An oral irrigator includes a base having a pump mechanism, a reservoir housed within the base and fluidically connected with the pump mechanism. A handle with a jet tip is connected with an outlet from the pump mechanism to receive a pressurized fluid stream from the reservoir to direct a fluid at a surface inside an oral cavity. The oral irrigator also includes a radiant energy source and delivery system for directing radiant energy at a surface inside an oral cavity.

According to various implementations, a dental cleaning device includes a steam conduit and a cooling fluid conduit. The steam conduit has a distal tip with an opening defined therein that allows steam to be applied intraorally close to a dental implant to flush away bacteria that has colonized on or adjacent the dental implant. The cooling fluid conduit has a distal tip with an opening defined therein that allows a cooling fluid to be applied intraorally close to the dental implant following the application of the steam to cool the tissue and prevent overheating of the tissue and bone adjacent the dental implant. For example, the cooling fluid may be applied intermittently with the steam, or the cooling fluid may be applied continuously while the steam is applied intermittently, according to various implementations.

A compact oral hygiene device comprises a unique mini constant jet pump which integrated with a motor, has three diaphragm chambers, draws the fluid from a reservoir and propels fluid out from a buffer room to tips at constant pulseless, high efficiencies and low noise; and a plurality of exchangeable tips cleanses teeth and the interdental area.

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.

A tip assembly for use with a dental tool, the tip assembly comprising a housing for attaching to the dental tool, at least one aspiration needle having a passageway extending at least partially through the aspiration needle, a substantial length of the aspiration needle, or at least from one end to the other end of the aspiration needle, the passageway providing a single continuous path to aspirate the irrigant and/or debris from the root canal cavity of the tooth, and at least one irrigation needle having a passageway extending at least partially through the irrigation needle, a substantial length of the irrigation needle, or at least from one end to the other end of the irrigation needle, the passageway provides a continuous flow path for delivering fluid/irrigant from a reservoir in communication with a proximal end of the irrigation needle to the distal end of the irrigation needle and into a root canal/coronal opening of a tooth.

Various apparatus and methods for cleaning teeth and gingival pockets are disclosed herein. A fluid platform can include a pressure wave generator configured to propagate pressure waves through a treatment fluid. The pressure waves may be sufficient to remove undesirable dental deposits from a treatment tooth, neighboring gums, and/or spaces between the tooth and gums.

A dental irrigator with stepless speed regulation includes a dental irrigator body; a nozzle; a stepless speed regulation component; the dental irrigator body includes a water storage chamber and a movement component embedded in the side of the water storage chamber; the movement component is used to extract water from the water storage chamber; the nozzle is arranged on the top of the movement component, and the nozzle has a water outlet pipe communicated with the movement component for teeth cleaning; the stepless speed regulation component includes an adjustment member rotatably connected to the top of the movement component, an adjustment control panel that controls the working state of the nozzle, and a transmission mechanism installed between the adjustment member and the adjustment control panel; the adjustment member drives the transmission mechanism to control the adjustment control panel to adjust the water outlet rate in the nozzle.

Disclosed is an irrigation needle including an active part extending between a first end intended to be connected to an irrigation device and a second closed end, a central channel extending inside the active part and open at the first end and at least one opening arranged radially on the active part in the vicinity of the second end and communicating with the central channel for distributing an irrigation solution. The needle is obtained as one piece using a thermoplastic micro-injection moulding method.
