Vapor Products Could Threaten Oral Health, Researchers Say

A new study suggests that the chemical components present in e-liquid can cause damage to healthy gum tissue cells when vaporized, and that the damage is comparable to that caused by exposure to cigarette smoke.

The study, which was published in the Oncotarget multidisciplinary medical journal, was led by Dr. Irfan Rahman, professor of environmental medicine at the University of Rochester School of Medicine and Dentistry in New York.

“We showed that when the vapors from an e-cigarette are burned, it causes cells to release inflammatory proteins, which in turn aggravate stress within cells, resulting in damage that could lead to various oral diseases,” Rahman said.

Another study published in the Journal of Cellular Physiology supports the findings from Rahman and his research team with data that found a “high rate of mouth cell death with exposure to e-cigarette vapor over just a few days.”

To collect this data, Dr. Mahmoud Rouabhia, of the Faculty of Dental Medicine at Université Laval in Canada and his colleagues placed epithelial cells from the mouth in a chamber that contained a liquid similar to saliva, according to Medical News Today (MNT), a leading healthcare internet publishing company.

The cells inside the chamber were then exposed to e-cigarette vapor which was pumped into the chamber to simulate vaping, at a rate of two five-second puffs every 60 seconds for 15 minutes a day, MNT reports.

The experiment was performed over three days and on analyzing the vapor-exposed epithelial cells under a microscope, the researchers identified a significant increase in the rate of cell damage and death.

“Damage to the defensive barrier in the mouth can increase the risk of infection, inflammation, and gum disease,” Rouabhia said. “Over the longer term, it may also increase the risk of cancer. This is what we will be investigating in the future.”
