Dental workplace exposure and effect on fertility. (1/195)

OBJECTIVES: This study assessed occupational exposure in dental surgeries on the basis of the reported use of dental materials and techniques and applied waiting-time-to-pregnancy methodology to study fertility in relation to the occupational exposure. METHODS: Data were collected retrospectively using a self-administered postal questionnaire addressing the occupational and reproductive history of the participants. The study groups consisted of 558 female dental surgeons and 450 high school teachers that had given birth in Norway to at least 1 living child. The present study comprised data from a total of 1408 pregnancies. The effects of practicing dentistry and of the given workplace exposure on fertility were analyzed with the discrete proportional hazard regression method. RESULTS: Most of the female dental surgeons were using amalgam for fillings during the period they tried to conceive, and 1/3 placed more than 50 fillings a week. Tooth-colored fillings were in limited use. Prior to 75% of the pregnancies, the dental surgeons reported handling chloroform-based root canal sealers. Forty percent of the dental surgeons were daily exposed to disinfectants containing ethanol and benzene. No difference was found in fertility between the dental surgeons and the high school teachers. Exposure to mercury, chloroform, and benzene was not associated with decreased fertility, except for a possible effect of mercury in the last pregnancy of multiparous dental surgeons. CONCLUSIONS: Occupational exposures had no clear adverse effects on fertility among the female dental surgeons studied.  (+info)

Cadmium, mercury, and lead in kidney cortex of the general Swedish population: a study of biopsies from living kidney donors. (2/195)

Cadmium, mercury, and lead concentrations were determined in deep-frozen kidney cortex biopsies taken from 36 living, healthy Swedish kidney donors (18 males and 18 females), who were 30-71 (mean 53) years of age. Information about occupation, smoking, the presence of dental amalgam, and fish consumption could be obtained for 27 of the donors. The samples (median dry weight 0.74 mg) were analyzed using inductively coupled plasma mass spectrometry, and the results were transformed to wet-weight concentrations. The median kidney Cd was 17 micrograms/g (95% confidence interval, 14-23 micrograms/g), which was similar in males and females. In 10 active smokers, the median kidney Cd was 24 micrograms/g, and in 12 who never smoked, it was 17 micrograms/g. The median kidney Hg was 0.29 micrograms/g, with higher levels in females (median 0.54 micrograms/g) than in males (median 0.16 micrograms/g). Subjects with amalgam fillings had higher kidney Hg (median 0.47 micrograms/g, n = 20) than those without dental amalgam (median 0.15 micrograms;g/g, n = 6), but kidney Hg was below the detection limit in some samples. Nearly half of the samples had kidney Pb below the detection limit. The median kidney Pb was estimated as 0. 14 micrograms/g. This is the first study of heavy metals in kidney cortex of living, healthy subjects, and the results are relatively similar to those of a few previous autopsy studies, indicating that results from autopsy cases are not seriously biased in relation to kidney metal concentrations in the general population. Cd concentrations in those who never smoked were relatively high, indicating considerable Cd intake from the diet in Sweden. The effect of dental amalgam on kidney Hg was as expected, although the reason for the difference in Hg levels between males and females is unclear.  (+info)

Resistance to mercury and antimicrobial agents in Streptococcus mutans isolates from human subjects in relation to exposure to dental amalgam fillings. (3/195)

Resistance to cefuroxime, penicillin, tetracycline, and mercury is reported for 839 Streptococcus mutans isolates from 209 human study subjects. The MICs of these drugs did not differ for isolates from one dental amalgam group and two nonamalgam subsets: a group with no known exposure to amalgam and a group whose members had their amalgam fillings removed.  (+info)

Strength and microstructure of gallium alloys. (4/195)

This study investigated the physical and mechanical properties and the microstructure of four different gallium alloys. For all gallium alloys, the compressive strengths measured at one hour (86-223 MPa) and 24 hours (265-286 MPa) after specimen preparation were found to be well within the range exhibited by many high-copper amalgams. The creep values and dimensional change of the gallium alloys were comparable to those of leading amalgams, except for the dimensional change value of one alloy. The set gallium alloys consisted of a multi-phase structure including beta-Sn, CuGa2, In4Ag9, Ag72Ga28, and Ga5Pd (except for one product that did not contain Pd) that was more complicated than the structure of dental amalgams. Although the gallium alloys had physical and mechanical properties comparable to those of high-copper amalgams, the microstructure, coupled with the instability of the element gallium itself, could make these materials more prone to corrosive attack compared to amalgams.  (+info)

