Aluminum is discovered
1827 Aluminum is discovered.
1916 The first evidence of brown mottling of teeth is reported in the United States.
1922 Aluminum production (along with production of toxic by-product sodium fluoride) increases. Aluminum cookware is mass introduced in the US, beginning the gradual accumulation of aluminum in the brains of Americans. Additional aluminum is injected into society in "antacids".
1931 Fluoride in drinking water is found to be the cause of brown teeth - now known as dental fluorosis.
1938 German chemist Schrader discovers Sarin, 10 times more lethal than Tabun, which is compounded various compounds including Sodium Fluoride, which is later dumped into planetary water supplies to placate the population.
1940 Soviet concentration camps maintained by fluoride administration to inmates to decrease resistance to authority and induce physical deteriorization.
1942 Germany becomes worlds largest producer of aluminum (and Sodium Fluoride)
1943 Researchers from the US Public Health Service examine the health of residents of Bartlett, Texas to see if the 8ppm fluoride in the drinking water was affecting their health. It was checked again in 1953. They find that the death rate in Bartlett was three times higher than a neighboring town which contained 0.4 ppm fluoride.
1943 The Journal of the American Medical Association on September 18, 1943, states, "fluorides are general protoplasmic poisons, changing the permeability of the cell membrane by inhibiting certain enzymes. The exact mechanism of such actions are obscure. The sources of fluorine intoxication are drinking water containing 1ppm or more of fluorine, fluorine compounds used as insecticidal sprays for fruits and vegatables (cryolite and barium fluoro- silicate) and the mining and conversion of phosphate rock to superphosphate, which is used as a fertilizer. That process alone releases approximately 25,000 tons of pure fluorine into the atmosphere annually. Other sources of fluorine intoxication is from the fluorides used in the smelting of many metals, such as steel and aluminum, and in the production of glass, enamel and brick."
1944 Oscar Ewing is put on the payroll of the Aluminum Company of America (ALCOA), as an attorney, at an annual salary of $750,000. Within a few months, Ewing was made Federal Security Administrator, with the announcement that he was taking a big cut in salary. The US Public Health Service, then a division of the FSA, comes under the command of Ewing, and he begins to vigorously promote fluoridation nationwide. Ref: May 25-27 Hearings before the Committee on Interstate and Foreign Commerce. A by-product of aluminum manufacture is toxic sodium fluoride. Ewings public relations strategist for the fluoride campaign was the nephew of Sigmund Freud, Edward L. Bernays. Bernays conducts a public relations campaign to promote fluorine ingestion by applying Freudian theory to induce public acceptance. It was one of Bernays most successful campaigns.
1944 The Journal of the American Dental Association on October 1, 1944 warned that "We do know that the use of drinking water containing as little as 1.2 to 3.0 ppm of fluorine will cause such developmental disturbances in bones as osteoporosis, and we cannot run the risk of producing such systemic disturbances in applying what at present is a doubtful procedure intended to prevent development of dental disfigurement in children. In the light of our present knowledge or lack of knowledge of the chemistry of the subject, the potentialities for harm far outweigh those for good."
1948 Study done in England where bone defects in three groups of school boys were studied. Two groups were from districts where the water supply was practically free of fluorine. The third group was from the town of Launton, where the natural water supply contains 1ppm of fluorine (the same as the level deemed "safe" by the U.S. Public Health Service). X-ray examination revealed that 20 percent of the first two groups had mild non-specific spinal irregularities. In the third group, the one consuming 1ppm fluoride in their water, 64% were found to have spinal defects, and lesions were more severe.
1949 Autopsies of soldiers killed in Korea reveal 80% had advanced heart disease.
1951 The U.S. Public Health Service, with the cooperation of the American Dental Association, holds a meeting of state dental directors at which the methods for promotion of fluoridation were outlined. Thus the USPHS formed an alliance with medical trade unions and industry to promote the addition of toxic fluorides to the public water supplies. A concentration of 1.2 ppm was suggested, and state dental directors were instructed to lie to the public about the toxic effects of sodium fluoride, deliberately misinform the public by relating the presence of "high-fluoride areas" to "less cancer and less polio" - an entire public relations campaign meant to convince the public to allow themselves to be medicated - just like the inmates in Soviet and German prisons and camps. Their technique was not to refute the thing but to show that the opposite was true, even if the opposite was not true.
