As part of the check-up, your dentist probably screens you for oral cancer. Right? I know mine does. But apparently, some dentists aren't performing these checks as thoroughly as they should. It's not their fault, though, according to the article -- they're not given proper training, and don't really know what to look for. But seeing as dentists spend about a gazillion years in school, I'd like to think that cancer screening is on the curriculum. It is, after all, a matter of life and death. They also aren't too clear on the top risk factors for oral cancer -- smoking and alcohol. Come on, even I know those.

What do you think? Do you trust your dentist when it comes to oral cancer, or has the article scared you?

I never would have predicted it -- that a tooth could become a tool for dispensing medication. But the refinement of such a creation is actually in the works and before long, you may be asking not for a gold or decorative tooth but for one capable of doling out your drugs in the exact doses and at the right times.

Think about this:

Researchers from Europe and Israel are working right now on a tiny dispensing system called IntelliDrug. Their goal is to create parts small enough they can fit into a false tooth placed in the back of the mouth. The device will release a specific amount of medication at certain intervals so patients receive the proper dosage right on schedule.

This invention, crafted by an Israeli dentist, could pick up the slack for people who forget to take medicine and could save lives for those whose lives depend on scheduled drug therapy. It could also allow for better absorption of medication into the body.

The IntelliDrug device will deliver medicine directly into the bloodstream through the lining of the cheek around the mouth. Saliva, meanwhile, mixes with the drug and carries it throughout they body in a manner more efficient than just swallowing a pill every few hours.

While researchers hope to one day turn their device into a replacement tooth, the apparatus -- consisting of a stainless steel housing, a pump, custom valves, a microprocessor, batteries, and a reservoir for the drug pill -- currently comes in the form of a block the size of two teeth. It is strapped to the the side of teeth and hugs the inside of the cheek. The unit can be removed, and a technician can refill the drug reservoir, clean the unit, and change batteries when necessary.

Clinical trials on pigs are ongoing. Human testing is expected to begin by the end of the year.

Increased intake of vitamin C from the diet, but not from supplements may slash the risk of mouth cancer by 48 percent, says an epidemiological study.

The study, published in the International Journal of Cancer, used data on supplement use and diet for 42,340 men in the Health Professional Follow-Up Study. During the course of the study, 207 oral pre-malignant lesions were documented.

Vitamin C from dietary sources was significantly associated with a reduced risk of mouth cancer, but no association with the vitamin from supplements was found.

Vitamin C is needed to form collagen, a tissue that helps to hold cells together. It's essential for healthy bones, teeth, gums, and blood vessels. It helps the body absorb iron and calcium, aids in wound healing and contributes to brain function.

You can find high levels of vitamin C in red berries, kiwi, red and green bell peppers, tomatoes, broccoli, spinach, and juices made from guava, grapefruit and orange.

Parents may want to save their kids' baby teeth for more than just nostalgic reasons -- they may want to save them because they are rich in stem cells and the pulp tissue could provide the means to treatment for injuries and disease. BioEden Inc. is a new company out of Austin, Texas pioneering this effort that is so new some doubt science will ever catch up with the expectations of this firm. But President Jeff Johnson says all evidence indicates that baby teeth are a wonderful source of stem cells -- cells that doctors and researchers pursue for their capability of replicating and morphing into specialized cells that can be used to repair the body. Experts think baby teeth stem cells might one day be used for bone, teeth, and even nerve cell regeneration which could hold potential for spinal cord injuries and Alzheimer's and Parkinson's diseases.

Parents may find brochures in their dentist offices featuring the benefits of banking their children's teeth once they fall out. And pursuing tooth banking is no different than pursuing any other dental procedure. There are fees involved, of course -- banking fees and perhaps referral fees from dental offices -- and other considerations that each parent must weigh. Dr. Phil Hunke, president of the American Academy of Pediatric Dentistry and pediatric dentist for 32 years, says the idea of removing cells and freezing them holds true promise -- and he may want to bank the tooth of a child or grandchild once he learns more. Dr. Kevin Donly, a professor of pediatric dentistry, says he sees some potential but will not be banking teeth for his three little boys. He just doesn't think he's at the point where it's necessary. Another pediatric dentist -- Dr. John Updyke -- believes that if money were not an issue, all parents should bank their kids' teeth. But many young families can't afford the initial $595 and the $89 annual storage cost it requires. And without a solid scientific backing, tooth banking might not come up as a priority for many when it may take 10 years or more to even determine how useful these specific stem cells will be.

In the knowledge that a picture is indeed worth a thousand words, New Zealand's Ministry of Health wants the health warning on cigarette packs to include large graphic photos of smokers with throat cancer or rotting teeth and gums.

According to the news report, Canada, Australia, Brazil and Thailand have already adopted graphic warnings and many other countries are also considering making the change. I live in the U.S. and I have never seen a pack of cigarettes with a graphic warning such as the one New Zealand is proposing, but I think that it might be more effective than mere wording. I went and searched images with throat cancer and the graphic photos that came up were -- well -- let's just say the damage cigarette smoking can do is not very pretty. I wonder why the U.S. hasn't adopted this same sort of warning campaign?
