Linking Zinc Poisoning to Denture Cream continued...

"The American Academy of Neurology considers any violation of these ethics policies to be egregious misconduct," the organization says in a statement provided to WebMD.

Shay says he was critical of the Nations report because he felt the researchers' method of measuring zinc in dental cream had "fundamental flaws." After the Nations team refused to accept his revisions, he says, he sent the manuscript to P&G.

"To fact-check my revisions, I shared it with a colleague at P&G," Shay tells WebMD. "I said, 'Don't share this around, but I'm interested in if the following facts are true or not. ... There was no sense of 'Squash this,' or anything. It was entirely my way of trying to make sure my review was accurate."

The ABC report implied that Shay managed to delay publication of the Nations report by about two years. In fact, it appeared some 15 months after it was submitted, "in line with standard time frames," according to the American Academy of Neurology.

And regardless of how the Nations team measured zinc, Shay -- a geriatric dentist at the Ann Arbor VA who has studied dental-cream use -- admits that many patients with poorly fitting dentures use wildly excessive amounts of denture cream to make them fit.

The irony, he says, is that the cost of using dental cream in this way quickly exceeds the cost of new, better-fitting dentures.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
