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: effect size (f) for microbial load (log10 CFU) between lesion categories · Patients with dentine carious lesions (deciduous/permanent teeth; children and adults)

The weighted effect size favoured hardness (f=2.62) over colour (f=0.46) for discriminating microbial load, supporting hardness as the more reliable examination (ungraded).

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 · Patients with dentine carious lesions (deciduous/permanent teeth; children and adults)

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).