Management of extensive carious lesions in permanent molars of a child with nonmetallic bonded restorations--a case report. (5/195)

The badly decayed molar teeth of a 12-year-old were restored using resin composite and ceramic restorations. The maxillary first left permanent molar, which had an extensive carious lesion that had destroyed most of the coronal hard tissues of the tooth, was restored to shape and function with a heat-treated resin composite onlay restoration. The restoration was followed up for two years. The mandibular right first molar had a failing large amalgam restoration with extensive recurrent caries. After a three-month period of pulp-capping, the tooth was restored with a bonded ceramic onlay restoration. A nine-month follow-up of this restoration is provided. The maxillary right first molar, which also had a failing large amalgam/resin composite restoration, was restored with a direct resin composite restoration. Under traditional treatment regimens, these extensive cavities would have been treated using more invasive procedures such as pin-retained restorations or elective root canal therapy, post placement, core build-up and crowning. Bonded non-metallic restorations avoid the trauma, time and cost that accompany such extensive procedures and offer a more conservative approach.  (+info)

Mercury evaporation from amalgams with varied mercury contents. (6/195)

This study examined the relationship between mercury content and mercury evaporation from amalgams during setting. Two different types of commercial high-copper amalgams (single composition and admixed types) were used. Cylindrical specimens of each amalgam were prepared with five different mercury contents according to ADA Specification No.1. Specimens were also prepared by hand condensation. Mercury evaporation from amalgam specimens maintained at 37 degrees C was measured using a gold film mercury analyzer from 10 min after the end of trituration until the mercury concentration in air reached an undetectable level. The mercury content more clearly influenced the mercury evaporation from the admixed type amalgam specimens when the mercury content decreased below the manufacturers' recommended trituration conditions. Triturating with less mercury than the manufacturers' recommended amount cannot lower the evaporation of mercury from freshly made amalgam. Proper condensing procedures can minimize the mercury evaporation from the amalgam surface.  (+info)

Biological monitoring and exposure to mercury. (7/195)

Occupational health professionals' interest in controlling mercury (Hg) exposure, and the use of biological monitoring in this context, has been ongoing for a number of years. Evidence from urinary Hg results in a number of UK firms who have undertaken some form of biological monitoring or occupational health surveillance suggest that exposure has decreased over the last 10-15 years. This decrease precedes the establishment in the UK of an advisory biological monitoring guidance value (HGV) for urinary Hg and the production of updated medical guidance from the Health & Safety Executive on Hg exposure (MS12 1996). This latter document recommends a urinary sampling interval for urinary Hg of between 1 and 3 months, which is consistent with the reported toxicokinetics of Hg excretion, but we highlight that urinary Hg represents integrated exposure over many previous months. Mercury is a recognized nephrotoxin and MS12 1996 mentions the use of regular dipstick protein estimations. We review our experience of investigating proteinuria and enzymuria in a large-scale cross-sectional occupational study. The incidence of Hg-induced renal disease is probably very rare at current exposure levels. Therefore acceptance of a high false-positive rate of proteinuria not related to Hg exposure needs to be considered in any urinary protein testing regime of Hg workers. The establishment of an HGV for urinary Hg has raised questions about the uncertainty associated with a urinary Hg result, including factors such as diurnal variation, whether urine correction by creatinine or specific gravity is preferable and the possibility of non-occupational sources of Hg contributing significantly towards breaching the HGV. Correction of urinary Hg results by creatinine or specific gravity and the use of a fixed sampling time, such as the beginning or end of the day, substantially reduce the uncertainty in a urinary Hg measurement. But even with good laboratory precision, an individual with a true urinary Hg excretion of 20 nmol/mmol creatinine could supply urine samples of between 14 and 26 nmol/mmol creatinine. The influence of dietary sources in the UK contributing to urinary Hg values approaching or exceeding the HGV is unlikely. The use of tribal or ethnic cosmetics and remedies needs to be considered if a urinary Hg result looks inappropriately high, as some such preparations have been found to contain Hg and can be absorbed through the skin. The ability of excessive chewers or teeth grinders who have a large number of dental amalgam fillings to breach the urinary HGV in the absence of substantial occupational Hg exposure has been reported in a few Scandanavian studies. We report here a likely case of this phenomenon. Since the establishment of the HGV, our biological monitoring Hg data from a number of industry sectors using inorganic or metallic Hg have suggested that a minority of samples (13%) are still greater than the HGV.  (+info)