1952 The American Dental Association publishes an issue of its Journal instructing its dentists not to discuss their personal opinions about fluoride.
1952 From 1952 to 1956, the cities on the "fluoridation list" began to fluoridate their water supplies. As the process of water fluoridation continued, the cancer death rate of the fluoridated cities began to far exceed the rate of the unfluoridated cities.
1952 US Representative Dr.A.L.Miller, Chairman of the Special Committee on Chemicals and Foods, stated, "I sometimes wonder if ALCOA Aluminum and its subsidiaries might not have a deep interest in getting rid of sodium fluoride, a toxic waste product of the aluminum industry. In this connection it is interesting to note that the person in charge of the public heath, Oscar Ewing, is also an attorney for ALCOA."
1952 82nd Congress, 2nd Session, Hearings of the Select Committee to Investigate Use of Chemicals in Food and Cosmetics. Dr. Miller "The US Dental Assn made some examination and recommended to the farmers that fluorine not be added to the water of pregnant sows because it did something to the pigs that were unborn" Dr. Porterfield "There is more money available for matters that have economic value than there is for health."
1954 A study is published which links fluorides and the development of cancer in animals. Ref: A Taylor, "Sodium Fluoride in the Drinking Water of Mice", Dental Digest, Vol 60, pp170-172.
1954 C.E.Perkins, I.G.Farben chemist, admits fluoride is to reduce resistance in people to authority.
1956 March 1956 issue of the Journal of the American Dental Association, H.C. Hodge remarks, "skeletal deposition of fluoride is a continuing process in which a considerable portion of the ingested fluoride, perhaps 25 to 50%, is deposited in the skeleton."
1957 In a 1957 AMA report it was stated " It is too early to know what the effects of artificial fluoridation will be. What is reported as a reduction in dental decay may in fact be a delay in recognition of decay, and reasons given for believing that artificially fluoridated water will have the same effects as water with natural fluoride are not valid."
1957 Records for New Britain, Connecticut (where the use of industrial fluorides had been in use for 6 years) showed that some of the children's teeth had been damaged beyond repair where the water is fluoridated, even when the percentage of industrial fluorine is kept at or below 1 ppm, mottling is produced in 10-15% of the children examined. Mottled teeth are teeth showing symptoms of fluorosis, and the enamel of mottled teeth is brittle and subject to mechanical injury which is difficult or impossible to repair.
1958 Dr. A. Aslander in Stockholm in 1958 (Tooth Formation in the Light of Plant Nutrition) that indicates that food supplementation with bone meal has a most profound decay protective effect in children.
1958 In October 1958, Dr. J.F. Montague, a medical doctor, published material reflecting his growing concern over fluoridation in the Journal of the International College of Surgeons connecting the presence of fluorine in the human body to cancer. Also in 1958, an interesting piece of work was done by Dr. James Kerwin, a dentist, in which it was shown that the simultaneous presence of fluorine and strontium 90 in the human body may result in a greater accumulation of both substances in which compounds like strontium fluoride are formed. Because of the low solubility of these substances, the body has a very hard time getting rid of them. His report was published in Dental Digest in February 1958.
1959 In the report of the proceedings of the 3rd Medical-Dental Conference on the Evaluation of Fluoridation, held on March 7, 1959 in New York City, the committee concluded that "It is apparent that the practice of fluoridation is not the simple, trustworthy procedure that the promoting authorities have given the profession and the public to believe. Added to the lack of control of fluorides at the consumers tap are these major uncertainties: the gross variation in individual water consumption, the varied intake of fluorides in food and the fluoride intake from atmospheric and occupational exposure. These unpredictable issues make meaningless any talk about "controlled individual fluorine intake." Most, if not all of this research has been buried by the authorities, who maintain glibly that "fluoride compounds are safe in the water supply".
1959 Fluorides were used as an enzyme inhibitor in a study by J.D. Ebert that was published in 1959 on the metabolic pathways by which organs in an embryo are formed. In low concentrations, he found that sodium fluoride blocked almost completely the regions destined to form muscle, primarily affecting the heart muscle. In higher concentrations, it caused the entire embryo to disintegrate in a clear-cut pattern, starting with the heart-forming region.
