Brief Summary
This study comparatively evaluate the expressions of MMP-2 and MMP-9 in smoker vs non-smoker chronic periodontitis patients as well as periodontally healthy subjects. the hypothesis of this study was that smoking may interfere with periodontal disease by effecting MMP-2 and MMP-9 expressions.

Outcome Measures
Primary Outcomes (1)
expression of gelatinases levels in gingival tissue among groups
In chronic periodontitis group, after recording the clinical parameters, gingival tissues were harvested from the deepest periodontal pocket. Whereas in periodontally healthy group, gingival tissues were collected during crown-lengthening surgery or during an extraction of a teeth for orthodontic reasons. In both groups the samples include both sulcus/pocket epithelium and underlying connective tissues. The expression of MMP-2 and MMP-9 is measured immunohistochemically
