An oral fluid delivery device is described. The device includes a housing forming at least one cavity. The cavity includes at least two reservoirs, a first reservoir and a second reservoir. The device also includes an elongated neck with a distal end having at least one distal opening for passage of a fluid, a proximal end, and a channel fluidly connected to the distal opening. The device also includes a cap at the proximal end of the elongated neck. The cap includes at least one aperture aligned with the channel of the elongated neck and is rotatably coupled to the housing such that rotating the cap relative to the housing selectively aligns the aperture with a first reservoir opening to provide fluid communication between the first reservoir and the channel, or aligns the aperture with a second reservoir opening to provide fluid communication between the second reservoir and the channel.

This invention relates to a negative pressure irrigation system including one or more negative pressure irrigation needles sized for insertion into a canal of a tooth, each needle having a closed distal end and two suction inlet ports located opposite one another immediately proximal to the closed distal end. The needles are placed in communication with a dental vacuum system by way of a suction manifold. An irrigant inlet tube supplies irrigant from an irrigant container into a pulp chamber or a tooth. The irrigant inlet tube may include a tapered end designed to tightly fit into a lateral irrigant supply port previously drilled into the pulp chamber. A light-cure polymer seals the inlet tube and needles when in use.

The present disclosure provides an oral hygiene device member capable of further reducing a burden on a target object in an oral cavity and capable of maintaining a cleaner state while suppressing deterioration in cleaning performance. Oral hygiene device member according to the present disclosure comprises handle having flow path through which liquid is allowed to pass. Oral hygiene device member comprises head comprising: head body connected to one end side of handle; and head material held by head body. Head material comprises a cleaning part. The cleaning part is exposed from the head body in a state of being held by the head body. The cleaning part is formed of fibers that clean a target object in an oral cavity. Liquid supply path is formed in the head. The liquid supply path communicates with the flow path and supplies liquid to the cleaning part.

A periodontal cleaning device, including a cleaning head having a fluid outlet for releasing a cleaning fluid and a suction member for suction of a waste fluid, a cleaning fluid source, connected to the fluid outlet, a controllable suction device connected to the suction member, fluid feeding device for controlling a flow of the cleaning fluid from the cleaning fluid source to the fluid outlet. The periodontal cleaning device further has a control unit, arranged for controlling the controllable suction device in generating a vacuum pulse in the suction member, controlling controllable fluid feeding device in generating a fluid flow pulse in the fluid outlet in response to the vacuum pulse, and controlling the controllable suction device in generating a subsequent vacuum pulse in the suction member, and introducing a time period between the cleaning fluid flow pulse and the subsequent vacuum pulse in the suction member.

A toothbrush system configured to be coupled to an external suction source. The toothbrush system includes a shaft with a main body with a first end and a second end, and a bristle array and a suction port arranged at the second end. The bristle array and the suction port both extend away from the shaft so that an opening of the suction port is proximal to a distal end of the bristle array. The shaft also includes a stem arranged at the first end. The stem includes a passageway that extends through the main body to provide a fluid connection to the suction port, and is configured to be coupled to the external suction source. Also, the handle is removably coupled to the shaft and includes a drive system operably coupled to the bristle array to actuate motion of the bristle array.

This disclosure relates to an oral care appliance and a method for use in oral care for cleaning the teeth of one or two arches using a mouthpiece forming a closed or nearly closed cavity. The mouthpiece is adapted to deform in response to pressure variations inside the cavity and create an action on the teeth. This disclosure includes a description of depression chambers and associated methods that can contribute to the operation of the oral care appliance by affecting the aforementioned pressure variations.

Methods, apparatus, and systems for reducing transmission of aerosol droplets in a medical or dental procedure are described. One protective shield system includes a base plate, a shield having at least one transparent section, and a pipe or conduit comprising a plurality of holes thereon. The shield is configured to be removably attached to the base plate to allow attachment of the shield to the base plate prior to the medical or dental procedure and removal of the shield from the base plate after the medical or dental procedure. The pipe or conduit is positioned adjacent to an inner surface of the shield and on at least part of a perimeter of the shield. The pipe includes an end that is configured to connect to a suction system to enable removal of the aerosolized particles from below the shield during the medical or dental procedure.

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 tool includes: a hand piece; an endodontic hand file; a stopper, wherein the stopper comprises a first hole for receiving a portion of the endodontic hand file; and a mechanical motion module that imparts mechanical motion to the endodontic hand file. A dental system includes: a hand piece; an endodontic file; and a stopper comprising at least two holes, wherein a first hole receives a portion of the endodontic file, and wherein a second hole receives a portion of a first tube for delivering a liquid to the endodontic file. The dental system can further include a second tube partially contained in a third hole of the stopper for suctioning liquids from a patient's mouth. The dental system can also further include a mechanical motion module.