HLA-association in patients with intolerance to mercury and other metals in dental materials. (8/195)

A group of selected 25 patients with serious intolerance to heavy metals used for dental restoration were examined for HLA antigens. A significant increase for HLA -- B37, B47 and DR4 was found. The value of the relative risk is not significant after correction for the number of antigens tested and therefore further studies of more patients are needed.  (+info)

NaturalHealth365) Cases of chronic disease have reached epidemic proportions in the U.S., with issues related to the immune system high on the list. These diseases have all been associated with mercury-based dental amalgam fillings.. Dental amalgam fillings contain up to a 54 percent ratio of the neurotoxin mercury. The National Institute for Health, through an extensive epidemiological study, showed a high correlation between dental amalgam fillings and chronic disease. Yet, the FDA and other health agencies refuse to do anything about this huge public health risk.. The public is waking up to the dangers of dental amalgam fillings. The following are the top 10 types of chronic disease caused by the mercury in these toxic dental fillings:. 1. Autoimmune disease. Autoimmune issues linked with mercury fillings include arthritis, MS, ALS (Lou Gehrigs Disease), Parkinsons disease, Alzheimers disease, muscle tremors, joint and muscle pain, fibromyalgia, chronic fatigue syndrome, Crohns disease, ...
NaturalHealth365) Mercury, commonly used in dental amalgam fillings, is one of the most toxic substances on the planet. And, although the American Dental Association continues to insist that mercury-based silver fillings are safe, natural health experts have long warned that micro-levels of this highly-toxic substance can be released into the body, with grave health consequences.. Now, a disturbing new study shows that electromagnetic fields from WiFi - a hazard in their own right - accelerate the release of mercury from fillings, further increasing the threat to health. This research has some alarming implications - lets look at how you can protect yourself.. Amalgam fillings set the stage for a biological train wreck, according to many integrative healthcare providers. Although exposure to mercury can occur through the environment, vaccines and contaminated foods, the main source of exposure is silver dental amalgam fillings - which contain 50 percent elemental mercury. Mercury vapors, ...
According to the World Health Organization (WHO), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields. Dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population. Although it was previously believed that low levels are mercury (i.g. release of mercury from dental amalgam) is not hazardous, now numerous data indicate that even very low doses of mercury cause toxicity. There are some evidence indicating that perinatal exposure to mercury is significantly associated with an increased risk of developmental disorders such as autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD). Furthermore, mercury can decrease the levels of neurotransmitters dopamine, serotonin, noreprenephrine, and acetylcholine in the brain and cause neurological problems. On the other hand, a strong positive correlation
Q: My dentist wants to put silver amalgam fillings in my teeth. He says they are more durable than white composites. Is that correct?. A: A new research indicates that amalgam fillings do not perform as well as it was previously believed. Our friendly and very experienced dentist showed us new composite materials which bind perfectly to enamel. They look better too.. Q: My dentist claims that silver amalgam fillings are perfectly safe. Is that correct?. A: It all depends which dentist you ask that question. There are dentist who not only do not encourage patients to get these type of filings, but they would never put them in anybodies mouth. The research that we have found clearly shows that amalgam fillings pose serious hazard over time (scroll down for more evidence). Please take note that the so called silver fillings consist of 50% mercury, and mercury is poisonous - all toxicologists know this.. Q: I dont understand this. I have (mercury) silver fillings in my teeth but I do not ...
Having tooth problems? The best option when it comes to the health of your teeth is to practice good preventative care such as avoiding foods that could damage your teeth, making sure to brush your teeth regularly, and even flossing. For most people, this is more than enough to keep teeth in good shape.. However, for some people, that advice may come too late. In those cases, your teeth may be too damaged to simply ignore the problem anymore. Depending on the extent of the damage, you may need to have teeth removed or have them heavily operated on.. In other cases, you may only need some light work. On this website, I wanted to explain what a dental amalgam was. Have you ever heard of a dental amalgam? In our day and age, receiving a dental amalgam or related dental work is not as common as it used to be.. In order to help you understand what they are and to teach you when you might actually need a dental amalgam, Ive compiled information that Ive found and learned about dental amalgams. Ive ...
