Brief Summary
A total of 40 patients with CP (20 smokers (S+CP) and 20 nonsmokers (S-CP)) and 40 periodontally healthy subjects (20 smokers (S+PH) and 20 nonsmokers (S-PH)), comprising 80 subjects, were included in this study. Baseline GCF samples were obtained from all subjects and clinical periodontal measurements, including probing depth (PD), clinical attachment level (CAL), plaque index (PI), and gingival index (GI), were recorded. In patients who had received initial periodontal therapy, GCF samples were obtained and all clinical periodontal measurements were recorded again during the 6th-8th weeks. GCF PGRP-1 levels were analyzed by enzyme-linked immunosorbent assay.

Study Arms (4)
Smokers with chronic periodontitis
EXPERIMENTALPatients who had teeth with 30% periodontal bone loss, presence of at least two nonadjacent sites per quadrant with probing pocket depths of ≥5 mm, and bleeding on probing were assigned as chronic periodontitis group Patients who have smoked for at least 10 years and a minimum of 10 cigarettes per day were assigned as current smokers.
Non-smokers with chronic periodontitis
EXPERIMENTALPatients who had teeth with 30% periodontal bone loss, presence of at least two nonadjacent sites per quadrant with probing pocket depths of ≥5 mm, and bleeding on probing were assigned as chronic periodontitis group Never smoked patients were included into the nonsmoker group
Smokers with periodontal healthy
NO INTERVENTIONIndividuals were diagnosed periodontally healthy as without attachment loss, periodontal disease history, whole mouth bleeding scores of \<10% and a probing depth of ≤3 mm Patients who have smoked for at least 10 years and a minimum of 10 cigarettes per day were assigned as current smokers.
Non-smokers with periodontal healthy
NO INTERVENTIONIndividuals were diagnosed periodontally healthy as without attachment loss, periodontal disease history, whole mouth bleeding scores of \<10% and a probing depth of ≤3 mm Never smoked patients were included into the nonsmoker group
Interventions
Scaling and root planing and polishing with specific curettes were performed to patients with CP and oral hygiene education was provided to each patient.
