Compositions and methods useful for removing anionic contaminates and debris including phosphates from dental restorative substrates are disclosed.

Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

The present application provides an oral irrigator which includes an irrigator body. The irrigator body includes a water tank, a nozzle, and a cathode plate and an anode plate are provided spaced apart from each other at a bottom of the water tank. The anode plate and the anode plate are electrically connected to a negative electrode and a positive electrode of a power supply component of the oral irrigator, respectively. A water outlet of the water tank is located at the bottom of the water tank. Water in the water tank is electrolyzed by the cathode plate and the anode plate to generate ozone water and hydrogen-rich water, and flow out from the water outlet to the nozzle of the irrigator body to be sprayed out, aiming to solve a problem that the existing oral irrigator only uses water flow for physical cleaning.

The present application relates to the field of oral care products, and more particularly to an oral irrigator. The oral irrigator comprises: an irrigator body, and a generator arranged inside the irrigator body. The irrigator body comprises: a water tank, a nozzle, and a driving assembly. The water tank is configured to accommodate an electrolyte. The generator is configured to electrolyze the electrolyte to generate ozone water and hydrogen-rich water. The electrolyte of the water tank is driven by the driving assembly to enter the generator, electrolyzed in the generator, such that a resulting electrolyzed ozone water and hydrogen-rich water are sprayed out from the nozzle of the irrigator body. In this way, it is solved the technical problem that the existing oral irrigator only uses a water flow for physical cleaning.

A dental apparatus is disclosed. The dental apparatus can comprise a pressure wave generator to be disposed at a treatment region of a tooth. The pressure wave generator can include an opening to deliver a flowable filling material to the treatment region. The apparatus can include a reservoir for supplying the filling material to the pressure wave generator. The pressure wave generator can be configured to generate pressure waves through the treatment region to cause the filling material to substantially fill the treatment region.

The present invention relates to oral care. In order to improve the effectiveness of a flossing device, an interdental space detection component is proposed for detecting an interdental space. The interdental space detection component may be integrated in a brush head with integrated flossing function. The fluidic flossing function may selectively be switched on at the interdental space, thereby saving flossing fluid and preventing ineffective flossing outside the interdental space.
