To define the relationship between ionic fluoride concentration in the serum of workers and the amount of hydrofluoric acid (HF) in the work environment, pre-and postshift serum and urine samples of 142 HF workers and 270 unexposed workers were examined. The maximum and minimum concentrations of HF in the air in each workshop varied from the mean by less than 30%. The preexposure levels of serum and urinary fluoride in HF workers were higher (P , 0.001) than the control values. This suggests that fluoride excretion from the body continues for at least 12h. The postshift serum and urinary fluoride concentrations of these workers were significantly higher (P , 0.001) than the preshift concentrations. A good correlation (r = 0.64) was obtained between postshift serum fluoride and postshift urine fluoride. There was a linear relationship between mean serum fluoride concentration and HF concentration in the workshop. A mean fluoride concentration of 82.3 micrograms/l with a lower fiducial limit (95%, ...
Though the concentration of fluoride in drinking water in Noapara was much higher than that in Kamdebpur, Chalk Atla and Junidpur, the urinary fluoride concentration in subjects of Noapara did not differ much. The predominance of severe skeletal and dental fluorosis in subjects of Noapara can probably be linked to high fluoride exposure but relatively less excretion (as evident from urinary fluoride levels). Interestingly, despite low fluoride (within the permissible limit) levels in drinking water, the urinary fluoride concentration of individuals residing in Kamdebpur village was found to be very high (highest 7.3 ppm). Again, 69.22% of the people surveyed from Kamdebpur were found to suffer from different forms of dental and skeletal fluorosis (Figure 1c, d and g). Thus, the evidence of fluorosis and elevated urinary fluoride concentration was not positively correlated with drinking water fluoride level in this sample population. In Junidpur, fluoride concentration in both drinking water and ...
Fluoride toxicity is a condition in which there are elevated levels of the fluoride ion in the body. Although fluoride is safe for dental health at low concentrations, sustained consumption of large amounts of soluble fluoride salts is dangerous. Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg/kg elemental fluoride/kg body weight). Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2-0.3 mg/kg or 10 to 15 mg for a 50 kg person) than lethal doses. Although it is helpful for dental health in low dosage, chronic exposure to fluoride in large amounts interferes with bone formation. In this way, the most widespread examples of fluoride poisoning arise from consumption of ground water that is abnormally fluoride-rich. For optimal dental health, the World Health Organization recommends a level of fluoride from 0.5 to 1.0 mg/L (milligrams ...
Fluoride 1995; 28(2):75-86 Amelioration of fluoride toxicity in some accessory reproductive glands and spermatozoa of rat. Chinoy NF, Narayana MV, Dalal V, Rawat M, Patel D. Reproductive Endocrinology and Toxicology Unit, School of Sciences, Gujarat University, Ahmedabad 380 009, India. Summary: Sodium fluoride (NaF) at a dose of 10 mg/kg body weight was administered orally to male rats (Rettus norvegicus) daily for 30 and 50 days to evaluate the effect of the physiology of some sex accessory glands and sperm functions. The effects of withdrawal upon cessation of NaF ingestion, and of administering ascorbic acid (AA) and/or calcium (Ca++) along with NaF, were also investigated. The results revealed that the NaF treatment caused a significant elevation in serum fluoride levels with a simultaneous rise in Ca++ levels. This could be attributed to the formation of a calcium fluoride complex leading to calcium accumulation. The treatment resulted in structural and metabolic alterations in sperm, ...
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 ...
The aim of the present study was to determine the toxicity of fluorides on energy metabolism in muscles of the Helix aspersa maxima snail. Qualitative and quantitative analysis of purine compounds was performed in slices of foot from mature snails with high-performance liquid chromatography. Fluoride concentrations were measured using an ion-selective electrode and gas chromatography. The results show that exposure to fluoride pollution was accompanied by a statistically significant increase in fluoride concentrations in soft tissues. This effect was already noticeable with the smallest fluoride dose. Accumulation was greatest in the shell. There is a significant and positive correlation between fluoride concentrations in foot muscles and guanine and inosine nucleotides or uridine content. The content of low-energy guanylate, inosylate and oxypurine in foot muscles significantly increased with rising dose of fluoride. The difference as compared with controls was significant only for the highest ...
In our age of increasing radioactivity and toxic poisoning specifically with fluoride,[1] chlorine, bromide, and even mercury, iodine is a necessary mineral.. Iodine is extremely important since the cells need it to regulate their metabolism. Without it, people are known to suffer from swollen glands in the throat, thyroid diseases, increased fluoride toxicity, decreased fertility rates, increased infant mortality rates, and (with severe deficiency) mental retardation. It has been theorized that iodine deficiency is a causal factor of ADHD in babies of iodine-deficient mothers.. Iodine intake immediately increases the excretion of bromide, fluoride, and some heavy metals including mercury and lead. Bromide and fluoride are not removed by any other chelator or detoxifying technique.. Dr. Kenezy Gyula Korhaz states that iodine chelates heavy metals such as mercury, lead, cadmium, aluminum, and halogens such as fluoride and bromide, thus decreasing their iodine-inhibiting effects,[2] especially of ...
