A dental water jet is provided. The dental water jet may include a base unit, a reservoir supported by the base unit, a handle supported by the base unit, and a container covering an opening of the reservoir. The container may include a base supported by the reservoir and a lid movable relative to the base. The container may be configured to store one or more tips for use with the handle.

An apparatus for endodontic treatment, comprising: a nozzle connected to a fluid source comprising: a tip small enough to be inserted into a pulp chamber of a tooth; an inner geometry which forms a flow parameters including non-axial flow direction of nozzle fluid flowing through the inner geometry such that discharge fluid discharged from the inner geometry increase rotation of root canal fluid within a root canal sufficiently to remove tissue from the root canal.

A personal hygiene implement comprises an axle that extends along a first longitudinal axis; a movable functional element comprising a base comprising a first side and an opposing second side, a first pillar extending from the first side of the base, wherein the first pillar comprises a piston chamber that is fluidly connected to a discharging through-hole, and at least one cleaning element extending from the second side of the base; and a fixation element comprising a piston which extends orthogonally to the first longitudinal axis; wherein the movable functional element is capable of rotatably oscillating around the axle, and the piston chamber engages with the piston to form a pump.

A dental treatment system can include a console, a tooth coupler, and an interface member that provides at least one of fluidic, electrical, mechanical, and data communication between the tooth coupler and the console. The tooth coupler (which may comprise a handpiece or a treatment cap) can act as a working end of the system to administer a suitable treatment procedure, such as a cleaning procedure, an obturation procedure, a restoration procedure, etc. The tooth coupler can removably engage the interface member such that the clinician can easily engage and disengage the tooth coupler and interface member.

An oral irrigator including a fluid reservoir, a pumping assembly, a pressure control assembly, and a nozzle. The pumping assembly comprises a power source, a motor in electrical communication with the power source, and a pump in fluid communication with the reservoir. The pressure control assembly is in fluid communication with the pump; mechanically varies a pressure of a fluid exiting the nozzle to change the outlet pressure of the oral irrigator a high pressure to a low pressure and vice versa.

Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.

A oral irrigator device (10) for cleaning teeth, including a system (14) for producing a stream of liquid/air bursts and a nozzle (16) connected to the system, and through which the stream of liquid/air bursts are directed. The nozzle can include a guidance tip (26) including a base portion (30), a tip portion (28), and an orifice (31) through which the stream of liquid/air bursts exits at a flow output pattern, and a flow output pattern selection mechanism (90, 90′) connected to or positioned within the guidance tip. A flow output pattern selection mechanism can be configured to be selectively actuated and to vary, upon the actuation the flow output pattern between a first flow output pattern to at least a second flow output pattern.
