Electronic Cigarettes: Trends, Health Effects and Advising Patients Amid Uncertainty.

Dental professionals can be effective tobacco prevention and cessation partners. Electronic cigarettes (e-cigarettes), which deliver aerosolized nicotine but fewer toxicants than found in cigarette smoke, present new and contentious questions for clinicians, patients, and researchers. Evidence suggests e-cigarettes are not harmless but are less dangerous than cigarettes. Smoking cessation effectiveness is unproven and oral and systemic health effects remain under study. Dental professionals must stay informed to provide patients truthful information as new data emerge.
