OBJECTIVES: This study has three aims: 1) to determine the trends and prevalence of dental fluorosis and caries among persons aged 6-19; 2) to examine the association between dental fluorosis and caries among persons of the same age group; and 3) to investigate the influence of dental fluorosis and caries on oral health-related quality of life (OHRQoL) among people aged 16-49 in the United States. METHODS: The data from the National Health and Nutrition Examination Survey (NHANES) 1999-2004 and 2011-2012 were analyzed. For aims 1) and 2), individuals aged 6-19 years, who completed the home interview and oral health examination were included (n=9,493, n=2,411, respectively). For aim 3, the data from NHANES 2003-2004 were analyzed including only people aged 16-49, who completed the home interview and both conditions examination (n=3,035). The reason behind age restriction is that people aged 16-49 were targeted to answer OHRQoL questions. Dental fluorosis was measured by Deans Index (6-categories ...
Dental Fluorosis is also called as mottling of tooth enamel. This is a condition which generally happens at a stage when the tooth starts to develop and is seen among the younger generations. The primary cause of this condition is over exposure to fluoride. In case you happen to see tiny spots or streaks on the enamel of your teeth you need not fear as this is considered as the mildest form of the condition. However you need to worry and seek dentist appointment if you notice tooth discoloration and brown marks on your teeth.. Details about the causes of Fluorosis. To understand why fluorosis occurs we need to know that our tooth is made out of hydroxyapatite and carbonated hydroxyapatite. When the usage of fluoride increases the composition of Fluor apatite also increases which leads to the marks and spots on teeth.. Risks involved in Dental Fluorosis. The most important concern of patients suffering from Dental Fluorosis is the cosmetic changes that happen in their teeth. The change is more ...
There are no studies of oral health and esophageal cancer in Africa, or of this areas endemic dental fluorosis, an irreversible enamel hypo-mineralization due to early-life excessive fluoride. During 2014-18, we conducted a case-control study of squamous cell esophageal cancer in Eldoret, western Kenya. Odds ratios (AORs (95% confidence intervals)) were adjusted for design factors, tobacco, alcohol, ethnicity, education, oral hygiene and missing/decayed teeth. Esophageal cancer cases (N=430) had poorer oral health and hygiene than controls (N=440). Compared to no dental fluorosis, moderate/severe fluorosis, which affected 44% of cases, had a crude OR of 20.8 (11.6, 37.4) and on full adjustment was associated with 9.4-fold (4.6, 19.1) increased risk, whilst mild fluorosis (43% of cases) had an AOR of 2.3 (1.3, 4.0). The prevalence of oral leukoplakia and tooth loss/decay increased with fluorosis severity, and increased cancer risks associated with moderate/severe fluorosis were particularly ...
Using these eight standards, we assessed the publications that we had located. With publications that met those criteria, we recorded the information from them on a data extraction sheet. Differences among studies, such as which index of dental fluorosis was used, population selection criteria, and retrospective information, were also assessed.. RESULTS. The literature search yielded 24 papers. Of those 24, 14 of them met our inclusion criteria. We divided those 14 papers into three groups. The first group dealt with studies conducted in naturally fluoridated areas where water fluoride was above optimal (those studies will be shown in Table 1). The second group (which will be shown in Table 2) included studies conducted in areas where water had negligible, unknown, or optimal amounts of fluoride and fluoridated salt was used. The third group (which will be shown in Table 3) dealt with studies where the altitude of residence was reported to be related to a higher prevalence of dental fluorosis, ...
The prevalence of dental fluorosis appears to be on the increase. Although in its mild form the condition is not considered to be of cosmetic significance, the more severe forms can cause great psychological distress to the affected individual. This article discusses the prevalence and mechanisms of dental fluorosis, and the aesthetic management of severe fluorosis in the young patient.. ...
