Effects of Electronic Cigarettes on Periodontal Health: A Systematic Review and Meta-Analysis
Abstract
Objectives The use of electronic cigarettes “e-cigarettes,” or vaping is growing in popularity, especially among adolescents and young adults. While the effects of cigarette smoking on oral health are well-established, the exact impact that e-cigarettes may have on dental tissues is still uncertain. The aim of the current review was to summarize evidence related to the effect of vaping on the periodontal health status of e-cigarette users. Methods A comprehensive electronic search was performed using PubMed, Web of Science, and Scopus databases, until January 31st, 2024. Two independent reviewers participated in the screening of studies, data extraction, and assessment of the included studies. Any disagreements were resolved by a third reviewer the quality assessment was done using the Newcastle-Ottawa Scale to assess the risk of bias. A frequentist meta-analysis was performed using R Statistical Software. The random effects model was adopted. Data were described as mean difference (MD) and 95% confidence interval (CI). A p-value of ≤ .05 was deemed statistically significant. Results Ten studies met the eligibility criteria. Overall, the findings were consistent, with most studies showing that e-cigarette users are at greater risk of periodontal disease than nonsmokers, but that they have a lower risk than cigarette smokers. Pooling results showed lower mean probing depth (PD) among nonsmokers than e-smokers (MD: -1.91; 95% CI: [-3.36: -0.47]; p-value = .01) while it was…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
