The WHO report from 1991. It is over 5 years since the meeting that this WHO-report is grounded on was held, but it still is a good source of knowledge in this field.
The "Handbook on the Toxicology of Metals" (Friberg 1986) is, in my eyes, a good handbook in metal-toxicology. Even though it is about 10 years old it outlines the toxicological principles / symptoms / and methodologically problems in a nice form. However, figures are some-times not up-to-date when seen in light of more recent science in the field.
"it is inappropriate at this time to recommend any restrictions on the use of dental amalgam"
This statement is based on lack of evidence for risk rather than evidence of safety as can be seen from the following statement:
"health risks cannot be totally ruled out because of the paucity of definite human studies... additional research is needed to resolve the question of whether the mercury in dental amalgam poses any significant health risk to patients"
"Available data do not justify discontinuing the use of any currently available dental restorative materials or recommending their replacement"
This statement is based on lack of evidence for risk rather than evidence of safety as can be seen from this statement:
"Lack of reliable quantitative estimates of the risks and benefits of the various dental materials discussed at this conference precludes calculation of benefit/risk ratios. The paucity of data concerning predictable risks associated with restorative dental materials was striking... While the current evidence supports the concept that existing dental restorative materials are safe, it must be recognized that the supporting data are incomplete"
"Available data do not justify discontinuing the use of silver-containing dental amalgam fillings or recommending their replacement"
"Although human experimental evidence is incomplete at the present time, the recent medical research findings presented herein strongly contradict the unsubstained opinions pronounced by various dental associations and related trade organisations, who offer assurances of amalgam safety to dental personnel and their patients without providing hard data"
"The potential risk from amalgam mercury can hardly be compared to other risks such as lead from car exhaust gases or mercury from fish. There are substantial differences as regards continuity and levels of exposure and chances to avoid the exposure... The dental profession has been reluctant to publish the whole truth about Hg exposure from DA and to initiate corrective measures. This reluctance is possibly due to the symbiosis existing between dental scientific organisations and the dental industry... It might not be possible to reach a complete scientific proof of Hg poisoning by DA. However, in science this is not a new situation"
"The extensive published knowledge about mercury toxicology indicates that toxic effects from amalgam mercury can not be excluded... A comprehensive bibliography with over 8000 titles on mercury and its health effects can be obtained from the authors."
