A study by researchers at British American Tobacco has actually revealed that e-cigarettes and tobacco heating items trigger considerably less staining to teeth than standard cigarettes.

For the very first time at BAT, researchers evaluated and compared an unique e-cigarette (EC), a tobacco heating item (THP) and a traditional cigarette for their influence on teeth enamel staining. The outcomes are released today in the AmericanJournal of Dentistry

While cigarette smoke triggered substantial enamel staining, vapour from the EC and aerosol from the THP triggered just very little staining (see Figure 1).

These next generation items (NGPs) do not include combustion; the vapour and aerosol they produce are less intricate and consist of considerably lower levels of particular toxicants compared to cigarette smoke.

It is popular that cigarette smoking triggers spots on teeth that can not quickly be eliminated by routine brushing, however little is understood about such results from NGPs. So researchers at BAT carried out in vitro teeth staining research studies to compare the result of an EC, BAT’s THP glo, and a recommendation cigarette (3R4F).

Tests were performed on enamel obstructs cut from bovine incisors. To simulate conditions in the mouth, the enamel blocks were very first bred with saliva to enable the development of a pellicle layer, a protective protein movie that typically forms onteeth The enamel blocks were exposed to the particle matter (separated from the smoke/vapour) for 14 days and after that entire smoke/vapour (comparable to one pack of cigarettes daily) for 5 days.

The enamel samples were evaluated in the past, throughout and after treatment; colour readings were figured out by an independent lab utilizing a recognized technique including a commercially offered spectrophotometer and qualified researchers.

Discoloration of enamel obstructs exposed to cigarette smoke appeared in just one day and continued to increase as the concentration of cigarette smoke increased. In contrast, direct exposure to vapour from the EC or THP led to little or no colour modification that was similar to the unattended controls.

“Many studies have postulated that it is the tar in cigarette smoke that stains teeth. We now have a method where we can rapidly assess in the laboratory the level of enamel discoloration by cigarette smoke and vapour from our ECs and THPs,” describes Annette Dalrymple, a senior researcher at BAT R&D.

“The data generated from this study clearly shows that the EC and THP assessed caused minimal discoloration—very promising for consumers of our NGPs. However, further studies are required to understand the long-term effect on teeth staining and oral health when smokers switch to using NGPs.”
