There are many cases of death occurring in dental offices over the years for both children and adults having dental procedures. The Dallas Morning News made an in depth piece exploring various issues surrounding death in the dental chair and the story indicated cover-up and not holding offenders accountable. The seven part piece was published in 2015 and is available at http://interactives.dallasnews.com/2015/deadly-dentistry/index.html. It is a lengthy investigative piece, so you will need a fair amount of time to get through the entire story. For convience the links for each of the seven parts are also provided separately below.

What to Do In Case of a Dental Emergency

by

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 … Read more

Prefabricated blood vessels may revolutionize root canals

by

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 … Read more

Tooth repair could occur using Alzheimer’s drug

by

The renewal of living stem cells in tooth pulp could occur using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London. Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and seals the tooth pulp, but is insufficient to effectively repair large cavities. Currently dentists use human-made cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning the normal mineral level of the tooth is never completely restored. In a paper published in Scientific Reports, scientists from King’s College London have proven a way to stimulate stem cells contained in the … Read more

Does the Sound of the Toothbrush Brushing Effect Quality?

by

A group  of researchers in Japan have discovered that how effectively we clean our teeth and how satisfied we are with quality of the brushing depends on the sound of the bristles scrubbing against the enamel.  The team used a tiny microphone in a modified toothbrush to ‘sample’ the sound being made in the mouth during brushing and to modulate it and then feed that sound back to a group of volunteers via headphones to see what effect the sound has on cleaning efficacy and satisfaction. The team found that if they manipulated the pitch, or loudness and frequency, of the brushing sound they could change the volunteers’ perception of comfort experienced and accomplishment of brushing. It was also demonstrated that if they gradually increased the frequency as teeth cleaning progressed, the volunteers felt like the process was more comfortable and at the end of … Read more