Fluoride Is a Neurotoxic, Endocrine Disrupting Drug Fluoride is an endocrine disrupting, neurotoxic, and bone-weakening substance that the Food and Drug Administration (FDA) defines as a drug when used to prevent disease, because unlike the minerals we need (e.g. calcium), humans have no known physiological requirement for fluoride. Sodium fluoride, long known as an effective roach poison, is added to tablets and drops (i.e., fluoride supplements) for the purpose of preventing tooth decay. But because of fluorides toxicity, you cannot purchase fluoride supplements over-the-counter; they can only be dispensed by prescription under the supervision of a doctor. In short, sodium fluoride is not a nutritional supplement; it is a prescription drug, and a dangerous one. Although fluoride drugs have been prescribed for over 50 years, the FDA recently announced that marketing fluoride drops and tablets for cavity prevention violates federal law, because FDA has never approved these products as ...
Different fluoride formulations may have different effects on caries prevention. It was the aim of this clinical study to assess the fluoride content, provided by NaF compared to amine fluoride, in saliva and plaque. Eight trained volunteers brushed their teeth in the morning for 3 minutes with either NaF or amine fluoride, and saliva and 3-day-plaque-regrowth was collected at 5 time intervals during 6 hours after tooth brushing. The amount of collected saliva and plaque was measured, and the fluoride content was analysed using a fluoride sensitive electrode. All subjects repeated all study cycles 5 times, and 3 cycles per subject underwent statistical analysis using the Wilcoxon-Mann-Whitney test. Immediately after brushing the fluoride concentration in saliva increased rapidly and dropped to the baseline level after 360 minutes. No difference was found between NaF and amine fluoride. All plaque fluoride levels were elevated after 30 minutes until 120 minutes after tooth brushing, and decreasing after
Medical Science Research 1997; 25 (2): 97-100. Fluoride toxicity in the testis and cauda epididymis of guinea pig and reversal by ascorbate. Chinoy NJ, Patel BC, Patel DK, Sharma AK.. Author Address: Zoology Dep., Sch. Sciences, Gujarat Univ., Ahmedabad 380009, India. Effects of sodium fluoride (NaF) (30 mg kg-1 body weight) and ascorbic acid ingestion along with sodium fluoride for 30 days each were studied to evaluate its possible role as an ameliorative agent on functions of reproductive organs and spermatozoa of the fluorotic guinea pig. The cauda epididymal spermatozoa were highly sensitive to the effects of sodium fluoride as their structural and metabolic alterations led to marked decreases in their motility, live:dead ratio and sperm mitochondrial activity index but increases in sperm abnormalities and alterations in sperm membrane phospholipids, particularly phosphatidylinositol and phosphatidyl serine. The activities of ATPase and succinate dehydrogenase as well as glutathione levels ...
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 ...
When the National Research Council of the National Academies reviewed this topic in their 507-page report Fluoride in Drinking Water: A Review of EPAs Standards published in 2006, only 5 of the 24 IQ studies were available in English. Even so the panel found the link between fluoride exposure and lowered IQ both consistent and plausible. According to Tara Blank, Ph.D., the Science and Health Officer for the Fluoride Action Network, This should be the study that finally ends water fluoridation. Millions of American children are being exposed unnecessarily to this neurotoxin on a daily basis. Who in their right minds would risk lowering their childs intelligence in order to reduce a small amount of tooth decay, for which the evidence is very weak. (see The Case Against Fluoride, Chelsea Green, October 2010) - This just in from Dr. Paul Connett (The Case Against Fluoride) and the Fluoride Action Network: A very important study, titled Serum Fluoride Level and Childrens Intelligence ...
In young children, especially those under the age of 6, too much fluoride can be toxic. Parents need to be vigilant in monitoring their childrens brushing habits and in keeping all forms of fluoride out of reach. Excess fluoride can also produce defects in tooth enamel that appear as barely noticeable white specks or streaks, or even worse, as brown spots. This condition, known as fluorosis, is usually the result of drinking water that is overly fluoridated (i.e., well water).. If you have questions or concerns about the fluoride content in your local drinking water or youre wondering if you or your child can benefit from fluoride treatments, call Sarah Belderes DDS and we will be happy to address your concerns and answer any questions that you might have.. ...
Systemic fluoride is delivered to the tooth surface via the bloodstream. Systemic fluoride can be derived from a food source, water source, or dietary supplements (pill, tablet, lozenge, drop). Fluoridated water is an effective way to reduce the problem of dental decay. It has been shown that fluoridated water and dietary supplements can reduce up to 60% of tooth decay.. Some water supplies naturally contain fluoride, but for others fluoride is added to the water supply. If you would like to know if your communitys water supply contains fluoride, call your local water or health department.. Children from birth to 16 years of age will benefit the most from systemic fluoride. Sixteen is currently the age at which the American Dental Association recommends children can discontinue fluoride vitamin supplements. This is because when fluoride is ingested, it circulates through the bloodstream and into developing teeth. The fluoride is then built into the enamel structure of the developing tooth, ...
Fluoride is the most effective agent available to help prevent tooth decay. It is a mineral that is naturally present in varying amounts in almost all foods and water supplies. The benefits of fluoride have been well known for over 50 years and are supported by many health and professional organizations.. Fluoride works in two ways:. Topical fluoride strengthens the teeth once they have erupted by seeping into the outer surface of the tooth enamel, making the teeth more resistant to decay. We gain topical fluoride by using fluoride containing dental products such as toothpaste, mouth rinses, and gels. Dentists and dental hygienists generally recommend that children have a professional application of fluoride twice a year during dental check-ups.. Systemic fluoride strengthens the teeth that have erupted as well as those that are developing under the gums. We gain systemic fluoride from most foods and our community water supplies. It is also available as a supplement in drop or gel form and can ...

