In a study on oral health, scientists from British American Tobacco have studied the discoloration of teeth. The results tell us that if smoking stains dentition quite quickly, the electronic cigarette will not cause discoloration!
TO HAVE BEAUTIFUL TEETH, IT'S STILL TIME TO SPEND!
A new study conducted by British American Tobacco showed that teeth exposed to cigarette smoke over a 2 week period discolored very quickly. Contrary to this, after 2 weeks of almost continuous exposure, teeth exposed to e-cigarettes or heated tobacco showed no signs of discoloration.
Stains on a smoker's teeth are usually yellow or even brown in color. Although this coloring is commonly referred to as nicotine coloring, it is not caused by nicotine, but by tar.
COMPARE THE EFFECTS ON TOOTHING TOOTHING AND VAPOTING!
As part of a larger study of oral health, scientists at British American Tobacco studied tooth discoloration. A prototype e-cigarette " Vype »And a heated tobacco product« Glo“, Were evaluated to make a comparison with smoking on the teeth.
A robot was used to produce smoke and steam. In each case, the smoke or vapor was collected on a filter pad and then a solvent was used to extract the solid material. The extraction was then tested using cow teeth.
Cow teeth are commonly used in laboratory experiments instead of human teeth. They are for example used to test oral hygiene products such as toothpaste or mouthwash.
The teeth were polished with sandpaper to create a surface close to human teeth. These were then incubated at body temperature in human saliva to create an environment mimicking that of the human mouth. This incubation results in the creation of a so-called dandruff layer on the teeth, which is the smooth film that you can feel on your teeth. It is the normal protein layer that forms on teeth when certain molecules in saliva bind to tooth enamel.
The teeth were incubated in an oven at body temperature and exposed to various extracts of cigarette smoke or e-cigarette vapor. Some teeth were also incubated in a solvent without any extract to act as a control.
RESULTS WITHOUT EQUIVOCAL!
After the first day, the teeth exposed to the cigarette smoke extract started to change color and within 14 days these teeth became darker and darker. Even with the naked eye, after just one day, the color changes with the cigarette extract were visible.
Unlike teeth exposed to smoke, those exposed to e-cigarettes or heated tobacco exhibited minimal change in color, similar to teeth from non-smokers.