1959 As early as 1959, the knowledge existed that the presence of fluoride in human bodies hastens the absorption of radioactive substances present in the environment. In a report to the Atomic Energy Commission's Division of Biology and Medicine entitled "The Metabolism of Alkaline Earth Metals by Bone" by F.W. Lengemann, professor of chemistry at the University of Tennessee on March 23, 1959, it was scientifically shown that the presence of fluorine and other environmental substances such as lead and cyanide in the human body increased the ratio of strontium 90 to calcium in bone.
1959 In 1959, the Ontario Minister of Health, Dr. Dymond, announced that no further fluoridation would be permitted there, because "no one knows for sure what the effect is to persons given fluoride throughout a lifetime."
1959 In research conducted on the incidence of Mongolism in cities in Wisconsin, Illinois and the Dakotas published in 1959 in the official publication of the French Academy of Medicine, it was found that as the percentage of fluorides in the water rose, there was a parallel rise in the incidence of Mongoloid births the age of the mothers giving birth to Mongoloid babies also declined with rising fluoride levels. It is interesting that. in the first three years of fluoridation, New Britain, Connecticut experienced a 150% rise in still births.
1960 In 1960, the American Dental Association issued a pamphlet for public consumption called Fluoridation Facts: Answers to Criticisms of Fluoridation. In defense of the use of toxic fluoride compounds in public water supplies (which is a grievous crime against humanity, since it means mandated involuntary public medication), they used the logic that "people have been known to live to a ripe old age" i n areas where the water supply is fluoridated. Unfortunately, they neglected to mention that the addition of fluoride to the water supply correlated directly with the number of still births, mongoloid children, brittle teeth and enlarged dental root structures, adverse spinal conditions, osteomalacia (softening of the bones) and osteoporosis (abnormally porous and spaced structure inside bone) in the medicated population as opposed to control populations that were unmedicated.
1960 A study is done in Japan that involved examination of fluoride deposition in the fetuses of dogs. It was found that the quantity of deposited fluorine was especially large in bones, largest in the cranial bone as well as the lower leg bone. The quantity of fluorine deposition was parallel with the progression of the calcification. They also proved that the deposit of fluorine on teeth and bones starts through the placenta as early as the embryo period, and then takes place through the mothers milk through the infancy period, and through food, as well as directly through the inside of the oral cavity. As fluorine is a known active enzyme poison, it is known to affect cell division (mitotic) in the fetus, resulting in anatomical anomalies (teratism).
1961 In Great Britain, Dr. R.A.Holman of the Royal Institute of Pathology discussed fluoride poisoning in an article in the April 15, 1961 issue of the British Medical Journal. He noted that the long-term effects of sodium fluoride ingestion needed much more investigation, and continued, "Fluoride is a well-known inhibitor of several enzyme systems, and can form spectroscopically recognizable compounds with the enzyme catalase, resulting in its inhibition. Catalase poisoning has been linked with the development of viruses and the causation of a number of diseases, including cancer. Many observers have suggested that the agents (fluorides and other toxic environmental substances) which decrease the catalase the cells may predispose those cells to tumor formation. Voisin has said, "the method most likely to solve the problem of cancer is to ask why the cancer cell is lacking in catalase and try to prevent its impoverishment from taking place.
1963 American Academy of Sciences study shows low fluoride levels increase tumors.
1963 A study is published which links fluorides and development of cancer in animals. Ref: Irwin Herskowitz and Isabel Norton "Increased Incidence of Melanotic Tumors...Following Treatment with Sodium Fluoride", Genetics, Vol 48, pp307-310.
1969 A Congressional study reveals that 37 of 49 top officials of the FDA who left the agency moved into high positions within pharmaceutical companies they had regulated.
1971 Germany bans water fluoridation.
1972 Sweden bans water fluoridation.
1973 Netherlands bans water fluoridation.
1974 The Safe Water Drinking Act is passed. Environmental Protection Agency (EPA) sets maximum contamination levels (MCL) for various water pollutants, including sodium fluoride. The EPA sets the fluoride contaimination level at an unbelievable 1.4 ppm for "warmer climates" and up to 2.4 ppm for "colder climates". Furthermore, the American Dental Association begins pressuring the EPA to raise the MCL for fluoride in public water to 8 ppm, when it is fully known that systemic damage occurs below 1 pmm. The former US Surgeon General C. Everett Koop is among those who join the drive to increase the MCL for fluoride, even doing television ads proclaiming that fluoridation was "absolutely safe". Shown slides of severe fluorosis damage to a childs teeth at 4ppm, ADA spokesperson Lisa Watson maintains that it does "not involve health effects but is only a cosmetic problem". The National Drinking Water Advisory Council refuses to recommend raising the fluoride MCL, and came close to recommending its lowering, but the EPA farmed out research work to ICAIR Life Systems, which issues a fraudulent report (confirmed by ICAIR employee Dr. John Beaver) that is woven into the US EPA report on fluoride, resulting in the EPA recommendation of MCL for sodium fluoride in public water to be 4 ppm.