To optimise the quality of dental research involving fluoride assay and minimise between-laboratories fluoride analysis inconsistencies, standardised fluoride analysis techniques should be developed and tested. The aim of this collaborative project was to compare potential methods for fluoride analysis in microlitre-volume plasma samples containing nano-gram amounts of fluoride. The study sites comprised four internationally recognised laboratories with track record expertise in fluoride analysis: Teesside University (UK), University of São Paulo (Brazil), Newcastle University (UK), and Indiana University (US). All collaborative partners analysed a set of standardised biological samples as well as plasma using the established HMDS-diffusion method, a micro-diffusion method and known-addition technique. The results showed that the known-addition technique could be a suitable alternative for measurement of fluoride in plasma with microlitre-volume ...

Previous studies have shown a correlation between fluoride concentrations in urine and community water fluoride concentrations. However, there are no studies of the relationship between community water fluoridation, urine, serum, and amniotic fluid fluoride concentrations in pregnant women in the US. The aim of this study was to determine the relationship between maternal urine fluoride (MUF), maternal urine fluoride adjusted for specific gravity (MUFSG), maternal serum fluoride (MSF), amniotic fluid fluoride (AFF) concentrations during pregnancy, and community water fluoridation in Northern California. Archived samples of urine, serum and amniotic fluid collected from second trimester pregnant women in Northern California from 47 different communities in Northern California and one from Montana (n = 48), were analyzed for fluoride using an ion specific electrode following acid microdiffusion. Womens addresses were matched to publicly reported water fluoride concentrations. We examined whether fluoride
The fluoride dose ingested by young children may be overestimated if based on levels of total fluoride (TF) rather than levels of bioavailable fluoride (total soluble fluoride-TSF) in toothpaste. The aim of the present study was to compare doses of fluoride intake based on TF and TSF. Fluoride intake in 158 Brazilian children aged three and four years was determined after tooth brushing with their usual toothpaste (either family toothpaste (n = 80) or childrens toothpaste (n = 78)). The estimated dose (mg F/day/Kg of body weight) of TF or TSF ingested was calculated from the chemical analysis of the toothpastes. Although the ingested dose of TF from the family toothpastes was higher than that from the childrens toothpastes (0.074 ± 0.007 and 0.039 ± 0.003 mg F/day/Kg, respectively; p < 0.05), no difference between types of toothpaste was found regarding the ingested dose based on TSF (0.039 ± 0.005 and 0.039 ± 0.005 mg F/day/Kg, respectively; p > 0.05). The fluoride dose ingested by

