Microinvasive interventions in the management of proximal caries lesions in primary and permanent teeth- systematic… 2025 All outcomesBaseline and follow-up · Multiple countries (Brazil, Saudi Arabia, Netherlands, USA, Turkey, Switzerland, Germany, New Zealand, Chile, Thailand); dental clinic/community settings
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)
Pooling 10 trials, resin infiltration reduced radiographic proximal caries progression versus non-invasive measures (OR 0.23); this subgroup was not separately GRADE-rated.

Tumour necrosis factor-alpha (TNF-α) · Humans who use e-cigarettes (mostly adults, often with periodontal disease) assessed for oral proinflammatory markers
Meta-analysis suggests no significant effect of e-cigarette use on the salivary level of Tumour necrosis factor-alpha (TNF-α) (7 studies), though heterogeneity was high (I2=95%) and the pooled estimate appears only in Figure 3E (unavailable); GCF data were limited (2 study(ies)) (ungraded).

Proposed inhibition of S. mutans adhesion to tooth surface (mechanism; direct adherence endpoint confirmed only in Ahn 2018) · Cariogenic bacteria (mainly Streptococcus mutans reference strains) and oral biofilms in vitro

Combined salivary IL-1β, IL-6, IL-8, and TNF-α levels · Humans who use e-cigarettes (mostly adults, often with periodontal disease) assessed for oral proinflammatory markers
Combining all four salivary cytokines, the meta-analysis found no effect of e-cigarette use on salivary proinflammatory marker levels (low between-marker heterogeneity, I2=31%); the pooled estimate appears only in Figure 3F (unavailable) and is ungraded.

Interleukin-1 beta (IL-1β) · Humans who use e-cigarettes (mostly adults, often with periodontal disease) assessed for oral proinflammatory markers
Meta-analysis suggests no significant effect of e-cigarette use on the salivary level of Interleukin-1 beta (IL-1β) (11 studies), though heterogeneity was high (I2=97%) and the pooled estimate appears only in Figure 3B (unavailable); GCF data were limited (2 study(ies)) (ungraded).

Enamel/dental hard-tissue changes and e-liquid cariogenic properties (demineralization, colour change, pH, sugar content, metals) · Oral bacteria (streptococci), dental hard tissue (enamel/dentin) and e-liquids studied in vitro/ex vivo (with a few clinical microbiome…
In vitro evidence suggests e-liquids are often acidic and sugar-containing and can alter enamel/dentin colour and properties, supporting a plausible cariogenic effect, but findings are heterogeneous and not pooled (ungraded, narrative).

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).

Streptococcus mutans acid (lactic acid) production and cariogenic potential · Oral biofilm of children/individuals at risk of dental caries
The review concludes that Veillonella spp. may modulate (often inhibit) S. mutans acid production and compete for lactate substrate, potentially reducing cariogenesis, but the evidence is narrative and ungraded.

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).

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).

Prevalence of white spot lesions (WSL) at debonding, subject level · Healthy adolescents and adults undergoing orthodontic treatment with fixed multi-bracket appliances
Fluoride varnish applied regularly during fixed orthodontic treatment may reduce the prevalence of white spot lesions at debonding (pooled RR 0.64, 95% CI 0.42 to 0.98), but the certainty of evidence is very low.

White spot lesion clinical score (mean values), subject level · Healthy adolescents and adults undergoing orthodontic treatment with fixed multi-bracket appliances
In a pooled analysis of two placebo-controlled trials, fluoride varnish also reduced white spot lesion clinical scores (pooled SMD -0.44, 95% CI -0.64 to -0.24); this secondary outcome was not separately GRADE-rated.
