Dr. Michaela McKenzie © The use of Mercury dates back to the 17th Century France was the first to use inorganic mercury in the form of mercuric nitrate to treat the fur of small animals for the manufacture of felt hats. From there it spread to England by the Huguenots. By the Victorian era the hatters' condition had become proverbial, as reflected in popular expressions like "mad as a hatter" and "hatters' shakes" Mad hatter disease, or mad hatter syndrome, is occupational chronic mercury poisoning among hatmakers whose felting work involved prolonged exposure to mercury vapours. The neurotoxic effects included tremor and the pathological shyness and irritability characteristic of erethism. Some of the steps in the manufacture of felt hats are illustrated in this image from 1858. Dr. Michaela McKenzie © Felt Hats were made using mercury Picture postcard of a hat factory in Danbury, Connecticut (postmarked 1911) A man working in hat manufacture with no protective equipment, putting him at risk for mercury poisoning Dr. Michaela McKenzie © Signs and symptoms: red fingers, red toes, red cheeks, sweating, loss of hearing, bleeding from the ears and mouth, loss of appendages such as teeth, hair, and nails, lack of coordination, poor memory, shyness, insomnia, nervousness, tremors, and dizziness. Dr. Michaela McKenzie © Minamata disease (Japanese: Ỉಛ⑓ Hepburn: Minamata-byō?), sometimes referred to as Chisso-Minamata disease (ࢳࢵࢯỈಛ⑓ Chisso-Minamata-byō?) Dr. Michaela McKenzie © Minamata Bay was heavily polluted from 1932 through 1968 by wastewater from a fertilizer company. Effects on wildlife were severe! Cats that ate the fish would develop strange body contortions -"dancing cat fever".[1] Dr. Michaela McKenzie © Minamata Disease •Minamata Disease is a disease that is caused by methyl mercury. Methly mercury is taken into our bodies by eating fish and shellfish, which are polluted by factory drainage. Symptoms of Minamata Disease • Attacks the brain and central nervous system Mercury Toxicity Causes various symptoms: • Numbness in extremities • Unsteadiness in legs and hands • Extreme fatigue • Tinnitus - ringing in ears, and/or loss of hearing • Ocular damage - narrowing field of vision • slurred speech • Ataxia – uncontrolled, awkward movements • Earlier victims: became unconscious, insane, or died a month after the symptoms started • Chronic Symptoms: migraine headaches, frequent tiredness, loss of smell and taste, and memory loss, brain fog and forgetfulness. Dr. Michaela McKenzie © Mercury affects all of the following: How Does Mercury Affect the Brain and Spinal Cord? Methyl mercury targets and kills neurons in specific areas of the nervous system: Visual Cortex Cerebellum Dorsal root ganglia Mercury loves Sulfur groups Sulfur groups are found in many areas of the body Mercury vapor crosses the Blood Brain Barrier - it binds to the sulfur groups in Myelin and Unravels the Myelin --- BRAIN FOG The thyroid is full of Sulfur Groupss Demyelination - damage to protective covering (myelin sheath) surrounding nerve fibers in your brain & spinal cord When the myelin sheath is damaged, nerve impulses slow or even stop, causing neurological problems Dr. Michaela McKenzie © Mercury affects the Thyroid Gland What are the Causes of Hashimoto's Thyroiditis? •Environmental Toxins Such as Mercury and Pesticides (Heavy Metal Poisoning!) •Hashimoto’s is leading cause of hypothyroidism and goiter in the United States.atess. •25 percent may develop additional conditions such as Type 1 diabetes, rheumatoid arthritis, pernicious anemia, adrenal insufficiency, lupus, and other autoimmune disorders. Dr. Michaela McKenzie © Several mechanisms have been proposed to explain how mercury kills neurons: • Protein inhibition • Disruption of mitochondria function Porphyrin biosynthesis pathways inhibited by toxic metalssss • Disruption of neurotransmitters • Direct affect on ion exchange in a neuron • Destruction of the structural framework of neurons Dr. Michaela McKenzie © Scientific studies have identified Dental Mercury as a potentially causational or exacerbating factor in the following conditions: