Introduction: Gingival Crevicular Fluid (GCF) has been referred to as a promising medium for detection of markers for periodontal disease activity. Analysis of GCF shows minute changes in biomarker levels well before the onset of clinical signs and symptoms; which helps to even predict a person’s predisposition towards periodontal disease occurrence. The elemental analysis of human blood serum is noteworthy in routine clinical practice as well as in medical research. Aim: This study was done to determine the changes in calcium and iron levels in GCF and serum in human subjects with normal periodontal health and those with disease. Materials and Methods: This was a cross-sectional study conducted from March 2019 to December 2019. Eight study subjects (4 healthy subjects and 4 periodontitis cases) were selected from the patients reporting to the Department of Periodontics at Tagore Dental College and Hospital, Chennai. The subjects were chosen based on inclusion and exclusion criteria and all patients were subjected to a clinical examination wherein the Probing Depth (PD) and Clinical Attachment Level (CAL) were recorded by a single examiner using William’s Periodontal probe. The GCF samples were collected by Capillary Tubing method. Blood was collected by venipuncture and centrifuged to provide serum samples. Dual viewing Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) was used to estimate Calcium and Iron in GCF and serum. SPSS version 21.0 was used for statistical analysis. Mann Whitney U test was used for comparing the groups. p-value less than 0.05 was considered statistically significant. Results: Serum iron levels were significantly less in periodontitis patients than healthy subjects (p-value 0.043). GCF iron level (p-value 0.386), GCF calcium level (p-value 0.149) and serum calcium level (p-value 0.564) did not show any major variation among subjects with normal periodontal health and those with disease. Conclusion: The findings of this study showed that iron and calcium are present in GCF and serum samples of healthy persons and patients with chronic periodontitis which can be detected using ICP-OES. A significant difference in serum iron levels between health and disease could indicate a patient’s predisposition towards developing periodontitis. Calcium levels in GCF and serum do not point towards periodontal disease activity.

SUMMARYIntroduction Fibronectin (FN) can interact with immunoglobulin G (IgG) molecules affecting the process of physiological elimination and causing abnormal deposition of immune complexes. The aim of the study was to analyze interaction between FN fragments and IgG molecules with different glycosylation profiles in gingival crevicular fluid (GCF) of patients with periodontal disease and healthy controls.Material and Methods The study included 30 patients with moderate and advanced periodontitis and 22 healthy subjects. IgG and FN content in GCF were measured as well as the presence of FN and galactose expression on IgG molecules.Results IgG content in GCF was five times higher in patients with moderate (p<0.01) and eight time higher in patients with advanced periodontitis (p<0.001) compared to healthy subjects. Also, hypogalactosylated forms of IgG were found in higher concentration in GCF of patients with advanced periodontitis compared to moderate periodontitis and healthy subjects (p<0.05). FN fragments of molecular mass 48 - 53 kDa were the most commonly found fragments in all three groups. Furthermore, in patients with advanced periodontitis, fibronectin fragments were attached to IgG molecules.Conclusion IgG and FN fragments form complexes in GCF in patients with periodontal disease and healthy subjects

ABSTRACT Aim Background and objectives: IL-1β is a potent stimulator of bone resorption and has been implicated in the pathogenesis of periodontal destruction. Therefore, this study was designed to compare the levels of IL-1β of chronic periodontitis patients with the healthy subjects. Another objective of this study was to correlate IL-1β levels with the clinical parameters of the periodontal disease progression. Methods For this study, total 60 subjects were chosen (30- healthy and 30-chronic periodontitis). Simplified oral hygiene index (OHI-S), gingival index (GI), periodontal disease index (PDI), probing depth (PD), tooth mobility, bleeding on probing (BOP) were recorded for all the subject. Gingival crevicular fluid (GCF) was collected and subjected for ELISA for estimation of IL-1β Results At the periodontal diseased sites, the IL-1β levels increased at least 2-fold as compared with healthy subjects. This increase was highly significant (p = 0.0000). Within the test group, IL-1β levels correlated positively and significantly with PDI, PD, BOP and tooth mobility. The correlations of IL-1β with PD (p = 0.000) and IL-1β with BOP (p = 0.0004) were highly significant. Interpretation and conclusion These data suggest that amount of GCF IL-1β is closely associated with periodontal status. This relationship may be valuable in monitoring periodontal disease activity. Clinical significance It could be stated from this study on IL- 1β that there seem to be a strong correlation between periodontal tissue destruction and IL-1β. Furthermore IL-1β level could also differentiate between active and inactive periodontal lesions. How to cite this article Chaudhari AU, Byakod GN, Waghmare PF, Karhadkar VM.

The past decades demonstrated that saliva and its components represent a remarkable diagnosis fluid with valuable clinical uses for both oral and systemic diseases. At the same time it is well established that oxidative stress is involved in a wide number of pathologies, including periodontitis. The specific aim of the present study which included 50 subjects is to determine if saliva can be used in clinical settings to correlate oxidative stress and tissue destruction markers with the severity of periodontal disease. An important oxidative stress marker - 8-hydroxydesoxyguanosine (8-OHdG) and a collagen degradation marker - beta-crosslaps (b-CTX) were quantified in both saliva and gingival crevicular fluid (GCF) using ELISA kits and were found to be significantly increased in the chronic periodontitis group when compared to respective controls (p[0.05). At the same time positive correlations were observed between whole saliva and gingival crevicular fluid (p[0.05). Significant correlations were also determined between GCF and salivary markers and clinical parameters of periodontal disease. Present results demonstrate that saliva and its components can successfully be used in clinical settings and represents a reliable tool for assessing periodontal disease severity.

The study is aimed at assessing the impact that periodontal disease and chronic hepatitis C could have on gingival crevicular fluid levels of the NLRP3 inflammasome, caspase-1 (CASP-1), and interleukin-18 (IL-18) and at evaluating whether the increased local inflammatory reaction with clinical periodontal consequences is correlated to their upregulation. Patients were divided into four groups, according to their periodontal status and previously diagnosed hepatitis C, as follows: (i) CHC group, chronic hepatitis C patients; (ii) P group, periodontal disease patients, systemically healthy; (iii) CHC + P group, patients suffering from both conditions; and (iv) H group, systemically and periodontally healthy controls. Gingival crevicular samples were collected for quantitative analysis of the NLRP3 inflammasome, CASP-1, and IL-18. CHC + P patients expressed the worse periodontal status and the highest NLRP3, CASP-1, and IL-18 levels, the difference being statistically significant ( p < 0.05 ). The P group patients also expressed significantly more elevated NLRP3, CASP-1, and IL-18 levels, as compared to nonperiodontal patients (CHC and H groups). Chronic hepatitis C and periodontal disease could have a significant influence on the upregulation of NLRP3 inflammasome and its components, possibly contributing to an increased local inflammatory reaction and clinical periodontal consequences.
