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 (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).

Reported narratively by 3 trials (Arthur 2018, Sarti 2020, Jorge 2019). No adverse events were attributed to microinvasive treatment. Gingival bleeding index: no significant difference in Arthur 2018 and Jorge 2019 but…

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).
