Sample itemWhat is the principal use of a periapical dental radiograph?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Assess entire tooth root and periapical bone
Periapical radiographs show the full tooth root and surrounding apical bone, supporting assessment of endodontic disease, trauma, and root morphology.
Option by option
A. Measure facial symmetry
Facial symmetry needs other assessment.
B. Screen both jaws for every tumour
Panoramic imaging gives broader jaw overview.
C. Assess entire tooth root and periapical bone (correct)
Correct: periapical view includes root apex and adjacent bone.
D. Assess middle-ear ossicles
Ossicles require temporal-bone imaging.
