Correlation between e-cigarette use and salivary flow rate, pH, and buffering capacity: a cross-sectional pilot study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe prevalence of e-cigarette use has increased rapidly among youth and adults, partly owing to its advertising as a safer smoking cessation aid. In this cross-sectional pilot study, we aimed to explore the effects of e-smoking, including e-cigarette smoking and nonsmoking, on salivary flow rate, pH, buffering capacity, and salivary consistency.
methodsParticipants aged 18–45 years at the Dental University Hospital who were healthy and with no systemic or salivary gland diseases were included. Saliva samples were collected and analysed using the Saliva-Check Buffer test. Twenty e-smokers and nineteen nonsmokers were recruited as the comparison groups.
resultsAll vapers had low resting saliva (χ² = 16.467, p = 0.000), with higher rates of low buffering capacity (36.8% vs. 1.2%, p = 0.000) and acidic pH (92.9% vs. 7.1%, p = 0.000). Vapers also had reduced saliva flow and altered saliva texture (p = 0.000). These findings indicate that vaping is associated with reduced saliva production, decreased buffering capacity, increased oral acidity, and altered saliva texture.
conclusionsThe study results show that e-cigarettes have a direct effect on saliva. Saliva check kits can serve as educational tools in clinics to help dentists advise and educate e-cigarette smokers about the oral health effects of e-smoking.
