Researchers have stated that the risk of non-malignant brain tumors can rise with frequent dental X-rays.
The study has stated that chances of having meningioma tumors can be doubled and even tripled over a lifetime by having dental X-rays. The brain is covered by an outer membrane and the tumors can grow there. The risk is five times among children.
But it was added that brain tumor is not likely to develop and the chances are minute for the same. Every year about two to three people out of 100,000 people in the UK are affected by meningiomas.
These tumors grow very slowly and are usually benign and have no symptoms also.
A comparison was made between people who had meningioma tumors and those who did not have these tumors and it was seen that people who were exposed to X-rays were more likely to have these tumors.
Lead author Elizabeth Claus, a professor at Yale and a neurosurgeon at Brigham and Women's Hospital in Boston said, “The study highlights the need for increasing awareness regarding the optimal use of dental X-rays , which unlike many risk factors, is modifiable.”
