Oral hygiene systems and methods for their use are provided. An oral hygiene system includes a mouthpiece having an outer portion and an inner portion configured to receive at least a portion of a user's dental and gum structures, a plurality of filaments disposed within the inner portion of the mouthpiece, a water pressure irrigator configured to be selectively coupled to the outer portion of the mouthpiece and to deliver fluid to the inner portion of the mouthpiece, and a fluid reservoir in fluid communication with the water pressure irrigator and configured to deliver the fluid thereto, wherein the system is configured to generate ultrasound/ultrasonic vibration within the inner portion of the mouthpiece.

This invention relates to a coolant for cooling a device for use in dentistry, the coolant comprising a Newtonian fluid having a viscosity greater than water. The invention also relates to a method of cooling a device for use in dentistry utilising the coolant, the coolant for use in a method of cooling a device for use in dentistry and an apparatus and kit comprising the coolant.

A composition delivery source (200) is provided that includes (a) a chamber (202), which is shaped so as to define (A) one or more liquid ports (310) in fluid communication with an interior of the chamber (202), and (B) one or more solid-liquid composition ports (312) in fluid communication with the interior of the chamber (202); (b) a solid-liquid composition delivery tube (314) in fluid communication with at least one of the one or more solid-liquid composition ports (312); (c) a mixing tube (316) in fluid communication with at least one of the one or more liquid ports (310) and at least one of the one or more solid-liquid composition ports (312); and (d) a liquid-supply tube (318) in fluid communication with at least one of the one or more liquid ports (310). A pump unit (201) includes one or more pumps (223), which are arranged to cause flow in the mixing tube (316) during a mixing activation state (342), and to cause flow in the liquid-supply tube (318) during a particle-delivery activation state (344).

An oral rinsing apparatus that washes away plaque, bacteria, and food debris that might reside on the teeth and along the gumline includes a handle, a nozzle, and a water supply line. The handle is adjacently attached to the nozzle. The water supply line that is connected to the handle and positioned opposite to the nozzle. The water supply line is in fluid communication with an existing water source diverter and provides a stream of water into the handle and the nozzle. The stream of water then flows through a first channel of the handle and a second channel of the nozzle before discharges through a head of the nozzle. A flow-activation button of the handle turns on and off the stream of water that exits through the head as a plurality of flow control settings are integrated into the head.

A removable fluid connection fitting for an oral irrigator is provided. The oral irrigator may include a base unit including an opening formed therein, an oral irrigator handle including a handle inlet, a fitting removably coupled to the base unit and seated within the opening formed in the base unit, and a tube in fluid communication with the fitting and the handle inlet. The fitting may include a fitting inlet and a fitting outlet, the fitting inlet being in fluid communication with the base unit. The tube may be in fluid communication with the fluid outlet. Fluid from the base unit may flow through the fitting inlet, to the fitting outlet, into the tube, and into the handle inlet.

Method for treating a service water supply unit of a dental treatment unit, wherein the method has the following sequence of treatment steps: cleaning the service water supply unit using a cleaning agent, preferably a cleaning liquid or a cleaning foam; disinfecting the service water supply unit using a disinfecting agent, preferably a disinfecting liquid.

A composition for reducing/eliminating aerosolization during dental/surgical irrigation procedures comprising at least one liquid or solid carrier and at least one polymer, wherein the at least one polymer comprises at least hydroxyalkyl cellulose polymer, at least one poly(ethylene oxide) polymer or a mixture thereof and wherein the at least one polymer is not soluble in the liquid carrier.

A coupling device for selectively coupling a dental handpiece to a dental base station. An electrical power source is housed by the coupling device. A first end of the coupling device is selectively coupleable to the dental base station and configured to receive a gaseous or fluid medium from the dental base station. A second end of the coupling device is selectively coupleable to the dental handpiece and configured to output the gaseous or fluid medium from the dental base station to the dental handpiece and to output electrical power from the electrical power source to the dental handpiece.

Handpiece (1) for endodontic treatment, characterized in that it comprises an irrigation device for conveying an irrigation solution from a reservoir (10) to a head (5) for the purpose of ejecting the solution into a root canal, and in that it comprises an agitator device for setting in motion an endpiece (2) intended to penetrate inside a root canal in order to promote the action of the irrigation solution.

A heat sterizable, independent dental water supply apparatus has a hand piece control head and a water supply container removably connected to the control head. The apparatus in connectible with a dental, hand piece, an air source and a controller such as a dental foot pedal. In use, the apparatus supplies sterile irrigation water at the hand piece under the control of a dental practitioner. The apparatus is particularly useful of oral surgeons, prosthodontists and other dental specialists. Methods of making and using the apparatus are also disclosed.
