Aug. 23, 2022 – Your twice-daily brushing and flossing routine might sometime be automated utilizing tiny microrobots that scrub your enamel for a custom-made clear, due to new analysis from the University of Pennsylvania.

Scientists used magnetic fields to assemble nanoparticles into tiny, brush-like robotic constructions that exactly take away biofilms, a community of germs and different sticky substances, from the surfaces of enamel. They describe their leads to a paper printed within the journal ACS Nano.

The microrobots characteristic bristles that may prolong, retract, change form, and transfer horizontally, vertically, and in circles. The bristles can adapt to every individual’s tooth alignment and get into hard-to-reach areas.

“It could be perfectly aligned teeth or misaligned teeth,” says examine writer Hyun (Michel) Koo, DDS, founding director on the Center for Innovation & Precision Dentistry on the University of Pennsylvania. “It will work in either case because they can adapt to different surfaces, different nooks and crannies.”
While they scrub your enamel, these bristles may also assist to kill germs. That’s as a result of they’re comprised of “iron oxide nanoparticles,” which may activate hydrogen peroxide to assist kill micro organism and degrade biofilms. Another profit: These nanoparticles are cheaper and extra plentiful than many supplies utilized in nanotechnology, like gold and platinum.

“It’s such a basic material,” says examine writer Edward Steager, PhD, a analysis investigator at Penn Engineering. “It’s not even a necessarily fancy material.”

When Will Tiny Teeth-Brushing Robots Be Available to You?

The group is packaging the expertise right into a consumer-friendly prototype, which they hope to have prepared inside a 12 months. But they’ll doubtless want just a few extra years of testing earlier than the robots are prepared for industrial use.

Once absolutely developed, this expertise could possibly be a sport changer for individuals with disabilities, older populations, or anybody who lacks the guide means to take excellent care of their oral well being, says Koo. These populations will doubtless be the primary to check out the system, then others will comply with.

“We started with persons with disabilities or an older geriatric population, but I think at the end of the day, we want this to become available for everyone,” says Koo.

This innovation might change the entire oral care trade, he notes.

“The whole technology of dental plaque control has not been disrupted for, say, centuries,” Koo says. “I mean, essentially, you have a bristle-on-a-stick concept, which has been used since early millennia, you know, and it’s not very effective, right? To the point that you have to actually floss and rinse to make sure that you have effective plaque control. We want to disrupt that. We want to have something that is user-friendly, plug and play.”

Dental floss has been round for a pair hundred years, however solely a few third of Americans floss day by day, in keeping with the CDC. Any plaque left behind after brushing and flossing places your mouth in danger.

“Dental plaque is the source of a number of oral diseases, from tooth decay to gum diseases,” says Koo.

With a exact, efficient option to management oral illness, we are able to defend our total well being, he says. Indeed: Gum illness is linked to coronary heart illness and diabetes.

“Bacteria found in the oral cavity are associated with Alzheimer’s,” Koo says. “So there’s a lot of connection between oral and general health.”

MONDAY, June 20, 2022 (HealthDay News) — Getting your tongue or lips pierced? Don’t be shocked when your dentist is sad about it.

These piercings can do injury to your enamel and gums, a brand new research warns.

“Our research discovered that many individuals with oral piercings had deep pockets and gaps round their enamel, and receding and bleeding gums,” mentioned research creator Dr. Clemens Walter, a professor at University Medicine Greifswald in Germany. “These are all indicators of periodontitis, additionally referred to as gum illness, which might result in tooth loss.”

Walter and his colleagues analyzed eight research that included 408 folks with a mixed 236 lip piercings and 236 tongue piercings. In all, 1 in 5 had multiple oral piercing. The individuals reported having their piercings starting from one month to 19 years, and most folk wore metallic jewellery of their piercings.

The research in contrast enamel and gums subsequent to the piercings with areas elsewhere within the mouth.

Researchers reported that 3 in 5 research discovered deeper pockets round enamel subsequent to tongue piercings, and three in 4 discovered wider gaps between enamel; 2 in 3 discovered bleeding gums, and 4 research on the lookout for receding gums discovered it in all 4.

