Dear Trevor:
It is my understanding that, at least in the past, palladium alloys were
fairly commonly used in dental fillings. I don't know whether contemporary
amalgam formulations include this metal or not. The review of palladium
toxicity in Seiler, Sigel & Sigel's Handbook on Toxicity of Inorganic
Compounds (1988; Marcel Dekker) notes: "There is little evidence of hazards
to workers handling [palladium] metal." The review goes on to state that
"Palladium compounds do not pose a serious allergy problem similar to that
associated with certain platinum salts."
You may recall that several years ago, a media-fed panic over health effects
of mercury-containing dental fillings prompted many folks to have their
fillings replaced. This was certainly a boon to dentists, and savory fare
for the product liability attorneys, but there has never been any compelling
evidence that mercury-containing dental fillings pose a threat to health.
Kind regards,
Roger