John Spottiswode reminds the panel that the World Health Organization advises communities considering fluoridation that they should first check to see what the communitys current exposure to fluoride is from other sources. While promoters often cite the WHOs support for this practice they never acknowledge this important caveat. With so many children now impacted with dental fluorosis such an omission is utterly irresponsible. Children could either have their urine tested for fluoride or examined for the signs of dental fluorosis. The early promoters of fluoridation believed that at optimal levels of fluoride (1 ppm) approximately 10% of children would develop dental fluorosis in its mildest form. Running this logic backwards: if one found that over 10% of children had dental fluorosis in a community (before fluoridation) then we can assume that they are getting the optimal fluoride exposure and they dont need any more. Today over 10% of children living in communities with fluoride levels ...
Common causes of fluorosis include inhalation of fluoride dusts/fumes by workers in industry, consumption of fluoride from drinking water (levels of fluoride in excess of levels that are considered safe[4]), and consumption of fluoride from drinking tea,[5] particularly brick tea. Skeletal fluorosis can be caused by cryolite (Na3AlF6, sodium hexafluoroaluminate), and the disease was first recognized among workers processing cryolite.[6]. In India, most in Nalgonda (Telangana), the most common cause of fluorosis is fluoride-laden drinking water which is sourced as groundwater from deep-bore wells. Over half of groundwater sources in India have fluoride above recommended levels.[7]. Fluorosis can also occur as a result of volcanic activity.[8] The 1783 eruption of the Laki volcano in Iceland is estimated to have killed about 22% of the Icelandic population, and 60% of livestock, as a result of fluorosis and sulfur dioxide gases.[9] The 1693 eruption of Hekla also led to fatalities of livestock ...
Chronic fluoride over-exposure during pre-eruptive enamel development can cause dental fluorosis. Severe dental fluorosis is characterized by porous, soft enamel that is vulnerable to erosion and decay. The prevalence of dental fluorosis among the population in the USA, India and China is increasing. Other than avoiding excessive intake, treatments to prevent dental fluorosis remain unknown. We previously reported that high-dose fluoride induces endoplasmic reticulum (ER) stress and oxidative stress in ameloblasts. Cell stress induces gene repression, mitochondrial damage and apoptosis. An aromatic fatty acid, 4-phenylbutyrate (4PBA) is a chemical chaperone that interacts with misfolded proteins to prevent ER stress. We hypothesized that 4PBA ameliorates fluoride-induced ER stress in ameloblasts. To determine whether 4PBA protects ameloblasts from fluoride toxicity, we analyzed gene expression of Tgf-β1, Bcl2/Bax ratio and cytochrome-c release in vitro. In vivo, we measured fluorosis levels, enamel
Last May I raised the possibility that the much touted relationship of small IQ declines for children living in areas with naturally high fluoride in drinking water could be associated with severe dental fluorosis and not a chemical neurotoxicant (see Confirmation blindness on the fluoride-IQ issue). In November I repeated this argument because the recently published work by Choi…

A new study finds cognitive function defects, like IQ, in children are not significantly related to fluoride in drinking water. But they are associated with medium and severe dental fluorosis. This interests me for two reasons: The report is by Choi and Grandjean who had also authored the 2012 meta-review often used by anti-fluoride activists to claim that…
The details of bibliography - Occurrence of dental fluorosis in Australian Aboriginal children resident in Carnarvon, Western Australia
Fluoridation IS possibly the greatest fraud perpetrated on the largest number of people ever. The compounds used to fluoridate water supplies are NOT natural products: they are highly toxic waste products of industry that are expensive to dispose of in any other way than through public water supplies. These fluoride compounds are contributing to millions of children being chronically fluoride poisoned: the visible evidence of this is the high percentage of children [and now adults] with dental fluorosis [mottled teeth]. Dental fluorosis is universally acknowledged as being an indication that the person has been chronically fluoride poisoned during the developmental stage of their teeth. Fluoride toothpaste is also adding to the heavy burden of fluoride that people are now subjected to. There are even children/people in non-fluoridated areas who have developed dental fluorosis.. Fluoride is known to inhibit thyroid function: correct thyroid function is imperative to good health. In earlier days, ...