In addition, 3 of 4 research taking a look at lip piercings revealed receding gums within the space.

The research evaluate was offered Wednesday at a gathering of the European Federation of Periodontology, in Copenhagen. Research offered at conferences is usually thought of preliminary till printed in a peer-reviewed journal.

“The findings recommend that oral piercings, particularly within the tongue, negatively have an effect on the adjoining enamel and gums,” Walter mentioned in a gathering information launch. “In these with tongue piercings, injury was significantly notable across the backside two entrance enamel, referred to as the mandibular incisors, that are vital for biting and chewing meals.”

The chance of tooth and gum injury appeared to extend with time, he added.

His recommendation: “People with tongue and lip piercings ought to take away them to guard their enamel and gums from additional injury,” Walter mentioned.

About 5% of younger adults have oral piercings, with the tongue being the commonest website. Women are about 4 occasions extra more likely to have an oral piercing than males, in line with the research authors.

Previous analysis has yielded comparable findings. Researchers on the brand new research urged dentists to inform their sufferers concerning the danger of issues from sporting oral piercings.

April 28, 2022 – What if cavities or cracked or damaged tooth may very well be repaired with out dental fillings?

Unlike many different sorts of human tissue, dental enamel, the outer layer of tooth, does not regrow as soon as it is broken. Dentists should restore cavities and broken enamel with artificial supplies like ceramics, metals, and resins.

But scientists are learning easy methods to develop dental stem cells in a lab to attempt to remodel how dentists deal with tooth, imagining a future through which tooth enamel or complete tooth may very well be changed.

Scientists have created a 3D mannequin with human dental stem cells they’re working to make use of because the constructing blocks to revive tooth, in line with outcomes of lab experiments reported inCellular and Molecular Life Sciences.

The researchers used stem cells from the dental follicle, tissue that surrounds tooth, to make the 3D mannequin, which may develop extra dental stem cells in a lab.

“It can be an ideal advance within the area if stem cells may very well be used to restore cavities or deal with different oral well being points,” says senior research writer Hugo Vankelecom, PhD, a stem cell researcher on the University of Leuven in Belgium.

“The tooth gives a superb supply of stem cells,” he says, and his staff could make them develop and produce much more cells.

In concept, it ought to be doable for scientists to get dental stem cells from tooth which might be naturally misplaced or surgically eliminated. Then they might freeze and protect the cells with out shedding their skill to develop and regenerate, Vankelecom says.

In the long run, this may imply biobanks routinely retailer tissue from knowledge tooth that get pulled, in order that dentists may use this tissue when oral well being issues develop down the road.

“These cells may very well be utilized to personalize dental therapies,” Vankelecom says.

Fixing Teeth

Of course, many extra lab assessments and medical trials shall be wanted to see if, sooner or later, dentists can use dental stem cells to fill cavities and repair broken tooth safely and successfully.

“Success within the clinic will rely on the benefit of assortment and biobanking, the associated fee, and the eventual high quality of restore,” Vankelecom says.

That mentioned, present strategies for filling cavities and repairing tooth depart rather a lot to be desired, says Ophir Klein, MD, PhD, govt director of Cedars-Sinai Guerin Children’s and an adjunct professor on the faculties of dentistry and drugs on the University of California, San Francisco.

“A tooth that’s handled with a organic versus an inert therapeutic has the potential to stay more healthy and extra resilient,” says Klein, who wasn’t concerned within the new research. “It appears believable to me that in our lifetime, we can have stem cell-based therapies to deal with dental illness.”

Dec. 15, 2021 — It’s no shock that many individuals consider the vacations are meant for us to place apart our dietary senses and bask in all of the yummy meals that we’d keep away from on a traditional day.

While many of those festive treats could trigger critical issues for our tooth, others are filled with vitamins and might trigger little or no hurt.

