Having more than eight fillings may raise levels of blood mercury
are made of a mixture of metals include silver and tin
Now for the first time scientists have found a link between dental fillings and mercury exposure – .. which can lead to serious diseases
in Britain more than a million children under five years and has at least two fillings
British have a reputation of teeth in poor condition with average adult has seven fillings -. compared to three in the US .
researcher Dr. Lei Yin, University of Georgia, said. “Tooth decay is one of the most prevalent chronic diseases
“I think most people have experienced dental fillings, but the type of material used the dentist is not something that is much discussed.”
Tooth decay is one of the most prevalent chronic diseases
Dr. Yin and colleagues analyzed data from nearly 15,000 people to identify a link between dental fillings and mercury poisoning potential for the first time.
Fillers are put together using mercury, silver, tin and copper to form a liquid called dental amalgams then hardens.
Mercury represents about 50 percent of the compound and is used to bind metals and provide a strong, tough and durable.
However, contributes significantly prolonged levels of mercury in the body, according to findings published in Ecotoxicology and Environmental Safety way.
levels of mercury in blood lifted may increase the risk of brain, heart and kidney disease
exposure to mercury in dental fillings is not a new concern, but previous studies were inconsistent and limited, researchers say.
Professor John Yu, said: “This study is trying to provide the most accurate levels of exposure that will form the scientific basis for future risk assessment.”
he said the study was the first to also controlling for age, education, ethnicity, race, sex, smoking and consumption of seafood -. a taxpayer knows that mercury levels in the body
a more detailed exposure to specific forms analysis found a significant increase in methylmercury increase – the most toxic form – related to dental fillings
professor Yu said this suggests that the human gut bacteria living in the intestines can transform different types
dental amalgam has .. has been the material form of go-to dental filling more than 150 years because it is affordable and durable.
However, heavy metal is known to be toxic at high levels causing brain, heart, kidneys, lungs and immune system damage.
recent research suggests methyl mercury can cause damage even at low levels
Professor Yu said:.. “As toxicologists know that mercury is poisonous, but it all depends on the dose so if you have a dental filling maybe it’s OK.
“But if you have more than eight dental filings the potential risk of adverse effects is greater.”
fillers are composed of mercury, silver, tin and copper forming a liquid called amalgam dental
people numerous dental fillings that are also exposed to mercury from other sources – such as environments seafood or work – are at greater risk
individuals with more than eight fillings had about 150 percent more mercury their blood than those who have none
according to its website Administration Food and Drug US dental amalgams considered safe for adults
But it says :. “Pregnant women and parents with children under six who are concerned about the absence of clinical data, long-term health outcomes should talk to your dentist.”
Mercury represents about 50 percent of the compound and is used to join metals
the study also examined composite resins dental -. a free alternative to mercury fillings which can release small amounts of bisphenol A (BPA)
found no evidence of hormone disrupting chemicals in urine samples, but researchers said more studies are needed
Dr. Yin said :. “It is important that physicians and patients to be informed of their choices.
” Now we have an excellent starting point for assessing the potential risk of dental materials on human health. “
