Smoking is the major preventable risk factor in the initiation and progression of periodontal diseases. Periodontitis risk was found to be 3.9 times higher among smokers aged between 19-30 years and 2.8 times higher among smokers aged 31-40 years compared to non-smokers. Aggressive periodontitis (AgP), is characterized by a rapid attachment loss usually incompatible with the amount of plaque and dental calculus. It is often not possible to predict the prognosis of treatment with various treatment options in cases of aggressive periodontitis. It was hypothesized that non-smoker patients with generalized aggressive periodontitis (GAgP) will respond better to conventional mechanical non-surgical periodontal therapy compared to the smokers. Therefore, the aim of this study was to evaluate the effects of smoking on the outcomes of non-surgical periodontal treatment in terms of the clinical, biochemical and microbiological parameters.

Patients were motivated and instructed to brush with modified Bass technique and use interdental toothbrushes, dental floss. Each patient underwent quadrant scaling and root planning (SRP) under local anaesthesia over a 4-week period. Root planing (RP) was performed under local anaesthesia (2% lidocaine, epinephrine 1:100.000) and a standard curette set newly sharpened with Arkansas stone was used for each patient.

Change in Probing Depth (PD)
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
Change in Bleeding on Probing (BoP)
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
Change in Plaque Index (PI)
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
Changing of the salivary biomarkers
In the morning following an overnight fast, during which subjects were requested not to drink (except water) or to chew gum, whole saliva samples were obtained by expectorating into polypropylene tubes; clinical periodontal measurements and any necessary periodontal interventions were then carried out. Cytokine levels were assessed by Enzyme-linked immunosorbent assay (ELISA).
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
Changing of the serum biomarkers
Nine milliliters of venous blood were taken from the antecubital vein by a standard venipuncture method and centrifuged for 10 minutes at 3,000 rpm, separating serum from the cells. Cytokine levels were assessed by Enzyme-linked immunosorbent assay (ELISA).
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
Changing of the gingival crevicular fluid (GCF) biomarkers
GCF samples were obtained from buccal aspects of one interproximal site in each quadrant. Supragingival plaque was removed carefully by sterile curettes; the surfaces were dried and isolated by cotton rolls. Filter paper strips were placed in the orifices of the gingival sulcus/pocket for 30 seconds. Care was used to avoid mechanical trauma, and strips contaminated with blood were discarded. The absorbed GCF volume was estimated by a calibrated instrument. The readings of GCF sample volumes were converted to an actual volume (μL) by reference to the standard curve. Cytokine levels were assessed by Enzyme-linked immunosorbent assay (ELISA).
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
Changing of the amount of pathogen microorganisms
Plaque samples were collected from the same sites by sterile paper points from the base of the pockets. Paper points were inserted into the deepest part of the pocket and kept for 5 seconds. Paper points were then placed into propylene tubes. Real-time polymerase chain reaction was used for detection and quantification of bacterial cell copy numbers in 1 mg plaque.
Time frame: Baseline and 1 month, 3 month, 6 month after non-surgical periodontal therapy
