Preformed metal crown (stainless steel), conventional technique vs Aesthetic crown (stainless steel with composite/white veneer), conventional technique

Adverse events: bone resorption · Children with decayed primary molar teeth
1 finding from 1 review
  • Preformed crowns for decayed primary molar teeth 2015 · Cochrane All outcomes
    Six months and four years
    Bone resorption: one case at six months in a tooth treated with a veneer crown; no bone resorption at either the veneer crown or stainless steel sites at four-year follow-up (Analysis 3.2).

Hall technique vs Non-restorative caries treatment

Adverse events: gingival bleeding · Children with decayed primary molar teeth

It is very uncertain whether preformed metal crown (fitted using the Hall Technique) changes adverse events: gingival bleeding compared with non-restorative caries treatment (very low certainty).

  • Preformed crowns for decayed primary molar teeth 2015 · Cochrane All outcomes
    Six months and four years
    At six months, none (0/11) of the PMC sites had gingival bleeding, but all (11/11) veneer sites had bleeding, 10 of which bled on probing; statistically significant (McNemar's test, P < 0.001). At four years, one case…

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 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).

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).

3 findings 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).
