Oral Metal Exposures from Dental Materials and Oral Effects Exposure to metals has been found to be one of the most common causes of allergic contact diseases (ACD) and other allergic and immune reac ve condi ons. Having dissimilar metals in the teeth, e.g. amalgam (mercury, copper, n, silver), gold alloys (gold, palladium), nickel or stainless steel crowns (nickel, cobalt), causes galvanic electrical currents and much higher mercury vapor levels in oral air and metal levels in oral ssues. For those with amalgam dental fillings, exposure from fillings amounts to 50 to 90 % of exposure, with the average being about 75 % of total exposure. Mercury is an unusual metal because it is commonly a liquid at room temperature and vaporizes to a gas from its liquid or solid states. Studies found that mercury amalgams are unstable due to mercury's vaporiza on and galvanic ac on, leaking mercury vapor con nuously into the lungs and saliva at levels exceeding government health standards. The other most common sources of mercury exposure are methyl-mercury from fish or mercury thimerosal from vaccines, which is a major source of exposure mostly for infants or those frequently receiving flu shots. The amount of mercury released into saliva has been found by large studies to be about 1.5 to 1.9 micrograms per liter for each addi onal amalgam filling. Average mercury levels in gum ssue near amalgam fillings are over 100 ppm and are the result of mercury flow into the mucous membrane because galvanic currents with the mucous membrane serve as cathodes (nega vely charged electrode) and amalgam metals serve as anodes (posi ve charged electrode). Concentra ons of mercury in oral mucosa for a popula on of pa ents with 6 or more amalgam fillings taken during oral surgery were 20 mes the level of controls. Amalgam also releases significant amounts of silver, n, and copper, which also have toxic effects, with organic n compounds formed in the body being even more neurotoxic than organic mercury. The high levels of accumulated mercury also are dispersed to other parts of the body. Some studies have also found persons with chronic exposure to electromagne c fields (EMF) to have higher levels of mercury exposure and Abby's Magazine - Volume 5 Issue 6| Page 45 Located in Abby's Health And Nutrition 14374 N.
