Dental Amalgam Mercury Poisoning: Why Is It Still an Issue?

This is a guest post written by Harmon Pearson who is currently pursing a post graduate degree in dental science. He  spends time blogging about his pursuits and writing on dental care. When he is not studying, he enjoys restoring antique pendulum timepieces. How is it that in the 21st century we continue to put a known toxic element—mercury—into our mouths?  The question may seem straightforward, but the answer, curiously, is not.  Mercury remains a primary ingredient in dental amalgam, also known as silver fillings.  Other ingredients include copper, silver, tin, and zinc.  These elements when bound with mercury form what’s typically referred to as a stable compound.  It’s hard and resilient to degradation in the mouth environment making it a seemingly ideal compound for replacing small amounts of decayed or removed tooth material.  Because of this, it’s remained a … Read more

Should There Be a Direct-to-Consumer Pharmaceutical Advertising Ban

An interesting article is written by Lia Mulligan titled “You Can’t Say That on Television: Constitutional Analysis of a Direct-to-Consumer Pharmaceutical Advertising Ban,” which appeared in the 2011 issue of the American Journal of Law and Medicine (vol. 37, pages 444-467).

Darvon and Darvocet banned in U.S.

I find it interesting to hear that the drug commonly known as Darvocet and also similarly Darvon has been banned in the U.S. as of November 19, 2010. The formal name of the drug is Dextropropoxyphene and is in the opiod category of drugs. If you know someone who wants to help a drug addicted friend or loved one, refer them to this website so they can see what they can do to help. This ban came by the FDA in response to research that suggests the drug Darvocet can lead to heart problems such as heart arrythmias. The drug is also known to be addictive and is associated with some deaths. It is commonly prescribed in the treatment of pain. I personally was prescribed darovcet in 2008 in an attempt to treat my chronic 24/7 headache caused by the … Read more