1975 A General Accounting Office (GAO) study of the FDA reveals that 150 FDA officials owned stock in the companies they were supposed to regulate.
1975 Dr. John Yiamouyiannis publishes a preliminary survey which shows that people in fluoridated areas have a higher cancer death rate than those in non-fluoridated areas. The National Cancer Institute attempts to refute the studies. Later in 1975, Yiamouyiannis joins with Dr. Dean Burk, chief chemist of the National Cancer Institute (1939-1974) in performing other studies which are then included in the Congressional Record by Congressman Delaney, who was the original author of the Delaney Amendment, which prohibited the addition of cancer-causing substances to food used for human consumption. Both reports confirmed the existence of a link between fluoridation and cancer. (Note: Obviously Dr. Burk felt free to agree with scientific truth only after his tenure at NCI ended, since his job depended on towing the party line).
1976 Dr. D.W.Allman and co-workers from Indiana University School of Medicine feed animals 1part-per-million (ppm) fluoride and notice the urinary levels and tissue levels of a substance called cyclic AMP (adenosine monophosphate) increased by more than 100%. They also found that in the presence of aluminum in a concentration as small as 20 parts per billion, fluoride is able to cause an even larger increase in cyclic AMP levels. Cyclic AMP inhibits the migration rate of white blood cells, as well as the ability of the white blood cell to destroy pathogenic organisms. Ref: Journal of Dental Research, Vol 55, Sup B, p523, 1976, "Effect of Inorganic Fluoride Salts on Urine and Tissue Cyclic AMP Concentration in Vivo". (Note: It is no small accident that toothpaste tubes containing fluoride are often made of aluminum, nor is it an accident that aluminum cookware and fluoride use were injected into the population virtually simultaneously.)
1977 The Congressional Subcommitee on Intergovernmental Relations convenes two (2) full Congressional Hearings on the subject of fluorides. During the hearing, it was proven that (1) The "scientific efforts" of those promoting fluoridation were fraudulent, and (2) That other existing studies proved beyond a doubt that approximately 10,000 excess cancer deaths per year could be attributed to fluoridation in the United States.
1978 Consumer Reports publishes a two part article in July and August 1978 which includes the claim "the simple truth is that there is no 'scientific controversy' over the safety of fluoridation." Later in 1990, the Technical Director for Consumer Reports disputes the claim, saying "the proponents of fluoridation insist that there are no grounds for controversy at all, and with that I totally disagree. The point is that this is a legitimate scientific controversy." The technical director in 1990 is Dr.Edward Groth III.
1978 The German magazine Stern reports on the Turkish village of Kizilcaoern, where the drinking water contains 5ppm fluorides. All of the children have brown teeth. Women produce dead babies after only four months of pregnancy. All the inhabitants suffer from tremendous premature aging. The same fluoride-related brittle-bone disorders have been observed among people drinking water with as little as 0.7 ppm fluoride.
1978 A court case was won in Pennsylvania that proved fluoridation was harmful and resulted in a ban. It received great publicity, much to the concern of the American Dental Association and the industry. (See 1979)
1979 The January 20th edition of the New York Times carried a story in which a child was killed because of a lethal dose of fluoride at a city dental clinic. The parents were awarded $750,000.
1979 On November 11th, up to 50ppm fluoride was dumped into the Annapolis Maryland water supply, resulting in the poisoning of 50,000 people. Many died of heart failure during the week following the spill.
1981 Drs. Susheela and Sharma and co-workers from the India Institute of Medical Sciences find that fluoride exposure disrupts the synthesis of collagen in the body and leads to the breakdown of collagen in bone, tendon, muscle, skin cartilage,lung, kidney and trachea. It appears that fluoride disruption of collagen synthesis in cells responsible for laying down collagen leads these cells to try and compensate for their inability to put out intact collagen by producing larger quantities of imperfect collagen and/or non-collagenous protein. Ref: "Fluoride poisoning and the Effects of Collagen Biosynthesis of Osseous and Non-osseous Tissue", Toxicological European Research, Vol 3, No.2, pp99-104, 1981.
