Patients' knowledge and views about the effects of smoking on their mouths and the involvement of their dentists in smoking cessation activities.

Background: Smoking is correlated with a large number of oral conditions such as tooth staining and bad breath, periodontal diseases, impaired healing of wounds, precancer and oral cancer. These effects are often visible and in the early stages they are reversible after cessation of smoking. Dentists, as part of the health profession, are frequently in contact with the general population and there is evidence that they are as effective in providing smoking cessation counselling as any other healthcare group.
Aims and Methods: Patients' knowledge of the effects of smoking and their attitudes towards the role of dentists in smoking cessation activities were analysed via a self-completing questionnaire and compared depending on their smoking status (smokers and non-smokers).
Results: The results show that patients hold very positive attitudes towards dentists' role in smoking cessation. The results also show that although patients have a good knowledge of the effects of smoking on general health, smokers are significantly less aware of the relationship between smoking and gum disease and on wound healing.
Conclusions: Dentists should inform their patients about the oral effects of smoking and strongly advise them not to smoke, especially in patients diagnosed with periodontal disease and requiring surgical procedures.