For many years, amalgam has been the most popular material used by dentists to fill dental cavities. This is because it is relatively inexpensive as compared to other materials, and is extremely durable. However, many in the dental profession are moving away from amalgam fillings and using other materials including porcelain and composite resin to fill cavities. In fact, some dental practices no longer offer silver amalgam fillings at all.. This trend is largely driven by consumer demand. Many individuals have decided to go with other options due to both cosmetic and safety concerns. There is no doubt that porcelain and composite resin fillings are more attractive than silver amalgam fillings because they are tooth colored and can be made to closely match the color of natural teeth. Most individuals simply do not want to have a mouth full of metal. Even if your silver amalgam fillings are in the back of your mouth, they can still show when you laugh or smile. For this reason alone, many ...
Dental amalgam-also known as silver fillings-has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. Whats more, its stable and compatible with living tissue.. But theres been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.. Mercury makes up a good portion of dental amalgams base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metals toxicity to humans, its still used in dental amalgam.. The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is ...
There has been much debate on the safety of amalgam fillings. Currently, dental amalgam is considered to be a medical device, and is regulated by the Food and Drug Administration (FDA). FDA is responsible for ensuring that dental amalgam is reasonably safe and effective, and that, among other things, the product labeling seen by dentists has adequate directions for use and includes any appropriate warnings. (source) However, an increasing number of dentists have stopped using amalgam fillings on their patients after studies have shown how mercury vapor and particulate matter derived from amalgam fillings can cause severe problems in patients. Dr. Reese is a holistic dentist and an active member of the International Academy of Oral Medicine and Toxicology (IAOMT). This organization advocates biological dentistry and achieving all the goals of modern dentistry while always choosing the safest, least toxic techniques, including safe replacement of mercury fillings.. ...
Introduction: In Vermont, cremation has increasingly become an alternative to interment of an intact body. Many of the bodies being cremated contain dental amalgams, which are commonly used by dentists to repair dental erosion and caries (cavities). They are an economical option for caries repair, and remain popular. Roughly one third of all caries fillings done in 2002 in the U.S. utilized amalgam. Amalgam is a metal alloy containing as much as 50% mercury by volume, a metal that is a known toxicant. Dental amalgams, may constitute a source of low level, continual exposure for those with these dental devices in situ and may be released to the atmosphere upon cremation. The goal of this project was to investigate: 1. The status of the scientific opinion on potential health effects that may be associated with having dental amalgams. 2. To help refine State estimates of potential mercury emissions from Vermont crematoria.
There is not one specific cause for primary fibromyalgia. Certain common features among fibromyalgia patients provide a better idea as to the primary factors that are involved in its onset, however. These include dental amalgam fillings, hormone imbalances, infection, neurotransmitter imbalances, sleep problems, problems with the thalamus gland, and physical trauma. Other factors that can play a role include chemical and food allergies and sensitivities, chronic stress, and dysfunctions in muscle metabolism. Breast implants can also contribute to fibromyalgia because the materials implants contain weaken the body`s immune system.. Dental Amalgam Fillings Dental amalgam fillings are composed of 50 percent mercury, a highly toxic compound. An abundant amount of scientific research, primarily conducted in Europe, where many countries have banned the use of mercury amalgams, proves that such fillings greatly increase the likelihood of heavy metal poisoning in the body`s glands and tissues due to how ...
Dear Department of Health,. The Chief Dental Officer Barry Cockroft declared (on ITV, see link below) that no mercury vapour is emitted from dental amalgams, or --on second thoughts-- at least not measureably. Yet this is violently at odds with the real bleedingly obvious long-established facts of the matter, as per documentation below. He further queried the point that dental amalgam is the main source of mercury exposure in humans. Again this flies in the face of the known evidence. As per documentation below.. In the context of the above, would you please tell me:. 1. On what scientific basis did Barry Cockroft assert that no measurable mercury is emitted from amgalgams?. 2. On what scientific basis did Barry Cockroft assert that dental amalgam is not the main source of mercury exposure?. 3. In the absence of such a scientific basis, why did Barry Cockroft make these very seriously misleading assertions on the major ITV Tonight program? 4. Do you appoint utter incompetents/liars/idiots to ...

