TaqI (rs731236 T>C) polymorphism in the VDR gene (C allele / variant genotype) vs CT genotype vs TT genotype (heterozygous model)

Dental caries susceptibility · Children and adults (no age limit) assessed for dental caries susceptibility

No significant association between the TaqI (rs731236 T>C) polymorphism and dental caries in Caucasians under the heterozygous (CT vs TT) model (OR 0.93, 95% CI 0.56 to 1.56); ungraded.

Laser fluorescence (DIAGNOdent 2190/pen) vs Histological validation (serial sectioning, grinding, hemisection, or microradiography)

Diagnostic accuracy for occlusal caries detection at the dentin caries detection level (D0-2 versus D3-4) · Extracted human permanent posterior teeth (premolars and molars), occlusal (pit-and-fissure) surfaces

In in vitro, laser fluorescence pen (2190) pooled specificity was 0.77 (95% CI 0.62 to 0.88) for occlusal caries at the dentin detection level; ungraded.