Objective. The purpose of this study was to evaluate caries and dental fluorosis among Mexican preschoolers and school-aged children in a non-endemic zone for fluorosis and to measure its biological indicators. Methods. DMFT, DMFS, dmft, dmfs, and CDI indexes were applied. Fluoride urinary excretion and fluoride concentrations in home water, table salt, bottled water, bottled drinks, and toothpaste were determined. Results. Schoolchildren presented fluorosis (CDI = 0.96) and dental caries (DMFT = 2.64 and DMFS = 3.97). Preschoolers presented dmft = 4.85 and dmfs = 8.80. DMFT and DMFS were lower in children with mild to moderate dental fluorosis (DF). Variable fluoride concentrations were found in the analyzed products (home water = 0.18-0.44 ppm F, table salt = 0-485 ppm F, bottled water = 0.18-0.47 ppm F, juices = 0.08-1.42 ppm F, nectars = 0.07-1.30 ppm F, bottled drinks = 0.10-1.70 ppm F, toothpaste = 0-2,053 ppm F). Mean daily fluoride excretion was 422 ± 176 µg/24 h for schoolchildren and 367 ±
A key concern of those attending the hearing was the overexposure of their populations to fluoride. In Ireland there is an epidemic of dental fluorosis in children as confirmed by the North South Survey of Childrens Oral Health in Ireland 2002, two of whose authors were present at the hearing. This survey revealed a seven-fold increase in dental fluorosis in Irish 15-year-olds from 1984 to 2002. Dental fluorosis, which manifests as mottling or pitting of tooth enamel, is a sign of bodily overload of fluoride.. The committee was also alerted to the fundamental contradictions between the advice from another EU scientific committee, monitoring the safety of cosmetics including toothpaste, and the European Food Safety Authority (EFSA). While fluoride toothpastes must carry labels warning children under six-years not to swallow it as it contains sodium monofluorophosphate, EFSA recently approved the same substance as a permitted food supplement under the Food Supplements Directive. This was cited as ...
Fluorosis as an adverse effect of fluoridation is commoner in water fluoridation than fluoride toothpaste. In measuring fluorosis in Mexican children, Molina-Frechero et al. (2015) evaluated 239 students. Mean age was 11 ± 0.82 and 51% were male. More than half of the population had a type of fluorosis. 29.3% had very mild fluorosis, 20.9% had mild fluorosis, 6.7% had moderate fluorosis while 2.1% had severe type of fluorosis. The mean fluorosis score was 0.887 ± 0.956. The study concluded that the association between frequent brushing using toothpaste high in fluoride concentration and lack of parental supervision during toothbrushing may be a contributing factor to the severity of fluorosis. However, one limitation of the study is that the data used to determine frequency of brushing, type of toothpaste and supervision during study was obtained from a questionnaire filled by the parent. The data collected is prone to self-report bias. Additionally, the study was conducted for a small ...
INTRODUCTION. The effectiveness of fluoridated dentifrices for dental caries reduction is well established in the literature. It is known that the main cariostatic effect of fluoride (F) occurs by its topical action, reducing demineralization and enhancing remineralization of the enamel18.. Recent investigations have confirmed the safety of F in relation to human health, when used as recommended for caries control23. However, it is known that the earliest clinical sign of chronic excessive ingestion of F by young children is dental fluorosis, the prevalence of which has been increasing in the last half of the twentieth century6. The critical period of exposure for all permanent teeth is between 11 months and 7 years of age10. Excessive F intake by persons older than 7 years will not cause dental fluorosis. Some studies have shown the importance of knowing the amount of F present in foods ingested by children because dental fluorosis is a systemic effect caused by excessive F ingestion. It is ...
