A new study on dental x-rays has revealed new information on the safety of x-rays.
A recent study has associated meningioma, a common brain tumor, with receiving dental x-rays. The ADA has reviewed the study’s findings and it has found that the study has been affected by recall bias, which means that the patients were asked to recall information about dental x-rays taken earlier in their lives. It is also noted that some of these patients were exposed to x-rays many years ago when the levels of radiation used were much higher. Precautionary measures, however, have been taken by recommending that all dentist offices use an abdominal and thyroid shield. It has also been recommended that dentists use fast developing or digital x-rays.