The method of duplicating food samples (double plate approach) for determination of daily fluoride intake has the advantage of greater accuracy than indirect calculations of intake using diets and table values of the fluoride content in the most frequent components of food and beverages in a childs diet. When tracing fluoride sources in a childs diet, assuming that up to 80% of fluoride in the diet of preschool children comes from drinks [7, 14], the authors focused their attention on the fluoride content of bottled water as public water supplies in the centres concerned, where the samples of childs diet were collected, contained 0.08-0.15 ppm fluoride and the provision of bottled water for children is very popular. The bottled table mineral water available locally was richer in fluoride (, 0.7 ppm) and is obligatorily labelled as not suitable for children up to 7 years. Bottled mineral water is given to children irregularly and rarely [14, 15]. In an attempt to collect data on the ...
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

Introduction: Fluorosis an endemic problem affects many tissues including endocrine glands such as thyroid. Iodine deficiency remains the most common cause of primary hypothyroidism worldwide. Fluoride and iodine are both halogens. Fluoride, the negative ion of the element fluorine, easily displaces iodine in the body because it is much lighter and therefore more reactive. Few studies have reported no relationship between serum fluoride levels and thyroid disorders, while others have reported decreased serum thyroid hormone levels are associated with increased fluoride levels in hypothyroidism. Goiter and hypothyroidism are known to be caused by iodine deficiency. However, it has also been found to occur in areas where there are adequate supplies of iodine, but where there is an excess fluoride in the water. The present study was conducted to assess the fluoride status in newly diagnosed cases of hypothyroidism. Aims & objectives 1) To assess the fluoride status in the patients of hypothyroidism ...

