Question · asked by 1 review
Radiographic caries detection (bitewing radiography) vs Reference standard (histological validation or cavity/lesion opening; advanced = cavitated/dentin-involved lesions, all = enamel-confined initial lesions also counted): PPV for detecting advanced occlusal caries
- Population
- Occlusal surfaces of permanent molars (demonstrated in 12-14 year-olds; underlying diagnostic accuracy studies, mostly in vitro)
- Intervention
- Radiographic caries detection (bitewing radiography)
- Comparison
- Reference standard (histological validation or cavity/lesion opening; advanced = cavitated/dentin-involved lesions, all = enamel-confined initial lesions also counted)
- Outcome
- PPV for detecting advanced occlusal caries
In the Egyptian public health clinic setting, the positive predictive value of radiographic detection for advanced occlusal caries was 58.3% at an assumed prevalence of 19.0% (ungraded).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
