[Ab] Abstract:BACKGROUND: The aim of the study was to explore the influence of periodontitis and scaling and root planning on insulin resistance and hepatic CD36 in obese rats with periodontitis. METHODS: Thirty-two specific pathogen free Sprague-Dawley rats were randomly divided into four groups of eight animals each as follows: healthy rats (healthy group), obese rats (obesity group), obese rats with periodontitis (non-therapy group), and obese rats with periodontitis who underwent periodontal scaling and root planning (SRP) (therapy group). Rats were fed with a high-fat diet for 16 weeks to build an obesity model. Periodontal inflammation was induced by performing periodontal ligation with Porphyromonas gingivalis. The tissue around the maxillary 2nd molars, bilaterally, were collected. The periodontal attachment level (from the cementoenamel junction to the bottom of the periodontal pocket) of the second molars was measured in all groups. All rats were subjected to fasting blood glucose, insulin, and serum C-reactive protein tests (CRP). Insulin resistance was evaluated by homeostasis model assessment of insulin resistance (HOMA-IR), oral glucose tolerance test (OGTT), and area under the curve (AUC). The liver was excised to detect intrahepatic free fatty acid (FFA) levels and pathological observation. Real-time quantification PCR, western blot, and immunohistochemistry were applied to detect hepatic CD36 expression. RESULTS: Compared with the obesity group, HOMA-IR, AUC, intrahepatic FFA, and protein expression, and mRNA levels of hepatic CD36 in the non-therapy group were significantly increased (P < 0.05). HOMA-IR, AUC, CRP, protein expression, and mRNA levels of hepatic CD36 were all significantly decreased (P < 0.05) 2-weeks after SRP. CONCLUSIONS: Periodontitis increases insulin resistance while scaling and root planning could improve insulin resistance. Hepatic CD36 regulation may be considered a potential mechanism for this phenomenon. This article is protected by copyright. All rights reserved.

[Ti] Title:Shift in the subgingival microbiome following scaling and root planing in generalized aggressive periodontitis.

[Ab] Abstract:AIM: To investigate the shift in the subgingival microbiota under scaling and root planing (SRP) in patients with generalized aggressive periodontitis (GAgP). MATERIALS AND METHODS: After undergoing supragingival scaling, 12 individuals with GAgP were enrolled in this longitudinal study. Full-mouth SRP was accomplished in 3 weeks and re-evaluated 6 weeks later. Pooled subgingival samples (posterior-mesial, posterior-buccal, anterior-mesial, and anterior-buccal) were obtained from each patient before SRP (pre-treatment group) and at the time of re-evaluation (post-treatment group). 16S rRNA PCR products were generated and sequenced after DNA isolation. RESULTS: Under SRP, the diversity of the subgingival community was consistent, whereas genus-level biomarkers transformed from Porphyromonas, Treponema, and Fretibacterium to Actinomyces, Streptococcus, and Haemophilus. In a network analysis, pathogen-related and non-pathogen-related components were identified in both the pre- and post-treatment groups; the pathogen component was dramatically augmented, while the non-pathogen component shrank after treatment. Hubs were also distributed in both components pre-treatment and were confined to the pathogen component post-treatment. CONCLUSIONS: Scaling and root planing decreased periodontal pathogens in the subgingival microbiota of patients with GAgP. However, the shift in the microbiota composition was characterized by the expansion of pathogen-related components and the contraction of non-pathogen-related components 6 weeks after SRP.

[Ab] Abstract:OBJECTIVES: To evaluate the effects of systemic antibiotics as adjuncts to nonsurgical periodontal treatment (NSPT), as opposed to using NSPT alone, on periodontal clinical parameters of diabetic patients with periodontitis. MATERIALS AND METHODS: Randomised controlled trials with a follow-up of 3 months or more, assessing the effects of NSPT in combination with antibiotics, in diabetic patients with periodontitis were included. Trials published up to August 2016 were identified from MEDLINE, EMBASE and LILACS databases. Meta-analyses were conducted to determine changes in clinical attachment level (CAL), probing pocket depth (PPD), bleeding on probing (BOP) and gingival index (GI). Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in this review. RESULTS: Of the 164 papers potentially admissible to this systematic review, 15 articles on 11 randomised clinical trials were considered as eligible. The results of the meta-analyses presented a modest additional benefit of 0.14 mm (95% confidence interval: 0.08-0.20) in reducing PPD but no further benefit in CAL gain. CONCLUSION: When the data for all antibiotic protocols were considered together for the treatment of periodontitis patients with DM, a significant, albeit small, reduction of PPD and no improvement in CAL gain was observed. When the antibiotic protocols were analysed separately, the combination of amoxicillin plus metronidazole yielded the best results for PPD.

