TT genotype of AMELX rs17878486 vs CC genotype of AMELX rs17878486

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

No significant association between TT genotype vs CC genotype of AMELX rs17878486 and dental caries susceptibility (TT vs CC model: OR 5.12, 95% CI 0.09-278.85) in the Control group: Caries-free subgroup; certainty not graded.

Fluoride varnish vs Fissure sealant (resin-based or glass ionomer)

Caries incidence (proportion of enrolled children developing dentin caries, ICDAS 4-6) · Generally healthy children aged 6 to 9 years with at least one fully erupted first permanent molar with deep fissures or early enamel…

Fluoride varnish and fissure sealant did not differ significantly in the proportion of children developing caries at 2 to 3 years (RR 1.12, 95% CI 0.60 to 2.09; 2 RCTs; ungraded).

CT + TT genotype (T-allele carriers) of AMELX rs2106416 vs CC genotype of AMELX rs2106416

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

No significant association between CT + TT genotype (T-allele carriers) vs CC genotype of AMELX rs2106416 and dental caries susceptibility (CT + TT vs CC model: OR 0.59, 95% CI 0.15-2.31) in the Age group: Children subgroup; certainty not graded.

Tooth bleaching (carbamide or hydrogen peroxide; home and/or in-office) vs No bleaching (untreated control)

Colour change / camouflage of white spot lesions (reduction of colour disparity between carious and sound enamel) · Permanent teeth with post-orthodontic white spot lesions (orthodontic patients and in vitro enamel specimens)

Bleaching may diminish colour disparities and camouflage post-orthodontic white spot lesions, but the certainty of the evidence is very low; the findings could neither support nor refute bleaching.

Laser/light-activated bleaching vs Conventional (non-laser) bleaching with hydrogen or carbamide peroxide

Enamel microhardness / caries susceptibility · Permanent teeth / enamel specimens (in vitro)

Low-quality in vitro evidence found no support for adding lasers to in-office bleaching; laser-activated bleaching did not appear to affect enamel microhardness or caries risk versus conventional bleaching (ungraded).

One type of dental check-up (e.g. examination plus scale and polish) vs A different type of dental check-up (e.g. examination only) at the same fixed recall interval

Outcome not reported · Children and adults receiving dental check-ups in primary care, irrespective of oral disease risk

The review found no eligible studies for this question.

G allele of LTF rs1126478 vs A allele of LTF rs1126478

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

No significant association between G allele vs A allele of LTF rs1126478 and dental caries susceptibility (G vs A model: OR 0.98, 95% CI 0.87-1.10); certainty not graded.

Clinical examination with risk-based recall vs Clinical examination with 24-month recall

Periodontal disease: gingival bleeding (percentage of sites) · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with risk-based recall showed no clear difference in periodontal disease: gingival bleeding (percentage of sites) compared with clinical examination with 24-month recall (high certainty).