This paper shows the link between dental amalgam mercury pollution and the available growing scientific research, that can no longer be ignored. We are reaching out to policy makers, NGOs and all interested parties who are working within the framework of the Minamata Convention on Mercury Treaty to urge immediate action to be taken to stop the use of dental amalgam, not by 2030, which according to a recent conference webinar in May, 2019, with the FDI (World Dental Association), is their suggested end date. In fact, FDI continued to cite old research to defend its use and to maintain the status quo. As we have referenced in our paper, another 10 years of using mercury in dental amalgam will have devasting environmental consequences for decades to come, but more importantly, the unjustifiable exposure to another decade of consumers to this known neurotoxin, is unconscionable. FDI even discussed how to address deficiencies of alternative non-mercury fillings in favor of continuing using mercury ...
The decision came as a result of the Sustainable Development Policy Institutes (SDPI) research and regressive advocacy campaigns to ban mercury dental amalgam use in the country from time to time. The research led by Dr Mehamood A Khawaja, Senior Advisor SDPI on Chemicals and Sustainable Industrial Development, over the last few years has been appreciated not only in Pakistan but also organisation working on mercury related issues in the region.. Lauding the decision of the government, SDPI termed it a right direction at a right time. SDPI is hopeful to eliminate mercury dental amalgam use not only for children and pregnant and breastfeeding women, but also public in general across the country to safeguard their health. Dr Khawja has appealed to the government to make legislation in this regard and strictly ban the use of mercury not only in dental amalgams but also in other devices. ...
For over a hundred years dental amalgam - a combination of silver, mercury, tin and other metals - has been an effective filling material for teeth damaged by decay. But it has one major drawback - its metallic appearance stands out in stark contrast to the natural color of teeth.. As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.. Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.. The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In ...

What does getting an amalgam filling involve?. Amalgam fillings are usually placed in one appointment. While the tooth is numb, your dentist will remove decay as necessary. The space will then be thoroughly cleansed and carefully prepared before the new filling is placed. If the decay was near the nerve of the tooth, a special medication will be applied for added protection. The silver filling will then be precisely placed, shaped, and polished, restoring your tooth to its original shape and function.. It is normal to experience sensitivity to hot and cold when amalgam fillings are first placed, however this will subside shortly after your tooth acclimates to the new filling.. You will be given post-care instructions at the completion of your treatment. Proper oral hygiene, good eating habits, and regular dental visits will aid in the life of your new fillings.. ...

Learn what the medical research says about the safety of mercury in dental amalgam fillings. Is it riskier to keep amalgam fillings, or replace them?
Dental amalgam consists of a combination of different metals such as liquid mercury and a powdered alloy of copper, tin, and silver. The chemical properties of mercury make it the binding agent between mercury and the alloy particles to form a nice amalgam.. Amalgam filling looks like silver and that is why it has got its name from silver filling.. Amalgam Filling Process. To treat your tooth decay with the amalgam filling, your dentist needs to first make the dental amalgam. But before that, the dentist will drill the tooth, remove the decay, and make the place for the amalgam filling.. Dentists use special kind of capsules consisting of liquid mercury and the alloy powder (containing tin, copper, and silver) for making the dental amalgam.. They have advanced tools to puncture this capsule and mix the ingredients without removing them from the capsule.. After mixing, they open the capsule taking utmost safety precautions. This is a soft filling that goes into the prepared cavity and once it ...
What is a filling? Even though most people still associate this word with pain and fear, in todays modern dentistry, geared toward patients comfort, a tooth filling is a common restorative procedure that helps repair and save teeth damaged by decay.. Dental fillings are not new. There are scientific discoveries suggesting that the oldest known dental filling may be dating to 13,000 years ago, made from a tar-like material. Another discovery of a 6,500 year old fossilized jawbone reveals that a crack on the canine tooth was stuffed with beeswax.. In the 19th century restorative dentistry starts using metals, such as gold, silver, tin, etc. that were softened to fill teeth. In 1819, a mercury based dental amalgam filling is created by the English chemist, Bell. In 1830, the mercury amalgam starts being used in the United States, and soon many harmful effects were reported. In 1859, what is today known as the American Dental Association is formed, a pro-mercury proponent.. Even though there were ...
Dentistry has evolved in many ways throughout the years. One of the biggest advancements relates to how modern dentists can repair cavities and minor tooth damage. In the past, dentists primarily used amalgam for their dental filling material. However, patients can now take advantage of a safer, more effective and natural-looking filling option using composite resin. Here are the top reasons why composite fillings can be considered superior to amalgam (or silver) fillings.. Safety: Perhaps the most well-known fact about amalgam fillings is that they contain mercury. The American Dental Association supports the use of dental amalgam as a safe, affordable and durable material. Still, the public has voiced a significant concern over the use of mercury in dental fillings. The major concern is if mercury is released from the filling resulting in adverse effects to your health. It is confirmed that amalgam fillings can, in fact, leak the toxic vapors of mercury if the margins are damaged or the ...