The situation in certain parts of Andhra such as Nalgonda is very grim. When Daver first recorded cases of skeletal fluorosis from this region in 1945 AD and by Siddique in 1955 AD, there were no children with deformed limbs. These cases with deformed limbs were recorded in 1970s. Rural nutrition in the past few decades has gotten worse in many parts of state and in other parts of the country. National institute of nutrition conducted surveys of status of rural nutrition in 715 villages of seven states in 2002 and 2003. Eighty villages in AP were studied and AP has the distinction of having highest incidence of dental fluorosis among seven states. The results of nutrition study are contained in National nutrition monitoring bureau reports 21 and 22, which reveal the appalling state of nutrition of rural population in the country. Sixty percent of the children below 6 years of age are malnourished and a third of them suffer from severe under weight problem. Only a third of the children studied ...
So youve looked at the research and then disregard it all saying its a wash/tie. Then the argument you present is that other countries water is not as clean as the USAs, therefor fluoride is good? Other countries having polluted water is a cause for their dental problems. Americans have less dental problems because we have cleaner water. Fluoride causes dental fluorosis which is a dental problem. Americans would have less dental fluorosis if we didnt have fluoride in our water, other countries would have more dental fluorosis if it was added to their water. Your argument doesnt make any sense ...

An entire generation of a village in North Gujarat is suffering from fluorosis caused by fluoride pollution in the water sources. Inspite of it being a common and widespread disease with hundreds of people suffering its debilitating effects, the patients receive no care at the village health centers. The health workers shirk duties and the centers, shamefully, do not even have the equipment and resources to deal with this common ailment. People continue to suffer.. I am resident of North Gujarat and a Video Volunteers correspondent. Watch my video which shows the crippling effects of fluorosis in the village of Kashipura.. Fluorosis is a painful and scarring disease. Your teeth turn brown, brittle and fall out. If it not treated on time, the pain in your bones turns chronic. Your joints dont stop hurting. You can barely move. Bones become prone to fractures. Crippling deformities develop over time and even nerves running down your spine can be affected. The afflicted are unable to do even daily ...

In general, safety concerns about dental fluoride and fluoridation relate to a number of factors, including toxicity of fluoride, total fluoride intake, fluoride absorption, the impact on human health, the effect on the environment, water quality, and the engineering aspects.. Anti-fluoridation groups frequently and inappropriately exhibit photographs of children and/or adults having severe fluorosis in which pitting or mottling of the enamel and brown stains are evident and put the blame on water fluoridation, often describing dental fluorosis as a major risk factor for people of all ages. In making dental-health decisions, the risk of developing very mild fluorosis versus the benefit of decreased tooth cavities and dental treatment costs should be considered. Continue reading →. ...
Babies fed infant formula mixed with New Yorks fluoridated tap water risk developing enamel fluorosis or discolored teeth, according to the New York State Department of Health (1).. Bureaucrats fail to effectively broadcast this vital information beyond their little-read websites which places babies at unnecessary risk of developing fluoride-damaged teeth.. Fluoride chemicals are added to tap water serving 12 million New Yorkers (8.4 million in NYC) in a failed effort to reduce tooth decay. Fluoridation costs NYC about $20 million yearly.(2). In 2006, the National Research Council (NRC) cautioned that infants can fluoride-overdose via reconstituted baby formula using optimally fluoridated water and risk growing white spotted, yellow, brown and/or pitted permanent teeth (enamel fluorosis). (3). Parents, who are concerned about the risk of enamel fluorosis, can mix liquid concentrate or powdered infant formula with water that is fluoride-free or contains low levels of fluoride.

