Don't scrub: Many get it wrong when it comes to tooth-brushing technique

Don't scrub: Many get it wrong when it comes to tooth-brushing technique    BY HELEN BRANSWELL, THE CANADIAN PRESS MARCH 10, 2014   TORONTO - Watching people brush their teeth in movies or on TV can really irk Dr. Andrea Johnstone.A Toronto-based periodontist with a gleaming smile, Johnstone says the technique on display is often the very approach dental professionals warn their patients not to use."They are generally doing the scrub-brush method of just back and forth scrubbing their teeth. Even sometimes on toothpaste commercials. It drives me nuts, actually," she admits.It's an illustration of a common problem. Everyone thinks they know how to brush their teeth. Heck, it's one of the first skills we learn in childhood, one we use — or should use — at least twice daily every day of life.But many people don't actually use the right tooth-brushing technique, which can lead to cavities, tartar buildup and gum disease.So what are we doing wrong? The most common shortcomings relate to the motion used and the length of time we spend on each brushing session, experts say."The tendency is for people to be far too quick when they brush their teeth, to actually not take the 2 1/2 to

Mouthguards and Concussions

By Sassa Akervall, February 25, 2014 -- To answer the question posed in the title, to be perfectly blunt -- no, they can't. The truth is that the whole notion of mouthguards protecting your head is just that -- a notion. Jan Akervall, MD, PhD, the inventor of the SISU Mouth Guard has been asked numerous times if a mouthguard protects against concussions. "Preliminary laboratory studies from the '60s (Stenger 1964 and Hickey 1967) indicated decreased forces transferred to the skull and decreased intracranial pressure from impacts to the jaws when a mouthguard was in place," Akervall said." These were cadaver studies and neither Stenger nor Hickey claimed mouthguards would prevent concussions in real life. These and other small, experimental studies have been used in advertisement for mouthguards to prevent concussions and that is very unfortunate." Sassa Akervall Sassa Akervall. Akervall continued, noting that the question of concussion protection continues to arise. "Many of our athletes keep asking if our product protects against concussions. Being 30% to 50% stronger than conventional mouthguards made of EVA [ethylene vinyl acetate], you may think that the shock-absorbing properties of the guard would stop the forces that transfer to the brain. Unfortunately, that's not true. It's not the case

Finally a Hard Tissue Laser that Cuts Like a Dental Handpiece

  Emmott On Technology: Finally a Hard Tissue Laser that Cuts Like a Handpiece People do not like having dental work done. They do not like getting stuck with a needle. They do not like feeling numb with a fat lip for hours, and they do not like the sound and feel of the “drill” in their mouths. None of this is a surprise to dentists. We know people do not like what we do, and the profession has been struggling for years to invent a way to deliver care with less fear and discomfort. If we could prepare a tooth with no needle, no pain and no whining vibrating drill it would fundamentally change the patient experience. Dental lasers have the potential to provide a pain free drill free experience, but early attempts to use lasers to prepare teeth have been limited. A new dental laser, the Solea from Convergent Dental, looks like it actually works. Solea was launched in the fall and will next be on display at the Yankee Dental Congress in Boston Jan. 29 – Feb. 2. Solea uses a CO2 laser producing a unique 9.3 micron wavelength to actually cut, or more accurately ablate the tooth. The 9.3 micron wavelength matches the peak absorption of hydroxyapatite. Other hard tissue

The Most Influential Person in the History of Dentistry - was not a dentist!

The Most Influential Person in the History of Dentistry - was not a dentist!  I found out about this in the most surprising way.  I was reading the book The Power of Habit, by Charles Duhigg and I was introduced to Claude Hopkins.  He was the most influential man in dentistry.  Ironically, he was a marketer, not a dentist.  He was considered one of the most influential marketing experts of his time as well. How was he the most influential person in the history of dentistry?  His marketing campaign helped to create the habit of daily toothbrushing. In the early 1900's, tooth decay was rampant in America.  It was so bad that it had become an issue of national security.  There were so many WWI recruits with oral infections that they were hampered in pain and could not perform on the battlefield. Claude Hopkins was approached by an old friend about a new dentifrice (toothpaste) called Pepsodent.  At the time, tooth powders were peddled door to door by traveling salesmen.  Hopkins quickly declined the offer to promote this toothpaste.  It was a losing battle as less than 7% of the population in the United States had an actual toothbrush in
