Background Because of regulations made against smoking, and the rising popularity
of a healthy lifestyle there has been a visible change in the smoking habit of the
population in the last 15 years. The negative impact on the attitude toward smoking
forced the industry to develop new ways to satisfy the consumer’s nicotine need. That
is how heated tobacco products and a variety of ENDS (Electronic Nicotine Delivery
System), such as electronic cigarettes) have been invented. Objective This literature
review aims to summarise the oral effects of consuming e-cigarettes which have been
proven and publicised. Data Sources The main source of the study has been the publications
found through PubMed and NBCI (National Center for Biotechnology Information). Study
Selection Articles have been selected from the international literature if they had
any information on the oral effects of e-cigarettes. Data Extraction The information
from the articles has been categorised based on the tissue and the time they last.
Data Synthesis Electronic cigarettes cause a change in saliva flow and its composition,
a decrease in the blood supply of soft tissues and an immunosuppressed state in the
said area, therefore the incidence of some diseases are higher among the users. Components
of the e-liquid may cause damage to both soft and hard tissues, such as cancerous
lesions, inflammation, chronic periodontitis and neurodegeneration. Nicotine may be
absorbed by the surface of the teeth, causing patches, and some ingredients may be
beneficial to the bacterial flora of the oral cavity.
