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.

A dental evacuation tip has a body defining an interior passageway extending along a length of the body, and proximal and distal openings to the interior passageway. The proximal and distal openings are spaced apart from one another along the length of the body. The dental evacuation tip is configured so that a mirror apparatus can be removably connected to the dental evacuation tip so that at least a portion of a rod of the mirror apparatus is positioned in the interior passageway and a mirror of the mirror apparatus is proximate the distal opening.

The present invention provides an apparatus adapted for ejection of material, e.g., saliva, from the mouth of a patient during a dental procedure. The apparatus has at least two distal openings such that material may be ejected simultaneously from at least two locations within the patient's mouth. The invention provides a suction apparatus having a proximal tube, which may couple with a standard waste container apparatus having a suction source.

An injection molded oral care device includes a neck portion and a handle coupled to a first end of the neck portion. where the handle has one or more grips configured to facilitate gripping the oral care device. The oral care device also includes a cleaning head coupled to a second end of the neck portion. The cleaning head includes a base and one or more bristles extending from the base, where the one or more bristles are configured to facilitate cleaning an oral cavity of a patient. The neck portion, handle, and base of the cleaning head are formed by injection molding a first material, and the one or more bristles are formed by injection molding a second material, different from the first material.

A disposable apparatus including: (a) a mirror holder including a floor with a raised circumferential edge having a height(Height of a support base+thickness of the mirror); (b) three or more deformable posts distributed around an inner side of said circumferential edge; (c) a plurality of said support bases, each of said bases adjacent to one of said posts on an inner side of the post; and (d) a suction tube with a mouth spanning a plane of a mirror positioned on said bases and a rear opening across said tube from said mouth. Related apparatus and methods are also disclosed.

An oral cavity cleaner according to an embodiment of the present disclosure includes: a handle including an inflow path through which washing water flows and a discharge flow path through which contaminated water sucked from an oral cavity flows; a mouthpiece configured to spray the washing water supplied through the handle into the oral cavity; and a core suction part having an edge surrounded by the mouthpiece, the core suction part being configured to suck the contaminated water that has been discharged from the mouthpiece and washed teeth.

A oral suction device that incorporates a foldable suction body, a bite block and a suction adapter that is utilized to block the throat cavity. The body draws water, saliva and debris from about a gap along its outer perimeter. The suction body resides in a vertical position in the patient's mouth and is able to expand to allow the transport of large pieces of debris without coming apart. There is a fishtail section of the suction body that anchors it between the teeth and the inner cheek so as to allow the remained of the suction body to block the throat hole.
