Dr James Pankhurst, from University College London, lead author of the paper, said: “Our study shows that e-cigarettes stain teeth much less than traditional cigarettes, which may be related to the fact that e-cigarettes do not contain tar and other harmful substances. In addition, we found that e-cigarettes also had less impact on the oral microflora, which means that e-cigarette users are less likely to suffer from gingivitis and dental caries.”
Dr. Pankhurst and his team conducted a 12-month randomized controlled trial of 50 long-term smokers, half of whom were assigned to use e-cigarettes and the other half continued to use traditional cigarettes. They assessed the participants’ tooth color, oral flora and indicators of oral health every three months.
The results showed that the group using e-cigarettes showed no significant change in tooth color, while the group using traditional cigarettes showed significant yellowing of teeth. In addition, the diversity and balance of oral flora in the group using e-cigarettes is also better than that in the group using traditional cigarettes, which indicates that their oral environment is healthier.
Dr Pankhurst said: “This is the first long-term trial to compare the oral health effects of e-cigarettes and conventional cigarettes, and our findings provide further evidence that e-cigarettes are an effective smoking cessation tool. We hope this study will encourage More smokers are considering switching to e-cigarettes, improving their oral health and overall health.”
