Provide a PICO-style example evaluating a digital radiography decision-support tool in dentistry.

• A. Population: adults needing dental radiographs; Intervention: AI-powered decision-support; Comparison: standard imaging guidelines; Outcome: improved diagnostic accuracy and reduced radiation exposure
• B. Population: adults needing dental radiographs; Intervention: standard imaging guidelines; Comparison: AI-powered decision-support; Outcome: improved diagnostic accuracy and reduced radiation exposure
• C. Population: children; Intervention: AI-powered decision-support; Comparison: standard imaging; Outcome: reduced radiation
• D. Population: adults; Intervention: AI against CT imaging; Comparison: no imaging; Outcome: better

Answer: (A)

This item tests how to frame a clinical question in PICO for evaluating a digital radiography decision-support tool in dentistry. The best framing clearly defines who you’re studying, what you’re testing, what you compare it against, and what outcomes you care about. In this option, the population is adults who need dental radiographs, which matches the typical adult dental imaging population. The intervention is an AI-powered decision-support system, the technology you want to evaluate. The comparison is standard imaging guidelines, representing the usual approach against which the new tool would be judged. The outcome combines a meaningful clinical measure—improved diagnostic accuracy—with a patient-safety/quality measure—reduced radiation exposure. This makes the question both clinically relevant and measurable, aligning the tool’s intended use with real-world practice and patient safety. Why the other framings are less suitable: one option swaps the intervention and comparison, which muddies what’s being tested and makes the question harder to interpret in a standard PICO sense. Another option limits the population to children and ties the outcome only to radiation reduction, omitting diagnostic performance and applicability to typical adult dental care. A final option compares AI to CT imaging with no imaging as the baseline, which shifts away from evaluating a dental radiography decision-support tool within its usual radiographic modality and patient population.
