Brief summary
The aims of our study were 1) to evaluate levels of gingival crevicular fluid( GCF) human cathelicidin peptide LL-37 and serum vitamin D3 in smoker and non-smoker patients with chronic periodontitis(CP) 2) to determine whether any correlation between GCF LL-37 and vitamin D3 serum levels exist and 3) to asses the correlation between clinical parameters and biochemical markers
Detailed description
Background: Cathelicidin LL-37, an antimicrobial peptide, is part of the host innate immune response in the oral cavity. The aims of this study are to evaluate; gingival crevicular fluid (GCF) levels of LL-37, serum vitamin D3 levels and periodontal clinical recordings in smoker and nonsmoker patients with chronic periodontitis (CP). Methods: This study consisted a total of 60 volunteers including 20 smoker patients with CP (CP-1 group), 20 non-smoker patients with CP (CP-2 group) and 20 periodontally healthy subjects (CTRL group). Prior to participation, the design and purpose of the research were explained to each subjects, and written informed consent form was obtained from 60 individuals before the study. The periodontal status of the patients were determined by measuring the probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI) All clinical parameters were measured on six sites per tooth from the full-mouth teeth (mesiobuccal, distobuccal,midbuccal, mesiolingual, distolingual and midlingual) using a William's periodontal probe calibrated in millimeters by the same examiner. All samples were obtained on the day following clinical examinations of the individuals. The deepest six pockets site per individual were chosen for collection of GCF across both of the periodontitis groups. Six pocket locations showing a lack of clinical inflammation were also tested to guarantee collection of a sufficient volume of GCF across the CTRL groups. GCF levels of LL-37 were measured by ELISA and serum levels of vitamin D3 were analysed by High-performance liquid chromatography (HPLC). Statistical analysis were performed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Serum D3 Vitamin levels | Baseline | The plasma levels of vitamin D3 were greater in the CP-2 group than in the CP-1 group. But, no statistically significant difference was determined between the CP groups (P\>0.05) |
| Gingival Crevicular fluid(GCF) LL-37 levels | Baseline | The concentration of LL-37 in GCF was significantly higher in both of the CP groups than in the CTRL group (p\<0.001). Although GCF LL-37 concentration levels were greater in the CP-1 group than in the CP-2 group, the difference did not reach the statistical significance between the CP groups (p\>0.05). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| gingival index (GI) | Baseline | The full-mouth and sample sites GI recordings were significantly higher in both CP groups (CP-1 and CP-2) than in the CTRL group (p\<0.001). |
| Plaque index (PI) | Baseline | The full-mouth and sample sites PI recordings were significantly higher in both CP groups (CP-1 and CP-2) than in the CTRL group (p\<0.001). were measured on six sites per tooth from the full-mouth teeth |
| Clinical attachment level (CAL) | Baseline | The full-mouth and sample sites CAL recordings were significantly higher in both CP groups (CP-1 and CP-2) than in the CTRL group (p\<0.001). |
| Probing depth (PD) | Baseline | The full-mouth and sample sites PD recordings were significantly higher in both CP groups (CP-1 and CP-2) than in the CTRL group (p\<0.001). |
| GCF volume | Baseline | The GCF volume was notably higher in both CP groups than in CTRL group (p\<0.001). |
