A brief note on nothing. A couple of decades ago there was a scare relating to the mercury in silver fillings as a cause of Multiple Sclerosis. That slowly expanded to any neurological disease.

I haven't heard much of the story lately. That may be because all of the money that can be made by removing silver alloy restorations has been made. And the results?

There has been no decrease in the incidence of multiple sclerosis in the United States. Over two decades should be enough time for the affects of new, plastic composite restorations to be seen. There is no change.

To quote from the National Multiple Sclerosis Society in the US:

"There is no evidence that heavy metal exposure causes M.S."

It's repeated so often that it has long been regarded as a cliche, but we live in an increasingly information-intensive world, bombarded by facts and figures from an endless queue of media outlets, websites, television shows and Windsor-based science bloggers. This abundance of information often comes with a cost. If my grandfather wanted to learn something about his health - and of course like many men of his generation he didn't - he would have seen a doctor or read a reputable book. These days, we receive much of our information on the fly in bite-sized chunks from websites and media articles. Fast food culture applied to research.

The result is like trying to build an igloo by catching snowflakes. We snatch little snippets of information here and there, but often they lack any real substance, failing to really contribute to the building of a complete understanding of a subject. Stripped of context or reference, in the end these factlets are as intangible as the ether they travel through.