Fluoridated community drinking water and fluoride toothpaste are the most common sources of fluoride in the United States and are largely responsible for the low risk for dental caries for most persons in this country. Persons at high risk for dental caries might require more frequent or more concentrated exposure to fluoride and might benefit from use of other fluoride modalities (e.g., mouthrinse, dietary supplements, and topical gel, foam, or varnish). The effects of each of these fluoride sources on dental caries and enamel fluorosis are described. Fluoridated Drinking Water and Processed Beverages and Food Fluoridated drinking water contains a fluoride concentration effective for preventing dental caries; this concentration can occur naturally or be reached through water fluoridation, which is the controlled addition of fluoride to a public water supply. When fluoridated water is the main source of drinking water, a low concentration of fluoride is routinely introduced into the mouth. Some ...
The reactivity of potassium fluoride with wild-type cytochrome c peroxidase (CcP) and a mutant of cytochrome c peroxidase in which the distal histidine (His-52) is replaced with leucine [CcP(H52L)] has been studied from pH 4 to 8 in phosphate buffer at 0.1 M ionic strength. The spectrum of the fluoride complex of CcP(H52L) has been characterized. The kinetics of fluoride binding and the equilibrium constant for complex formation for both wild-type CcP and CcP(H52L) have been determined as a function of pH. The results of this study indicate that HF binds to wild-type CcP when the distal histidine is unprotonated. However, the association rate constant for fluoride binding to CcP(H52L) is only a factor of ten slower than binding to CcP at pH 5.5 and about the same at pH 8.0. A possible explanation is that another group, such as Arg-48 or the heme-bound hydroxide group in CcP(H52L), provides a function similar to that of His-52 in wild-type CcP. A major effect of the H52L mutation is to increase ...
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 ±
An Assessment of Bone Fluoride and Osteosarcoma appears July 28 online and was designed to determine if bone fluoride levels were higher in individuals with osteosarcoma.. The case-control study was led by Dr. Chester Douglass of the Harvard University School of Dental Medicine and identified patients from the orthopedic departments of nine U.S. hospitals from 1993-2000. The researchers studied samples from incident cases of primary osteosarcoma and a control group of patients with newly-diagnosed malignant bone tumors. They also analyzed specimens of tumor-adjacent bone and iliac crest bone for fluoride content. They found that there was no significant difference in bone fluoride levels between cases and controls.. The controversy over whether there is an association between fluoride and risk for osteosarcoma has existed since an inconclusive animal study 20 years ago, said Dr. Helen Whelton, vice president, International Association for Dental Research. Numerous human descriptive and ...

Besides human dental and skeletal fluorosis, drinking water above permissible levels of fluoride is known to cause a wide range of adverse health effects. In this study, the adsorption of Fluoride from aqueous solution onto pretreated zeolite has been studied by using batch test. The large surface area of natural zeolite (i. e., clinoptilolite from Miyaneh region, Iran) was utilized to create active sites for fluoride sorption by exchanging Na+-bound zeolite with Fe3+ and Al3+ ions. In this study, the effects of variables such as contact time, and Fluoride concentration have been investigated. Since the chemistry quality of groundwater varies from point to point, the effects of pH and electrolytes such as bicarbonate, chloride and sulfate on fluoride uptake are studied too. The performances of the Fluoride adsorption with the natural zeolite (i. e., non modified zeolite) were compared with the pretreated zeolite. Factors from the solution chemistry that affected fluoride removal from water were the

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 ...
Its important to recognize that fluoride is not only found in water and toothpaste. Fluoride is an important component of our soil, and is incorporated in varying amounts into our food and drinks in the manufacturing process. This makes it extremely difficult to regulate. Toothpastes can contain anywhere from 1000ppm to 1500ppm of fluoride and soft drinks were found to have fluoride levels ranging from 0.02 to 1.28ppm, with an average of 0.60ppm. Although conclusive research is not available, the possible dangers of excess fluoride intake warrant additional study and avoiding the use of products that contain large amounts of fluoride. Products that may contain large amounts of fluoride include soft drinks, teas and toothpaste. A fluoride intake of 0.05-0.07 mg/kg body weight/day has been suggested as being optimal.16 A Brazilian study looking at fluoride intake from toothpaste and dietary sources found that toothpaste alone contributes to roughly 80% of the recommended fluoride intake.16 The ...
A review of evidence-based literature indicates incomplete evidence for the efficacy of most measures currently used for caries prevention, with the exception of fluoride varnishes and the use of fluoride-based interventions for patients with hyposalivation. Not all fluoride agents and treatments are equal. Different fluoride compounds, different vehicles, and vastly different concentrations have been used with different frequencies and durations of application. These variables can influence the clinical outcome with respect to caries prevention and management. The efficacy of topical fluoride in caries prevention depends on a) the concentration of fluoride used, b) the frequency and duration of application, and to a certain extent, c) the specific fluoride compound used. The more concentrated the fluoride and the greater the frequency of application, the greater the caries reduction. Factors besides efficacy, such as practicality, cost, and compliance, influence the clinicians choice of preventive

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, ...

