Laser fluorescence (DIAGNOdent 2095) vs Histological validation (serial sectioning, grinding, hemisection, or microradiography)

Diagnostic accuracy for occlusal caries detection at the caries detection level (D0 versus D1-D4) · Extracted human permanent posterior teeth (premolars and molars), occlusal (pit-and-fissure) surfaces

In in vitro, laser fluorescence (DIAGNOdent 2095) pooled summary ROC AUC was 0.81 for occlusal caries at the caries detection level; ungraded.
