SDF plus potassium iodide vs Split into two contrasts: (1) TCS paste (arrest 100%); (2) CPP-ACP (arrest 100%); SDF+KI arrest 54.8% at 24 months, p<.001

Caries arrest · Patients with early enamel carious lesions on permanent molars

SDF plus potassium iodide arrested 54.8% of early enamel lesions at 24 months; no pooled estimate or GRADE rating was reported.

38% SDF + potassium iodide solution (applied annually) vs Tricalcium silicate (TCS) paste (applied twice daily)

Remineralization/arrest of early enamel carious lesions · Patients with early enamel carious lesions on permanent molars

For early enamel lesions, annual SDF+KI was significantly LESS effective than twice-daily tricalcium silicate paste (54.8% vs 100% arrested; p<0.001; ungraded).

Resin sealant (one-time) vs Control (water)

New coronal caries in permanent molars (caries prevention) · Children with dental caries in permanent (first) molars

Resin sealant gave a 65% prevented fraction (fissure site) vs water, the highest fissure-site value (p<0.002; ungraded).

38% SDF plus oral health education vs oral health instruction plus water

new root-surface carious lesions or restorations · community-dwelling older adults with root caries

SDF plus oral health education had a 33% preventative fraction at 24 months; no pooled estimate or GRADE rating was reported.

38% SDF + potassium iodide solution (applied annually) vs CPP-ACP

Remineralization/arrest of early enamel carious lesions · Patients with early enamel carious lesions on permanent molars

For early enamel lesions, annual SDF+KI was significantly less effective than twice-daily CPP-ACP (54.8% vs 100% arrested; p<0.001; ungraded).

1 finding from 1 review

38% SDF varnish plus oral health instruction vs oral health instruction plus water

new root-surface carious lesions or restorations · Older adults with root caries in permanent (mature) teeth (mean age 75 years)

1 finding from 1 review

Sodium fluoride (NaF) varnish, applied every 3 months, plus OHI vs inactive control

Root carious lesions prevention · Older adults with root caries (community-dwelling or residential elders)

In elders, sodium fluoride varnish gave a 64% prevented fraction for root caries vs water, lower than SDF (71%) (p<0.01; ungraded).

1 finding from 1 review

38% SDF (every 6 months) vs no treatment

Inactive (arrested) carious lesions on permanent first molars · Children with dental caries in permanent (first) molars

Prior SDF application without a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Glass-ionomer cement bonded to caries-affected dentin (in vitro)

SDF pretreatment without a rinsing step does not affect glass-ionomer cement bond strength to caries-affected dentin (MD 0.26 MPa, 95% CI -0.30 to 0.82; ungraded).

1 finding from 1 review

Prior SDF application without a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Dental adhesives bonded to sound dentin (in vitro)

Prior SDF without a rinsing step significantly reduces adhesive bond strength to sound dentin (MD 17.52 MPa favoring untreated dentin, 95% CI 5.81 to 29.22; ungraded).
