Past dental X-rays could have lead to an increased chance of a patient developing a brain tumour, according to a new report.
A joint investigation by researchers at Brigham and Women's Hospital (BWH), Yale University School of Medicine, Duke University, UCSF and Baylor College of Medicine has found that those patients who developed meningioma between May 2006 and April 2010 were twice as likely to have had been exposed to radiation during a dental procedure known as a bitewing exam.
These risks further increased when patients were exposed to more frequent examinations.
"The findings suggest that dental X-rays obtained in the past at increased frequently and at a young age, may be associated with increased risk of developing this common type of brain tumour," said Elizabeth Claus, a neurosurgeon at BWH and Yale University School of Medicine at New Haven.
The scientist pointed out that the dental X-rays currently in use have much lower dosages of radiation.