You can safely use fluoridated tap water to prepare infant formula. Exposure to fluoride during infancy helps prevent tooth decay.. However, regularly mixing powdered or liquid concentrate infant formula with fluoridated water might increase your childs risk of developing faint white lines or streaks on the teeth (fluorosis) if these kinds of formula are your childs main source of food.. Fluorosis is a cosmetic issue that affects both baby teeth and permanent teeth while theyre forming under the gums. In young children, combined fluoride exposure from all sources contributes to fluorosis. This includes the fluoride in fluoridated water, foods and drinks made with fluoridated water, and fluoridated toothpaste and mouth rinses - especially if these products are swallowed. Fluorosis cant develop or worsen once permanent teeth break through the gums.. If youre concerned about fluorosis, consider ways to minimize your babys exposure to fluoride. For example, you might use ready-to-feed formula, ...
Moles are a common occurrence in many individuals in Newburgh. The dark color in moles is due to the melanin pigment. Why moles occur and how they develop is not well understood. The majority of moles are harmless and do not pose a health risk.
To reduce the risk of development of dental fluorosis, total fluoride intake in infancy and early childhood should be monitored and examined for signs of excessive fluoride exposure. The urinary fluoride/creatinine ratio (UF/Cr) in a spot urine sample could be a useful systemic fluoride exposure monitoring tool; replacing 24h urine collection. However, there are no reference value for UF/Cr corresponding to excessive systemic fluoride exposure in children. In this study, we took 158 simultaneously collected total daily fluoride intake and excretion data in children ,7 years from UK studies conducted by our team from 2002-2014. This study showed a strong positive linear relationship between total daily fluoride intake and UF/Cr, which suggests value in the use of a UF/Cr for estimation of fluoride intake in young children. This study has also established, for the first time, an upper reference value of a UF/Cr of 1.69 corresponding to excessive fluoride intake currently suggested as being ,0.07 ...
Researchers recruited mothers of newborn infants from eight Iowa hospital postpartum wards between 1992 and 1995 for their childrens participation in what would become known as the Iowa Fluoride Study, an investigation of dietary and non-dietary fluoride exposures, dental fluorosis and dental cavities.

damage, in children drinking water with over 2mg fluoride per liter.. -- liver function can be damaged without dental fluorosis. Dose-effect relationship between water fluoride levels and damage to liver and kidney functions in animals has been reported, the authors write. However, this is one of the few to do so in humans. The liver and kidneys are especially susceptible to fluoride toxicity, they write.. Paul Beeber, NYSCOF President says, 2 mg fluoride daily is very often exceeded from food, beverages, pharmaceuticals, and dental products. Clearly this is more evidence showing fluoridation is not only harmful, but unethical and immoral, says Beeber.. To prevent crippling skeletal fluorosis, the Environmental Protection Agency set 4 mg/L as the maximum fluoride contamination of drinking water. But this doesnt protect all Americans from all of fluorides adverse effects, according to a recent National Academy of Sciences (NAS) fluoride panel(2). After reviewing hundreds of studies over ...

The AI is based on a mean fluoride intake from the diet (including drinking water with NHMRC Drinking Water Guideline of 1.0 mg F/L) that effectively minimises dental caries. The previous AI (0.05 mg/kg body weight (bw)/day) for infants and children up to 8 years old age group was maintained. A change was made in 2017 in that the AI is not considered applicable to infants aged 0-6 months, as breast feeding is assumed for most infants. A new UL of 0.2 mg/kg bw/day, which minimises dental fluorosis of concern, was based on the 95th percentile of fluoride dietary intake assuming fluoridation of water at 1.9 mg/L. Estimated fluoride intakes from all sources (i.e., diet including water and other beverages, fluoridated toothpaste and/or supplements) in Australia and New Zealand for infants and children up to 8 years old were distributed around the AI but less than this new UL. This supports the continued use of fluorides in Australia including the fluoride level for drinking water and widespread use ...
