The Dental Apron is designed to protect patients and clinicians from exposure to radiation during routine dental x-ray imaging. The ultimate goal of the dental apron is to stop every bit of radiation from reaching the patient or clinician, but an extra layer of defense doesn’t hurt either. Dental aprons are usually filled with lead or other similar material capable of stopping radiation from passing through to reach the patient or clinician.”’ aprons protect patients and clinicians from exposure to radiation during routine dental x-ray imaging. These aprons are heavy because they are filled with lead or similar material capable of stopping radiation from passing through to reach the patient or clinician. This helps reduce the amount of radiation exposure for both the patient and the dentists, who will often remain in the same room while taking x-rays.
