There is widespread concern regarding the safety of silver-mercury amalgam dental restorations, yet little evidence to support their harm or safety. We examined whether mercury dental amalgams are adversely associated with cognitive functioning in a cross-sectional sample of healthy working adults. We studied 550 adults, 30-49 years of age, who were not occupationally exposed to mercury. Partic...

This report is a critical evaluation of the use of dental amalgam with special consideration of the possibility of chronic mercury poisoning. The description of psychic and somatic symptoms associated with corrosion of amalgam might help people with similar symptoms to recognize the possible source of their problems. Medical practitioners need to recognize the characteristic manifestations of m...

Seven multiple sclerosis subjects had their silver dental fillings (amalgams) removed which contained approximately 50% mercury. A visual evoked response (VER) test was performed before amalgam removal. Approximately six months after amalgam removal a second VER test was performed on all subjects, and the latencies of the VER decreased significantly. The mean latency of P1 for the right and lef...

Today's environment has different impacts on our body than previous generations. Heavy metals are a growing concern in medicine. Doctors and individuals request the removal of their amalgam (silver mercury) restorations due to the high mercury content. A safe protocol to replace the silver mercury filling will ensure that there is minimal if any absorption of materials while being removed. Stro...

Mercury, as any other heavy metal, may cause environmental damages due to its accumulation and biotransformation. Dental offices, whether private or institutional, use dental amalgam as a restorative material on a daily basis. Dental amalgam is composed of mercury (50%), silver (30%) and other metals. Approximately 30% of the amalgam prepared in dental offices (0.6 g per capsule) are wasted and...

BACKGROUND Patients with certain autoimmune and allergic diseases, such as systemic lupus, multiple sclerosis, autoimmune thyroiditis or atopic eczema, often show increased lymphocyte stimulation by low doses of inorganic mercury in vitro. The patients often report clinical metal hypersensitivity, especially to nickel. OBJECTIVE AND METHODS In this study we examined the health impact of amalg...

Amalgam has, ever since its introduction 150 years ago, been the subject of recurrent controversies because of its mercury content. Amalgam is an unstable alloy and continuously gives off mercury (Hg) in the form of gas, ions and abraded particles (Stock, 1939 a, Radics et al., 1970, Mocke, 1971, Till and Wagner, 1973, Svare et al., 1981). Amalgam contains an especially cor-rodible gamma-2-phas...

3 ilver-mercury fillings—also called dental or mercury amalgams— ave been used in dentistry since 1832. In 1840, the dental ssociation of the day argued over whether to use mercury as filling material because it was cheap, or to withdraw it ecause it was toxic. The safety debate had already begun and ould be called “Amalgam War I.” In the late 1920s, Dr Alfred tock, a biochemist and researcher,...

1 THE TOXIC EFFECTS OF THE MERCURY IN DENTAL AMALGAM FILLINGS ON THE ENVIRONMENT AND HUMAN HEALTH A FACT SHEET PREPARED BY The International Academy of Oral Medicine and Toxicology www.iaomt.org “For medical reasons, amalgam should be eliminated in dental care as soon as possible. As a result, one of our largest sources of mercury in the environment can be eliminated.’’ 1 --Dr. Maths Berlin, th...
