2. CBCT and examinations beyond routine dentistry

Cone-beam CT is not “a big bitewing”

CBCT doses are typically much higher than intra-oral or panoramic examinations. IR(ME)R still requires justification by an entitled practitioner and operators trained for CBCT. Completing Years 1–5 of this series does not by itself entitle you to take or report CBCT.

Before you use CBCT

• A clinical question that 2-D imaging cannot answer
• The smallest field of view and resolution that answer that question
• Employer entitlement and documented CBCT-specific training
• A report / clinical evaluation of the whole imaged volume — including unexpected findings in the field of view

If you refer for CBCT, you remain responsible for providing a proper clinical question. If you report, you are responsible for what is on the scan, not only the tooth you were interested in.

Other higher-dose or unusual views

Hospital medical CT, sialography or other medical exposures are outside this course. Do not copy exposure settings between machines.
