pfizer sildenafil viagra jurong raided People with more than eight dental fillings may have 150 per cent more mercury in their blood, increasing the risk of brain, heart and kidney damage, a new study has found.
see url Dental surface restorationsor, commonly known as dental fillings, is composed of dental amalgam – a mixture of mercury, silver, tin and other metals. The research by University of Georgia in the US, analysed data from nearly 15,000 individuals and is the first to demonstrate a relationship between dental fillings and mercury exposure.
here “Tooth decay is one of the most prevalent chronic diseases. I think a majority of people have experienced dental fillings, but the kind of materials the dentist uses is not something that is really discussed,” said lead author Lei Yin, a scientist at University of Georgia.

It was the first study to control for age, education, ethnicity, race, gender, smoking and seafood consumption, which also contributes to mercury levels in the body, he said.

follow Yu said this result suggests the human gut microbiota, a collection of microorganisms living in the intestines, may transform different types of mercury.

However, about half of the compound contains mercury, a heavy metal known to be toxic at high levels, causing brain, heart, kidney, lung and immune system damage.

If you have one dental filling, maybe it is ok. But if you have more than eight dental filings, the potential risk for adverse effect is higher,” Yu said.

The results show that individuals with more than eight fillings had about 150 per cent more mercury in their blood than those with none. The study also looked at dental composite resins, a mercury-free alternative for dental fillings that can release small amounts of bisphenol A which may cause developmental or reproductive damage.
