Periodontal disease is a chronic inflammatory disease of the periodontal tissue. The periodontal inflamed surface area (PISA) is a proposed index for quantifying the inflammatory burden resulting from periodontitis lesions. This study aimed to investigate longitudinal changes in the periodontal status as evaluated by the PISA following the active periodontal treatment. To elucidate the prognostic factors of PISA, mixed-effect modeling was performed for clinical parameters, tooth-type, and levels of periodontal pathogens as independent variables. One-hundred-twenty-five patients with chronic periodontitis who completed the active periodontal treatment were followed-up for 24 months, with evaluations conducted at 6-month intervals. Five-times repeated measures of mean PISA values were 130+/−173, 161+/−276, 184+/−320, 175+/−417, and 209+/−469 mm2. Changes in clinical parameters and salivary and subgingival periodontal pathogens were analyzed by mixed-effect modeling. Plaque index, clinical attachment level, and salivary levels of Porphyromonas gingivalis were associated with changes in PISA at the patient- and tooth-level. Subgingival levels of P. gingivalis and Prevotella intermedia were associated with changes in PISA at the sample site. For most patients, changes in PISA were within 10% of baseline during the 24-month follow-up. However, an increase in the number of bleeding sites in a tooth with a deep periodontal pocket increased the PISA value exponentially.

Chronic periodontitis is a silent infectious disease prevalent worldwide and affects lifestyle-related diseases. Therefore, efficient screening of patients is essential for general health. This study was performed to evaluate prospectively the diagnostic utility of a blood IgG antibody titer test against periodontal pathogens. Oral examination was performed, and IgG titers against periodontal pathogens were measured by ELISA in 1,387 individuals. The cut-off value of the IgG titer was determined in receiver operating characteristic curve analysis, and changes in periodontal clinical parameters and IgG titers by periodontal treatment were evaluated. The relationships between IgG titers and severity of periodontitis were analyzed. The best cut-off value of IgG titer against Porphyromonas gingivalis for screening periodontitis was 1.682. Both clinical parameters and IgG titers decreased significantly under periodontal treatment. IgG titers of periodontitis patients were significantly higher than those of healthy controls, especially in those with sites of probing pocket depth over 4 mm. Multiplied cut-off values were useful to select patients with severe periodontitis. A blood IgG antibody titer test for Porphyromonas gingivalis is useful to screen hitherto chronic periodontitis patients (ClinicalTrials.gov number NCT01658475).

The progression of periodontitis depends on interactions between the periodontal pathogens and the host immune cytokines, including interleukin (IL)-1β and IL-18. Production of IL-1β is regulated by NOD-like receptors family pyrin domain containing 3 (NLRP3). This study aimed to evaluate the effect of periodontal treatment on the concentrations of IL-18 and NLRP3 in patients with chronic periodontitis. In this experimental study, 18 patients with chronic periodontitis and a mean age of 46.2±8.95 years, were included. The gingival crevicular fluid (GCF) was collected at the beginning of the study, 4 weeks after non-surgical (phase I), and 4 weeks after surgical periodontal treatment. The levels of NLRP3 and IL-18 were measured; using an enzyme-linked immunosorbent assay. Pearson correlation test was used to analyze the concentration of NLRP3 and IL-18 before and after the treatments with CAL and PD. There was a significant association between the level of NLRP3 and the mean values of PD and CAL before treatment. After each treatment phase, a significant decrease was observed in the NLRP3 level. There was no significant relationship between IL-18 and clinical parameters before and after periodontal treatments. Given the possible association between the level of NLRP3 and clinical parameters, we suggest it as a possible indicator of inflammation in chronic periodontitis and an index for evaluating the treatment outcome.

INTRODUCTION: Patients seem to adhere better to short-term periodontal treatment schemes. Besides, time-reduced treatments are more cost-effective. However, the degree of benefits related to this type of treatment still requires additional investigations. AIM: The present short-term study evaluated clinical and microbiological outcomes, from baseline to 3-months, of chronic periodontitis subjects treated by the one-stage full-mouth disinfection protocol. MATERIAL AND METHOD: Sixteen chronic periodontitis subjects (mean-age 49.87 ± 8.22) who met inclusion/exclusion criteria were included. A calibrated examiner measured whole-mouth plaque and gingival indices, periodontal pocket depth and clinical attachment level at baseline and at 3-months. Subgingival samples were also collected from the 5 most diseased periodontal sites to determine total bacterial load and levels of P. gingivalis and S. oralis by real time qPCR. Periodontal treatment consisted of full-mouth manual debridement plus wide intraoral use of chlorhexidine in gel and solution. Additionally, after debridement, individuals rinsed 0.12% chlorhexidine at home twice a day for the following 2 months. Data monitored were compared by paired Student-t test (p<0.05). RESULT: Statistical analysis revealed that, in general, one-stage full-mouth disinfection treatment provided significant clinical and microbiological improvements at 3-months. Total bacterial load showed one of the most pronounced reductions from baseline to 3-months (p=0.0001). Also, subgingival levels P. gingivalis and S. oralis reduced overtime. CONCLUSION: After a short period of monitoring, chronic periodontitis subjects showed clinical and microbial improvements following one-stage full-mouth disinfection treatment.

