Electronic Cigarettes and Oral Health

Area of Science:

• Oral Health
• Nicotine Products
• Public Health

Background:

• Electronic cigarettes (e-cigarettes) are increasingly popular novel nicotine products.
• E-cigarettes are perceived as less harmful than tobacco smoking and a potential smoking cessation aid.
• Concerns exist regarding e-cigarette health consequences, particularly long-term use and in non-smokers.

Purpose of the Study:

• To explore the oral health effects of electronic cigarette use.
• To review current evidence on cellular, microbiological, and clinical oral health impacts.
• To assess the balance of risks and benefits for smokers using e-cigarettes for cessation.

Main Methods:

• In vitro studies examining cellular effects.
• Microbiological studies analyzing oral microbiome changes.
• Epidemiological and clinical studies assessing oral health outcomes like dryness, irritation, and gingival diseases.

Main Results:

• In vitro studies show less pronounced cellular effects than tobacco smoke.
• E-cigarette users may have a more pathogenic oral microbiome.
• Clinical and epidemiological data suggest risks of oral dryness, irritation, and gingival diseases, though evidence is limited.

Conclusions:

• E-cigarette use presents potential oral health harms, necessitating reduced use in non-smokers.
• For smokers using e-cigarettes to quit tobacco, the benefits of cessation may outweigh short-term oral health risks.
• Further longitudinal research is crucial to understand the clinical significance of observed biological changes.
