FDG-PET study finds side-by-side correlation of periodontal disease, carotid plaques
Cardiovascular Business    Share   Share on FacebookTwitterShare on LinkedinE-mail article
FDG-PET measurements of metabolic activity within periodontal tissue correlate with macrophage infiltration within carotid plaques, which researchers said provides "direct evidence for an association between periodontal disease and atherosclerotic inflammation." The study was published in the Feb. 22 issue of the Journal of the American College of Cardiology. Some evidence has established periodontal disease as an important risk factor for atherosclerosis, and FDG-PET is an established method for measuring metabolic activity in human tissues and blood vessels. Therefore, Kenneth M. Fifer, BA, and colleagues from the division of cardiology in the cardiac MR-PET-CT program at Massachusetts General Hospital in Boston, aimed to test the hypothesis that metabolic activity within periodontal tissue (a possible surrogate for periodontal inflammation) predicts inflammation in a remote atherosclerotic vessel, utilizing 18F-FDG-PET.

Despite research on gum disease prevention, treatment is still a priority
SBWire    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In spite of encouraging news about a link between gum disease prevention and the intake of omega-3s that was published recently in the Journal of the American Dietetic Association, Dr. Alex Farnoosh says the priority at his practice remains gum disease treatment. Farnoosh is passionate about the science of dental care. As a cosmetic dentist and periodontist, his focus is on improving aesthetics and protecting health. "Even though new strategies like increasing omega-3 intake are encouraging, we haven't found a way to prevent gum disease completely," Farnoosh says. "The reality today is that the majority of my patients have some form of gum disease and they need treatment. That's why I continue to refine techniques for gum surgery and laser dentistry." More

What causes chronic bad breath, and what's the best cure?
The Boston Globe    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Q: What causes chronic bad breath, and what's the best cure?
A: While everyone can expect some unpleasant odor after polishing off a meal laden with garlic or spices, bad breath from food should disappear within about 24 hours, after your body has fully processed the meal. When bad breath keeps returning, it's usually because of lingering bacteria in the mouth, says James Hanley, periodontist and an associate dean at Tufts School of Dental Medicine. The mouth is home to a complex mix of bacteria, which form communities on surfaces and in crevices of teeth, gums and the tongue. The bacteria feed on particles of leftover food, and produce chemical byproducts that leave an odor.

Research: Physicians using social media need more oversight
George Washington University    Share    Share on FacebookTwitterShare on LinkedinE-mail article
New research, conducted by Katherine Chretien., M.D., F.A.C.P., associate professor of medicine at George Washington University School of Medicine and Health Sciences, reveals that while social media has the potential to have a positive social impact, there is need for greater accountability and guidelines, as some physicians who are regular users of Twitter are disseminating unethical and unprofessional content. A research letter titled, "Physicians on Twitter," was included in the Feb. 9 issue of The Journal of the American Medical Association. "This research helped us to identify how physicians are using social media and has helped us gauge whether or not there is need for greater accountability for physicians who use social media," Chretien said.

Telephone triage for dental emergencies
Dentaltown    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The word "triage" is derived from the French word "trier," meaning to separate, sort or select. Most of us are familiar with the triage process that takes place in hospital emergency rooms. It is a process of determining the priority of patients' treatments based on the severity of their condition. Put another way, triage is the initial assessment of a situation in order to determine the patient's need and the course of action to follow. Whenever a patient presents to our dental offices with a dental emergency, the dentist or dental staff routinely perform triage to ascertain the extent and nature of the patient's problem and implement treatment to effectively diagnose and resolve the problem. Our objectives for an emergency appointment are to relieve our patient's pain or otherwise resolve their problem with efficient use of staff and doctor time. More

