E-cigarettes Increase Potentially Harmful Bacteria in the Mouth
A recent study conducted by scientists at Ohio State University in Columbus has revealed that e-cigarettes can significantly alter the composition of bacteria in the mouth. The research team, led by Sukirth Ganesan, found that the oral microbiome of e-cigarette users resembled that of individuals with established periodontitis. The study, published in the journal Science Advances, analyzed the mouth flora of five groups of participants, including smokers of traditional cigarettes, e-cigarette users, and non-smokers. The results showed that both groups of e-cigarette users had increased levels of potentially harmful bacteria and inflammation-promoting immune responses in their mouths, similar to those found in traditional cigarette smokers.
The study also found that e-cigarette users had a faster formation of biofilm, a protective layer of bacteria that can cause inflammation and gum disease. The researchers noted that the changes in the oral microbiome were not related to the nicotine content of the e-cigarette liquids, but rather to the glycol and glycerin content, which provide the energy needed for biofilm production. The study’s co-author, Purnima Kumar, warned that e-cigarette users were already showing molecular changes similar to those seen in individuals with established periodontitis. Kumar also noted that switching from traditional cigarettes to e-cigarettes did not restore a healthy oral microbiome, but rather resulted in a shift to the bacterial profile of e-cigarette users.
While the Public Health England has stated that e-cigarettes are significantly less harmful than traditional tobacco cigarettes, the study’s findings suggest that e-cigarettes can still pose health risks. The study’s authors emphasized the need for further research to fully understand the long-term effects of e-cigarette use on oral health and overall health. The study’s findings also highlight the importance of maintaining good oral hygiene practices, regardless of smoking habits.
