Currently, no evidence has shown that the mercury released from fillings has any harmful effects on health. MRI scanners can cause heating of amalgam which causes mercury vapour to be leaked. There has not been any previous research published that indicate the lower power scanners cause a release of mercury from fillings. The higher powered MRI scanners are generally used only for research and clinical trial purposes.
The investigation indicated that the incidents had been caused by health professionals giving patients who should have liquidised food a ‘soft food’ diet. To overcome this experts are calling for an end to the term ‘soft diet’ to prevent further harm to patients.
