Fluoride Treatment for Adults? – Newton, Wellesley, MA

If the high-pitched whir of a dentist's drill as it bores into your molar terrifies you, good news! There could be fewer fillings in your future. According to Dr. Ryne Johnson, prosthodontist and managing partner at Newton Wellesley Dental Partners, “A painless way to prevent cavities in adults is gaining traction”. Project1 Fluoride varnish is standard practice for children's teeth, and is generally done yearly.  According to Dr. Johnson, “many of my older patients are on medications that cause dry mouth, which puts them at high risk for cavities. So for these patients, we use a skinny brush and a little pot of yellowish liquid and paints the varnish on the teeth. We know that saliva helps us wash away bacteria and food in the mouth, and the fluoride varnish will help that.  Sometimes we use a tray to carry the fluoride". One way fluoride helps is by seeping into the enamel and drawing the calcium and phosphate that's naturally present in the saliva. The minerals boost the teeth's natural healing process and make them more resistant to future decay. But there are other theories about how fluoride works. It strengthens the enamel before the tooth erupts, which is why it's so important for children. And it attacks the acid-producing bacteria in the mouth. One study shows fluoride makes it more difficult for these bacteria to stick to the teeth. It takes about a minute, and the fluoride treatment is done. Some patients are also given a prescription for a concentrated fluoride gel that can be used at night. "These preventative approaches work on adults just as well as they do on children," says Norman Tinanoff, a professor of pediatric dentistry at the University of Maryland. He says part of what's making fluoride treatments popular for adults is a move to make dental care personal, with an individual treatment plan for each patient. To do that, you have to weigh a patient's risk of getting cavities. One of the biggest proponents of this approach is John Featherstone, dean of the University of California, San Francisco School of Dentistry. Featherstone came up with a comprehensive way of measuring a person's risk for caries, or tooth decay. It includes testing the level of bacteria in the mouth, and looking at dietary habits, medical conditions, medications, saliva flow and history of tooth decay. When Featherstone put his patients on personal treatment plans, he found the strategy worked. "It really proved that drilling and filling did not fix the disease," Featherstone says. "Putting in a filling fixes that hole in the tooth, but it doesn't deal with the bacteria in the rest of the mouth." Most bacteria are friendly, but a couple of bad actors can cause cavities. These guys feed on sugars and expel acid that eats away at the enamel. Traditionally, dentists were taught that the only way to deal with decay was to drill it out. That's still important in some cases, Featherstone says, but without fixing the underlying problem of bad bacteria, patients just keep coming back for more fillings. Featherstone saw another way. "It's a little bit like your car is starting to rust," he says. "If you can stop the rust before the rust goes right through the body of the car, then you're in good shape." Like rust, tooth decay is a slow process. A full-on cavity is a hole that needs to be fixed. But if you catch decay early, Featherstone says, it can be reversed using fluoride treatments like varnish and concentrated toothpaste and gels. "In the past we believed tooth decay was a rapidly progressive disease. But research shows it's slowly progressive," says Wendell Evans, associate professor of dentistry at the University of Sydney in Australia. He recently published a study that found using these techniques reduced the need for fillings in adults by 30 to 50 percent. Striking as these results seem, the concept isn't new. This shift to a preventive model of dentistry is decades in the making. "Some of the stuff in our study has been known for 50 years," Evans says, referring to the use of fluoride treatments. "Prevention has always been a part of the world of dentistry," says Richard Valachovic, president of the American Dental Education Association. "What we're seeing is a generational shift," Valachovic says. As dentists have come to better understand the microbiology of the mouth, more effective preventive techniques have followed. At this point, Featherstone says, two-thirds of dental schools in the U.S. teach some kind of disease management model based on a thorough risk assessment. And he expects that at some point all dentists will follow a preventive protocol.  "It will happen," Featherstone says. "It's just a matter of time."

A Cancer Screening from Saliva?

Project1 According to Dr. Ryne Johnson, prosthodontist and managing partner at Newton Wellesley Dental Partners, “A 10-minute cancer test which can be taken at home using just a drop of may be the wave of the future”. Scientists at California State University says it is possible to detect tumor DNA when is it circulating in bodily fluids – an approach known as a liquid biopsy.  The saliva test is 100 per cent accurate and is so simple that it could be carried out at a pharmacist, the dentist or even in the privacy of someone's own home if they were concerned. Currently scientists can only use blood tests to detect cancer if they have already taken a biopsy and sequenced a tumor, so they know which genetic signature to look for. Although this can be used to monitor cancer spread it cannot be used for an initial test. And it can throw up false positive. Tests have shown that just a single drop of saliva contains enough data to give a definitive diagnosis as soon as a tumor develops, he said. The test is non-invasive and cheap, costing around just $20. It is due to enter full clinical trials in lung cancer patients later this year, and is expecting approval within two years from the Food and Drug Administration in America. “If there is circulating signature of a tumor in a person blood or saliva, this test will find it,” research scientists told the American Association for the Advancement of Science annual meeting in Washington. “We need less than one drop of saliva and we can turn the test around in 10 minutes. It can be done in a doctor’s office while you wait. “Early detection is crucial. Any time you gain in finding out that someone has a life-threatening cancer, the sooner the better. With this capability, it can be implemented by the patient themselves in a home check, or dentist or pharmacy.” The test looks for genetic mutations in blood plasma which are consistent with a tumor. “The advantages of this technology is that it is non-invasive. If you have a credible early screening risk assessment technology that people can use on their own or at dentists’ office or pharmacists - that’s the key, early detection.” For more information or for other blogs of interest, visit:  www.NewtonWellesleyDentalPartners.com   Original article at:  http://www.telegraph.co.uk

Sleep Apnea – treatment via a dental appliance

Dr. Ryne Johnson, prosthodontist at Newton Wellesley Dental Partners has been treating sleep apnea and finding success with something besides c-pap therapy (which involves putting a mask on overnight). Project1 A 54 year-old patient (name withheld for HIPAA compliance), wakes up every day ready to put his life on the line as a Newton police officer, but there was something draining his energy. "I was constantly fatigued and my wife and co-workers would say, 'Hey, you snore really loud,'” reports one of the city’s top-cops. That snoring revealed a bigger problem: sleep apnea. "The soft palate or the tongue will collapse and actually stop the air from moving," explains Dr. Johnson. "picture a garden hose kinked with no flow -- that's sleep apnea." Dr. Johnson reports an increase in the number of sleep apnea appliances done in his practice and he's finding success at treating it with something known as SUAD appliance. "What they do is limit the ability for one to open typically and it gently holds the lower jaw forward in a position to get the tongue out of the airway," says Dr. Johnson. “The small device is placed inside the mouth during sleep, which is much easier to tolerate for patients who tried the traditional and cumbersome c-pap. "It's night and day," according to the patients Dr. Johnson works with on these sleep apnea appliances.  For one of Newton’s ‘finest’, "I wake up in the morning. I feel refreshed. I didn't even realize how tired I was all the time until my body adjusted to it. It literally changed my life completely." For additional information visit:  www.NewtonWellesleyDentalPartners.com
