Interleukin-8 (IL-8) · 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-8 (IL-8) (6 studies), though heterogeneity was high (I2=84%) and the pooled estimate appears only in Figure 3C (unavailable); GCF data were limited (1 study(ies)) (ungraded).

DMFT/DMFS index (dental caries experience) · Humans who use e-cigarettes (adolescents to adults) assessed for dental caries
A meta-analysis of 3 studies compared DMFT/DMFS in e-cigarette users vs non-smokers, but the pooled effect appears only in Figure 3A (unavailable) and heterogeneity was very high (I2=98%); the effect of vaping on dental caries remains unclear (ungraded).

Interleukin-6 (IL-6) · 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-6 (IL-6) (6 studies), though heterogeneity was high (I2=95%) and the pooled estimate appears only in Figure 3D (unavailable); GCF data were limited (1 study(ies)) (ungraded).

Dry mouth (xerostomia) · Humans who use e-cigarettes (adolescents to adults) assessed for dental caries
Two studies reported more frequent xerostomia (dry mouth) among e-cigarette users than non-smokers, which may raise caries risk, but results were not pooled (ungraded, narrative).

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).

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.

Untreated dental caries and caries risk · Humans who use e-cigarettes (adolescents to adults) assessed for dental caries
Across individual cross-sectional studies, e-cigarette users tended to have more untreated caries and higher caries risk than non-smokers (per-study OR ~2.0-4.2), but results were not pooled (ungraded, narrative).

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).