Dental Amalgam is a commonly used dental filling that has been used for over 150 years. It is a mixture of mercury with at least one other metal. Amalgam has many advantages over other restorative material, such as low cost, strength, durability, and bacteriostatic effects.. Dr. Zadeh, after years of using these silver fillings, no longer performs these fillings on a routine basis.. Amalgam is used in dentistry for a number of reasons. It is relatively easy to use and manipulate during placement; it remains soft for a short time so it can be packed to fill any irregular volume, and then forms a hard compound. Amalgam possesses greater longevity than other direct restorative materials, such as composite. On average, most amalgam restorations serve for 10 to 12 years, whereas resin-based composites serve for about half that time. However, with recent improvements in composite material science and a better understanding of the technique-sensitivity of placement, it should be noted that this ...
Due to its mercury content, amalgam is classified as hazardous waste by the European Waste Catalogue, and the Hazardous Waste Directive (91/689/EEC) states that all waste amalgam produced by dental practices must be disposed of safely without posing any risk to human health or the environment. It is therefore essential that all dental practices have an adequate amalgam separator on the premises to ensure full compliance with legislation..

Could your dental work be exposing you to toxins?. Dentists have been using dental amalgam for more than 150 years, its that silver-colored filling used for cavities, but what some people dont know is that 50-percent of that metal mixture is made of mercury. I was trying to avoid mercury when I was pregnant and nursing. I knew all the fish not to eat, but I had no idea it could be in my mouth, dental patient Amy Forseter said.. The 38-year-old says shes had more than a dozen cavities; most of them filled with dental amalgam, a mixture of metals thats 50-percent liquid mercury, a naturally occurring element thats highly toxic.. As soon as I learned that I had these toxins in my mouth, I wanted to immediately get it removed, she said.. For years some scientists have said the mercury from these fillings can leak, seeping into the body causing neurological problems for some people.. If youre a healthy person who can detox this, there may not be any noticeable changes, but for those of us ...
Mercury from dental amalgam. This pollutant is omnipresent in the United States. Amalgam fillings are placed indiscriminately into cavities, because amalgam is cheap and easy to work with. The American Dental Association insists that dental amalgam is safe[5], while the Occupational Safety Health Administration (OSHA) and Environmental Protection Agency (EPA) classify amalgam as a toxic and hazardous substance: Another source of exposure to low levels of elemental mercury in the general population is elemental mercury released in the mouth from dental amalgam fillings[6] (Transportation, storage, and disposal of mercury is regulated by the Code of Federal Regulations, 29 CFR 1910.1000, and its willful violation is a criminal offense, except when mercury is stored in your mouth by a licensed dentist.) It isnt surprising that dentists in the United States have the highest rate of depression, suicide, and drug and alcohol addiction, and the lowest life expectancy among all medical ...
A childs first exposure to mercury from amalgam fillings* can occur at the moment of conception. Think of that and the implications it holds! At first glance it may sound like a crazy idea and easy to dismiss but it is absolutely true and cannot be discarded. If the mother has mercury amalgam silver fillings in her teeth the fetus will not only be exposed to mercury released from her fillings at the moment of its conception, but throughout the entire gestation period. It is being exposed to elemental mercury from dental fillings before it even has a tooth! However, the bad news doesnt end there. If a mother has amalgam fillings while she nurses her baby it will also be exposed to mercury released from her fillings-for as long as the child is being nursed. In addition, most babies in modernized countries will receive 10 vaccinations by age 5. These 10 vaccinations will consist of 33 doses of the vaccines, beginning shortly after birth and continuing through early childhood. Each dose will ...
However, according to an article written back in 2013 by the then ADEA President, Dr. Valachovicin, at the New York University College of Dentistry, less than 20% of the restorations placed in their dental clinic are amalgam, and this figure was declining. Apparently this trend results largely from patient preferences and the belief that it is unethical to force amalgam on patients who dont want it. I believe that in 2017, the vast majority of dental offices in Canada will use very little amalgam and some dental manufacturers have already ceased production of dental amalgam, e.g. Coltene. Thus, despite being a good restorative material, dental amalgam may just fade away and die an esthetic death. Consequently, we must focus our efforts on teaching how to use the restorative materials that the public wants. We also need to deal with all the amalgam restorations that ...

