Abstract:
Oral cavity is an entrance of the human body and it is directly exposed by the smoke of tobacco. Thus oral cavity is the place where many disorders appear due to tobacco; such as periodontal disease, oral cancer, tooth loss, melanin pigmentation etc. Smoking also carries a poor prognosis of dental treatment. A smoking cessation or support intervention at dental setting has benefits because it is easy to motivate the smoking patients by showing them direct influence of tobacco on their oral health, possible to follow up the patients regularly, and feasible to start quitting before a substantial harm of tobacco to general health. It is important that various fields of health professionals co-operate closely to promote smoking cessation.
