Synthetic Tooth Enamel May lead to Resilent Structures

Unavoidable vibrations, such as those on airplanes, cause rigid structures to age and crack, but researchers have found that if you design them more like tooth enamel, it could lead to more resilient structures such as flight computers. Most materials that absorb vibration are soft and don’t make good structural components such as beams, chassis or motherboards. Artificial enamel is better than solid commercial and experimental materials that are aimed at the same vibration damping, as it’s lighter, more effective and less expensive. Researchers from the University of Michigan examined many structures in animals that had to withstand shocks and vibrations: bones, shells, carapaces and teeth. These living structures changed from species to species and over the eons. Tooth enamel told a different story. Under an electron microscope, it shared a similar structure whether it came from a Tyrannosaurus, a […]

Gum Disease Risk Doubles With Frequent Marijuana Use

Marijuana has come a long way from being demonized as an illegal drug. Today, medical marijuana use is legal in 29 states and in Washington D.C. And as of November 2016, eight states made recreational marijuana use legal as well. But despite its praises being sung by millions, marijuana remains illegal under federal law. And for all its purported medical benefits, there are still downsides to marijuana use which advocates conveniently fail to mention in most conversations about the drug. One such downside is the one uncovered by a recent Columbia University study that says frequent pot use doubles the risk for periodontitis, an infection that causes serious damage not only to gum tissue but to the bone that supports the teeth as well. Frequent pot users show signs of periodontitis The study, which was published in the Journal of […]

What to Do In Case of a Dental Emergency

Nobody wants to face a dental emergency, but it happens all the time, and to anyone at that, even people who practice proper oral and dental care. Worse, a dental emergency can take place even when you’re doing something as ordinary as eating popcorn while watching TV. One solid bite down an unpopped corn kernel and you could end up with a cracked tooth or worse. A chipped tooth is just one of many types of dental emergencies. Some experience severely swollen or bleeding gums. Others get several teeth knocked out after a rather violent ice hockey game. These dental emergencies need to be attended to right away, especially those that involve tooth loss. It goes without saying that a knocked out permanent tooth can really hurt, so it’s imperative to do something about the pain and take care of […]

Childhood Sleep Apnea – How can my Child Overcome It?

According to the National Sleep Foundation, Obstructive Sleep Apnea (OSA) affects more than 18 million adults and about 2-3% of children of all ages as well as newborns. This sleep-related disorder causes difficulties during breathing while asleep. It often caused because the muscles in your upper airway relax while you sleep, making it floppy, which tends to make it susceptible to blockage due to the adenoids and tonsils. It is known to run in families, and children who have larger adenoids and tonsils. OSA in babies and toddlers is particularly concerning for parents as such children tend to feel very tired and cranky due to disturbed sleeping patterns and may also face learning, behavioral and health problems in the future. This happens because OSA causes the child’s breathing to temporarily pause while asleep for a little over two breath cycles. […]

Prefabricated blood vessels may revolutionize root canals

Root canals are used to save a tooth that has become infected or decayed, with over 15 million performed each year in the U.S.. However, this procedure can cause teeth to become to become brittle and susceptible to fracture over time. The procedure involves removing infected dental tissues and replacing them with synthetic biomaterials covered by a protective crown. Now researchers in Portland, Oregon, have developed a process by which they can engineer new blood vessels in teeth, creating better long-term outcomes. By removing the tooth’s blood and nerve supply it is without an biological response. Then can cause the tooth to be lost and a need of dentures or implants. The researchers used a 3D printing-inspired process, which was based on their previous work fabricating artificial capillaries, to create blood vessels in the lab. They placed a fiber mold made […]
