E-cigarettes May Not Stain Teeth, says Study

Conversely, exposure to vapour from the e-cigarettes or tobacco heating products resulted in little or no colour change that was comparable to the untreated controls

E-cigarettes and tobacco heating products cause significantly less staining to teeth than conventional cigarettes, a new study has found.

While cigarette smoke caused significant enamel discolouration, vapour from the e-cigarettes and aerosol from the tobacco heating products caused only minimal staining.

These next generation products do not involve combustion; the vapour and aerosol they produce are less complex and contain significantly lower levels of certain toxicants compared to cigarette smoke.

“Many studies have postulated that it is the tar in cigarette smoke that stains teeth,” said Annette Dalrymple, senior scientist at British American Tobacco in the UK.

“The study clearly shows that the e-cigarettes and tobacco heating products assessed caused minimal discolouration — very promising for consumers. However, further studies are required to understand the long-term effect on teeth staining and oral health when smokers switch to using next generation products,” Dalrymple added.

For the study, published in the journal American Journal of Dentistry, the team assessed and compared an e-cigarette, a tobacco heating product and a conventional cigarette for their impact on teeth enamel staining.

They assessed in the laboratory the level of enamel discoloration by cigarette smoke and vapour from e-cigarettes and tobacco heating products.

Tests were carried out on enamel blocks cut from bovine incisors — substitute for human teeth in dental research.

The enamel blocks were exposed to the particulate matter (isolated from the smoke/vapour) for 14 days and then whole smoke/vapour for five days.

The enamel samples were assessed before, during and after treatment and colour readings were determined using an established method involving spectrophotometer and trained scientists.

Discolouration of enamel blocks exposed to cigarette smoke was apparent in as little as one day and continued to increase as the concentration of cigarette smoke increased, the findings revealed.

Conversely, exposure to vapour from the e-cigarettes or tobacco heating products resulted in little or no colour change that was comparable to the untreated controls. (IANS)

With the Union Cabinet directing a blanket ban on e-cigarettes in the country with complete suspension of their manufacturing, import, export, distribution and storage, physicians welcomed the step while e-cigarette traders expressed shock and anger over the decision.

“Although, e-cigarettes are little less lethal then the conventional cigarettes, we cannot shun away the fact that it contains harmful ingredients. These chemicals can potentially affect the lungs and overall health of the individual in the long run,” Rajesh Chawla, Senior Pulmonologist at Indraprastha Apollo Hospital in New Delhi, told IANS.

Industry body TRENDS which represents importers, distributors and marketers of ENDS, or Electronic Nicotine Delivery Systems in India, termed the decision to ban e-cigarettes “ironic and erratic”.

“This ban on e-cigarettes on the basis of ‘selective sourcing of scientific and medical opinion’ and without holding a single stakeholder meeting is nothing short of a complete murder of democratic norms,” said Praveen Rikhy, Convenor, TRENDS (Trade Representatives of ENDS).

“All our representations sharing best practices from other countries – 70 developed countries have allowed regulated sale of e-cigarettes, have been completely ignored. We will now initiate a formal campaign to help MPs understand the issue, clarify misapprehensions and misinformation spread by lobby groups and support the farmer groups who see the growth of the e-cigarette sector as a global market opportunity for nicotine,” Rikhy said.

While e-cigarettes have been marketed as a way for adults to quit conventional smoking, a recent outbreak of lung illness associated with use of vaping products in the US has raised concerns about the safety of these products.

The Donald Trump administration on September 12 said that it plans to ban the sale of non-tobacco-flavoured e-cigarettes in the US following six deaths linked to vaping.

Health authorities have documented a total of 450 cases involving e-cigarettes, according to the US Centers for Disease Control and Prevention (CDC), which issued a health warning against vaping.

“I entirely support the idea of a ban on e-cigarettes; it is a step in the right direction,” Manoj Luthra, CEO, Jaypee Hospital in Noida, told IANS.

“E-cigarettes have been projected as a means to help people to quit smoking tobacco and also being non-polluting. However, these have their own health hazards and are addictive as well. These contain nicotine and other chemical vapours which will certainly have ill effects on the heart and lung and other organs as well,” he said. (IANS)
