Philadelphia Inquirer: HPV is causing an oral cancer epidemic in men by outwitting natural defenses

Five years ago, when actor Michael Douglas candidly revealed that his throat cancer was linked to having oral sex, two things happened.

He made headlines that mortified his family. And he helped publicize the fact that a pervasive, sexually transmitted virus called HPV was unleashing an epidemic of oral cancer among men.

Compared with women, men are more likely to get infected with HPV — including “high-risk” cancer-causing strains. They also are less able to wipe out infection on their own, and more likely to get reinfected. The reasons are unclear.

Your dentist should play a key role in detecting oral cancer.  Having an thorough oral cancer screening is the first step to catching this dangerous cancer early. 

Did you know that Dr. Henley is the ONLY general dentist in Jacksonville that serves on the Head and Neck Tumor Board at Baptist MD Anderson?  The tumor board is a multi-specialty group that works together using the latest in dentistry and medicine to ensure that cancer patients have the best possible outcomes.

Red wine compound could help tooth decay and gum disease

Red wine has previously been linked to a range of supposed health benefits, from helping the heart to lowering the risk of diabetes.

Now a new study suggests it contains chemicals that can help in the fight against tooth decay and gum disease. Researchers found compounds from the drink, known as polyphenols, helped fend off harmful bacteria in the mouth. But experts warned that the findings do not offer a "green light" to drink more red wine.

Previous studies have suggested that the health benefits of polyphenols are linked to them being antioxidants that protect the body from harmful free radicals. However, recent studies have indicated that polyphenols might also boost health by working with "good bacteria" in our gut. For this study, in the Journal of Agricultural and Food Chemistry, scientists looked into whether wine polyphenols might also be good for oral health.

Researchers compared the effects of two polyphenols from red wine against grape seed and red wine extract supplements on bacteria that stick to teeth and gums and cause dental plaque, cavities and gum disease. They found the wine polyphenols and extracts all reduced the bacteria's ability to stick to the cells, but the polyphenols - caffeic and p-coumaric acids - were more effective.

When combined with the Streptococcus dentisani - believed to be an oral probiotic, which stimulates the growth of good bacteria - the polyphenols were even better at inhibiting the pathogenic bacteria. The findings, they said, could ultimately lead to new dental treatments.

Red wine is rich in polyphenols but they are also found in a range of other drinks and foods.

• Drinks
• Coffee
• Green tea
• Black tea
• Cider
• Orange juice and lemon juice
• Foods
• Blueberries
• Raspberries
• Kiwis
• Black grapes
• Cherries
• Beans

Wine in moderation

The report's authors acknowledge that their study was limited by the fact it was done outside of the human body with cells that simulated gum tissue. And they said further research was needed to determine more about what was causing the bacteria to be inhibited. They said metabolites which form when the digestion of polyphenols begins in the mouth could also be responsible for some of the effects in the study.

The British Dental Association's scientific adviser, Professor Damien Walmsley, said the study was "interesting" but it did not mean people should start drinking more. "In fact, the acidic nature of wine means that consuming a lot of these drinks will damage the enamel of the teeth," he said. "Therefore, until the benefits of this research are shown clinically, it is best to consume wine in moderation and with a meal to minimise the risk of tooth erosion."

Naveed Sattar, professor of metabolic medicine at the University of Glasgow, said the research was "interesting" but still "very preliminary". "However, the findings do not support drinking more red wine to stop people getting infections," he said. "There is no good evidence that drinking wine per se is overall good for health - on the contrary, more and more evidence from other sources now suggests the less wine or alcohol one drinks, the lower the risks of range of disease and the lower the mortality risks."

History of Gum Disease Increases Cancer Risk in Older Women

Postmenopausal women who have a history of gum disease also have a higher risk of cancer, according to a new study of more than 65,000 women.

The study, led by researchers at the University at Buffalo, is the first national study of its kind involving U.S. women, and the first to focus specifically on older women. It's also the first study to find an association between periodontal disease and gallbladder cancer risk in women or men. The findings were published today (Aug. 1) in the journal Cancer Epidemiology, Biomarkers & Prevention.

"This study is the first national study focused on women, particularly older women," said Jean Wactawski-Wende, the study's senior author.

"Our study was sufficiently large and detailed enough to examine not just overall risk of cancer among older women with periodontal disease, but also to provide useful information on a number of cancer-specific sites," added Wactawski-Wende, dean of UB's School of Public Health and Health Professions and a professor of epidemiology and environmental health.

Sharks May Have the Healthiest Teeth in the Animal Kingdom

You’d think with all those seals, fish and the occasional surf board, sharks’ teeth would be a mass of cavities and bad dental hygiene. Not the case. Sharks may have the healthiest teeth in the animal kingdom, it turns out. Scientists just found that their pearly whites contain fluoride, the active ingredient in most toothpastes and mouthwashes.

Discovery News reports: “(The surface of) shark teeth contains 100 percent fluoride. In principle, sharks should not suffer from cavities. As they live in water and as they change their teeth regularly, dental protection should not be a problem for sharks.”

Unfortunately for humans, we missed out on this feat of evolution. Our teeth contain hydroxyapatite, which is an inorganic substance also found in bone. In other words, not cavity resistant in the least. And let’s not forget that, in addition to their unique cavity-preventing composition, sharks have the ability to replace their teeth time and time again. When it comes to dental matters, sharks have the edge

E-cigarettes 'just as harmful as tobacco' for oral health

E-cigarettes 'just as harmful as tobacco' for oral health

In an article published by Medical News today discussed that  a recent study found that the chemicals present in electronic cigarette (e-cigarette) vapor were equally as damaging - in some cases, more damaging - to mouth cells as tobacco smoke. Such damage can lead to an array of oral health problems, including gum disease, tooth loss, and mouth cancer.

E-cigarettes are battery-operated devices containing a heating device and a cartridge that holds a liquid solution. The heating device vaporizes the liquid - usually when the user "puffs" on the device - and the resulting vapor is inhaled.

While e-cigarette liquids do not contain tobacco - a highly harmful component of conventional cigarettes - they do contain nicotine and other chemicals, including flavoring agents.

According to the Centers for Disease Control and Prevention (CDC), the use of e-cigarettes has increased in recent years, particularly among young people. In 2015, 16 percent of high-school students reported using the devices, compared with just 1.5 percent in 2011.

FDA: No More Antibacterials In Consumer Soaps

In an article published today on NBC News  the FDA has ordered antibacterials from consumer soaps. The Food and Drug Administration says they do little or nothing to make soap work any better and said the industry has failed to prove they're safe.

Companies will have a year to take the ingredients out of the products, the FDA said. They include triclosan and triclocarban. Soap manufacturers will have an extra year to negotiate over other, less commonly used ingredients such as benzalkonium chloride.
