Abstract:: Background. Electronic cigarettes are widely perceived as a safer and healthier option compared to traditional combustible tobacco cigarettes. They are commonly used as aids for smoking cessation and have gained popularity, particularly among younger individuals. To explore the potential impact of electronic cigarette use on oral health, we conducted a review of the existing literature. Our aim was to compare the oral microbiomes of tobacco smokers and electronic cigarette users with those of non-smokers. The oral cavity harbors a diverse array of microorganisms, each occupying specific niches. This symbiotic microbiota plays a crucial role in defending against external pathogens, thus maintaining the stability of the ecosystem and supporting the normal development of oral tissues and the immune system. Initial colonizers of oral surfaces primarily consist of facultative anaerobic bacteria, including various species of Streptococci and Actinomyces. In the subgingival region, where oxygen levels are lower, there is a shift in population composition, with an increase in the prevalence of strict anaerobes, particularly those belonging to the Bacteroidaceae spp.
