BOSTON â€" A study published Tuesday in the American Cancer Society journal Cancer reported a link between certain kinds of dental X-rays and the most common brain tumor, one that is almost always benign but can still be debilitating.
The study found that people with meningioma were more than twice as likely as people without the brain tumor to have had a bitewing X-ray sometime in their life. For a bitewing X-ray, the patient holds the film in place by biting down on a tab. The study compared the self-reported dental X-ray histories of 1,433 adults who had been diagnosed with the tumor with 1,350 who had not.
Lead author Elizabeth Claus, professor at the Yale School of Public Health and a neurosurgeon at Brigham and Women’s Hospital in Boston, noted that risk factors for meningioma remain poorly understood.
