The present study evaluated the prevalence of Porphyromonas gingivalis and the correlation between the bacterial culture method and the detection of immunoglobulin A (IgA) specific to theP. gingivalis fimbrial antigen in gingival crevicular fluid (GCF). P. gingivalis was isolated from 78.3% of subgingival plaque samples obtained from active sites and 34.7% of those from inactive sites of periodontal patients. P. gingivalis was isolated from only 4.7% of healthy subjects (control group). Immunoglobulins specific to the P. gingivalis fimbrial antigen were detected by enzyme-linked immunosorbent assay (ELISA). The overall agreement between the results of the P. gingivalis culture method and the results of specific IgA detection in periodontal patients was 71.7% for active sites and 58.7% for inactive sites. IgA specific to P. gingivalis was absent in GCF from all of the sites of healthy subjects. The results suggest that P. gingivalis is associated with the local production of specific IgA. The detection of IgA antibodies specific to P. gingivalis in GCF by ELISA may be used as a predictive parameter to reveal the early phase of the activation of recurrent periodontal infections.

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.

Studies on the link between periodontal disease and atherosclerosis have generated conflicting results and the mechanisms underlying this relationship are incompletely understood. Therefore, this study aimed to assess the levels in serum and in gingival crevicular fluid (GCF) of TNF-a, IL-1b and IL-6, to clarify the possible link between periodontitis and hyperlipidemia, as well as the effects of conventional periodontal treatment through scaling and root surfacing on these pro-inflammatory molecules. The study was carried out on a total of 40 subjects divided into two main groups: the study group (n=26) and control group (n=14). The cases included patients with atherosclerosis with prescribed diet (D) or antilipemic therapy with a drug from the statin group (S). Controls (C) were selected from systemically healthy subjects with chronic periodontitis. Samples were performed from crevicular fluid and serum, by determining the initial and post-treatment of TNF-a, IL-1b and IL-6. For all groups there were significant serum decreases in TNF-a, IL-1b and IL-6 from baseline, and the decreases were more significant IL-1b for statin group. Significant decreases were found in the crevicular fluid for all cytokines. The decrease was most evident for IL-6 in the statin group. Combining antilipemic periodontal therapy and treatment can provide beneficial effects on metabolism and control of inflammatory atherosclerosis by lowering serum pro-inflammatory cytokines.

Abstract Objectives Asymptomatic apical periodontitis (AAP) is one of the most widespread chronic inflammatory diseases in the field of dental medicine. Active matrix metalloproteinase (aMMP-8) previously demonstrated diagnostic potential as a biomarker for AAP in gingival crevicular fluid (GCF). The aim of this study was to determine the levels and diagnostic accuracy of aMMP-8 in GCF from teeth with AAP. Materials and Methods In this cross-sectional study, GCF samples were obtained from teeth with AAP (sample group, n = 31) and their contralateral teeth (control group, n = 31). Clinical and cone beam computed tomography (CBCT) parameters were used for the diagnosis and assessment of AAP and the determination of clinically healthy marginal periodontal tissues. One pool GCF sample per tooth was obtained from the whole crevice’s perimeter. aMMP-8 levels were determined by enzyme-linked immunosorbent assay (ELISA). Statistical Analysis Wilcoxon signed ranks test and Spearman rank correlation coefficient (rs) were used as statistical tools. The significance level was set at p < .05. Results The two groups demonstrated biomarker levels corresponding to a healthy marginal periodontal tissue. aMMP-8 levels were statistically and significantly higher in the samples collected from teeth with AAP. Lesions with greater volume showed correspondingly larger diameters. No statistically significant correlation between aMMP-8 levels and lesions’ volume or diameter was discovered. Conclusion GCF composition is modified by AAP only to a minimal extent. Further research is needed to substantiate the utilization of aMMP-8 as a potential biomarker for the diagnosis of the disease as well as to explore its relationship with other biomarkers.

Objective:  To assess the levels of IL-12, IL-15, IL-18, and IL-32 in the gingival crevicular fluid (GCF) and peri-implant crevicular fluid (PICF) in patients with gingivitis, periodontitis, and peri-implantitis before and one year after implant installation. Material and Methods: Forty-nine samples of GCF and PICF were collected from March 2018 to March 2019. The patients were classified: patients with gingivitis (n=7), patients with periodontitis (n=14), patients with peri-implantitis (n=4) and healthy patients (n=24). The crevicular fluid from the 49 patients was collected before implant installation (n=8) and one year after implant placement (n=8). The Enzyme-Linked Immunosorbent Assay (ELISA) was used to evaluate the levels of cytokines in crevicular fluid. Results: Patients with gingivitis, periodontitis, and peri-implantitis showed higher concentrations of IL-12, IL-15, IL-18, and IL-32 when compared with control group. In general, the levels of IL-12 and IL-15 increased when compared to the moments before and after implant installation. There was also an increase in the concentration of IL-18 in the control group volunteers after implant installation. Conclusion: The results and methodology of this study showed that there was no difference in the synthesis of IL-12, IL-15, IL-18, and IL-32 in healthy individuals or in those with periodontal injuries. However, there was an increase in the cytokines IL-12, IL-15, and IL-18 one year after implant installation, which would be increasing the inflammatory activity in peri-implantitis.

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.