Classic meals and meals like cranberry sauce, mashed potatoes, or stuffing, whereas scrumptious and comforting, can wreak havoc in your tooth as a result of all of the sugar in cranberry sauce and the variety of carbs in stuffing that may flip into plaque.

But loading up your plate with veggies, turkey, and even inexperienced bean casserole will offer you the well being advantages you want.

So, how are you going to shield your tooth this vacation season whereas nonetheless having fun with the meals we crave all yr lengthy?

Avoid Fermentable Carbohydrates

“Most people think of sugar as being bad for your teeth, whereas fermentable carbs are way worse than regular candy,” says Whitney Rose DiFoggio.

With expertise as a Chicago-based dental hygienist, DiFoggio understands what these fermentable carbs are all about.

“Fermentable carbs are carbohydrates that are broken down by the bacteria in your mouth. Now when this happens, acids are produced in your mouth, which can, unfortunately, quickly lead to tooth decay,” she says.

Examples of those carbs are processed meals like white bread, graham crackers, and cereal, to call only a few.

Fermentable carbs are acidic in nature, and though that’s what’s chargeable for tooth decay, they’re not inherently dangerous.

San Diego registered dietitian nutritionist Wendy Bazilian, a health care provider of public well being, says “they are actually good to an extent because they break down easier and also help to fuel the gut bacteria.”

But their profit is short-lived by the truth that they break down simply. Due to their pro-inflammatory nature, your oral well being could also be affected.

But how do these fermentable carbs really injury your tooth? DiFoggio makes use of white bread for example.

“When bread mixes with your saliva, it turns into a paste, and that paste sticks on your teeth, which increases your oral cavities,” she says.

And can you sweep away these carbs proper after consuming? Yes, though there’s a catch.

DiFoggio says that you just need to wait half-hour after consuming earlier than you sweep.

 “If you don’t wait 30 minutes, you might erode your enamel because the food you eat is mostly acidic. And these acids could soften your tooth enamel,” she says.

What to Do Instead

Nona Djavid, a vitamin and weight reduction skilled in California, says that you may “drink plenty of water and add foods to your diet that are rich in calcium to negate the acidity.”

She says that you need to “take these carbs with the main dish (especially food rich in calcium), take a spoonful of yogurt after eating, and rinse your mouth with water.”

DiFoggio demonstrated find out how to nonetheless eat these carbs and preserve nice oral hygiene.

“Although it is easier said than done to limit snacking, try to avoid snacking frequently,” she says. “Instead, you can try taking in all the ‘junk’ at once with your main meal. Also, consider drinking lots of water throughout the day to wash away the food debris from your teeth.”

“Water can sneak into the crevices of your teeth and gums and help rinse off the food particles, residue, and remnants from your bites and chews. It helps wash it all down — or when brushing and rinsing, spit it all out,” Bazilian says

As a nutritionist, she provides that “eating cheese at the end of the meal can help bring the pH of the mouth back up faster toward neutrality.”

The Way Forward This Holiday Season

“Everyone deserves to indulge. However, we often feel guilty when we do. Even if you’re enrolled in a weight loss program, you are absolutely allowed to treat yourself this holiday season,” says Djavid.

The key ingredient is to mentally put together your self to be able to keep away from guilt. Experts say that it’s finest should you select a time to bask in all of the goodies over the vacations. Djavid recommends consuming heavier meals and drinks intermittently (for instance, 3-5 p.m.). Just don’t be on a roll for 12 hours. 

Swap the cocktail for soda water blended with liquor or different drinks like laborious seltzers and kombuchas. Don’t overlook to convey your individual snacks! A bag of carrots or baked candy potato chips can go a great distance. 

As the proprietor of a weight reduction program, Djavid paves a means for consuming the fitting means. “If you’re going to taste various meals, try smaller portions so you don’t feel restricted, versus overindulging on one item. One bite of a delicious cookie isn’t going to kill your diet.”

Bazilian reminds us that “the mouth is a gateway to our health.” Remember that it’s the solely place the place you’ll be able to chew and kick off digestion to nourish each cell and organ in your physique — so holding it wholesome is necessary.