Fluoride chemicals are added to public water supplies in a failed effort to reduce tooth decay in tap water drinkers.. Recently, the US Department of Health and Human Services recommended lowering optimal water fluoride levels to 0.7 ppm to decrease the epidemic of fluoride-discolored teeth (dental fluorosis) afflicting over 41% of adolescents. Many cities are complying, some consider ending fluoridation.. Attorney Paul Beeber, President, New York State Coalition Opposed to Fluoridation says water fluoride, along with fluoride-containing pesticide residues, is contaminating the food supply and harming our children. Clearly, artificial fluoridation must stop completely.. Fluoride is neither a nutrient nor required for healthy teeth. Studies show fluoride ingestion doesnt reduce tooth decay, says Beeber..

With respect to current and historical perspectives, the NAS committee noted that, on average, fluoride exposure from drinking water in fluoridated communities is near or exceeds the level that raises health concerns.[15] That is, virtually no margin of safety exists between levels of fluoride intended to be beneficial and those that may be harmful. This is in sharp distinction from the margin of safety when essential nutrients such as iodine, vitamin D, or vitamin C are added to food. In those cases, maximum potential intake is orders of magnitude lower than exposures that may have toxic effects. Population-wide monitoring of fluoride exposures in the U.S. is surprisingly inadequate. This is particularly disturbing since, despite vigorously recommending putting fluoride into drinking water, the CDC has failed to monitor systematically the levels of fluoride in the population -- despite steadily increasingly sources of fluoride, increasing dental fluorosis, and their well-known and highly ...
Since community water supplies and toothpastes usually contain fluoride, it is essential that children do not ingest too much. For this reason, children under the age of two should use an ADA-approved, non-fluoridated brand of toothpaste. Children between the ages of two and five years old should use a pea-sized amount of ADA-approved fluoridated toothpaste, on a clean toothbrush, twice each day. They should be encouraged to spit out any extra fluid after brushing. This part might take time, encouragement, and practice.. The amount of fluoride children ingest between the ages of one and four years old determines whether or not fluorosis occurs later. The most common symptom of fluorosis is white specks on the permanent teeth. Children over the age of eight years old are not considered to be at-risk for fluorosis, but should still use an ADA-approved brand of toothpaste.. Does my child need fluoride supplements ...
Beyond Pesticides, August 21, 2019) A birth cohort study in Canada found elevated levels of fluoride exposure during pregnancy are associated with lower IQ scores in 3 to 4-year-old children. This new research, published in the journal JAMA Pediatrics, builds on previous analyses that suggest high fluoride exposure is related to adverse effects to childrens neurodevelopment. Researchers recommend that pregnant mothers should reduce fluoride intake during pregnancy. Noting the controversy of the study, JAMA Pediatrics editor Dr. Dimitri Christakis said it was subjected to additional scrutiny for its methods and the presentation of its findings.. The Maternal-Infant Research on Environmental Chemicals (MIREC) program recruited pregnant mothers to participate in the study from 2008-2011. A total of 601 mother-child pairs from 6 major cities participated; 41% of them lived in cities with fluoridated municipal water. Exposure was measured through urine samples as well as self-reported maternal ...

Findings from our meta-analyses of 27 studies published over 22 years suggest an inverse association between high fluoride exposure and childrens intelligence. Children who lived in areas with high fluoride exposure had lower IQ scores than those who lived in low-exposure or control areas. Our findings are consistent with an earlier review (Tang et al. 2008), although ours more systematically addressed study selection and exclusion information, and was more comprehensive in a) including 9 additional studies, b) performing meta-regression to estimate the contribution of study characteristics as sources of heterogeneity, and c) estimating pooled risk ratios for the association between fluoride exposure and a low/marginal Ravens test score.As noted by the NRC committee (NRC 2006), assessments of fluoride safety have relied on incomplete information on potential risks. In regard to developmental neurotoxicity, much information has in fact been published, although mainly as short reports in Chinese ...
