Preformed crown (any material; conventional technique or Hall Technique) vs Filling (any material; with or without complete carious tissue excavation; with or without pulp treatment)

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

Preformed crown (any material; conventional technique or Hall… showed no clear difference in adverse events: gingival bleeding compared with filling (any material; with or without complete carious tissue…; GRADE not reported.

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).

    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…

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).