Dr. Rebecca Gelber: Can gum disease actually kill you?
North Lake Tahoe Bananza    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Gingivitis isn't something most of us spend much time thinking about. We dutifully sit through lectures to floss during our routine dental cleaning — it's not like we have much choice, given the sharp metal bits they have stuck in our mouths. But do we really care? It's not like gum disease is going to kill us, right? Maybe it will. New studies are looking at ties between gum disease and life-threatening conditions including heart attack and stroke. Mechanisms still are being investigated, but it is clear that those with the most gum disease double their risk of heart attack, and possibly stroke and other clotting conditions. Many researchers think that bacteria in our mouths can enter the bloodstream and travel to other body sites and cause damage directly. More

Dry copper kills bacteria on contact
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Metallic copper surfaces kill microbes on contact, decimating their populations, according to a paper in the February 2011 issue of the journal Applied and Environmental Microbiology. They do so literally in minutes, by causing massive membrane damage after about a minute's exposure, says the study's corresponding author, Gregor Grass of the University of Nebraska-Lincoln. This is the first study to demonstrate this mechanism of bacteriocide. "When microbes were exposed to copper surfaces, we observed contact killing to take place at the rate of tens to hundreds of millions of bacterial cells within minutes," Grass says. "This means that usually no live microorganisms can be recovered from copper surfaces after exposure." More



US senators: Ban tobacco from baseball

Two US senators have called for a ban on the use of tobacco, including smokeless products, in professional baseball, citing the athletes' role-model appeal to young Americans. Democratic Sens. Dick Durbin and Frank Lautenberg made the appeal in letters to the sport's commissioner, Bud Selig, as well as the head of the players association, Michael Weiner. "We write to ask that Major League Baseball prohibit the use of tobacco products on the field, the dugout and the lockers rooms at all venues," wrote the lawmakers. "While tobacco companies spend millions on ads tailored to attract young people to use tobacco products, MLB is undoubtedly complicit in attracting many young people to try smokeless tobacco after seeing their baseball heroes chew tobacco."

Lack of dentists, dental insurance compound dental health problem
St. Louis Post-Dispatch    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When people are making health care decisions based on cost, dental care often doesn't make the cut. Missourians have some of the nation's worst dental health. The state ranks 47th in percentage of adults who have visited the dentist in the last year (63 percent). The national average is 71 percent, according to the Kaiser Family Foundation. Illinois ranks 32nd, with 69 percent of adults visiting the dentist. And it's not just adults. In 2004, a survey found that one quarter of Missouri's third-graders had untreated tooth decay. A shortage of dentists has compounded the problem, especially in rural or underserved areas. There are 18 Missouri counties with one or no registered dentists. More

Dr. Roger P. Levin: Get back to basics — and practice growth
Dental Economics    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In spite of a challenging economy, dentistry as a profession is in good shape, especially compared to many industries. According to the 2010 Dental Economics®/Levin Group Annual Practice Survey, nearly 60 percent of respondents said they expected their gross production to increase compared to the prior year. However, many dentists rightly are concerned about their ability to maintain and grow a highly productive practice. At a recent seminar, a dentist asked me, "Is it possible for my practice to grow in this economy? I've tried radio ads, setting up a Facebook page, and offering discounts for new patient exams, but nothing seems to work for long." My answer was yes, practices can grow and continue to grow if they have the right targets. Despite the current economic conditions, many Levin Group clients are increasing their annual production by 15 to 20 percent or more, which means growth is certainly possible. More

Cheap dental care in Mexico draws visitors from US, Canada
The Gazette    Share    Share on FacebookTwitterShare on LinkedinE-mail article
"Hey, meester! Do you need a good dentist?" Walking through the streets of this sun-drenched Mexican town is a bit like walking through a carnival midway. Hucksters are everywhere hawking their wares in full voice. They're pitching bargain-priced pharmaceuticals like Viagra and Zantac and low-cost eyeglasses and everything else from hats to holsters, but the competition is fiercest over dental services. This border town in the northern Mexican state of Baja California is touted as having the highest number of dentists per capita in the world. Locals say during the peak winter season when the town population swells from 4,000 to about 8,000 residents, as many as 350 dentists ply their trade out of more than 200 clinics. More
