Effects of smoking on periodontal tissues.

Background/aims: Most studies about the association between tobacco and periodontal disease have shown that tobacco negatively affects periodontal tissues, although some authors have failed to demonstrate such association. Very few studies have tried to find out whether the effect of tobacco on periodontal tissues was similar for women and men. The aims of this investigation were to confirm the possible relationship between tobacco consumption and periodontitis, to study the correlation between intensity of smoking and disease severity, and to investigate any differences between genders related to the effects of tobacco consumption in periodontal health.
