Correct answer: D — Cone Beam Computed Tomography
CBCT stands for Cone Beam Computed Tomography. It is the established standard three-dimensional radiographic imaging technique in dental and maxillofacial radiology, first introduced in the late 1990s and now widely adopted across all dental specialties in UK and international practice. The distractors—whilst using plausible technical dental or medical terminology—do not represent recognised acronyms or procedures in dental imaging. Option E creates confusion with bone anatomy terminology; option C misappropriates the real term 'cephalometric'; option B references a prosthetic procedure unrelated to radiology; and option A conflates the radiography term 'bite-wing' with an incorrect expansion. A candidate familiar with UK dental practice, SDCEP guidance, and radiology literature will readily identify the correct answer.
