Radiation Exposure from Dental X-rays
What is the Radiation Dose relative to Dental X-rays?
X-rays are an established and essential part of every clinical practice. Gendex imaging solutions provide clinical benefits while supporting the ALARA principle on the use of radiography. Specifically:
- Dental X-rays provide valuable information that allow a clinician to better evaluate what is happening beneath the surface of your teeth and gums.
- Dental X-rays assist in precise diagnosis and treatment plans with the goal of better clinical outcomes.
It is the dentist that will make a decision, based upon clinical evaluation, as to whether dental X-rays are warranted and consistent
with ALARA principles. Here are the detailed ADA Recommendations.
Here are some data points about radiation doses relative to some common dental x-rays. Note that intraoral sensors do not emit radiation (the source of the radiation is from the X-ray generator). Digital intraoral sensors require less radiation dose than traditional film to produce an image. Gendex dental X-ray solutions are uniquely designed to enable the dentist to further reduce radiation dose thus exposing the patient to less radiation than other digital sensors.
Relative radiation doses:
– A digital sensor BW/PA is 0.004 – 0.006 mSv (50 – 75% less than equivalent film image) 1
– A D-speed film BW/PA is 0.017 mSv1
– A digital pan is 0.020 mSv and a digital ceph is 0.007 mSv2
– A 3D SFOV standard resolution, low dose 4x6 scan range from ~ 0.017 to 0.035 mSv2
– A GXCB-500 HD 8x8 scan is 0.053 mSv
– A flight from London to Los Angeles is 0.080 mSv3
