Silver vs non‐antibacterial

Wound healing · people with burns

Silver showed no clear difference in wound healing (number of healing events): silver xenograft vs… compared with non‐antibacterial (low certainty).

Silver diamine fluoride (SDF) vs Silver nitrate plus fluoride varnish

Caries arrest · Children and adults (with or without carious lesions)

Silver diamine fluoride (SDF) showed no clear difference in caries arrest compared with silver nitrate plus fluoride varnish (low certainty).

Silver diamine fluoride (SDF) vs Other methods (pooled: ART/glass ionomer cement, nano-silver fluoride, placebo)

Caries arrestment at the individual (patient) level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

Compared with other caries-management methods, SDF may increase caries arrestment at the individual level, but the pooled estimate is very imprecise (low certainty).

Silver diamine fluoride (SDF) vs Nano-silver fluoride (NSF; with or without green tea extract)

Caries arrestment at the surface level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

In one trial, nano-silver fluoride arrested more surfaces than SDF (OR 0.52 favoring the comparator; ungraded subgroup).

Silver diamine fluoride (SDF) vs Nano-silver fluoride (NSF; with or without green tea extract)

Caries arrestment at the individual (patient) level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

Pooling two trials, nano-silver fluoride achieved higher individual-level caries arrestment than SDF (OR 0.39 favoring the comparator; ungraded subgroup).

Silver diamine fluoride (SDF) vs Other methods (pooled: ART/glass ionomer cement, nano-silver fluoride, sodium fluoride varnish)

Caries arrestment at the tooth level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

SDF probably results in a slight increase in tooth-level caries arrestment versus other methods (moderate certainty).

Silver diamine fluoride (SDF) vs Other methods (pooled: nano-silver fluoride, sodium fluoride varnish)

Caries arrestment at the surface level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

SDF probably makes little to no difference to surface-level caries arrestment versus other methods (moderate certainty).

Silver diamine fluoride (SDF) vs Other methods (pooled: ART/glass ionomer cement, nano-silver fluoride, sodium fluoride varnish, placebo)

Adverse effects (tooth staining and other side effects) · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

SDF commonly causes black staining of arrested lesions; only mild, transient adverse events were reported, with no major adverse events (ungraded).

Silver diamine fluoride (SDF) vs Nano-silver fluoride (NSF; with or without green tea extract)

Caries arrestment at the tooth level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

Pooling two trials, SDF and nano-silver fluoride showed no significant difference in tooth-level caries arrestment (OR 1.47; ungraded subgroup).

Silver diamine fluoride (SDF; 30% or 38%) vs No treatment or another non-invasive/minimally-invasive treatment (ART, sodium fluoride or silver-based varnish, or 12% SDF)

Caries arrest · Children (age 1-10 years) with active cavitated dentin caries lesions in primary molars

SDF is effective in arresting caries progression in cavitated primary molars overall (pooled ES 0.33, 95% CI 0.26-0.40; ungraded).

1 finding from 1 review

Silver diamine fluoride (SDF >=30%, i.e. 30% or 38%), applied annually or biannually vs No treatment or another non-invasive/minimally-invasive treatment (ART, sodium fluoride or silver-based varnish, or 12% SDF)

Caries arrest · Children (age 1-10 years) with active cavitated dentin caries lesions in primary molars

The pooled caries arrest rate with SDF (>=30%, applied annually/biannually) was 51.62% (622/1205 lesions arrested) at >=12 months follow-up.

1 finding from 1 review

Silver diamine fluoride (SDF) vs Not applicable (single-arm safety outcome)

Serious adverse events · Children and older adults treated with SDF for carious lesions

No serious adverse events (e.g., allergic reactions or toxicity) were reported for SDF across the reviews (ungraded).

Silver diamine fluoride (SDF) vs Not applicable (single-arm safety outcome)

Adverse events: black staining of arrested lesions · Children and older adults treated with SDF for carious lesions

Black staining of arrested lesions was the main adverse event of SDF (reported by seven reviews); it was generally acceptable to patients (ungraded).
