The electronic cigarette harmful for the mouth

Because electronic cigarette smoke the death of a large number of cells of the mouth, according to researchers at Université Laval.

The work of the team of Dr. Mahmoud Rouabhia, Faculty of Dental Medicine at Laval University, were published in the Journal of Cellular Physiology. They show that many cells of the mouth exposed in the laboratory of electronic cigarette smoke die within days.

The team of Professor Rouabhia arrived at this conclusion after exposing cells of epithelium of gum to the electronic cigarette smoke, it is explained in a statement released Wednesday by the University Laval. “The oral epithelium is the first line of defense of the body against the outside world. His integrity protects us against including some 500 species of microorganisms that live in our mouth, “says the researcher.

To simulate what happens in a person’s mouth during a vapotage session, the researchers placed the epithelial cells in a small room containing some liquid acting saliva.

“Electronic cigarette smoke was introduced into the chamber using a pump with two” inhalations “5 seconds per minute for 15 minutes each day. Microscopic observations have shown that the percentage of dead or dying cells, which is 2% in the non-exposed cell cultures, rises to 18%, 40% and 53% after one, two and three days of exposure vapotage to smoke, “does it summarizes in the statement.

Not only of the water vapor

According to Dr. Rouabhia, electronic cigarette smoke is not, contrary to popular belief, only water vapor. “It does not contain tar compounds as the ordinary cigarette, but she exhibits all the same tissues of the mouth and airways to the compounds produced by heating vegetable glycerin, propylene glycol, flavoring and nicotine that one finds in the liquid of electronic cigarettes, “he lists.

The researcher says that the cumulative effects of these cell damage is not yet documented, but they are still worrying. “The disruption of the oral barrier that ensures our defense can increase the risk of infection, inflammation and periodontal disease. In the longer term, it could result in an increased risk of cancer. This is what we want to check the result of our work, “concludes Dr. Rouabhia.
