Cracked Tooth?

New Research Study May Help With Treatment


I see cracked teeth all the time. Research suggests that the majority of adults have at least one posterior (molar or premolar) cracked tooth. Crack progression and related symptoms are a common concern in everyday dental practice.

I have therefore decided to renew my participation in the National Dental Practice Based Research Network (PBRN). The National Dental PBRN is a network of dental practices committed to advancing knowledge by conducting research in their practices. The current study we are participating in is the Cracked Tooth Registry Study. This study may help to determine not only the characteristics of cracked teeth but most importantly how to treat them.

You may be eligible to participate in the Cracked Tooth Registry Study if:

  1. You are an adult between the ages of 19-85
  2. You have a cracked posterior tooth (premolar or molar).
  3. You will remain in the geographic area for the next 4 years.
  4. We may contact you over the next 4 years.

To learn more about the PBRN, please visit: You may also be compensated for your participation in this study.

Please feel free to contact me or the staff at my office, Dr. Laurence Stone in Doylestown, PA with any questions or concerns or to schedule your next visit so we can talk more about this. We will be checking out those teeth next time for any cracks!

Alzheimer’s and Dental Health


Cognitive decline, including Alzheimer’s disease, is a major concern of the aging population in America. It may now even be the third leading cause of death in America behind only cardiovascular disease and cancer. Although reporting numbers vary, it is safe to say that as of 2014, Alzheimer’s affects approximately 5.2 million Americans and 36 million people globally. Up until recently all of the research to prevent and treat this disease has been focused on identifying a single pathogenic target, and no single drug has been shown to stop or even slow the progression of Alzheimer’s. But this may be about to change.

In a small study by Dr. Dale E. Bredesen at the UCLA Mary S. Easton Center for Alzheimer’s Disease Research along with the Buck Institute for Research on Aging, it was found that using a complex, 36 point therapeutic program that involves comprehensive diet changes, brain stimulation, exercise, sleep optimization, specific pharmaceuticals and vitamins, as well as additional steps affecting brain chemistry, significant improvement in cognitive function has been achieved. (See Bredesen, Dale E., Reversal of Cognitive Decline: A Novel Therapeutic Program, Aging, Sept 2014, Vol.6 N9).

So what’s all this got to do with dentistry you ask? Well, one of the therapies involved in treating dementia with this protocol is reducing the amount of inflammation in the body. Inflammation was found to be a comorbidity in this study. And for those of us with teeth, it has long been known that infection in the gums contributes greatly to the total amount of inflammation in the body, exacerbating other systemic problems like diabetes. Ergo, healthier gums = reduced inflammation = better brain function.

Nine of the 10 people in this study showed significant cognitive improvement following Dr. Bredesen’s protocol. On a personal note, having watched my mother succumb to dementia in her later years, I was glad to see that dental health was recognized in this study as playing a vital role in contributing to cognitive health.

If you have any questions we can help with relating to reducing inflammation in your mouth, feel free to contact me or the staff at my office, Dr. Laurence Stone in Doylestown, PA with any questions or concerns or to schedule your next visit so we can talk more about this. Remember, brushing two minutes twice a day with fluoride toothpaste and flossing daily are important ways to take care of your dental health.
