include a fluid platform having a chamber sized and shaped to retain fluid. The chamber can be configured to be coupled to the tooth over the carious region. A pressure wave generator having a distal end may be configured to be positioned in the chamber. The pressure wave generator may be configured to generate pressure waves in the retained fluid sufficient to clean the carious region.

A dental polishing cup for holding a dental treatment material, having a body with an elastic material, the body having a length along a longitudinal axis, a proximal end, a distal end, and a round cross-section taken perpendicularly to the length, wherein the body has a distal diameter at the distal end, the body further defining a cup cavity with an opening at the distal end; and wherein a portion of the body defines an enhanced-flexibility band (EFB) situated circumferentially at a distance from the distal end, the EFB formed from a material that is more flexible than other portions of the body, and the distal diameter of the cup cavity expands in response to an applied pressure to the distal end.
