An evacuation dam apparatus including a frame having a top frame member, a bottom frame member, and two side frame members. A working area formed by the frame, a plurality of ports adjacent the working area, an outlet fluidly coupled with the plurality of ports. A fluid flow from at least a portion of the plurality of ports to the outlet forms a fluid flow path across the working area and at least a portion of the fluid flow path is formed within the frame.

A system for removing aerosol contaminants from the air in a room is disclosed. The system comprises a vacuum inlet coupled to a vacuum system and operable to draw air from nearby into the vacuum system, filter out aerosol contaminants present in the air, and return the filtered air back into the room. The system includes airways internal to a dental chair, through which air may be drawn and filtered. The system may be used near a patient during a dental or medical procedure to remove aerosol and splatter potentially containing such contaminants as COVID-19 and other infectious diseases.

A flexible support for a dental tool includes a distal holder configured to securely hold the dental tool which may be quickly released, the flexible support includes an anchoring member configured to fit snugly within a tool recess of a tool cradle, the flexible support includes a tightener member adapted to secure the anchoring member with the tool recess.

Provided is a system and method for a dental surgical guide for placing at least one dental implant in a patient's mouth. The surgical guide is a formed prosthesis with a contour to fit upon a patient's teeth. The formed prosthesis providing; at least one guide sleeve disposed in the formed prosthesis and structured and arranged to guide a surgical tool into a patient's jaw at a predetermined location, the guide sleeve defining a tool alignment pathway; at least one irrigant port structured and arranged to receive an irrigant line from a remote irrigant source and conduct the irrigant to a spout disposed proximate to each guide sleeve. A hydraulically activated valve may also be disposed within the spout. An associated method of use is also provided.

A suction handpiece for a dental treatment unit has a negative pressure connection which can be connected with a negative pressure source of the treatment unit. A saliva connection of the suction unit can be connected with a saliva suction cannula and an atomized spray connection that can be connected with an atomized spray suction cannula. A branched flow path connects the negative pressure connection with both the saliva connection and the atomized spray connection and includes a branching section on which a negative pressure channel ending on the negative pressure connection divides into a saliva channel ending on the saliva connection and an atomized spray channel ending on the atomized spray connection. The atomized spray channel at its narrowest point has a first cross sectional area which is at least twice as large as a second cross sectional area at the narrowest point of the saliva channel.

A method for reducing toxic mercury in wastewater effluent comprises the steps of: identifying a system into which wastewater effluent is introduced, the wastewater effluent including organic compounds and organomercurial compounds; producing a treatment composition comprising a solution including a surfactant, digestive microbes suspended in the solution, and mercury-transformative microbes suspended in the solution; and providing the treatment composition into the system containing the wastewater effluent, such that the digestive microbes degrade the organic compounds in the wastewater effluent, and the mercury-transformative microbes reduce the organomercurial compounds in the wastewater effluent into nontoxic volatile elemental mercury. In certain systems for reducing toxic mercury in wastewater effluent, a biological capture medium is positioned within a vessel and configured to provide a capture point for microbes to adhere to and create biofilms. One such system is a dental evacuation system in which wastewater effluent is introduced into the system via an aspirator.

Systems, methods and components thereof for preventing ambient spread of aerosol during a cosmetic, medical or dental procedure are disclosed. The systems and methods utilize a containment unit that includes a rigid or semi-rigid transparent shield and a transparent or translucent flexible bib extending from an outer periphery of the shield. The containment unit covers a portion of a patient while still allowing a professional to view and perform a procedure on that portion of the patient. The systems and methods further utilize an inlet that is usable to facilitate evacuation of air from a confined space created by the containment unit.

A disposable dental waste filter device has a body having a tube receiving end having an outlet and a cap receiving end, a cap portion having an inlet and an end for insertion into the cap receiving end, a valve insert assembly for insertion into the body and the cap portion, and a filter assembly positioned within the body.