Aluminum fluoride reported oral animal lethal dose (LD50) is 0.1 g/kg.[17] Repeated or prolonged inhalation exposure may cause asthma, and may have effects on the bone and nervous system, resulting in bone alterations (fluorosis), and nervous system impairment.[18]. Many of the neurotoxic effects of fluoride are due to the formation of aluminum fluoride complexes, which mimic the chemical structure of a phosphate and influence the activity of ATP phosphohydrolases and phospholipase D. Only micromolar concentrations of aluminum are needed to form aluminum fluoride.[19]. Human exposure to aluminum fluoride can occur in an industrial setting, such as emissions from an aluminum reduction processes,[20] or when a person ingests both a fluoride source (e.g., fluoride in drinking water or residue of fluoride-based pesticides) and an aluminum source; sources of human exposure to aluminum include drinking water, tea, food residues, infant formula, aluminum-containing antacids or medications, deodorants, ...
A microelectromechanical systems (MEMS) device utilizing an aluminum fluoride layer as an etch stop is disclosed. In one embodiment, a MEMS device includes a first electrode having a first surface; and a second electrode having a second surface facing the first surface and defining a gap therebetween. The second electrode is movable in the gap between a first position and a second position. At least one of the electrodes includes an aluminum fluoride layer facing the other of the electrodes. During fabrication of the MEMS device, a sacrificial layer is formed between the first and second electrodes and is released to define the gap. The aluminum fluoride layer serves as an etch stop to protect the first or second electrode during the release of the sacrificial layer.
Monofluorophosphate salts, especially sodium monofluorophosphate (Na 2 PO 3 F), when added to various industrial water systems in concentrations between 0.1 mg/L and 50 mg/L, significantly reduce the amount of calcium carbonate scale which is formed on heat exchange and other metallic surfaces of such systems. Monofluorophosphate salts, especially sodium monofluorophosphate, when added to various water systems in concentrations between 0.1 mg/L and 50 mg/L also stabilizes soluble manganese ion and its reaction products, i.e., primarily MnO 2 , in desirable forms and reduced particle sizes. Monofluorophosphate salts, especially sodium monofluorophosphate, when added to various water systems in concentrations between 1 mg/L and 500 mg/L also stabilizes soluble iron ion and its reaction products, i.e., primarily Fe 2 O 3 .
This study aimed to characterize fluoride-induced alterations in dentin mineralization within a dentin-pulp organ culture system. Tooth sections derived from male Wistar rat incisors were cultured in Trowel-type culture for 14 days, in the presence of 0 mM, 1 mM, 3 mM and 6 mM sodium fluoride. Tooth sections were processed and analyzed for uptake of fluoride, its subsequent effect on dentin mineralization by tetracycline hydrochloride incorporation and mineral composition, expressed as calcium/phosphorous (Ca/P) ratios. Tetracycline hydrochloride incorporation was demonstrated to decrease with increased fluoride exposure, accompanied by significant increases in both Ca/P ratios and fluoride incorporation. These findings provide further evidence that the established alterations in dentin formation during fluorosis are a consequence of disruption to the mineralization process, and provide a model system with which to investigate further the potential role the extracellular matrix plays in inducing ...

There are 2 comments on the hsionline.com story from Sep 24, 2012, titled Public water fluoridation is a hot issue in two large U.S. communities. In it, hsionline.com reports that: A few days ago, I told you about the Portland, Oregon, fluoride controversy. City officials claim that public water fluoridation is the only solution to the local dental crisis. So when it came time for a vote of the City Council last week, how do you suppose that went? Mayor Sam Adams said, The science is on the side of fluoridation. A recent Harvard study linked high levels of water fluoridation to lower IQ scores in children. And even the CDC admits that excess fluoride exposure causes dental discoloration or damage in about 40% of U.S. children. There s science for you.

