How e-cigarettes affect oral health has always been a concern for users. A research paper recently released by the American Chemical Society pointed out that propylene glycol, the main component of e-cigarette atomization liquid, can inhibit oral bacteria and induced inflammation, and smokers switch to e-cigarettes, or can effectively reduce the risk of oral diseases such as oral cancer.
The American Chemical Society is one of the world’s largest scientific organizations, authorized by the United States Congress, with more than 150 thousand members in 140 countries. Propylene glycol is mainly used to enhance the stability of electronic cigarette atomization liquid, and researchers have found through a group of animal experiments that propylene glycol has a certain antibacterial effect.
Studies have shown that in confined spaces, propylene glycol concentrations up to 0.5 ppm will play a rapid bactericidal effect on Streptococcus pneumoniae, fluovirus and other microorganisms. With the increasing concentration, propylene glycol can also inhibit the growth of many pathogenic bacteria such as E. coli and Streptococcus mutans. Among them, Streptococcus mutans is an important factor leading to tooth decay, and E. coli can cause gastrointestinal infection.
To further explore the impact of e-cigarettes on the human oral environment, the study selected 30 smokers and 30 e-cigarette users, respectively. And the first use of human oral cells to detect AP sites (purine-pyrimidine sites) – DNA damage will form AP sites, the higher the level of AP sites, on behalf of the more serious DNA damage, the more likely to lead to gene mutations and cancer.

“There are more than 700 kinds of bacteria in the mouth, and most patients with oral diseases are smokers.” British dental expert R. Holliday said: “The comparative study of e-cigarettes and cigarettes is very useful for us, and we hope that dentists can put aside their prejudices and learn more about the positive effects of e-cigarettes on the oral health of sick smokers.”
