A new study suggests people who had certain kinds of dental X-rays in the past may be at an increased risk for meningioma, the most commonly diagnosed brain tumor in the U.S.
The findings cannot prove that radiation from the imaging caused the tumors, and the results are based on people who were likely exposed to higher levels of radiation during dental X-rays than most are today.
“It’s likely that the exposure association we’re seeing here is past exposure, and past exposure levels were much higher,” said Dr. Elizabeth Claus, the study’s lead author and a professor at the Yale School of Medicine in New Haven, Connecticut.
Claus and her colleagues write in the journal Cancer that dental X-rays are the most common source of exposure to ionizing radiation — which has been linked to meningiomas in the past — but most research on the connection is based on people who were exposed to atomic bombs or received radiation therapy.

There’s already a ton of research into the negative effects of diet soda, including the fact that drinking it makes you hungry, and concerns over carginogenicity. Now it turns out it can destroy your teeth.
People who drink diet soda for its sugar-free content should know that the artificial sweeteners used instead can rot tooth enamel, according to The Guardian (via Jezebel).
Sorbitol, an artificial sweetener found in diet beverages and sugar-free gum, will eat away at enamel and, according to the British Dental Journal, “ultimately cause teeth to dissolve.” Continue reading
If you believe that mercury is strictly a health hazard in the colonys – think again! (Ed.)
Ashes to ashes, dust to dust, poison to the environment. If you are cremated when you die, toxic mercury from the fillings in your teeth will pollute the air, contaminate rivers and endanger the health of those you leave behind.
Every year crematoria in Scotland belch out about 130kg of mercury, a liquid heavy metal that attacks the nervous system and can cause brain damage. But the government is planning to introduce new regulations requiring major cuts in mercury emissions. Continue reading
The American Dental Association and various state dental organizations find themselves squarely in the path of a swelling wave of litigation over tooth fillings.
The ADA, the largest and oldest dental organization in the nation, has been named in a variety of individual and class-action lawsuits in at least four states, charged with numerous transgressions including alleged fraud and negligence. Continue reading
Thousands of hepatitis C sufferers may have contracted the life-threatening virus during dental treatment, health campaigners warned yesterday.
It is feared current methods of sterilising dental equipment may not be effective in removing the risk of transmission of the virus, which is 100 times more infectious than HIV. Continue reading
LOS ANGELES (Reuters) – A coalition of public interest groups sued the American Dental Association and the California Dental Association on Tuesday, claiming they have misled the public about the dangers of mercury in tooth fillings.
The lawsuits, filed in Los Angeles Superior Court, are the latest salvo in a growing battle over mercury fillings, which opponents say can poison the body with leaking vapors possibly linked to Alzheimer’s disease and other neurological problems, especially in children and unborn babies.