Dr. Michaela McKenzie © Highlight On: Mercury Fillings with High Copper • 1975 High levels of copper were added to amalgam fillings • Were touted by the ADA to be “state of the art” because they didn’t release mercury • European studies found high-copper amalgams released 50 times more mercury • 1976 – increase in autoimmune disorders. Specifically onset of ALS or Lou Gehrig’s Disease • 1976 – incidence of Multiple Sclerosis (MS) jumped from 8,800 per year to 123,000 in one year. The year high copper was added to amalgams. History of Hg in Dentistry Dr. Michaela McKenzie © The History of Mercury Amalgam Dental Fillings: In 1819 the English Chemist – Bell, first discovered that he could combine silver and mercury and it would form an amalgamation. In 1826 amalgam was first used in England and France to fill dental cavities. Photo Credit: Randall Mooore; Evidenc e of Harm Barbers became the first dentists in the U.S. – because of their reclining chairs ●In 1833 the Crawcour Brothers came over from France and introduced Mercury Amalgam fillings to the U.S. ●In the 1850's, the American Society of Dental Surgeons banned the use of mercury fillings for its members. ●The pro-mercury faction of dentists founded the American Dental Association (ADA) in 1859. Dr. Michaela McKenzie © History of the Dental Amalgam Controversy 1819 Invention of silver/mercury amalgam by the English chemist, Bell. 1826 First use of dental amalgam in England and France. 1830 Amalgam fillings first used in the U.S. 1840 Organized dentistry American Society of Dental Surgeons formed. Members were required to sign a pledge promising not to use mercury fillings. 1859 American Dental Association was formed. The ADA supported the use of silver amalgam then as the filling material of choice, as it still does today. 1926 The German chemist, Dr. Alfred Stock researched mercury poisoning and identified through his research that silver amalgam fillings in the mouth were a source of mercury vapor. 1957 Dr. Karl 0. Frykholm's studies in Sweden concluded that when saliva covered the amalgam filling, mercury is no longer released. 1976 The Federal Drug Administration pronounced acceptance of amalgam fillings and "grandfathered" their approval under the G.R.A.S. (generally recognized as safe) category, due to its long term usage. 1979 Research began appearing in the literature documenting that mercury vapor was constantly being released from amalgam fillings, especially when the fillings were stimulated by chewing, brushing, or heat exposure. 1984 Human autopsy studies were published which demonstrated that the amount of mercury found in brain and kidney tissue was directly related to the amount of mercury amalgam fillings in the teeth. Significant research at the University of Calgary School of Medicine demonstrated that mercury from dental amalgam fillings could be found in the blood and tissues of pregnant mothers and their babies within a few days. 1990 The first controlled researches on the effects of dental amalgam were published. The research cited significant effects of mercury amalgam on various tissues and organs in experiments with monkeys and sheep. The media became involved when the T.V. show "60 Minutes" aired a segment entitled, "Is There A Poison In Your Mouth?" 1991 Many D.A.M.S. (Dental Amalgam Mercury Syndrome) support groups became more active in consumer awareness of the mercury amalgam issue. The F.D.A. "reviewed" amalgam as a filling material and declared that current evidence was insufficient to condemn amalgam. They did recommend, however, further studies be done. August, 1991 The National Institute of Health Technology Assessment Panel on Dental Materials issued a statement that amalgams are safe. 1992 February: At the annual meeting of the Society of Toxicology, medical scientists presented five studies demonstrating adverse health effects of mercury exposure from amalgam fillings. WHY IS THERE THE NEED FOR MERCURY-FREE & MERCURY-SAFE DENTISTRY? BECAUSE MERCURY is Toxic to HUMANS… ֏֏֏ A 2005 - World Health Organization report warned of mercury: “It may cause harmful effects to the nervous,