White fillings have always been considered less long lasting than silver amalgam fillings. But there are now new materials available with properties comparable to silver amalgam, and these are proving to be very successful. The life expectancy of a white filling can depend greatly on where it is in your mouth and how heavily your teeth come together when you bite. Your dentist can advise you on the life expectancy of your fillings. However, any fillings provided on the NHS are automatically guaranteed for one year.. ...
Safety and Appearance: Amalgam fillings may be a poor choice for people with metal sensitivities. Some have described a metal taste in the mouth from amalgam fillings. On a more cautious note, it has been thought that people with amalgam fillings are at a risk of mercury toxicity. However, no studies have proven there are hazards of having mercury as a component of amalgam dental fillings. Composite fillings do not contain metals that may cause sensitivity or toxicity, and have a further benefit of offering a more attractive and natural tooth-like appearance.. Durability: Amalgam fillings tend to be more durable than composites. However, recent advances in dental research and technology have resulted in improvements in the strength of composite resin materials, such that composite fillings may used for all teeth including molars. In addition, composites are less likely to have the potential disadvantage of weakening the affected tooth, compared to amalgam fillings.. Tooth Shaping: Composite ...

In response to that study, researchers from a university dental department published a study entitled: No evidence of renal toxicity from amalgam fillings. [4] I consistently observe that research suggesting amalgam toxicity is usually countered by follow-up research from some dental department. This follow-up study examined only 10 subjects without any controls. Kidney function was examined only within a very narrow time frame, before and then two months after amalgam removal. No difference in kidney function was found over that time. But mercury can take many months to be cleared from the body and the kidney measures could have remained constant over that time due to persistent kidney impairment. Why did they choose such a narrow range of observation in so few patients? Why didnt they measure kidney function 6, 12, and 24 months after amalgam removal to get a better picture? Why didnt they compare their small group of subjects to controls? ...
/PRNewswire/ -- Research published this week in the peer-reviewed Journal of Occupational Medicine and Toxicology (JOMT) shows that the safety thresholds for...
The new research shows that electromagnetic frequencies (EMFs) - which are produced by wireless technologies such as cell phones, laptops, tablets and microwave ovens - can accelerate and intensify the release of mercury. The study also suggests that routine medical procedures, such as magnetic resonance imaging (MRIs) and X-rays, are other culprits in quickening mercury release. To conduct the study, researchers placed 20 extracted, mercury-filled human teeth in artificial saliva and exposed ten of them to 20 minutes of radiofrequency radiation from a standard laptop computer operating at 2.4 GHz. Researchers then measured the mercury levels in the artificial saliva surrounding the teeth. They found that levels in the fluid of the unexposed teeth were .026 milligrams per liter, as compared to .056 for the mercury-filled teeth - reflecting a doubling of the mercury release.. The research, which was published in 2016 in Journal of Environmental Health Science and Engineering, was the first study ...
Mercury. The problem with dental amalgam fillings is that the amalgam is a liquid, albeit a very stiff one. This means that as the fillings erode, mercury is released into the mouth where it is inhaled and deposited in bone, kidneys and the brain. There is some very good evidence which now links mercury from dental amalgams to Alzheimers disease, but it may well be that it has the potential to trigger MS because heavy metals act as immune adjuvants (this is, of course, the reason why mercury as thimerosal is used in vaccinations). My personal view is that nobody should be walking around with dental amalgam in their teeth, but we can measure to see if this is a problem - firstly by doing a Kelmer test which measures urinary mercury levels before and after a chelating agent and secondly doing mercury sensitivity tests to see to what extent the immune system is activated by the presence of mercury. If these tests were very abnormal then there would be a clear indication for going ahead and getting ...

