Study links dental X-rays and common brain tumor

Regular dental care is a normal part of life of most people in Maryland. While some procedures are significant enough that we might suffer a personal injury from medical malpractice, we tend not to anticipate problems from the common preventive practices. They can happen, though, and victims of such negligence have a right to pursue action to be sure they get the necessary medical care and compensation.

There is a new study out today from the American Cancer Society that is prompting new concern over one very common form of dental practice. The report appearing in the organization's journal "Cancer" indicates a link between some types of dental X-rays and meningioma, the most common form of brain tumor.

While such tumors are rarely malignant, they can grow to a significant size and create pressures that can lead to headaches, vision issues and loss of speech or motor control.

According to the findings, people who have had a bitewing X-ray sometime in their life doubled their chances of developing meningioma compared to people who have not had such an X-ray. It also found that those who underwent the more rarely used panorex X-ray were about three times more likely to suffer from meningioma than those who had never had that kind of X-ray.

The data was collected by capturing the self-reported dental X-ray histories of nearly 2,800 adults. All of their reported exposures to X-rays took place in the 1960s. Of the total pool, 1,433 adults had eventually been diagnosed with meningioma. The remaining 1,350 had not.

The conclusion from researchers is that ionizing radiation was the likely factor causing meningioma. And it so happens that the greatest source of artificial ionizing radiation exposure in the United States is through dental X-rays.

Dentists are urged to use X-rays judiciously. American Dental Association recommendations for the average patient suggest about one X-ray every one to two years for children; every 18 to 36 months for adolescents; and every two to three years for adults.

The ADA casts a shadow on the results by noting that they are based on memories which may be faulty. They also note that radiation exposure has been reduced over the years as technology has improved.

The author of the study agrees the findings don't warrant alarm. But she says they suggest patients should talk to their dentists about the findings.

I seldom leave remarks, however i did some searching and wound up here Study links dental X-rays and common brain tumor | Montgomery County Personal Injury Attorney Blog.
And I actually do have a couple of questions for you if it's allright. Is it just me or does it give the impression like some of the comments look like they are left by brain dead visitors? :-P And, if you are writing on other online sites, I would like to keep up with anything fresh you have to post. Could you make a list of every one of all your public sites like your twitter feed, Facebook page or linkedin profile?
