Materials and Methods: 28 CP and 17 GAgP patients were included in the study and their cigarette consumption was determined by verbal questioning. In each patient, 4 sites with pocket depths of 5mm or greater were selected. At each site the modified gingival index (MGI), plaque index (PlI), bleeding on probing (PD), suppuration (Supp), probing depth (PD) and relative attachment level (RAL) were recorded. After the clinical measurements were recorded, a subgingival plaque sample was taken. Each patient underwent scaling and root planing and reviewed 8 weeks later and re-sampled. For PCG analysis, the primers for A. actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythensis and Treponema denticola were used. The data were analyzed for differences between smoker and non-smoker CP and GAgP groups before and after treatment.
