Study shows oscillating power toothbrushes superior

NEW YORK (Reuters) – Use of a certain kind of power toothbrush each day could keep the dental hygienist at bay.
People who wake up in a cold sweat at the thought of dental assistants with sharp instruments hacking away at plaque on their teeth, or those simply interested in the most efficient method of daily dental care, should use a power toothbrush with rotational/oscillation action, according to a new report.
The finding, announced at a symposium in Boston on Saturday, comes from the oral health wing of the Cochrane Collaboration, an international nonprofit organization that compiles and reviews data from healthcare studies.
Rotational oscillation toothbrushes–those that rotate in one direction and then the other–removed up to 11% more plaque and reduced bleeding of the gums by up to 17% more than manual or other power toothbrushes, according to results compiled by the Manchester, England-based Cochrane Oral Health Group, which analyzed data from clinical trials conducted over 37 years.
The Cochrane study extracted data from reports on 29 clinical trials involving 2,547 participants in North America, Europe and Israel. Some of the trials dated back to 1964, while others contained data from as recently as 2001.
The trials compared the effectiveness of all forms of manual and six types of power toothbrushes with mechanically moving heads used over one-month and three-month periods.
According to the findings unveiled at the conference sponsored by the Forsyth Center for Evidence-Based Dentistry, only the rotational oscillation toothbrushes proved more effective than manual toothbrushes in reducing plaque and gingivitis. The results did not explain why the rotational oscillation toothbrushes were more effective than power toothbrushes with only circular or side-to-side motion.
While the study does not deal with long-term benefits to dental health, Richard Niederman, a periodontist and director of the Forsyth Center, called it “a huge first step.”
The next step, he said, would be a review of use of the toothbrushes over three or five years.
“They reduce bacterial plaque that causes disease,” he said of the rotating oscillating brushes. “The next thing to see is do they really reduce cavities or periodontal disease?”
The motion of power toothbrushes is up to 100 times that of manual brushing, Niederman said.
Dr. Kenneth Burrell, senior director of the Council on Scientific Affairs for the American Dental Association, said the findings, if they prove accurate, could be useful in helping dentists make recommendations to their patients.
“That still doesn’t mean that every man, woman and child should abandon the toothbrush that they’re currently using,” Burrell said.
“Someone using the simplest manual toothbrush with good knowledge of how to brush and conscientious brushing can do just as well as somebody using a power toothbrush regardless of the design,” Burrell said.
There are two parts that make up the effect of toothbrushing, Burrell explained. “One is the device you use, and the other is the person attached to device.”
If you brush incorrectly, it doesn’t matter what kind of toothbrush you use, he said.
“What this review is telling you is that an average person putting in an average effort is going to see a better effect than using other brushes.”
Said William Shaw, who helped compile the data for the Cochrane Collaboration: “If you can afford a rotational oscillating power toothbrush and it feels good to you, it offers modest improvement in ability to clean your teeth.”

Congratulations on this exciting and busy time of your life! You have so much to think about during pregnancy but don’t forget about your teeth and gums. It may be easy to overlook your mouth, but all the changing hormone levels that occur with pregnancy can actually make some dental problems worse. Brushing and flossing contributes to your overall health, too, and if your mouth is healthy, it’s more likely that your baby’s mouth will be healthy.
See your dentist
It’s important to continue to see your dentist during pregnancy for oral examinations and professional teeth cleanings. Make sure to tell your dentist that you are pregnant and about any changes you have noticed in your oral health. Good daily care is vital. That means always brushing your teeth twice a day with fluoride toothpaste, cleaning between your teeth once a day, eating a balanced diet and limiting between-meal snacks.

Dentists (a.k.a. we’re real doctors, I promise!) might soon be your first line
of defense against cancer through something called salivanomics—meaning
analyzing your spit to see if you have diseases.
UCLA researcher Dr. David Wong argues in a new paper published in the Journal of
the American Dental Association that in saliva lie a number of health
indicators. PopSci explains salivary diagnostics:
Human saliva is made up of molecules, after all, and in those complex molecules
doctors or dentists looking for the right things can find everything from
proteins to DNA to RNA—or basically the entire genome and a slew of other
supporting characters. With these molecules identified and isolated researchers
can then apply any number of scientific tools to them—things like gemomics,
proteomics, and transcriptomics.
Most of us see our dentists more often than we see our regular doctors, and
running tests on a simple mouth swag to check for diseases is not at all
invasive, and in some cases, just as effective testing blood or other bodily
fluids in the diagnosis process. This isn’t something that’s being implemented
quite yet, but it should be; the next time you have a dental exam, you could be
caring for your overall health as well. And it might make you schedule that
teeth cleaning on time for the first time in your life. [UCLA via PopSci]

Good News for Chocolate Lovers
Know that guilty feeling that creeps in every time you bite into a piece of chocolate? Turns out it’s all for naught. (Well, mostly.) Recent studies show that chocolate is actually good for your teeth – and your overall health.
It turns out that chocolate contains powerful antioxidants
called polyphenols and flavanols. Polyphenols prevent bacteria from turning the sugar and starches contained in chocolate into acids that cause decay. They can help reduce the chances of hypertension and stroke and may even help protect the heart. Dark chocolate is particularly high in flavanols – and has more antioxidant power than green tea.
The cocoa butter contained in chocolate also packs a healthy punch. When you eat a piece of chocolate, the cocoa butter in it coats your teeth, preventing plaque
from sticking to your teeth. And what about the “butter” part of cocoa butter – should you worry about fat? Nope. This kind does not raise cholesterol.
Now for the Bad News
Chocolate is high in calories; one 1-ounce piece of dark chocolate can contain 150 calories or more. So if you’re watching your waistline, you’ll have to control yourself. Plus, to benefit from chocolate’s goodness, all you have to do is eat three 1-ounce pieces of it a week.

There may be a clear reason why there as an increase in gum disease risk for
pregnant women: higher estrogen levels.
A research team recently concluded that women are at increased risk of gum
disease when estrogen levels are raised. Regardless of trimester, the study
found pregnant women are at a higher risk for gum disease based on estrogen
The increased risk of developing gum disease for pregnant women is not a new
fact. The impact of estrogen, however, on gum disease risk was is still a
relatively unknown factor. This University of Helsinki study explored the
possible impact of hormones on gum disease.
If proven to be definitively true, this information could be vital in the way
pregnant women are treated regarding their oral health. It’s even more essential
for pregnant women to visit the dentist regularly compared to everyone else.
If gum disease persists in a pregnant woman, the results could be disastrous,
with issues like premature birth and complications during labor, among others.
