Electronic Cigarettes, Traditional Cigarettes, and Oral Health

Background: Electronic cigarettes are increasingly preferred by young people today, and most people use them to quit smoking. However, the impact of e-cigarettes on human oral health is still controversial. It is debatable whether e-cigarettes are as safe, regulated, and harmless as one might believe, and whether they have potential side effects on the human body. Objective: In this paper, we reviewed the literature related to traditional cigarettes and e-cigarettes and oral health in recent years, and investigate the impact of e-cigarettes and traditional cigarettes on oral health from four aspects: analysis of the composition of e-cigarettes and traditional cigarettes, effects on oral cells, oral flora, and clinical oral health. Conclusion: Both e-cigarettes and traditional cigarettes have an impact on a person's oral health. However, extensive experimental data is needed to prove whether e-cigarette aerosol is more harmful to the oral cavity than cigarette smoke (CS).
