Confirmation of No Neurological Effects From Dental Amalgams
Neurotoxicology. 2005 Mar;26(2):241-55.
Amalgam exposure and neurological function. Kingman A, Albers JW, Arezzo JC, Garabrant DH, Michalek JE. Division of Clinical Research and Health Promotion, National Institute of Dental and Craniofacial Research, National Institutes of Health, 45 Center Drive, Room 4As-25U, Bethesda, MD 20892-6401, USA. Concerns regarding the safety of silver-mercury amalgam fillings continue to be raised in the absence of any direct evidence of harm. The widespread population exposure to amalgam mandated that a thorough investigation be conducted of its potential effects on the nervous system. The National Institute of Dental and Craniofacial Research and U.S. Air Force investigators collaborated in the ongoing Air Force Health Study (AFHS) of Vietnam era veterans. The primary study question involved adverse health effects associated with exposure to herbicides or dioxin. An assessment of exposure to dental amalgam fillings was added to the 1997-1998 health examination to investigate possible associations between amalgam exposure and neurological abnormalities. Our study population consisted of 1663 dentate AFHS participants, comprised of 986 AFHS controls and 677 Ranch Hand veterans who were exposed to dioxin in Vietnam. Two hundred and fifty-two of the participants had confirmed diabetes mellitus. Study outcomes included clinical neurological signs, vibrotactile thresholds, and summary variables for different levels of peripheral neuropathy. A limitation of our study is that our database did not include more sensitive continuous measures such as nerve conduction studies. No significant associations were found between amalgam exposure and clinical neurological signs of abnormal tremor, coordination, station or gait, strength, sensation, or muscle stretch reflexes or for any level of peripheral neuropathy among our study participants. A statistically significant association was detected between amalgam exposure and the continuous vibrotactile sensation response for the combined non-diabetic participants and separately for non-diabetic AFHS controls. No significant association in this measure was detectable for non-diabetic Ranch Hand veterans or among the combined diabetic participants. The association is a sub-clinical finding that was not associated with symptoms, clinically evident signs of neuropathy, or any functional impairment. Overall, we found no association between amalgam exposure and neurological signs or clinically evident peripheral neuropathy. Our findings do not support the hypothesis that exposure to amalgam produces adverse, clinically evident neurological effects. |

Lorscheider FL, Vimy MJ, Summers AO Department of Medical Physiology, Faculty of Medicine, University of Calgary,Alberta, Canada.For more than 160 years dentistry has used silver amalgam, which containsapproximately 50% Hg metal, as the preferred tooth filling material. During thepast decade medical research has demonstrated that this Hg is continuouslyreleased as vapor into mouth air; then it is inhaled, absorbed into bodytissues, oxidized to ionic Hg, and finally covalently bound to cell proteins.Animal and human experiments demonstrate that the uptake, tissue distribution,and excretion of amalgam Hg is significant, and that dental amalgam is themajor contributing source to Hg body burden in humans. Current research on thepathophysiological effects of amalgam Hg has focused upon the immune system,renal system, oral and intestinal bacteria, reproductive system, and thecentral nervous system. Research evidence does not support the notion ofamalgam safety.Publication Types: Review Review, tutorial Comments: Comment in: FASEB J 1995 Nov;9(14):1499-500 PMID: 7737458, UI: 95255604 http://emporium.turnpike.net/P/PDHA/mercury/asr.htm http://www.home.earthlink.net/~berniew1/index.html http://www.home.earthlink.net/~berniew1/fetaln.html http://groups.google.com/group/sci.m...14c0092?hl=en& http://groups.google.com/group/sci.m...dea93cb?hl=en& http://www.safeminds.org/ Breakthrough Research: New Study Shows Vaccine Mercury Results In More Than Twice As Much Mercury Being Trapped In The Brain **Synopsis** SafeMinds challenges IOM to back up words with actions - demands release of all documents on connection between thimerosal and autism IOM Statement Dr. Boyd Haley's Response SafeMinds Response to California Autism Prevalence Data Release of January 2005 from the California Department of Developmental Disabilities Services (January 18, 2005) "Generation Zero" - SafeMinds Analysis of Verstraeten's Original Papers Finds There is a Relative Risk of 11X times compared to the Zero Mercury Exposure Group! **Synopsis** **Presentation** (November, 2004) SafeMinds Demonstrates Urgency of Autism Epidemic in New Study **View the Study** SafeMinds Invited to Present at Institute of Medicine Data Sharing Committee Hearing **View the presentation** Written submission to Subcommittee Labor, Health, and Human Services, Education and Related Agencies, Committee on Appropriations, U.S. House of Representatives, October 5, 2004, Hearing, "Influenza Vaccine" SafeMinds Presents Evidence Exposing Vaccine-Autism Link at 09/08/04 Congressional Hearing (Announcement) Testimony of Lyn Redwood, RN, MSN, President of SafeMinds Before the Subcommittee on Human Rights and Wellness Committee on Government Reform - U.S. House of Representatives, September 8, 2004 - Hearing: "Truth Revealed: New Scientific Discoveries Regarding Mercury in Medicine and Autism" Report to Congress: "A Brief Analysis of Recent Efforts in Medical Mercury Induced Neurological and Autism Spectrum Disorders" - September 8, 2004 HTML Version Word Version Joint Statement Regarding The IOM Committee Reviewing the Vaccine Safety Datalink Project SafeMinds Statement Regarding The IOM Committee Reviewing the Vaccine Safety Datalink Project (Sally Bernard, Executive Director) Is Thimerosal the Missing Link to Autism and Development Problems?

wrote: peripheral neuropathy. A limitation of our study is that our database did not include more sensitive continuous measures such as nerve conduction studies. This statement is consistent with the observation that experimental studies to determine whether or not the electrical potentials generated by amalgam fillings are able to dissipate electrical energy through the nerves in people's heads do not appear to have ever been carried out. And the assertion that amalgam is a suitable material for use in restorative dentistry is therefore being made from a position of ignorance. It has been demonstrated experimentally that metal amalgam dental fillings generate electrical potentials with magnitudes of up to 350 millivolts, see: http://www.ncbi.nlm.nih.gov/entrez/q...&dopt=Citation And the resting potential of the human neurological synapse has a magnitude of only 70 millivolts.
