Diet High in Fish and Nuts Can Protect Against Gum Disease
High consumption of polyunsaturated fatty acids, such as those found in nuts and fatty fish, has been shown in a study to lower the risks of gum disease and periodontitis.
Durinjg a five-year study of 184 adults, those who ate the hightest amounts of fatty acids were 30 percent less likely to develop gum disease and 20 percent less likely to develop periodontitis.
"This study show that a small and relatively easy change in peoples's diet can massively improve the condition of their overall well-being," said Nigel Carter, DDS, chief executive of the British dental Health Foundation.
"Most people suffer from gum disease at some point in their life," said Carter. "What people tend not to realize is that it can actually lead to tooth loss ifr left untreated, and in this day and age, most people should be able to keep all their teeth for life."
Dental X-rays and brain tumor risk(Ada.org)
A recent study published in Cancer, a scientific journal of the American Cancer Society, associates yearly or more frequent dental X-rays with an increased risk of developing meningioma, the most commonly diagnosed brain tumor in the United States.
The study included 1,433 patients with a diagnosis of intracranial meningioma and a control group of 1,350 individuals. Study participants self-reported having had bitewing, full-mouth, and/or panorex dental X-rays.
Results showed that over a lifetime patients with meningioma were more than twice as likely as controls to report having ever had bitewing X-rays. Individuals who reported having panorex X-rays yearly or more frequently at ages less than 10 years had a nearly 5 times greater occurrence of meningioma.
A neurosurgeon and lead author of the study, Dr. Elizabeth Claus, stated in an interview with CBS News, "This research suggests that although dental X-rays are an important tool in maintaining good oral health, efforts to moderate exposure to this form of imaging may be of benefit to some patients."
The ADA Division of Science has carefully reviewed the study and notes some weaknesses in the study design and interpretation of the results:
Considering these weaknesses and the small size of the reported effect, this study shouldn't raise significant concerns. However, it's a good reminder that dental X-rays should be taken only when the dentist expects the diagnostic yield to affect patient care.
The ADA's long-standing position is that dentists should order dental X-rays for patients after a clinical exam when necessary for diagnosis and treatment, and not for screening purposes.
Because of widespread media coverage on the study, your patients may have questions about the study and the safety of dental X-rays. Below are some potential questions and talking points.
I heard on the news that dental X-rays can cause brain tumors. Is that true?
What precautions do dentists take to reduce the radiation risks of dental X-rays?
I am worried about having dental X-rays. What are the benefits?
FDA Warns Spinbrushes Can Be Choking Hazard
The U.S. Food and Drug Administration has issued a warning to parents, caregivers, consumers and dental care professionals about reports of serious injuries and potential hazards associated with the use of all models of the Spinbrush--specifically the Arm & Hammer or Crest Spinbrush.
While turned on, the brush head has come off in the user's mouth or near the face, causing cuts to the mouth and gums, chipped or broken teeth, swallowing and choking on the broken pieces, or injuries to the face and eyes, according to the FDA's warning.

Dr. Zieve highly recomends the RotaDent Plus tooth brush.
