TAILIEUCHUNG - Intelligent Business Elementary Teacher's Book_1

Tobacco smoking mostly in the form of cigarette smoking has been accused of impairing microcirculatory system and the relevant changes in vascular formations and functions may have a negative influence on the immune and inflammatory reactions in periodontal tissues. Smokers were reported to have significantly less number of vessels in inflamed gingival tissue compared to non-smokers (Rezavandi et al. 2002). Long-term smoking has an established negative effect on the vasculature of periodontal tissues. Acute exposure to cigarette smoke induces gingival hyperaemia, which is caused by the concomitant increase in blood pressure against a small but significant sympathetically induced vasoconstriction in healthy gingiva (Mavropoulos et al. 2003) | Intelhgent Business Teacher s Book PEARSON Longman Elementary Business English Irene Barrall Nikolas Barrall The Economist Intelligent Business Teacher s Book Elementary Business English Irene Barra 11 Pearson Education Limited Edinburgh Gate Harlow Essex CM20 2JE England and Associated Companies throughout the world.
