Impact of Electronic Cigarettes on Oral Health: a Review.
Mahmoud Rouabhia
Abstract
Electronic cigarettes (e‑cigarettes) are widely available, and their use is increasing worldwide. They are promoted as a safer alternative to combustible cigarette smoking and as an effective smoking cessation aid. E‑cigarettes are designed to provide smokers with the desired nicotine dose without burning tobacco. They contain flavoured humectants that include nicotine in concentrations of 0-36 mg/mL. Evidence suggests that e‑cigarettes are a better nicotine delivery method than combustible cigarettes and have reduced adverse general and oral health effects, compared with combustible cigarettes. However, although e‑cigarettes might be an acceptable harm-reduction strategy, the differential effects of e‑cigarettes and combustible cigarettes have been based on self-reported perceptions. In addition, a growing number of young people, who have never engaged in combustible cigarette smoking, are smoking e‑cigarettes, which may not be harmless. We analyzed peer-reviewed publications available through PubMed to summarize the effects of e‑cigarettes on oral health.
