Laser enamel preparation (with or without acid-etching) vs Acid-etching (phosphoric acid)

Adverse events · Caries-free children to young adults with premolars/molars requiring pit-and-fissure sealants

No adverse events were reported in any included study (ungraded, narrative).

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).

Intraglandular botulinum neurotoxin (BoNT) injection vs placebo injection

Adverse events (participants with >=1 adverse event) · Adults with Parkinson's disease and sialorrhea (drooling)

Type A botulinum toxin showed a borderline, non-significant increase in adverse events versus placebo (RD 0.10, 95% CI 0.00 to 0.21; ungraded subgroup).

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).

1 finding from 1 review

Microinvasive techniques (resin infiltration, resin/GIC sealant, or glass ionomer varnish) vs Non-invasive measures (fluoride varnish/toothpaste, flossing, oral hygiene instruction, sham/standard of care)

Adverse events and periodontal/secondary outcomes (gingival bleeding, gingival bleeding index, visible plaque index) · Children and adults with non-cavitated proximal (interproximal) caries lesions in primary and/or permanent teeth (ages 3-45)

Only three trials reported secondary/adverse outcomes; no adverse events were attributed to microinvasive treatment and periodontal findings were mixed and not pooled (ungraded).
