How do everyday background (natural), dental equipment, and medical equipment radiation levels compare?
First, it is important to remember tha
~ X-rays are an established and essential part of every dental practice.
~ A CBCT scan provides dentists with views that were previously unavailable other than through medical CT.
~ CBCT offers views of patient anatomy in three dimensions, without the magnification, distortion, and superimposition.
~ The precision of CBCT scans assists in precise diagnosis and treatment plans with the goal of better clinical outcomes.
~ The effective dose from a standard CBCT scan is at least 10 times less radiation than that from a medical CT of the skull used for dental purposes.
It is also important to note that clinicians make the decision on when a case warrants a CBCT scan and on what settings to use for the specific patient’s needs, based on their clinical expertise and ALARA principles.
CBCT technology exposes patients to a lower radiation dose than a number of other imaging modalities and far less than medical CT. The following tables provide dose comparisons for natural and medical radiation exposures.
