E-cigarette aerosol / e-liquid exposure (flavored and unflavored; nicotine and non-nicotine) vs Unexposed controls / unflavored e-liquid / conventional cigarette smoke

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).

Stevia (high-intensity/non-nutritive sweetener) in a daily snack vs Baseline (within-group change); white sugar snack is a parallel arm with no between-group effect size reported

Change in Mutans streptococci (MS) and Lactobacilli in saliva · Schoolchildren (6-9 years), high caries risk

The single stevia trial (Cocco 2019) reported a significant reduction in salivary Mutans streptococci and lactobacilli, but gave no effect size and was not GRADE-rated.
