Resin-based fissure sealant plus fluoride varnish vs Fluoride varnish

Changes in decayed, missing and filled (DMF) figures at whole-mouth level · Children and adolescents (general population, aged under 20 years)
1 finding from 1 review

LTF rs1126477 variant vs Reference allele/genotype

Dental caries · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

LTF rs11216477 was significantly associated with dental caries in a single study (OR 1.17, 95% CI 1.06 to 1.29; ungraded).

Quantitative light-induced fluorescence (QLF) vs Reference standard (histology, excavation, or enhanced visual examination)

Diagnostic odds ratio (DOR) for detection of early enamel caries (D1 threshold) · Asymptomatic children, adolescents, or adults presenting for clinical examination (in vivo studies), or extracted teeth of children or…

All fluorescence-based devices (red, blue, and green fluorescence combined) vs Reference standard (histology, excavation, or enhanced visual examination)

Sensitivity at fixed median specificity 0.78 (detection of early enamel caries, D1 threshold) · Asymptomatic children, adolescents, or adults presenting for clinical examination (in vivo studies), or extracted teeth of children or…

Tooth bleaching (combined in-office and home bleaching) vs No bleaching (untreated control)

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Patients with post-orthodontic white spot lesions and permanent dentition

In the single RCT, all bleached patients were satisfied with the aesthetic outcome, though the trial was at high risk of bias (ungraded).

rs1126478, additive (per-allele) model vs A allele

Dental caries · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

The additive-model association remained non-significant after excluding the adult-data study (OR 1.47, 95% CI 0.92 to 2.35; ungraded).

G allele of LTF rs1126478 vs A allele

Dental caries · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

rs1126478 showed no significant association with dental caries under an allelic model (OR 1.41, 95% CI 0.48 to 4.13; ungraded).

Bleaching vs No bleaching or alternative control

Colour disparity between carious and non-affected enamel · Permanent teeth with post-orthodontic or artificial white spot lesions

Bleaching may diminish colour disparities between carious and non-affected areas (very low certainty).

Radiographic examination (bitewing radiographs) vs Reference standard: histology

Sensitivity · Extracted molar teeth of adults with resin composite approximal restorations (in vitro; secondary root caries; Switzerland)
1 finding from 1 review
  • 2 in vitro studies (59 root surfaces) using extracted, restored teeth and a histological reference standard investigated the accuracy of radiographs. Reported estimates of sensitivity ranged from 0.40 to 0.63 and…
