Raspberries, Piercings & Smoking – Oh, My!

So back to blogging, following up on a few older posts with more recent items I ran across during the hiatus…

Nontoxic Oral Cancer Treatments

We’ve looked at causes and early detection of oral cancer, but then what? Well, if a pair of recent studies holds up, we just might wind up treating precancerous lesions with raspberries.

“Part of the biggest clinical challenge,” says Dr. Susan Mallery in DrBicuspid’s report on her work, “is that we cannot currently identify which lesions will progress to oral cancer. Having nontoxic and effective treatment options available would be a great benefit to both patients and healthcare practitioners.”

In a 2010 study in Pharmaceutical Research, Dr. Mallery’s team found that applying a black raspberry gel directly to the lesions kept precancerous cells from becoming cancerous.

Based on the known mechanisms by which berry compounds function at the cellular levels, researchers speculate that the promising gel trial results reflect activation of two related pathways – apoptosis and terminal differentiation – in the premalignant cells. The ultimate benefit is that damaged cells don’t continue to divide and are therefore not retained.

A new study by the team, published in Molecular Pharmaceutics, showed similar efficacy of patch-delivered fenretinide, a synthetic vitamin A compound. The authors suggest that these “chemopreventives” could be used alone or in rotation, though the raspberry gel was enough for many.

“We’re getting a pretty good handle on what enzymes you need and how you metabolize the compounds, which will give a predictive indicator if you’re going to be a good responder to the raspberry gel alone,” Dr. Mallery said.

How Body Piercing Can Go Wrong

A while back, we looked at a few of the problems oral piercings can cause for your teeth and gums – from infection to pushing teeth out of alignment. But there are others.

Last month, the American Journal of Clinical Dermatology published a comprehensive review of “the medical consequences of body piercing.” First, there are those that can crop up regardless of where the piercing is.

Localized infections are common. Systemic infections such as viral hepatitis and toxic shock syndrome and distant infections such as endocarditis and brain abscesses have been reported. Other general complications include allergic contact dermatitis (e.g. from nickel or latex), bleeding, scarring and keloid formation, nerve damage, and interference with medical procedures such as intubation and blood/organ donation.

Then there are “site-specific” problems. Of concern to dentists:

Oral piercings may lead to difficulty speaking and eating, excessive salivation, and dental problems. Oral and nasal piercings may be aspirated or become embedded, requiring surgical removal.

What the report doesn’t go into, though, are concerns of biological, holistic or integrative practitioners over punching through acupuncture points and housing metal in the body. These can block and disturb energy along the meridians, which can damage health over time. You can learn more about the issue in this helpful overview.

Smokers Avoid the Dentist

Not long after we looked at why smokers need to kick their habit before getting treatment for gum disease – a disease that affects tobacco-users disproportionately – the CDC released some new and sad data on smokers, dental problems and dental care.

The CDC looked at 2008 survey responses from more than 16,000 adults ages 18 through 64.

More than a third of smokers reported having three or more dental problems, ranging from stained teeth to jaw pain, toothaches or infected gums. That was more than twice as much as people who never smoked.

But 20 percent of the smokers said they had not been to a dentist in at least five years. Only 10 percent of non-smokers and former smokers had stayed away that long, the study found.

Smokers seem to be aware their dental health is worse “but they’re not doing anything about it,” said Robin Cohen, a CDC statistician who co-authored the new report.

Why not?

Half said they couldn’t afford it, which makes sense: Smoking rates are higher among lower income groups, it’s an expensive habit and the amount and type of damage it causes can quickly inflate a dental bill. I suspect fear plays a role, too – fear of The Lecture, as noted before, and fear of finding out just how bad the problems are.

Unfortunately, the avoidance tactic usually ends up costing much more. According to a study in the Journal of Periodontology, patients with gum disease who did without periodontal treatment could only replace 4 teeth before they were spending more than they would have for a lifetime of periodontal care.

A lifetime!

“Feasible”?

Last, a headline – from a story about recent UK debates on the use of mercury amalgam in dentistry:

Well, amalgam fillings are sure as heck not feasible in any term!
