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.
AMALGAM: This is the easiest material for a dentist to use and the most common. It is the fastest and least costly choice. Amalgam is a mixture of mercury, silver, tin or other metals. This kind of filling typically lasts up to 15 years or more. The continued debate on having this material in your body for that long is the danger of the presence of mercury causing other long term side effects.
