Correct answer: B — Periapical radiograph using the paralleling technique
The correct answer is B. Periapical radiographs taken using the paralleling (long-cone) technique are the gold standard for assessing periapical status—apical bone loss, root resorption, and periapical pathosis. UK guidance (SDCEP, NHS hospital referral criteria) explicitly recommends this technique for anterior teeth to provide optimal detail of the root apex region with minimal distortion and magnification. Option D (panoramic) lacks apical resolution and is reserved for overview imaging and generalised assessment. Option E (occlusal) shows arch morphology but not periapical detail. Option C (cephalometric) is for skeletal/orthodontic assessment, not periapical diagnosis. Option A (bitewing) visualises interproximal caries and proximal bone levels but inadequately demonstrates the apical region.
