Objectives. This study evaluated IL-17 and IL-11 in gingival crevicular fluid (GCF) of generalized chronic periodontitis (GCP) and generalized aggressive periodontitis (GAgP) patients in relation to periodontopathic bacteria.Subjects and Methods. GCF samples were collected from 65 subjects including 25 CP, 25 GAgP, and 15 controls (C) and analyzed for IL-17 and IL-11 by an enzyme-linked immunosorbent assay. Molecular detection of bacteria in the dental plaque was determined by polymerase chain reaction.Results. The total amount of IL-17 was significantly higher in GAgP group than in GCP and C groups(P<0.001). The IL-11 concentration was significantly higher in C and GCP groups than GAgP group(P<0.001). The IL-11/IL-17 ratio was significantly higher in the C group than in GCP and GAgP groups(P<0.05). Moreover, GAgP group showed lower ratios of IL-11/IL-17 when compared to GCP group. The high positivity ofP. gingivalisin the dental plaque was associated with significantly increased GCF levels of IL-17 in GCP and GAgP patients.Conclusions. The increased IL-17 level in GCF of GAgP suggests a potential role in the aetiopathogenesis. Meanwhile, the decreased ratio of IL-11/IL-17 might reflect an imbalance between the proinflammatory and anti-inflammatory cytokines in different periodontal diseases.

Aim:The aim of the present study was to investigate gingival crevicular fluid (GCF) calprotectin, osteocalcin and cross-linked N-terminal telopeptide (NTx) levels in health along with different periodontal diseases.Material and methods:Twenty chronic periodontitis (CP), 20 generalized aggressive periodontitis (G-AgP), 20 gingivitis and 20 healthy subjects were included. Probing depth, clinical attachment level, plaque index and papillary bleeding index was recorded. GCF calprotectin, osteocalcin and NTx levels were analyzed by enzyme-linked immunosorbent assay (ELISA).Results:CP, G-AgP and gingivitis groups had higher GCF calprotectin total amount compared to healthy subjects (p< 0.008). CP and G-AgP groups had similar, but higher levels compared to gingivitis groups (p< 0.008). CP and G-AgP groups had lower GCF osteocalcin total amount compared to gingivitis and healthy groups (p< 0.008). CP group had higher GCF NTx but lower osteocalcin total amount and osteocalcin/NTx ratio than the G-AgP group (p< 0.008)Conclusions:Our results suggest that elevated GCF calprotectin levels play a role as a reliable inflammatory marker in the pathogenesis of periodontal disease. Fluctuating GCF levels of osteocalcin and NTx might point out to the abnormal bone turnover in periodontitis. Our data document for the first time the role of NTx in the pathogenesis of different periodontal diseases.

Aim. Cathepsin C is the activator of the polymorphonuclear leukocyte-derived proteinase 3, which contributes to inflammatory processes. The aim of the present study was to investigate gingival crevicular fluid (GCF) proteinase 3 and cathepsin C levels in periodontal diseases.Design. Eighteen patients with chronic periodontitis (CP), 20 patients with generalized aggressive periodontitis (G-AgP), 20 patients with gingivitis, and 18 healthy subjects were included in the study. Periodontal parameters including probing depth, clinical attachment level, papilla bleeding index, and plaque index were assessed in all study subjects. GCF proteinase 3 and cathepsin C levels were analyzed by ELISA.Results. GCF proteinase 3 total amount was significantly higher in diseased groups compared to control group, after adjusting ageP<0.05. No differences were found in GCF cathepsin C levels among the study groupsP>0.05. Periodontal parameters of sampling sites were positively correlated with GCF proteinase 3 total amountsP<0.01but not with cathepsin C total amountsP>0.05.Conclusions. Elevated levels of GCF proteinase 3 in CP, G-AgP, and gingivitis might suggest that proteinase 3 plays a role during inflammatory periodontal events in host response. However, cathepsin C in GCF does not seem to have an effect on the pathogenesis of periodontal diseases.

