Colour clinical examination (visual shade categorization: yellow, light brown, dark brown, black) vs Hardness clinical examination (tactile texture categorization: soft, medium/leathery, hard): Discriminant power for caries severity: mean difference in log10 CFU (microbial load) between lesion categories
- Population
- Patients with dentine carious lesions (deciduous/permanent teeth; children and adults)
- Intervention
- Colour clinical examination (visual shade categorization: yellow, light brown, dark brown, black)
- Comparison
- Hardness clinical examination (tactile texture categorization: soft, medium/leathery, hard)
- Outcome
- Discriminant power for caries severity: mean difference in log10 CFU (microbial load) between lesion categories
For yellow-vs-other colour compared with soft-vs-harder hardness, hardness was significantly the more discriminant test (pooled WMD -3.87, 95% CI -4.46 to -2.87; 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.
