Electronic cigarettes: an update on products, regulation, public health approaches and oral health

Electronic cigarettes remain a divisive topic amongst public health experts and researchers. The division hinges on the the role of e-cigarettes in public health, i.e., whether e-cigarettes represent a potential to compromise decades of public health efforts by driving smoking rates up, or an effective tool to drive smoking rates down. Dental settings are a strategic place for stop smoking interventions, with large proportions of the population attending regularly and harms of smoking often presenting early in the mouth. Dental professionals should be equipped with the necessary information to provide evidence-based advice and recommendations to their patients.

To update dental professionals and researchers on the current regulations, public health approaches, and oral health effects of prevailing novel nicotine products, with a focus on e-cigarettes.

Narrative literature review.

Regulatory approaches vary considerably around the world but in the UK and Europe, e-cigarettes are regulated as consumer or medicinal product, and their use is permitted. In the UK, e-cigarettes have increasingly been supported by public health institutions for smoking cessation as part of a Tobacco Harm Reduction strategy. The potential harms (including to oral health) from e-cigarette use are likely to be much less than from tobacco cigarettes.