The recommended level of fluoride in drinking water is currently between 0.7 and 1.2 mg/L, so treatment may be advisable for higher fluoride levels. It is only necessary to treat water used for drinking and cooking for high fluoride levels; water used for washing, showering and other uses need not be treated. If treatment is not desirable or an option, one may consider buying bottled water or using water from an alternate source for drinking and cooking.. Treatment methods to remove fluoride from drinking water include activated alumina filters, distillation, reverse osmosis, and ion exchange. Because the activated alumina filters, distillation and reverse osmosis treatment options treat a relatively small volume of water at any one time, they can be costly, and storage space for treated water may be required. As a result, these devices are typically considered point-of-use treatment options and may only be practical for installation at one faucet. Ion exchange treatment systems can be either ...

Purpose: The purpose of this study was to assess Maryland dental hygienists knowledge, practices and opinions regarding dental caries prevention and early detection.. Methods: A 30 item survey was mailed to 1,258 Maryland dental hygienists. Two follow-up mailings and email reminders were sent.. Results: The response rate was 43% (n=540). Nearly all respondents were female (98%), and 58% practiced in solo settings. Knowledge and certainty of knowledge were moderate: sealants are needed regardless of topical fluoride use (55% certain, 40% less certain), newly erupted permanent molars are the best candidates for sealants (54%, 36%) and professionally applied fluorides are desirable in areas without fluoridated water (55%, 36%). Fewer were certain that incipient lesions can be remineralized before cavitation (23%, 69%), and dilute, frequently administered fluorides are more effective in caries prevention than concentrated, less frequently administered fluorides (6%, 24%). Opinions regarding ...

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 ...
Fluoride (F) varnishes are effective in preventing caries and reducing dentin sensitivity. The addition of calcium (Ca) and phosphate (PO4) salts may influence the F release rate and also induce formation of calcium/phosphate/fluoride as persistent F reservoirs. The hypothesis is that F release rate can be optimized with the F content and the addition of Ca and PO4 salts. Objectives: To study the effect of the F content and the Ca and PO4 salts on the ion release and precipitation of F varnishes. Methods: The varnish containing 1670 ppm or 22600 ppm fluoride with or without Ca salt (10%) and PO4 salt (5.8%) was painted on a 2x2 cm plastic substrate and immersed in a 0.03 mol/L NaCl solution (n=3). The released ions were measured with pH, Ca, and F electrodes under slow stirring at 22 oC for 3 days. The concentrations of Ca and PO4 were analyzed by spectrophotometric methods. The precipitated calcium phosphate fluoride was characterized with X-ray Powder Diffraction and Scanning Electron ...

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 ...
The main finding of this study was that exhaled NO concentrations in non-smoking potroom workers were 63% higher than in non-smoking control subjects recruited from the same plant. The two groups were otherwise comparable for occurrence of asthma-like symptoms and use of β2-agonists. No subject in either group used corticosteroids. The potroom workers were somewhat younger than the controls (mean age 40 v 46 years), but concentrations of exhaled NO have not been shown to vary with age.12 Although the exhaled NO concentration in the non-smoking potroom workers was not as high as that found in symptomatic asthmatic subjects, it was comparable to the concentration observed in atopic subjects with bronchial hyperresponsiveness.18 In smokers, we found no difference in exhaled NO between potroom workers and controls. This may be because chronic cigarette smoking itself decreases exhaled NO, both in healthy19 and in asthmatic subjects.20 In mildly asthmatic subjects, the effect of smoking on exhaled ...

It is imperative to the health of all citizens to gain knowledge about what they are consuming on a daily basis. Fluoride chemicals added to Floridas water supply were never safety-tested and are lead- and arsenic-laced industrial waste-products (hydrofluosiclicic acid). Even in small quantities, sodium fluoride is a deadly poison to which no effective antidote has been found. Every exterminator knows that it is the most efficient rat-killer. ... Sodium fluoride is entirely different from organic calcium-fluoro-phosphate needed by our bodies and provided by nature to build and strengthen our bones and our teeth. This organic calcium-fluoro-phosphate, derived from proper foods, is an edible organic salt, insoluble in water and assimilable by the human body, whereas the non-organic sodium fluoride used in fluoridating water is instant poison to the body and fully water soluble.In its advanced stages, fluorosis can resemble a multitude of bone/joint diseases. According to the National Toxicology ...

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 ...
