A recently concluded study states that dental scans doubles or even triples the likeliness of getting tumour in outer membrane of the brain. In this manner, study suggests that procedure should be undertaken as less as possible.
Frequent exposure of dental x-rays might lead to meningioma tumour, which is more likely to hit children. Those who received dental x-ray examination at an early age of 10 years were 4.9 times more succumbed to meningioma. Meningioma, a rare but potentially debilitating type of non-cancerous brain tumour, has a probability of 22 in 10,000 to affect an individual. Growing in a lining inside the skull, slow growing tumour could prove fatal after surpassing initial stages.
Researchers examined dental histories of 1,433 patients with tumours besides 1,350 individuals free from malady. The observation was that those who were exposed to dental x-rays at some point of time in their life were more likely to develop brain tumour.
Dr. Elizabeth Claus, heading expert panel at Yale University School of Medicine, elaborated on the study stating, “Our findings suggest that dental x-rays, particularly when obtained frequently and at a young age, may be associated with an increased risk of intracranial meningioma, at least for the dosing received by our study participants.”
Subjects of the study belonged to different age groups, aged between 20 and 79, on being diagnosed with tumour. It was also observed that dental x-rays radiation doses were significantly higher in the past.
Dr. Paul Pharoah, cancer expert from Cambridge University said that people who have had dental x-rays do not need to worry about the health risks of those X-rays, but underlined the aspect that dental x-ray procedure should only be done when there is clear clinical need so that unnecessary radiation after affects can be averted.
