This study reveals that there is a positive correlation between blood mercury levels and oral tissue response in mother rats, however, the negative impact of mercury on oral tissues of offspring rats was due to high mercury levels in their mothers' blood during pregnancy. Further clinical studies are recommended to test our findings in man.
Biomonitoring studies show that humans carry a body burden of multiple classes of contaminants which are not often studied together. Many of these chemicals may be hepatotoxic. We used the 2003–2004 National Health and Nutrition Examination Survey to evaluate the relationship between alanine aminotransferase (ALT) a sensitive indicator of liver cell injury, and 37 environmental contaminants, comprising heavy metals, non dioxin-like polychlorinated biphenyls (PCBs), and dioxin-like compounds.
In 1997 The Environmental Protection Agency compiled the Mercury Study Report to Congress. This document covers the human health effects of mercury and mercury compounds. Upon reading the symptoms of mercury vapor-induced neurotoxicity and the toxicokinetics, it is apparent that mercury has great potential to mimmic symptoms of dementia and Alzheimer's disease.
This paper, written by Mats Hanson, examines studies from leading research institutes around the world. His research reveals that there has been a documented trend in positive health changes after removal of amalgam fillings since as far back as 1986 (at least!)
This article explorers the statistics concerning long term nicotine gum chewing and determines if chewing nicotine gum can elevate the levels of mercury released into the body from amalgam fillings.
The concept of accumulative micro-mercurial neurotoxicity with specific reference to dental amalgam, has been well documented and prolonged exposure to mercury has been associated with the unique lesions of the AD brain. Therefore, amalgam, as the largest source of mercury vapor in the general population, should be included in the differential diagnosis of patients being investigated for neuro-psychiatric problems and shortterm memory loss.
In the present study we describe a strong, positive correlation between mercury exposure from dental amalgam fillings and urinary mercury excretion over a 7-year longitudinal course of amalgam treatment in children. These findings are relevant within the context of children’s health risk assessment and suggest directions for future research to determine whether differential sensitivities to mercury between boys and girls do exist.
Silver amalgam specimens treated with 10% carbamide peroxide bleaching agents produced a statistically significant increase in the quantity of Hg released after 15 days compared with the control group. Additional studies are needed to assess the impact of this increase. However, the authors recommend avoiding the indiscriminate exposure of silver amalgam restorations to carbamide peroxide bleaching agents.
Stephen M. Koral, DMD, FIAOMT writes an un-biased article that looks into commonly accepted variables concerning exposure, toxicology and risk assessment in the use of amalgam fillings in dentistry and the effect it will have on the use of amalgam in the future.
Inhalation experiments in rats and primates show deposition of Hg in spinal cord following single high-dose short-time exposure. Mercury accumulation in anterior horn cells is followed by axonal atrophy and distal weakness similar to the clinical picture in human ALS. Respiratory Hg exposure could contribute to elevated concentrations of Hg found in cerebrospinal fluid from patients with ALS.
Mercuryexposure.info was created and is maintained by consumers injured from exposure to mercury vapor and particles released by their dental amalgam fillings during placement, polishing, removal and day to day use. We are dedicated to providing accurate, up to date information on the many facets of dental mercury amalgam fillings.
