Medical Forum / General / Dentistry / October 2004Neuroligical Effects Of Mercury
A case report cited an incident wherein four adults were acutely exposed to mercury vapor resulting from the smelting of dental amalgams (Taueg et al. 1991). Initial signs of toxicity included nausea, diarrhea, dyspnea, and chest pains. Despite chelation therapy, all four patients died 11 to 24 days after initial exposure. Mercury concentrations in the house were as high as 912 µg/m3 at or within 11 to 188 days after the exposure, and postmortem blood mercury levels ranged from 58 to 369 µg/L. Historically, the triad of increased excitability, tremors, and gingivitis has been recognized as characteristic for mercury poisoning (Goyer 1991). Low-level chronic exposures to mercury may affect the peripheral nervous system resulting in polyneuropathies (reduced sensory and motor nerve function) and neuropsychological effects (visual alterations, sensory loss, stress) (ATSDR 1989); these effects correlate to tissue levels of 20 to 40 µg/g. Neuropsychological effects were also reported by Smith et al. (1970) for occupational exposure to mercury levels of > 0.1 mg/m3. Mercury concentrations below this value did not appear to cause observable effects. Kishi et al. (1993) reported that neurobehavioral and motor function effects persisted in ex-mercury miners more than 10 years after cessation of exposure. Mercury vapor from dental amalgams has been identified as a major source of exposure to inorganic mercury in the general population (WHO 1991). An average mercury dose from dental amalgams has been estimated to be only 4 to 5 µg (Halbach 1995). 1. Central nervous system and kidneys: Both the central nervous system and kidneys are affected by inorganic mercury. The toxic effects may occur with acute, subchronic, or chronic exposure depending on the exposure level and the resulting body burden of mercury. Animal data suggest that the renal effects may be immunologically mediated. The central nervous system, especially during prenatal and postnatal development, is the primary target organ for methyl mercury. 3.4.2.1. Primary Target Organ(s)1. Central nervous system and peripheral nervous system: The critical target organs for inhalation exposure to elemental mercury vapor are the central nervous system and the peripheral nervous system.

Curiosity got the best of me. Search for holistic dentists gives some small clues as to what they practice. The totality of the human body. Too much to read, and some is repititous of Acupuncture, invisalign etc etc etc. minimally invasive treatment. Anything different in their approach. Who knows. Too much to wade through. The only thing I ask of dentistry for now, is it too much to ask that composites be a little stronger than cardboard. Gail >Curiosity got the best of me.

Many of our allopathic treatments and allopathic medicines have origins in folk medicine and in alternative medicine.

When I do use an SE adhesive (and I do frequently...deep restorations, pedo, and places where I'm worried about gingival bleeding) I have been using Clearfil SE Bond. Bond 1 has a proven, long term history of success. It's also fast and easy to use. I am not ready to abandon its use quite yet. The problem is that you can't tell (for sure) how a certain new bonding agent will perform over time until you watch it. A couple of more years should give a pretty reliable idea of performance.

They were being paid to handle amalgam waste and send it to a recycler, but got greedy (and stupid). They heated the amalgam on an open cooking utensil in the house. they thought they could extract the silver from the amalgam that way. They were right, but the high heat (very HOT) vaporized enough Hg to kill 3-4 people in the room. This was about 400 degrees Fahrenheit. Signature~+--~+--~+--~+--~+-- Stephen Mancuso, D.D.S.
