First they measured the intra-oral levels of mercury generated using a standardized technique.

Then they used a computer simulation to determine what body burden they would likely produce.

The Calgary Medical School felt that further human experimentation might unnecessarily expose experimental subjects to excessive levels of mercury so our work turned to animals. The sheep is the most common obstetric mammal. The first experiment with sheep was a distribution tracer study that found out where the mercury spread to once released from the fillings.

The next experiment looked at spread of mercury from installed amalgam fillings into a fetus since the fetus is the most vulnerable to harm from heavy metal exposure during development.

Dr. Summers contacted the research team in Calgary and asked to participate in the next project. She found that installing amalgam fillings in wild caught monkeys caused antibiotic resistant organisms to develop in the intestinal flora within two weeks.

Measurements of sheep kidney function found a 60% drop in inulin clearance. This is a clear sign that amalgams impacted kidney function in the sheep.

Dr. Haley’s team found they could reproduce all of the 7 histological hallmark signs of Alzheimer’s Disease only by using inhaled elemental mercury vapor. This is the form that comes off amalgam.

The German Department of Health had banned amalgam use in women and children following the International Academy of Oral Medicine and Toxicology in Düsseldorf in 1992. Members of the dental profession protested that they hadn’t been given an opportunity to present their evidence of safety. This conference consisted of 25 presenters and 2 moderators who are experts in mercury. The peer reviewed conclusions supported the German ban on exposure of children and women of childbearing age to mercury from amalgam.

The video from this research shows that the introduction of 100 times less mercury than found in the cerebral spinal fluid of amalgam bearers into a cell culture of growing nerve cells immediately halts growth and produces neurofibrillar tangles similar to those seen in Alzheimer’s Disease.
WHO Environmental Health Criteria 118: Inorganic Mercury. World Health Organization, Geneva, 1991
The WHO has determined that dental amalgam is the predominant source of human exposure to mercury.
human daily dose of mercury from various sources is:
Dental amalgam = 3.0-17.0µg/day (Hg vapor)
Fish and Seafood = 2.3 µg/day (methylmercury)
Other food = 0.3 µg/day(inorganic Hg)
Air & Water = Negligible traces
“A specific no-observed–effect level (NOEL) cannot be established”
In 1991 Dr. Murray Vimy (firstname.lastname@example.org) our founder participated in the WHO assessment of the daily dose received from amalgam in Genoa, Italy. The conclusions of this expert ad hoc committee are now in the Criteria document 118. Email: Murray Vimy (email@example.com)
