Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

|---|---|---|
| Population | Children with active dentin cavitated caries lesions in primary molars (first and second molars) | 3168 children (age 1-10 years) with cavitated caries in primary molars across 9 RCTs (n=9) |
| Intervention | SDF applied to active dentin cavitated lesions in primary molars | 38% SDF (8 studies) or 30% SDF (1 study), applied once or repeated every 3/6/12 months (n=9) |
| Comparison | No treatment or any other non-invasive or minimally-invasive treatment | ART (3 studies); 5% NaF varnish (1); silver-based/nano-silver fluoride varnish (2); 12% SDF (1); no treatment (1); different SDF application protocols (1) |
| Outcomes | Primary: caries arrest rate, mean number of inactivated lesions, odds ratios; Secondary: patient discomfort during the treatment procedure | Caries arrest rate (all 9 studies; 5 meta-analyzed); patient discomfort/anxiety (1 study) |
| Study designs | Randomized (RCT) and non-randomized (NRSI) clinical studies | 9 randomized controlled trials; no NRSI met the inclusion criteria (n=9) |
| Timing | Follow-up longer than 6 months; no publication time restriction (last searched 10 Jan 2022) | Follow-up 6 to 36 months |

Questions and results
Silver diamine fluoride (SDF; 38% or 30%), applied at any frequency vs No treatment or another non-invasive/minimally-invasive treatment (ART, sodium fluoride or silver-based varnish, or 12% SDF)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Caries arrest Pooled across follow-up evaluations (1-36 months) SDF is effective in arresting caries progression in cavitated primary molars overall (pooled ES 0.33, 95% CI 0.26-0.40; ungraded).

Caries arrest rate (absolute proportion of lesions arrested) Follow-up >=12 months The pooled caries arrest rate with SDF (>=30%, applied annually/biannually) was 51.62% (622/1205 lesions arrested) at >=12 months follow-up. Source: Abstract; Results 3.6; Conclusions 5 · same question in other reviews | Proportion 0.5162 | 5 studies · 1205 participants | Ungraded |
SDF applied once (single application, no re-application) vs Other non/minimally-invasive treatment (ART or silver-fluoride varnish)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Caries arrest Follow-up up to 12 months (single application) · SDF application frequency: single (one-time) application A single (one-time) SDF application did not significantly arrest caries (pooled ES -0.09, 95% CI -0.48 to 0.29; ungraded). Source: Results 3.6; Figure 3b (application-frequency subgroups) · same question in other reviews | ES -0.09 [-0.48, 0.29] | 2 studies · 117 participants | Ungraded |
SDF applied biannually (every 6 months) vs Other non/minimally-invasive treatment (ART or 5% NaF varnish)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Caries arrest Follow-up up to 12 months (biannual application) · SDF application frequency: biannual (every 6 months) Biannual SDF application significantly arrested caries (pooled ES 0.39, 95% CI 0.19-0.60; ungraded). Source: Results 3.6; Figure 3b · same question in other reviews | ES 0.39 [0.19, 0.60] | 2 studies · 381 participants | Ungraded |
38% SDF (applied every 6 or 12 months) vs 12% SDF
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Caries arrest 24-30 months · SDF application frequency: variable (Fung 2018; 38% vs 12% SDF) 38% SDF arrested more caries than 12% SDF (pooled ES 0.37, 95% CI 0.27-0.47; single study; ungraded). Source: Results 3.6; Figure 3b · same question in other reviews | ES 0.37 [0.27, 0.47] | 1 study · 888 participants | Ungraded |
Silver diamine fluoride (30% SDF) vs Atraumatic restorative treatment (ART)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Patient discomfort during treatment (anxiety scale) During/after the treatment procedure One study found no significant difference in patient discomfort between SDF and ART (p = 0.15; ungraded). Source: Results 3.3 (Study Characteristics); Ref 41 (Vollu 2019) · same question in other reviews | Only one study assessed patient discomfort during treatment (SDF vs ART) using the patient's anxiety scale, obtaining almost overlapping results (p = 0.15). | 1 study · 67 participants | Ungraded |
Caries arrest Pooled across 3-12 month follow-ups · Comparator: SDF vs ART (moderator analysis by treatment type) SDF was not significantly better than ART at arresting caries (pooled ES 0.05, 95% CI -0.42 to 0.51; ungraded). Source: Results 3.6; Figure 3c · same question in other reviews | ES 0.05 [-0.42, 0.51] | 2 studies · 146 participants | Ungraded |