Background: Plasma glutathione peroxidase (eGPx) is an important selenium containing antioxidant in human defense against oxidative stress. While crevicular fluid (GCF) eGPx levels and its association with periodontal disease is well documented, there is no data on correlation of GCF and serum eGPx levels in chronic periodontitis. Hence this study was undertaken to further probe into the role of oxidative stress in periodontal diseases and effect of nonsurgical periodontal therapy (NSPT) by correlating GCF and serum levels of eGPx.Materials and methods: Thirty subjects (16-Males and 14-Females; age: 30–38 years) participated in the study. The subjects were divided, based on gingival index, probing pocket depth and clinical attachment level into: Healthy (group-1,n=10), Gingivitis (group-2,n=10) and Periodontitis (group-3,n=10). Chronic periodontitis patients after NSPT constituted group 4. GCF and serum samples collected from each subject were quantified for eGPx levels using Enzyme linked Immunosorbent Assay.Results: The mean eGPx concentrations increased from health (14.01 ng/μl and 78.26 ng/ml) to gingivitis (22.86 ng/μl and 90.44 ng/ml) and then to periodontitis (29.89 ng/μl and 103.43 ng/ml), in GCF and serum respectively. After NSPT, there was statistically significant reduction in eGPx concentration in GCF and serum (19.41 ng/μl and 85.21 ng/ml). Further, all the GCF eGPx values showed a positive correlation to that of serum eGPx level.Conclusion: Thus, increased eGPx concentration in GCF can be considered as an indicator of local increase in oxidative stress. While, increase in serum eGPx levels indicates that periodontal disease can also lead to increased oxidative stress at the systemic level.

Cystatin C (CSTC) is an inhibitor of cysteine proteinases and could play a protective and regulatory role under inflammatory conditions. The present study was designed to assess the concentration of CSTC in gingival crevicular fluid (GCF) and serum, to find out their association if any, in periodontal health and disease. 30 subjects were selected divided into 3 groups consisting of 10 subjects in each group based on clinical parameters: periodontally healthy group, gingivitis group and chronic periodontitis group, while, chronic periodontitis group after 8 weeks of the treatment (scaling and root planing) constituted after periodontal therapy group. GCF and serum samples were collected from all subjects to estimate the levels of CSTC by ELISA. The mean CSTC concentration in GCF and serum was observed to be the highest in periodontitis group and lowest in periodontally healthy group with intermediate concentration in gingivitis group and after periodontal therapy group. CSTC concentration in GCF and serum increased proportionally with the severity of periodontal disease (from health to periodontitis group) and decreased after treatment. This suggests that CSTC increases with disease progression to prevent further periodontal degeneration and decreases after treatment due to bone metabolic homeostasis. Further, longitudinal prospective studies involving larger population are needed to confirm the findings of present study and to better understand the role of CSTC in the pathogenesis of periodontal diseases.

Background/Purpose. Chronic periodontitis is an inflammatory disease of gums that causes loss of supporting structures of teeth, that is, gingiva, periodontal ligament, cementum, and alveolar bone. Levels of various cytokines in the serum, gingival tissues, and gingival crevicular fluid in patients with chronic periodontitis have been studied, but limited data are available on the level of cytokines in saliva. Therefore, a study was designed to determine levels of salivary IL-6 and IL-17 in patients with calculus associated chronic periodontitis. Materials and Methods. It was a comparative, cross-sectional study that is comprised of 41 healthy controls and 41 calculus associated chronic periodontitis patients (CP patients). According to the degree of attachment loss, CP patients were subcategorized as mild (CAL 1-2 mm), moderate (CAL 3-4 mm), and severe (CAL > 5 mm) forms of periodontitis. Salivary levels of IL-6 and IL-17 were determined using enzyme-linked immunosorbent assay (ELISA) technique. Data was analyzed using SPSS 20.0. Results. Between healthy controls and CP patients (moderate and severe disease), a statistically significant difference was observed in the concentrations of IL-6 and IL-17. In CP patients, the highest mean ± SD of salivary IL-6 and IL-17 was observed in severe CP, followed by moderate and mild CP. Regarding level of IL-6, a statistically significant difference was observed between mild and severe disease and between moderate and severe subcategories of CP patients. Similarly, statistically significant difference was observed in the level of IL-17 between mild and moderate, mild and severe disease, and moderate and severe disease. Conclusion. The levels of salivary IL-6 and IL-17 were increased significantly in calculus associated CP patients as compared to healthy controls and these levels increased with the progression of CP. Clinical Significance. Salivary levels of IL-6 and IL-17 may help in the subcategorization of CP.