1981 Dr.John Emsley and co-workers at King's College in London find that fluoride reacts strongly with the bonds which maintain the normal shapes of proteins in the body. The work is subsequently confirmed by Dr. Steven Edwards and co-workers from the University of California in San Diego, and by Drs. Froede and Wilson from the University of Colorado at Boulder. By distorting the configuration of the body's own protein, the immune system attacks its own protein , resulting in an autoimmune or allergic response. Fluroides contribute to the development of an Acquired Immune Deficiency Syndrome, which is covered up by the media and medical community, which maintains a public focus on a viral cause for the problem, promoting the harmless HIV virus as the "cause" for "AIDS", covering up the pharmo-chemical sensitization of the population which has complex legal ramifications.
1981 Dr.Robert Clark from the Boston University Medical Center shows that fluorides (as in fluoridated water supplies, toothpaste,etc) stimulate granule formation and oxygen consumption in white blood cells when they were not challenged with a foreign agent, but inhibited these processes when the white blood cell needed them to fight off foreign agents. Ref: "Neutrophil Iodination Reaction Induced by Fluoride: Implications for Degranulation and Metabolic Activation" Blood, Vol 57, pp913-921, 1981.
1982 Peter Wilkinson at the University of Glascow testifies before the Scottish High Court in Edinburgh in a legal case entitled "Inhibition of the Immune System with Low levels of Fluoride" which revealed that fluoride decreases the migration rate of human white blood cells. At a concentration of .2ppm (which is .8ppm below the "approved" level of 1 ppm), relative white cell migration rate is reduced 8%. A concentration of 1ppm would produce a physiological decline of around 10%. Fluoride added to water supplies, tooth paste, school dental washes, supplement pills and dentists visits are increased and promoted, contributing to a further co-factor in the decline of the immune capability of the population.
1982 In
Science magazine, Vol 217 p26-32, Dr. Dennis Leverett of the University of Rochester states, "if there are increasing concentrations of fluoride in the food chain, particularly food for infants, then we should expect fluorosis to be increasing in the population as well. The widespread use of fluorides might have created a situation in which we are approaching a critical mass of fluoride in the environment. There needs to extensive research done." Later in 1983 he would contradict himself at the University of Michigan symposium.
1983 U.S. Environmental Protection Agency deputy assistant administrator Rebecca Hammer points out that fluoride-polluting industries can get paid for using public drinking waters as a sewer for their toxic waste products when she says "this agency regards the use of fluosilic acid as a source of fluorides for water fluoridation an ideal environmental solution to a long standing problem of contamination of the water and air from fertilizer manufacturing."
1983 A symposium takes place at the University of Michigan after years of planning between the US Dept of Health and Human Services, the USPHS Michigan state health plans, the Kellogg Foundation, and Medical Products Labs to "discuss the status of organized opposition to fluoridation, to analyze probable motives influencing the anti-fluoride movement, to develop political and legal strategies for the defense and promotion of fluoridation, and to access the need for a national fluoridation strategy." Dr. Dennis Leverett of the University of Rochester reported that his commitee felt that fluoridation was a "political issue and not a scientific situation". See 1982,1988.
1983 Dr.John R. Farley and co-workers from Loma Linda University show that treatment of bone cells with less than 1ppm fluoride increases collagen formation by 50 percent (unstable collagen. See 1981 Susheela). Ref: "Fluoride Directly Stimulates Proliferation and Alkaline Phosphatase Activity of Bone Forming Cells", Science, Volume 222, pp330-332, 1983.
1984 The 1984 issue of Clinical Toxicology of Commercial Products indicates that 1/10
oz of fluoride in the human body is lethal for a 100 pound adult human. Fluoride toothpaste contains up to 1mg/gram of fluoride. A whole tube contains about 199 mg of fluoride - enough to kill a 25-pound child. Toothbrushing causes ingestion of 0.25 mg/day.
1984 Researchers in Japan were achieving some degree of understanding about fluorides consumption and human cancer. Dr. Takeki Tsutsui of the Nippon Dental College showed in 1984 that "fluoride caused not only genetic damage but was also capable of transforming normal human cells into cancer cells." In Dr.Tsutsui's study, the level of fluoride used was the same level that the United States National Cancer Institute suggested should be used in a study to determine whether fluoridation of public water supplies causes cancer. The level of fluoride deemed "safe" by the United States in 1 ppm. The researchers in Japan found that cells treated with fluoride produced cancer.
