Mercury from dental fillings exceeds Reference Exposure Level: Report

A new risk assessment report submitted by the International Academy of Oral Medicine and Toxicology this month to the U.S. Food and Drug Administration (FDA) warns that mercury from dental fillings is estimated to cause 67.2 million Americans to exceed the Reference Exposure Level (REL) of 0.3 ug/m3 established by the U.S. Environmental Protection Agency (U.S. EPA) in 1995.

Review: Mercury likely plays role in development of AD

Mercury likely plays a role in the development of Alzheimer's disease, according to a review of relevant scientific literature published this month in The Journal of Alzheimer's Disease. Dr. Joachim Mutter of Germany, Dr. Richard Deth of the United States, and other esteemed researchers collaborated on the groundbreaking article Does Inorganic Mercury Play a Role in Alzheimer's Disease? A Systematic Review and an Integrated Molecular Mechanism, which clarifies the need for continuing research to understand the cause of neurological diseases such as Alzheimer's.

Global 'phase down' of dental mercury use finds support

Hailed as "a breakthrough" by Green Groups, an agreement in concept was reached yesterday by a World Health Organization (W.H.O.)-convened international expert group, supporting the "phase down" of dental mercury use worldwide. However, the groups note that there is still much work to be done in deciding how and when a global dental amalgam phase down will occur.

Dental fillings without gaps

Tooth cavities are usually closed with plastic fillings. However, the initially soft plastic shrinks as it hardens. The tension can cause gaps to appear between the tooth and the filling, encouraging more caries to form. For the first time, researchers have simulated this process.
