AB  - Purpose The health implications related to electronic cigarettes are not fully understood and has created a public health concern. The purpose of this narrative review was to highlight the oral and systemic health concerns associated with electronic cigarettes and compare these concerns to those associated with conventional tobacco cigarettes.Methods The literature was obtained from PubMed, Ovid Medline, CINAHL, and Scopus databases in June 2021 and updated in February 2023. Sources were chosen based on the following inclusion criteria: date of publication between 2011 and 2023 and written in English. Articles were excluded based on irrelevance to the topic, weak study designs, lack of outcome data, low quality randomized control trials, unavailability of the full text article, and non-empirical research designs. The Cochrane tool, ROBINS-I, was used to assess the risk of bias.Results A total of 78 studies were included in the review. E-cigarette use was associated with significant adverse effects for cardiovascular, respiratory, immunological, and periodontal health as compared to nonusers; however, impacts were worse with conventional smoked cigarettes. Long term health effects remain unknown with e-cigarettes, but associations have been identified with periodontal and peri-implant disease, oral cancer, and mental health disorders. The heterogeneity of e-cigarette use related to vaping behavior, devices, and liquids limits the ability to generalize results. There is a need for the development of a research standard for exposure methods to establish a consensus with e-cigarette use and support the validity of results among researchers.Conclusion According to current research, e-cigarettes may induce less harm than traditional tobacco products, but e-cigarettes do not remove the carcinogenic and toxic risk that has been associated with conventional cigarettes. Further research is needed to make broad conclusions on the safety of e-cigarettes compared to conventional cigarettes and to nonusers.