ABSTRACT To evaluate alternative approaches to the serological diagnosis of dengue virus (DEN) infection, the detection of DEN-specific immunoglobulin M (IgM) and IgA antibodies in serum and saliva specimens was assessed in 147 patients with symptoms of DEN infection seen at the Ministry of Health in Nicaragua. Seventy-two serum samples were determined to be positive for anti-DEN antibodies by IgM capture enzyme-linked immunosorbent assay, the routine diagnostic procedure. Serum and saliva specimens were obtained from 50 healthy adults as additional controls. IgM was detected in the saliva of 65 of the 72 serum IgM-positive cases, 6 of the 75 serum IgM-negative cases, and none of the control group, resulting in a sensitivity of 90.3% and a specificity of 92.0% and demonstrating that salivary IgM is a useful diagnostic marker for DEN infection. Detection of IgA in serum may be another feasible alternative for the diagnosis of DEN infection, with serum IgA found in 68 (94.4%) of the IgM-positive cases. In contrast, detection of IgA in saliva was not found to be a useful tool for DEN diagnosis in the present study. Further studies of the kinetics of antibody detection in another set of 151 paired acute- and convalescent-phase serum samples showed that DEN-specific IgA antibodies were detected in more acute-phase samples than were IgM antibodies. Thus, we conclude that DEN-specific IgA in serum is a potential diagnostic target. Furthermore, given that saliva is a readily obtainable, noninvasive specimen, detection of DEN-specific salivary IgM should be considered a useful, cheaper diagnostic modality with similar sensitivity and specificity to IgM detection in serum.

Abstract PURPOSECarbonic anhydrase-2 (CA-2) plays a role in mineralization and calcification in organism. Strong evidence suggests that CA-2 is associated with urolithiasis. However, the relationship between CA-2 and urinary stone remains unclear. The study aimed to assess the association of urine CA-2 (uCA-2) level and the potential risk of urinary stone.METHODSFrom March 2017 to November 2019, a prospective cohort study was conducted on patients with urinary stones and healthy subjects to determine the pretreatment uCA-2 level detection by Enzyme linked immunosorbent assay (ELISA). The difference of uCA-2 level between patients with urinary stones and healthy subjects was compared. Then comparison between stone patients with complications and without complications was carried out as well as correlation analysis to detect factors associated with biomarker expression.RESULTS118 patients with urinary stones were into urinary stones group and 42 healthy subjects were into healthy control group. The mean pretreatment uCA-2 level was significantly higher in patients with urinary stones group than healthy controls group (P=0.028). Furthermore, The uCA-2 level was positive correlation with urinary stones complications (R=0.379, P=0.000), especially pain complications (R=0.524, P=0.000) and hematuria complications (R=0.374, P=0.000). Receiver operating characteristic curve (ROC) analysis that a uCA-2 level threshold of 10.94 ng/mL had 83.67% sensitivity and 68.12% specificity for predicting urinary stones complications. CONCLUSIONSExcessive uCA-2 excretion is a major risk factor for urinary stone. Our findings suggested that uCA-2 may be used as an unappreciated biomarker for the diagnosis urinary stone in patients and to predict its complications.

Background: Gingival crevicular fluid (GCF) is a biological fluid derived from the gingival sulcus and can be elevated in the inflammatory state of periodontal tissue, such as gingivitis. In previous studies, the number of GCF could also increase after panoramic radiographic exposure. Increase in GCF due to panoramic radiography is a sign of cell damage. Objective: To analyze the effects of panoramic radiography on the volume of GCF in wistar rats with gingivitis. Method: This type of research was true experimental with post test only and control group design. The sampling technique used was simple random sampling. A total of 25 wistar rats were classified into two control groups without exposure (state without gingivitis and gingivitis) and three groups treatment of exposure (state of gingivitis with 1 time, 2 times, and 3 times the exposure). GCF sampling using filter paper was carried out 10 minutes after panoramic radiographic exposure. The filter paper was stained by 2% ninhydrin solution, after that the GCF volume was calculated. Results: There was a significant difference in the number of GCF (p<0.05) in the group without gingivitis and exposure compared to all other groups, the gingivitis group without exposure compared to the gingivitis group with 3 times exposure, and the gingivitis group with 1 time exposure compared to the gingivitis group 3 times with exposure. Conclusion: Panoramic radiography can cause an increase in the volume of GCF in wistar rats with gingivitis. Keywords: GCF, gingivitis, panoramic radiography

Abstract Background The purpose of this study was to investigate gingival crevicular fluid (GCF) and serum folate-receptor 1 (FOLR1) levels in subjects with different periodontal status. Methods The study consists of three groups: Healthy group (n = 15), gingivitis group (n = 15) and chronic periodontitis group (n = 15). Clinical periodontal parameters including probing pocket depth (PPD), clinical attachment level (CAL), gingival index (GI) and bleeding on probing (BOP) were assessed. GCF and serum samples were collected from each patient and were analyzed FOLR1 levels by enzyme-linked immunosorbent assay. Results The values of FOLR1 in GCF were higher in gingivitis and periodontitis groups than among patient in control group (p < 0.016). Serum FOLR1 levels showed no significant difference between the groups. A significant correlation was observed between FOLR1 levels of GCF and BOP (p < 0.05). Conclusions Our preliminary data suggest that FOLR1 is not useful in monitoring the periodontal disease. Further studies are necessary to clarify the role, regulation and function of folate and it’s receptors in the pathogenesis of periodontal disease.
