‘Dental X-rays are essential for detecting serious oral and systemic health problems, and generally the amount of radiation is very low. But new thinking on dental X-rays is that the "one size fits all" schedule is outdated.
All dentists should follow the ALARA principle (as low as reasonably achievable) when determining what X-rays to order. Adhering to this principle will minimize the patient's radiation exposure. Whenever any kind of dental X-ray is done, patients should wear protective lead aprons with thyroid collars.
The aprons do not shield us from internal radiation "scattering," especially with sensitive tissue like the thyroid gland. That's why it's important to reduce the X-ray beam to the smallest size that provides necessary information…
