An alloy used in restorative dentistry that contains mercury, silver, tin, copper, and possibly zinc.
A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
Any waste product generated by a dental office, surgery, clinic, or laboratory including amalgams, saliva, and rinse water.

Mercury poisoning, also known as hydrargyria, is a type of metal toxicity caused by exposure to excessive levels of mercury, leading to harmful effects on the nervous system, kidneys, and other organs, often resulting from improper handling or ingestion of mercury-containing substances.
Laws and regulations pertaining to the field of dentistry, proposed for enactment or recently enacted by a legislative body.

##### Not a valid request: I'm sorry for any confusion, but "Maine" is a state in the northeastern United States and not a medical term or condition with a specific definition in the healthcare context.
Neurologic disorders associated with exposure to inorganic and organic forms of MERCURY. Acute intoxication may be associated with gastrointestinal disturbances, mental status changes, and PARAPARESIS. Chronic exposure to inorganic mercury usually occurs in industrial workers, and manifests as mental confusion, prominent behavioral changes (including psychosis), DYSKINESIAS, and NEURITIS. Alkyl mercury poisoning may occur through ingestion of contaminated seafood or grain, and its characteristic features include POLYNEUROPATHY; ATAXIA; vision loss; NYSTAGMUS, PATHOLOGIC; and DEAFNESS.
