Another Reason to Brush

There have been so many studies on Alzheimer’s Disease.   Causes? Cure?  This disease causes brain changes that gradually get worse. It’s the most common cause of dementia. In Alzheimer’s disease, brain cells degenerate and die, causing a decline in memory and mental function.  Some days I am sure this is why I can’t find my cell phone!  A recent study correlates daily brushing with dementia.  The article below was posted by, and while the study doesn’t seem definitive, it points strongly towards the benefits of brushing.   Hoolulu Denist

Daily Brushing Associated with Lower Risk of Dementia

The Journal of American Geriatrics has released a study claiming that daily brushing is associated with a lower chance of developing dementia late in life. The study observed 5,468 people over a period of 18 years. All participants in the study resided at a retirement community in Southern California.Senior Center

Of the 5,468 studied, 1,145 developed some form of dementia and those who developed dementia were much less likely to brush daily and maintain good oral health habits. Richardson, a spokesperson for TeethCenter said, “This report leaves plenty of room for interpretation. I think it’s safe to say that the adults that exercised healthy oral health habits had a lower case of developing dementia, but, why is that the case?”

Researchers on the study warned that the study “did not prove a cause and effect between oral health and dementia”. It has been long suggested that oral health is directly related to overall health as people who care for their teeth tend to care for their bodies, but, the direct correlation and causation is still unclear.

In my Honolulu dental practice, we really focus on preventative care.  Good oral home care is the cornerstone of good oral health and should be supplemented with regular exams and cleanings.   It makes sense that all of our bodies systems are connected, and oral health is connected to overall health.  As a dentist, I know this is a fact.   We are learning, more and more.  Someday we will have all the answers… but until then, I’ll just brush at least twice a day… unless I forget.


Mouthpieces Improve Athletic Performance

The Hawaii Midweek – October 24 issue had a huge feature article on our Hawaii boys playing for the Oregon Ducks- particularly Marcus Mariota, the Ducks’ starting freshman quarterback!  Looks like the UH Warriors missed out by not snatching him up this year.. auwe, what were we thinking?  While I am not a consistent football follower, some things make you sit up and take notice.  Marcus is definitely one to watch.

Of course, as a Honolulu Dentist, I tend instead to follow everything related to oral health.   This is probably weird, but while thinking about football, I am thinking about custom fitted mouthpieces! Mostly as a way to protect our athletes, and their healthy teeth and beautiful smiles…. but did you know that fitted mouthpieces can actually improve performance??  Honolulu Dentist

The use of mouthguards and sports have been documented since the 1800’s when a London dentist fitted boxers teeth with strips of resin.  Dental and head injuries have increased in sports such as football, boxing, and hockey to the point that some professional to high school athletic teams have mandated the use of mouthguards in attempts to reduce these injuries.  The 2008-2009 National Collegiate Athletic Association Sports Medicine handbook mandates the use of mouthguards during football, women’s field hockey,  ice hockey and men’s lacrosse.

The American Dental Association’s Council on Access, Prevention and Interprofessional Relations and Coouncil on Scientific affairs concluded that mouth guards provide a protective effect against hard-tissue or soft tissue damage in the mouth.  Injuries such as tooth fractures, lip lacerations and mandibular damage were impacted.   Honolulu Dentist

A recent trend however, is the increased use of mouth pieces for improved performance.  In the 1970-1980’s reports of improvement of muscular strength, endurance, and increased ability to train harder and recover from an injury at a faster rate with a mouthpiece, vs without a mouthpiece.  This older research however was deemed unreliable because of the possibility of a placebo effect.  

Recent research, conducted by Dena P. Garner, PhD; Wesley D. Dudgeon, PhD, Timothy P. Scheett, PhD, and Erical J. McDivitt, MS, The purpose of their study was to determine if use of a mouthpiece would alter the cortisol levels during training, and thus begin to explain the improved performance that mouthpiece users have been experiencing. They found that custom fitted mouthpieces resulted in a significant difference in Cortisol levels.  Reducing levels of cortisol is ideal for an athlete to achieve tissue growth and positive adaptations to exercise training.

It seems that one factor required to improve results is to ensure a well fitting mouthpiece.  The researchers reported that a 1991study  (Francis and Brasher) showed a decrease in voluntary oxygen consumption, instead of the increases that they found in their recent study.  They attributed it to the use of well -fitting mouthpieces that did not create any obstruction in breathing.   Honolulu dentist