ABSTRACT Objectives To explore the expression of miR-34a and its effect on expression of matrix metalloproteinases (MMPs) during orthodontic tooth movement (OTM). Materials and Methods Twenty patients, age 12–18 years old, who underwent orthodontic treatment were enrolled. The expression of miR-34a and MMPs (MMP-1, MMP-2, MMP-3, MMP-8, MMP-9, and MMP-14) were detected in gingival crevicular fluid by enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction at different time points. The miR-34a mimics or inhibitors were transfected into human periodontal ligament (hPDL) cells, and the MMP expression was measured by ELISA. Results The miR-34 expression in GCF on both the tension and pressure sides after orthodontic treatment were significantly downregulated, while the levels of MMPs were significantly upregulated compared with baseline level. The levels of miR-34 and MMPs returned to baseline level 3 months after orthodontic treatment. The expression of miR-34 was negatively correlated with the expression of MMP-2, MMP-9, and MMP-14. After transfection with miR-34, the MMP-2, MMP-9, and MMP-14 expression by hPDL cells were significantly downregulated compared with miR-control and miR-34 inhibitor. Conclusions Downregulated miR-34 expression was positively correlated with MMP-2, MMP-9, and MMP-14 expression. The miR-34a transfection into hPDL cells inhibited expression of MMPs. The results suggest that miR-34a is involved in expression of MMPs during OTM.

Chronic periodontitis (CP) is an infection that affects the teeth supporting structure. Macrophage migration inhibitory factor (MIF) is an important effector cytokine of the innate immune system. Due to its functional characteristics, MIF may be involved in the immunopathology of CP. The aim of the present study was to evaluate MIF levels in gingival crevicular fluid (GCF), saliva, and serum of CP patients. A cross-sectional study was conducted on 60 subjects divided into two groups: subjects with CP (n= 30) and periodontally healthy subjects without CP (n=30). MIF was quantified in GCF, saliva, and serum of all participants by enzyme-linked immunosorbent assay. MIF concentrations were higher in GCF, saliva, and serum in the group with CP compared with the group without CP and a higher MIF concentration was observed in GCF (p=0.001) and saliva (p=0.009) in the group with CP. MIF intragroup comparisons between fluids demonstrated significant high levels of MIF in saliva compared with GCF and serum in both study groups (p<0.05). A positive correlation was found between clinical signs and MIF concentration in GCF (p<0.05). There is an association between the MIF and the clinical signs of the disease. Therefore, MIF could have an important role in the pathology and progression of CP.

Purpose. The aim of this study was to analyse the levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) in gingival crevicular fluid (GCF) of patients with chronic periodontitis prior to and following surgical and/or nonsurgical periodontal therapy for a period of 32 weeks.Methods. GCF samples were obtained from 24 nondiseased and 72 diseased sites of 12 periodontal patients prior to as well as at 6, 16, and 32 weeks following non-surgical and surgical periodontal therapy. IL-6 and IL-8 levels were determined by enzyme-linked immunosorbent assay (ELISA).Results. Periodontal treatment improved all clinical parameters. Both treatment modalities resulted in similar IL-6 as well as IL-8 levels. Mean IL-6 and IL-8 concentrations were significantly higher in non-diseased compared to diseased sites and increased significantly following treatment in diseased sites. Mean total amounts of IL-6 and IL-8 (TAIL-6, TAIL-8) did not differ significantly between diseased and nondiseased sites, while following therapy TAIL-8 levels decreased significantly.Conclusions. The data suggest that periodontal therapy reduced the levels of IL-8 in GCF. However, a strong relationship between IL-6, IL-8 amounts in GCF and periodontal destruction and inflammation was not found.

Background. Proinflammatory and anti-inflammatory cytokines play a key role in the pathogenesis of periodontal diseases. Secretion of bioactive IL-35 has been described by T regulatory cells () and is required for their maximal suppressive activity. are involved in the modulation of local immune response in chronic periodontitis patients.Objective. Hence, the present study was aimed to investigate the expression of IL-35 mRNA in chronic periodontitis and aggressive periodontitis patients.Materials and Methods. The present study was carried out in 60 subjects, which included 20 chronic periodontitis patients, 20 aggressive periodontitis patients, and 20 periodontally healthy controls. IL-35 mRNA expression in gingival tissue samples of all subjects was semiquantitatively analyzed using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR).Results. The present study demonstrated the expression of IL-35 mRNA in gingival tissues of all the three groups. IL-35 mRNA expression was highest in chronic periodontitis subjects () as compared to the aggressive periodontitis group () and least seen in healthy patients ().Conclusion. The increased expression of IL-35 in chronic and aggressive periodontitis suggests its possible role in pathogenesis of periodontitis. Future studies done on large samples with intervention will strengthen our result.