Fluoride intake in high doses has toxic effects on various organs. Chronic fluorosis results in tubular degenerations, inflammation, fibrosis, parenchymatous nephritis, cloudy swellings, and dilations of convoluted tubules. In addition to these effects, fluoride causes deteriorative effects on the skeleton, teeth, and soft tissues. The goal of this study was to examine the impacts of chronic fluorosis on the liver tissues of mice. Materials and methods: One control group and 3 experimental groups, each group consisting of 4 male and 4 female mice, were formed to conduct the experiment. A stock solution including 2000 ppm fluoride was prepared by solving 4.44 g of NaF in 1 L of distilled water. Water with 10, 20, and 40 ppm fluoride was obtained by diluting the stock solution to give to the animals. Animals in the control group had free access to tap water with 0.3 ppm fluoride.

NRC in 2006. It has been 10 years since the NRC concluded that the MCLG for fluoride be lowered, but EPA has yet to do so. Further, despite the voluminous post-2006 research on neurotoxicity, and despite the Safe Drinking Water Acts mandate that EPA protect against known or anticipated adverse effects,EPAs Office of Water (EPA OW) has indicated that it will not be considering neurotoxicity as an endpoint of concern when promulgating the new MCLG. Instead, in December 2010, EPA OW established a reference dose for fluoride based solely on severe dental fluorosis. EPA OW justified this decision on the grounds that NRCs 2006 review did not draw firm conclusions about the public health relevance of fluoride neurotoxicity. But nowhere in EPA OWs risk assessment did it account for the neurotoxicity research published subsequent to NRCs review, despite the many studies on neurotoxicity sent to them. ...
Response to North article of 10/3/2017 In a recent Lund Report, commenter Rick North stated a myriad of half-truths in regard to the public health initiative of water fluoridation. So, lets sort things out, and bring the issue back into reality

Will the U.S. EPA ban water fluoridation after they have received a petition detailing the risks of water fluoridation to human health?
A couple of weeks ago, the U.S. admitted there was too much fluoride in water, resulting in an increase in cases of mild dental fluorosis among children. Days later, an editorial in the Washington Post examined the risk of cavities from drinking filtered and bottled water that doesnt contain fluoride. With all of this confusion, its hard to determine the best way to ensure healthy teeth and bones for all. While reading the Washington Post article, I couldnt help but think it was a little biased. After all, the writer expresses that her concerns over drinking filtered water arrived while she was visiting her dentist who told her about the supposed dangers of not drinking fluoridated water. Well, of course your dentist is going to tell you that fluoride is necessary and good for you. One writer, in response to this article, suggested that it comes off as an ADA propaganda piece, and I would have to agree. But if fluoride is not the solution to cavities, then what is?. Two interesting ...

A new study in the Journal of Dental Research finds bone fluoride levels are not associated with osteosarcoma, a rare bone cancer more prevalent in males.
The Fluoride Action Network (FAN), along with a coalition of environmental and public health groups has filed a complaint in the U.S. District Court for the Northern District of California against the U.S. Environmental Protection Agency (EPA) in response to their denial of a petition under Section 21 of the Toxic Substances Control Act (TSCA) seeking a ban on water fluoridation.. This lawsuit is an unprecedented opportunity to end the practice once and for all in the U.S., and potentially throughout the world, based on the well-documented neurotoxicity of fluoride. You may read the official complaint here. According to FANs attorney and adviser, Michael Connett: This case will present the first time a court which will consider the neurotoxicity of fluoride and the question of whether fluoridation presents an unreasonable risk under the Toxic Substances Control Act (TSCA). And, in contrast to most other legal challenges of Agency actions, TSCA gives us the right to get the federal court to ...
Unlike extrinsic discolorations that occur on the surface, intrinsic discoloration is due to the presence of chromogenic (coloured) material within enamel or dentin, incorporated either during tooth developing (odontogenesis) or after eruption. This type of stain can be divided into 2 groups, preeruptive and posteruptive. The most common type of pre-eruptive staining is endemic fluorosis caused by excessive fluoride ingestion during tooth development. Post-eruptive stain usually associated with pulp problems such as pulp necrosis, or root canal material. Generally, intrinsic stain can be divided into:. Systemic causes are. ...
