The impact of tobacco smoking and electronic cigarette vaping on salivary biomarkers. a comparative study.

Introduction:
This article examines the impact of tobacco smoking and electronic cigarette vaping on salivary biomarkers, specifically interleukin-1 beta (IL-1β) and transforming growth factor-beta (TGF-β). The study aims to compare the levels of these biomarkers in cigarette smokers, electronic cigarette users, and non-smokers to highlight the influence of e-cigs and cigarette smoking on the levels of biomarkers of tissue injury and inflammation.

Key Points:

* The study involved 150 student volunteers, categorized into three groups: cigarette smokers, electronic cigarette users, and non-smokers.
* The study assessed the salivary levels of IL-1β and TGF-β using ELISa.
* The results showed that cigarette smokers had significantly higher levels of IL-1β and TGF-β than non-smokers and electronic cigarette users.
* The study also found a significant difference in IL-1β levels between electronic cigarette users and non-smokers.
* The authors suggest that electronic cigarettes can pose a risk of developing systemic diseases but less than conventional cigarettes.
* The study provides new evidence supporting the hazardous effects of e-cigs using a cost-effective, non-invasive method.
* The study highlights the importance of considering the type of smoker when investigating inflammatory biomarkers, which may be beneficial to future regulatory and translational investigations.

Main Message:
The study provides compelling evidence that both tobacco smoking and electronic cigarette vaping can affect salivary biomarkers of tissue injury and inflammation. While electronic cigarettes may pose less risk than conventional cigarettes, they are not without harm. The study underscores the importance of continued research into the health effects of electronic cigarettes to inform regulatory policies and protect public health.