Conclusions Recently I reported on the methodology and machinations involved in vaccine-related injury cover-ups by the elitists in science and government at the Simpsonwood Conference on Thimerosal in vaccines. A new scandal has been recently released concerning the safety of mercury contained in dental amalgam, which is of equal magnitude and again showing the modus operandi of the government/elitist scientists coalition. The official name of the report is: Dental Amalgam: A Scientific Review and Recommended Public Health Service Strategy for Research, Education and Regulation. This report is described as the Trans-agency Working Group on the Health Effects of Dental Amalgam, which included representatives of the National Institutes of Health, the Center for Devices and Radiological Health of the U. S. Food and Drug Administration, the Centers for Disease Control and Prevention and the Office of the Chief Dental Officer of the Public Health Service. These organizations requested that the Life ...
Mercury-free Dentistry As a member of the International Academy of Oral Medicine and Toxicology, your dentist at Dental Solutions endorses mercury-free dentistry. Many patients have received dental amalgam fillings, a metal filling that contains a significant amount of mercury, which can be hazardous to health. Here at Dental Solutions, we are trained to safely remove amalgam fillings without exposing the patient to mercury emissions.
Mercury - a neurotoxic heavy metal - is so dangerous that the World Health Organization says there is no safe level for exposure.
Dental amalgam is the most thoroughly researched and tested dental material of all those in use today. Although it contains trace amounts of mercury (a known toxin), when this element is bound to other components of amalgam, it becomes safe for use. In 2006, government-funded studies further concluded that there is no evidence that dental amalgam causes brain injury or neurological problems in children. Similar supportive statements have been released by the Federal Drug Administration (FDA), National Institutes of Health (NIH), U.S. Public Health Service (USPHS), Centers for Disease Control (CDC) and World Health Organization (WHO), as well as the Alzheimers, Pediatric, Autism and Multiple Sclerosis Associations.. In fact, over 950 scientific and medical studies support amalgams unbeatable strength, safety and cost-effectiveness. The ADA Research Foundation also notes that it is the strongest and most durable direct restoration for large load-bearing restoration on posterior ...
Amalgam fillings are usually placed in one appointment. While the tooth is numb, your dentist will remove decay as necessary. The space will then be thoroughly cleansed and carefully prepared before the new filling is placed. If the decay was near the nerve of the tooth, a special medication will be applied for added protection. The silver filling will then be precisely placed, shaped, and polished, restoring your tooth to its original shape and function.. It is normal to experience sensitivity to hot and cold when amalgam fillings are first placed, however this will subside shortly after your tooth acclimates to the new filling.. You will be given post-care instructions at the completion of your treatment. Proper oral hygiene, good eating habits, and regular dental visits will aid in the life of your new fillings.. ...

  • This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be used. (
  • Thus, amalgam (an alloy of mercury with another metal or metals, from the French word amalgame) was invented. (
  • Dental amalgam is a mixture of materials containing powdered alloy, metals and mercury. (
  • Also, when using an amalgam alloy for a filling, not as much natural tooth structure has to be removed in order to place the filling. (

  • In reality, there are a plethora of studies that have documented how a person's existing dental restorations can be affected by the peroxide-based whiteners used to bleach teeth. (
  • As evidence in support of this opinion, the simple fact that peroxide-based whiteners have been used extensively over the last 30 years by the general population, and no wide-spread clinical issues have yet been observed with composite fillings, and teeth bleaching continues to be promoted by the dental community as a whole, seems to be a confirmation of this point. (
