Cancer researchers might have hit upon a link between the most common form of brain cancer, the meningioma, and a certain type of dental X-Ray. Researchers have found that people diagnosed with meningiomas are twice as likely to have undergone so-called bitewing X-rays — the kind that tend to hurts alot when the dentist makes you bite down on a hard, pointy piece of cardboard with your molars.
Many studies have already linked the ionization energy of radiation emanated from atomic bombs and radiation therapy to this particular form of brain cancer but the current study whose lead author Dr. Elizabeth Claus from Yale School of Medicine in New Haven, Connecticut states that dental X-rays are the most common source of exposure to such radiation which has also been shown by many other studies conducted on the effects of dental X-rays.
1,433 people in Connecticut and the San Francisco Bay who had been diagnosed with Intracranial Meningioma between May 2006 and April 2011 were compared with 1,350 tumour-free individuals similar in sex and geographic location. As a result it was found out that people diagnosed with tumours were twice as likely to report having received a bite-wing X-ray.
In the wake of this research, Dr. Alan Lurie, president of the American Academy of Oral and Maxillofacial Radiology has advised patients to be careful about receiving dental X-rays and ask their doctors as to why is it important to have their skull pumped with this harmful ionizing radiation. Such X-rays should be avoided at all costs and only be performed in dire necessity.