Chronic periodontitis is the most common type of periodontitis and it is associated with various species of microorganisms. Enteric rods, Pseudomonas, Staphyloccocus and Candida have been retrieved from periodontal pockets of patients with chronic periodontitis and correlated to cases of superinfection. Local or systemic antibiotic therapy is indicated to reinforce the effects of the conventional mechanical therapy. Minocycline has been suggested as one of the most effective drugs against periodontal pathogens. The aim of this work was to evaluate the minimal inhibitory concentration (MIC) of minocycline on superinfecting microorganisms isolated from the periodontal pocket and the oral cavity of individuals with chronic periodontitis. Isolates of Enterobacteriaceae (n = 25), Staphylococcus spp. (n = 25), Pseudomonas aeruginosa (n = 9) and Candida spp. (n = 25) were included in the study. Minimal inhibitory concentrations (MIC) of minocycline were determined using the Müeller-Hinton agar dilution method. Staphylococcus spp. isolates were the most sensitive to minocycline with a MIC of 8 µg/mL, followed by Enterobacteriaceae with a MIC of 16 µg/mL. The concentration of 16 µg/mL inhibited 96% of Candida spp. isolates. The MIC for 88.8% of the isolates of Pseudomonas aeruginosa was 128 µg/mL. A concentration of 1,000 µg/mL was not enough to inhibit 100% of the tested isolates.

BACKGROUND: Superoxide dismutase (SOD), an antioxidant acting against superoxide (oxygen radical, O2.-), it is released in inflammatory pathways and causes connective tissue breakdown. Increased SOD activity in inflamed gingiva may indicate increased O2.-radical generation by neutrophils and other inflammatory cells at the diseased site. The aim of the study was to evaluate the effects of non-surgical periodontal therapy (NSPT) on SOD levels in gingival tissues of chronic periodontitis patients.METHODS: Forty subjects: 20 periodontally healthy (Control) and 20 chronic periodontitis (Test); age range 24–55 years were recruited. Gingival tissue samples were collected by excising the inner lining of the periodontal pocket at baseline (prior to non-surgical periodontal therapy) and 2 months post therapy. In controls, tissue samples were obtained immediately after tooth extraction scheduled for orthodontic reasons. Clinical parameters included probing depth, clinical attachment level, gingival index, bleeding index, plaque index. SOD activities were assessed spectrophotometrically at baseline and 2 months post NSPT, results were analysed statistically.RESULTS: At baseline, patients with chronic periodontitis had higher mean SOD activity (2.73 ± 1.36) than the control subjects (1.12 ± 1.13) withp= 0.00003 (p< 0.05). At 2 months post NSPT median SOD level (1.00) had come close to median SOD value of control group (0.85);p= 0.99 (p> 0.05). The resolution of inflammation with successful NSPT resulted in decreased SOD levels as in control group. Clinical parameters in patients with chronic periodontitis showed a significant improvement 2 months post NSPT (p< 0.05).CONCLUSION: Non-surgical periodontal therapy significantly improves the clinical parameters and restores previously increased SOD levels to normal in chronic periodontitis patients.

Background. Albumin is a protein whose serum levels decrease in inflammatory conditions such as periodontal diseases. This study was undertaken to evaluate changes in serum albumin levels in patients with and without periodontal diseases prior and subsequent to non-surgical periodontal treatment and its relationship with clinical parameters of periodontal disease.Methods. Twenty patients diagnosed as having chronic periodontitis and 20 periodontally healthy subjects, referring to Tabriz Faculty of Dentistry, were selected. Serum albumin levels and clinical variables of periodontal disease (probing pocket depth, gingival index, bleeding index, clinical attachment level and plaque index) were determined before treatment and three months subsequent to non-surgical periodontal treatment. Data were subjected to descriptive statistical analyses (mean ± SD). Serum levels of albumin and clinical parameters were compared between the two groups with independent-samples t-test. Paired-samples t-test was applied to compare the variables before and after treatment in the case group. Statistical significance was defined at P<0.05.Results. The mean serum albumin level of chronic periodontitis patients (3.62±0.11 mg/dL) exhibited a significantly lower value compared to subjects who were periodontally healthy (4.17±0.29 mg/dL), with the serum albumin levels increasing significantly three months postoperatively (3.78±0.33 mg/dL), approaching the level in subjects who were periodontally healthy (P<0.05).Conclusion. Decreases and increases in serum albumin levels under the effect of periodontal disease and its treatment indi-cated an inverse relationship between the albumin levels of serum and chronic periodontitis.
