Glass ionomer (modified glass ionomer varnish) vs Non-invasive measures (standard of care)

Radiographic proximal caries lesion progression · Children with non-cavitated proximal caries lesions in primary teeth (ages 5-8)

In one trial, glass ionomer varnish showed no statistically significant difference versus non-invasive care in radiographic proximal caries progression (OR 0.58, CI includes 1; ungraded subgroup).

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).

Resin infiltration vs Non-invasive measures (fluoride varnish/toothpaste, flossing, oral hygiene instruction, sham/standard of care)

Radiographic proximal caries lesion progression · Children and adults with non-cavitated proximal (interproximal) caries lesions in primary and/or permanent teeth (ages 3-45)

Pooling 10 trials, resin infiltration reduced radiographic proximal caries progression versus non-invasive measures (OR 0.23); this subgroup was not separately GRADE-rated.

Microinvasive techniques (resin infiltration, resin/GIC sealant, or glass ionomer varnish) vs Conventional restoration

Radiographic proximal caries lesion progression · Children and adults with non-cavitated proximal (interproximal) caries lesions in primary and/or permanent teeth (ages 3-45)

No eligible studies compared microinvasive techniques with invasive (restorative) treatment; this planned comparison had zero included studies.

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

Radiographic proximal caries lesion progression · Children with non-cavitated proximal caries lesions in primary teeth (ages 3-9)

In primary teeth (5 trials), microinvasive techniques reduced radiographic proximal caries progression versus non-invasive measures (OR 0.38; ungraded subgroup).

Microinvasive techniques (mostly resin infiltration; incl. resin sealant) vs Non-invasive measures (fluoride varnish/toothpaste, flossing, oral hygiene instruction, sham/standard of care)

Radiographic proximal caries lesion progression · Children and adults with non-cavitated proximal caries lesions in permanent teeth (ages 11-45)

In permanent teeth (7 trials), microinvasive techniques reduced radiographic proximal caries progression versus non-invasive measures (OR 0.18; ungraded subgroup).

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)

Radiographic proximal caries lesion progression · Children and adults with non-cavitated proximal (interproximal) caries lesions in primary and/or permanent teeth (ages 3-45)

Microinvasive techniques probably reduce radiographic progression of non-cavitated proximal caries lesions compared with non-invasive measures (moderate certainty).

Physiotherapy (tongue-spatula jaw exercises) vs No active treatment (control)

Maximal mouth opening (interincisal distance) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

It is very uncertain whether physiotherapy (tongue-spatula jaw exercises) changes maximal mouth opening (interincisal distance) compared with no active treatment (very low certainty).
