More than eight dental fillings can up mercury levels in blood

If you have one dental filling, maybe it's OK. But if you have more than eight dental fillings, the potential risk for adverse effect is higher

September 28, 2016: Tooth decay is one of the most prevalent chronic diseases worldwide. Dental amalgam — the fillings used for surface restorations consisting of a mixture of mercury, silver, tin and other metals — may significantly increase mercury levels in the body, a study has found.

Dental amalgam has been the go-to dental filling material for more than 150 years, because it is affordable and durable.

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, the researchers said.

“If you have one dental filling, maybe it’s OK. But if you have more than eight dental fillings, the potential risk for adverse effect is higher,” said Xiaozhong “John” Yu, Assistant Professor at the University of Georgia.

Individuals with more than eight fillings had about 150 per cent more mercury in their blood than those with none.

Yu said this result suggests the human gut microbiota — a collection of micro-organisms living in the intestines — may transform different forms of mercury.

Further, the study found that a significant increase in methyl mercury, the most toxic form of mercury, is also related to dental fillings.

This methyl mercury may cause damage even at low levels, the researchers warned.

In addition, the researchers also looked at dental composite resins, a mercury-free alternative for dental fillings that can release small amounts of bisphenol A, or BPA, which may cause developmental or reproductive damage.

The research, which analysed data from nearly 15,000 individuals, was the first to control for age, education, ethnicity, race, gender, smoking and seafood consumption — a known contributor to mercury levels in the body.

The results were published online in the journal Ecotoxicology and Environmental Safety. (IANS)

The 2020 Summer Olympics in Tokyo will be postponed until next year because of the coronavirus pandemic, Japanese Prime Minister Shinzo Abe announced Tuesday.

Although the International Olympic Committee had said it would spend up to a month debating the matter, the decision to postpone became inevitable after several countries said they would not send athletes if the Games were held this summer.

“The IOC president and the prime minister of Japan have concluded that the Games must be rescheduled to a date beyond 2020, but not later that summer 2021 to safeguard the health of the athletes, everybody involved in the Olympic Games, and the international community,” the IOC and the Japanese organizing committee said in a joint statement Tuesday.

Both committees say they made their decision after consulting with the World Health Organization. Abe and the IOC had said that canceling the Games had always been out of the question.

“The Olympic Games in Tokyo could stand as a beacon of hope to the world during these troubled times that the Olympic flame could become the light at the end of the tunnel in which the world finds itself at present,” the IOC said.

Abe told reporters in Tokyo that when the Games finally gets under way, it will prove that “humanity had beat the coronavirus.”

The Summer Games were to have opened July 24.

Team USA, which represents triathlon and duathlon Olympic contenders, tweeted its thanks to the Tokyo organizers for what it says is “all you have done for a great Olympic and Paralympic Games. We wish you all the best as you keep your communities safe and offer our cooperation and support as you prepare to host the world.”

The Olympics have been canceled three times since the modern Games began in 1896. They were scrapped in 1916 during World War I and in 1940 and 1944 during World War II.

The Games have been boycotted, propagandized by Nazi Germany, and attacked by terrorists, but have never before been postponed.

Japanese organizers said Tuesday they are also postponing the Olympic torch relay that was supposed to start Thursday.

The flame arrived in Japan from its traditional lighting in Greece on March 12. It was supposed to have traveled around Japan, to be used to light the flame at the opening ceremonies in Tokyo.
