12 FEBRUARY 2011 LINK BETWEEN COFFEE AND DENTAL CARE: LOWER YOUR ORAL CANCER RISK SEVEN RURAL AND REMOTE REGION STUDY GRANTS AVAILABLE IN 2011 DENTAL FILES THIS MONTH PROGRAM 1, 2011 Studies have already shown that coffee may benefit dental care by reducing the risk of developing cavities. Researchers have now discovered that drinking a lot of coffee actually lowers your risk of mouth and throat cancer. According to the findings featured in WebMD, people who drink more than four servings of coffee daily have nearly a 40 per cent lower chance of contracting mouth or throat cancer when compared to people who don't drink coffee. For those who drank less than five cups of coffee daily, the level of protection fell to still significant 4 per cent lower odds for contracting mouth and throat cancer for each cup of coffee consumed each day. Protection for oral and pharyngeal cancer was evident, but protection against cancer of the larynx was not. Coffee's protective effect was shown to remain intact even for drinkers and smokers, despite the fact that tobacco and alcohol consumption are linked to head and neck cancers. Additionally, the protection effect didn't demonstrate a boost by consuming fruits and vegetables, which are also known to protect against head and neck cancers. The researchers at the University of Milan reached these findings when they analyzed nine studies comparing 5,139 people with head and neck cancer to 9,028 people without cancer. So, which ingredient in coffee is responsible for reducing the risk of oral cancer? The study dismissed caffeine as a likely possibility since drinking tea, even in mass quantities, was not protective. The researchers pointed out that coffee contains hundreds of chemicals. Of those, cafestol and kahweol have anti- cancer properties. However, future studies will have to determine more decidedly if these chemicals actually protect against cancer in people. Previous studies in Wired Magazine have credited Trigonelline, an alkaloid, in coffee as a cavity-fighting agent. While the ingredient is recognised for giving coffee its taste, it's also proven to prevent craters from forming in teeth, averting the cavity-causing bacterium Streptococcus from attaching to teeth. Applications for the 2011 ADA Study Grants for Dental Students from Rural and Remote Regions of $5,000 are now open. This year, seven Grants will be available. Each applicant must comply with criteria set out in the Guidelines which are available, together with appropriate Application Forms, from the ADA Inc. and/or the deans of the dental schools. The closing date for applications is 31 March 2011. Visit www.ada.org.au Dental Files returns for 2011. The CD on the cover this month will give you a great start to the new learning year with six experts covering a variety of clinical and research topics. CONE BEAM TECHNOLOGY -- JUST A STROLL ON THE BEACH? Not really, but the radiation dose is reduced compared to 'medical' CT. The burgeoning market in dental cone beam machines needs to be approached with caution, as well as enthusiasm. Dr Dale Myles spoke to Patrick Meaney after his lecture at the 2010 Quintessence meeting in Sydney. IS GOLD ALL THAT GLITTERS? Dr Stephen Travis thought so when he started working as a prostho, but he caught the twin bugs of technology and instant ceramics. Talking to Patrick Meaney at the 5th CAD CAM Convention in Sydney, he discusses the ultimate in 'do it yourself' aesthetics, eMax and other matters reconstructive. WHEN ALL YOU HAVE IS A HAMMER... For even an osseous mallet and an osteotome, ridge expansion is challenging for even the best surgeons.

WHO'D BE A DEAN? Professor Chris Peck, that's who. Chris reveals his plans for Sydney University to Patrick Meaney after taking the reins of the state's oldest dental faculty.
