A method for producing a mouthpiece toothbrush is provided, in which at least one dental arch of the patient for whom the toothbrush is intended is scanned to generate scan data, or an impression of the dental arch is made. Based on the scan data or the then digitised impression, the dental arch space occupied by the dental arch is recorded. A bristle space is constructed around the at least one dental arch, and a toothbrush moulded piece is calculated, the surface of which facing the dental arch is determined by the dental arch space plus the bristle space. The surface is covered with a bristle carpet.

Provided are methods for collecting saliva from the oral cavity of a mammal comprising: placing a mouthpiece of a device comprising the mouthpiece in the oral cavity of a mammal, the mouthpiece comprising a chamber defined by front and rear inner walls and a base inner wall of the mouthpiece, each of the front and rear inner walls of the chamber comprising a plurality of openings, and a switch disposed in the mouthpiece; and the device further comprising a saliva collection reservoir, a fluid supply reservoir, a pump, and means for directing fluid through said device; activating the switch disposed in the mouthpiece to pump saliva from the oral cavity to the saliva collection reservoir for collection; deactivating the pumping of saliva to the saliva collection reservoir; and subsequently pumping fluid from the fluid supply reservoir to the mouthpiece for cleaning or treatment of the oral cavity.

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.

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.

The present invention relates to a mouth cleaning device using incoming fluid, a mouth cleaning system comprising such device and a method for using the mouth cleaning device. The mouth cleaning device comprises: a housing extending in a longitudinal direction comprising: an incoming fluid inlet; an outgoing fluid outlet; a cleaning head with an incoming fluid outlet and an outgoing fluid inlet; and a cleaning head connector configured for connecting the cleaning head to the housing, and the cleaning head connector comprising an incoming fluid channel configured for operatively connecting the incoming fluid inlet and incoming fluid outlet, and an outgoing fluid channel configured for operatively connecting the outgoing fluid inlet and outgoing fluid outlet, wherein the cleaning head connector comprises an incoming fluid connection and an outgoing fluid connection that are provided at a connection distance in the longitudinal direction of the housing.

A dental suction device for suction of fluid deflections and aerosols produced by the effect of a drill or laser of a dental instrument inside the oral cavity, and attachment for removably attaching the dental suction device to the dental instrument, characterised in that the dental suction devices comprises a tubular body for suctioning fluid that forms a first outer cavity to receive a working head of the dental instrument, wherein a distal portion (B) of the tubular body extends radially so as to at least partially surround a perimeter of the first outer cavity housing the working head of the dental instrument, wherein a wall of the distal portion (B) of the tubular body incorporates at least one suction orifice.

Embodiments of this disclosure provide a staging assembly (10) for negative pressure, multi-canal irrigation of a root canal system followed by obturation. The staging assembly may be part of a kit that includes a plurality of catheters (50) sized for insertion into the root canal system. To hold the catheter in its proper position in the canal, the catheter may include a stop (37) and the staging assembly may include a corresponding stop hold (36). The distal end (51) of the catheter can be positioned 2 mm to 5 mm from the terminus end of the root canal. The staging assembly is then sealed, creating a closed system. Irrigating solution is vacuum-drawn out the ends of the catheters and debris is evacuated through a vacuum port of the stating assembly. During irrigation, no hands on time is required by the clinician. After irrigation, vacuum is reversed to dry the canal. Obturation occurs through the vacuum portion.

A method for continuously evaluating the effectiveness of debridement of a root canal of a tooth, the tooth having an open access cavity and an apex end, includes delivering a fluid to the open access cavity of the tooth, evacuating the fluid near the apex end of the tooth such that the fluid flushes most of the root canal before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris, a concentration level of the debris, or a type of the debris. An apparatus for use in debriding a root canal of a tooth includes a microcannula or a macrocannula configured to evacuate a fluid in the root canal, and a sensing mechanism fluidically coupled to the microcannula or the macrocannula, the sensing mechanism configured to continuously sense debris in the evacuated fluid in real time.

A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user's suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

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.
