According to the data published in the Journal of Endodontics, active smokers with their habit significantly reduce the activity of the immune system. This explains why Smoking not only increases the likelihood of developing cancer and lung diseases, but also contributes to the development of deafness and significantly accelerates aging.
American scientists from the University of Case Western Reserve in Cleveland opened another negativeaspects from addiction to cigarettes. It turned out that smokers are twice as likely to suffer from gum disease, tooth decay and severe forms of pulpitis (inflammation of dental tissue) in connection with the “dead” of immune cells in the oral cavity.
Scientists have studied how tobacco smoke affects the tissue of the teeth. They gathered a group of 70 patients with neglected caries, smokers and non-smokers. Analyzing the pulp samples, taken from volunteers, experts found that in samples from smokers was virtually no molecules of substances that stimulate the immune system to fight the components that trigger inflammation.
“Initially, we expected to see that in smokers the levels of certain signaling substances, work-related immunity will be low, but to our surprise, these defensive molecules was not just a little – they are generally absent in the pulp of the tooth,” the scientists said in the journal.
Thus, experts say, it becomes clear why smokers are prone to severe dental disease – tobacco smoke kills them in the mouth substance that encourages the immune system to fight illnesses. According to them, due to the effect of tobacco, the activity of the immune system in smokers can be reduced similarly in other organs and tissues. Scientists are reminded that approximately 60% of smokers die prematurely because of the enthusiasm of tobacco, and not for other reasons.
