Study links dental x-rays, brain tumors
By Fiza Hashmi | April 11, 2012Many who await dentist appointments with a feeling of trepidation may do so with good reason. A study published yesterday in American Cancer Society found frequent dental X-rays may be linked to meningioma, an often benign but sometimes harmful brain tumor. Study participants who remembered having bitewing X-rays before age 10, a procedure used to reveal tooth decay in the upper and lower teeth by determining bone density changes caused by gum disease, were twice as likely to have meningioma, according to the study.
