This disclosure relates to a device to break down biofilm and selectively supply liquid in the mouth. An examples head for a dental tool includes body, a front surface, and a back surface. The body define a chamber to contain a substance and a vacuum channel separate from the chamber to fluidly connect to a vacuum supply. The front surface includes a brush plate with brush teeth. The brush plate defines a wall of the chamber. The front surface also defines distribution holes in fluid connection with the chamber. The back surface is opposite the front surface. The back surface defines a vacuum port in fluid connection with the vacuum channel.

A saliva collection and testing system comprising an electric toothbrush (1) suitable for taking a user's saliva by way of taking means (15), and a test unit (21) for testing the taken saliva, said test unit (21) including a seat (22) for the electric toothbrush (1) comprising means (25, 33) for taking the saliva collected by the toothbrush, said test unit (21) cleaning-up the saliva taking means (15) of the electric toothbrush (1) after saliva is taken so as to prepare said electric toothbrush (1) to a subsequent use. A digital tooth fingerprint sensor is present on the toothbrush and allows to recognize the user. Advantageously the test results are sent to a remote unit via a wireless system and in an encrypted mode for their subsequent processing by one or several Machine Learning algorithms which exploit an Artificial Intelligence.

The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.

A disposable dental valve device has a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, a first partial opening formed in the valve body and a second partial opening formed in the valve body, and a movable valve sealing device adapted to being inserted into one of the partial openings, the movable valve sealing device having an opening for alignment with the lumen formed between the tip receiving end and the hose receiving end, the movable valve sealing device having a check valve positioned in the opening, and the movable valve sealing device having a top for positioning the movable valve sealing device between a closed position and an opened position.

A suction member for a high-volume evacuator (HVE) suction tool used in dental procedures. The suction member has a connection portion at a proximal end, a tubular portion connected to the connection portion, and a suction tip connected to the tubular portion at a distal end. The suction tip includes outwardly flared lobes and open-ended peripheral vent openings alternating about its circumference. The distal ends of the lobes are generally aligned in an oblique distal tangent plane inclined relative to a longitudinal axis of the tubular portion. The vent openings are spaced closer together towards a front side of the suction member, and the lobes include a widest and most flared rear lobe that is useful for soft tissue retraction.

The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.

Provided in this disclosure is a dental filter including a chair-side trap for receiving particles removed from a patient during a dental procedure. The chair-side trap includes a basin for collecting the particles from the patient. The dental filter additionally includes a filter insert sized to be received and retained in the chair-side trap, for preventing the particles to flow outside the chair-side trap. The filter insert is a fabric material including a fine micron cloth that captures particles greater than 5 microns. The filter insert also includes sealed edges around the circumference of the filter insert, where the sealed edges are formed by fusing the fabric material.

The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.

A dental waste containment system having a treatment stage to reduce the contaminant levels of the stored fluid. The treatment stage may include a settling canister disposed before the fluid storage reservoir to remove and contain at least some solid contaminants from the fluid waste before the fluid waste is moved into storage. The system may include a bypass subcircuit to allow fluid waste to selectively bypass the treatment stage. The present invention also provides a method of collecting, containing and transporting dental waste that includes separate containment of solid and fluid dental waste. The method includes at least partial separation and containment of solid contaminants in the treatment stage before the fluid dental waste is moved into separate storage. The accumulated fluid dental waste and accumulated solid waste may be separately collected from the system and separately transported to a remote facility for treatment, reclamation and/or disposal.

A filter unit for a conventional suction system of dental equipment is proposed. It consists of a disposable filter and a connecting module fixed to the suction system. The connecting module removably connects the disposable filter to the system, and includesan inlet pipe passing a water flow and solid contents from the system, an outlet pipe returning the water flow into the system, a hole communicating with the inlet pipe, a pipe projection communicating with the outlet pipe, andfixing slots. The filter includesa container collecting the solid contents, a cover including inlet and outlet holes and provided with fixing projections removably engaged with the fixing slots, anda lock-fixer rotatably mounted within the cover. It allows for removable connecting the filter to the system, which significantly improves convenience of servicing the system, safety and sanitary protection of dental personnel.