1985 Dental hygenists, psychiatrists, public relations experts, education specialists and psychologists (no scientists) form "The American Oral Health Institute" and release a book "Abuse of the Scientific Literature in an Antifluoridation Pamphlet", in which they attack scientific data relative to fluoride and those who oppose its use in the public water supply. An examination of the book, ironically, revealed "abuse of scientific literature" on the part of the authors, who demonstrated their lack of scientific expertise and themselves were guilty of deception and misrepresentation of scientific fact.
1986 The Rocky Mountain Poison Control Center reports 87 cases of fluoride poisoning . Two cases involved fluoride treatment by a dentist. One 13 month old child died. Twenty five suffered gastrointestinal symptoms. Sodium fluoride is the most frequent single cause of acute poisoning in children.
1988 Dr.Joel Boriskin, chairman of the ADA national fluoridation advisory committee, in an address before the Calgary Health Department, claims that "1500 mg of fluoride per day is prescribed to older people that have progressive hearing loss". (Note: 1500 mg/day is a lethal dose).
1988 Researchers at the Argonne National Laboratory discover that fluoride promotes and enhances the carcinogenicity of other cancer-causing chemicals in the food and environment. Interestingly, this work confirmed studies sponsored by the United States National Cancer Institute conducted back in 1963 by Herskowitz and Norton at Saint Louis University. More than 30 years ago, these scientists showed that low levels of fluoride increased the incidence of melanotic tumors in living organisms from 12 to 100% - often these tumors were induced by fluoride over a period of days. These studies were further amplified by work done by the Taylor's at the University of Texas which found that 1 ppm fluoride in drinking water increased tumor growth rate in mice by 25%.
1989 On March 30, 1989, the California Department of Health Services reported that Niagara brand bottled water was found to contain 450ppm fluoride. The state health director, Kenneth Kizer, warned residents that consumption could be fatal.
1989 In 1989 Dr.Yiamouyiannis used the Freedom of Information Act to obtain carcinogenicity studies conducted by Proctor and Gamble (one of the makers of fluoridated toothpaste) that were submitted to (and covered up by) the United States Public Health Service. These studies showed dose dependent cell abnormalities caused by fluoride. These results were reported in the February 22, 1990 issue of the Medical Tribune. Additional studies by Proctor and Gamble scientists confirmed the link between oral precancerous growth and fluoride, as well as an increase in osteomas (bone tumors) and osteosarcomas (bone cancer). In fact, the National Cancer Institute found in 1991 that the incidence of bone cancer was 50% higher in men ages 0-19 years of age exposed to fluoridated water compared to those who were not.
1989 On February 23, 1989, Battelle released the results of its study of fluorides on mice. A most curious result of the study, from the USPHS point of view, was that fluoride induced the occurrence of an extremely rare form of liver cancer, called hepatocholangio carcinoma, in fluoride-treated male and female mice. Two months later in April of 1989, Battelle released the results of its study of fluorides and rats. The study showed a dose-dependent relationship between the incidence of oral cancerous tumors and fluorides. It is interesting to note that mice and rats yielded different The results with fluoride - different types of cancer. As a response to the Battelle study, the National Cancer Institute from examined the incidence of oral cancer in fluoridated and non-fluoridated countries over the period from 1973 to 1987. The National Cancer Institute study found that as exposure to fluoridation increases, so does the incidence of oral cancer; sometimes as much as a 50% increase in oral cancer rates occur in fluoridated areas - this translates to 8,000 new cases of oral and pharyngeal cancer per year, needless pain and suffering and a financial windfall to the medical and pharmaceutical factions that concern themselves with treatment.
1990 The National Toxicology Program issues a Press Release with data confirming findings of a link between fluoride and osteosarcomas as well as higher rates of oral cancer in rats. (January 1990)
1990 A study by Dr.John Yiamouyiannis on 39,000 school children contradicts any alleged benefits from the use of sodium fluorides.
1990 Dr. John Colquhoun in New Zealand is forced into early requirement in New Zealand after he conducts a study on 60,000 school children and finds no difference in tooth decay between fluoridated and unfluoridated areas. He additionally finds that a substantial number of children in fluoridated areas suffered from dental fluorosis. He makes the study public.
