Brief Summary
Periodontitis patients, 40 cigarette smokers and 40 non-smokers (defined by cotinine measures in serum), were recruited to this double arm prospective cohort study. Data were collected 3 months following non-surgical and surgical periodontal treatment, and following 12 months with supportive periodontal therapy. Data collected were clinical attachment level, probing depth, bleeding on probing,oral bacteria, serum, blood (PAXgeneBlood), and gingival crevicular fluid.

Eligibility Criteria
You may qualify if:
- healthy subjects
- age 35-75 years
- diagnosed with chronic periodontitis
- at least four non-adjacent teeth with proximal sites with a PD ≥6 mm and clinical attachment loss ≥5 mm with BoP and no radiographic signs of apical pathology.
- either smokers (\>10 cigarettes per day for at least 5 years) or non-smokers (never smoked or not within the last 5 years).
You may not qualify if:
