A classification first published in 1993, that has been adopted as a consensus definition, identifies StevensâJohnson syndrome, toxic epidermal necrolysis, and SJS/TEN overlap. All three are part of a spectrum of severe cutaneous reactions (SCAR) which affect skin and mucous membranes.
Approximately half of a dental amalgam filling is liquid mercury and the other half is a powdered alloy of silver, tin, and copper. Mercury is used to bind the alloy particles together into a strong, durable, and solid filling.he form of mercury associated with dental amalgam is elemental mercury, which releases mercury vapor. The form of mercury found in fish is methylmercury, a type of organic mercury. Mercury vapor is mainly absorbed by the lungs. Methylmercury is mainly absorbed through the digestive tract.
The side effects of amalgam and the toxicity of amalgam are primarily caused by the presence of large amounts of mercury in the fillings. Approximately eighty percent of the invisible mercury vapor coming off the surface of the fillings penetrates the skin (called mucosa) in your mouth and enters your body.opper can have toxic side effects. Some people can have allergic reactions to the metals, including mercury. The combination mixture of all the metals in the filling material can also create electric currents when bathed in saliva. Electric currents occur because the fillings behave just like a battery.