[Ti] Title:Scanning Electron Microscopy Evaluation of Root Surfaces After Instrumentation With Two Piezoelectric Devices.

[La] Language:eng
[Ab] Abstract:Scanning electron microscopy evaluation of root surfaces after ultrasonic instrumentation was performed with 2 different metallic tips on piezoelectric devices. Fresh extracted teeth were collected for experimental observation and randomly divided into 2 groups: Test Group, where the root surfaces were treated using an iron, rough, double nano-structural coated (T-Black), corindone-treated tip, and Control Group where the root surfaces were treated with a conventional iron smooth tip. A scanning electronic microscope analysis was performed and the surface roughness and the amount of residual debris were evaluated. Descriptive and inferential statistics were performed. Twenty specimens were analyzed, 10 per group and a total of 21.4 × 10 µm has been observed. On treated area percentage of debris after ultrasonic scaling in Test Group was 1.9 ±â€Š1.8%, while in Control Group it was 5.7 ±â€Š4.3%. Within the limits of the study, it seems that the efficacy of the novel iron, rough, double nano-structural coated (T-Black), corindone-treated structure tip showed greater performance in terms of root surface debridement than the conventional iron smooth tip. The possibility to use a single tool (ultrasonic device with a specific tip) for the root planing procedure within the nonsurgical mechanical therapy may represent a significant advantage for the clinicians. The tested novel tip seems to be able to show the requested ideal characteristics. However, further clinical studies are needed to demonstrate the in vitro results.

[La] Language:eng
[Ab] Abstract:BACKGROUND: To assess the impact of scaling and root planing (SRP) with and without adjunct photodynamic therapy (PDT) in the treatment of periodontal disease (PD) in hyperglycemic patients. METHODS: Databases (MEDLINE, EMBASE; and CENTRAL) were searched up to December 2017. The addressed PICO question was: "What is the effectiveness of adjunctive PDT to non-surgical periodontal treatment by means of clinical periodontal and glycemic parameters in hyperglycemic patients?" RESULTS: Four clinical trials and 1 experimental study were included. Energy fluence, power output, power density and duration of irradiation were 2.79 joules per square centimeters (J cm ), 150 milliwatts (mW), 428 milliwatts per square centimeters (mW cm ) and 133 seconds (s) respectively. All studies reporting clinical periodontal and metabolic parameters, showed that aPDT was effective in the treatment of periodontal inflammation in hyperglycemic patients at follow-up. When compared with SRP alone, none of the studies showed additional benefits of PDT as compared to SRP alone at follow up. Three studies showed no influence of SRP with or without aPDT on HbA1c levels. One study showed a significant reduction of HbA1c levels in adjunctive aPDT as compared to SRP alone at follow-up. CONCLUSION: It remains debatable whether adjunctive PDT as compared to SRP is effective in the treatment of periodontal inflammation and reduction of HbA1c levels in hyperglycemic patients.

[Ab] Abstract:BACKGROUND: The erbium-doped yttrium, aluminum, and garnet (Er:YAG) laser is thought to be the most promising laser for periodontal treatment; however, its application is still under consideration. The aim of this study was to compare Er:YAG laser monotherapy with conventional scaling and root planing (SRP) for chronic periodontitis using clinical parameters, the detection rate of periodontal pathogens, and the calprotectin level in gingival crevicular fluid. METHODS: Twenty-seven participants with moderate-to-advanced chronic periodontitis were included. In a split-mouth design, the 2 half-mouths of each participant were randomly assigned to Er:YAG laser or SRP (combination of ultrasonic and manual instruments) treatment. Clinical parameters were recorded at baseline, 6 weeks, and 3 and 6 months after treatment. At the same time points, gingival crevicular fluid was collected to analyze the detection rate of 6 periodontal pathogens by polymerase chain reaction and the levels of calprotectin by enzyme-linked immunosorbent assay. RESULTS: Both treatment groups showed significant reductions in probing depth (PD), bleeding index (BI), and clinical attachment level (CAL) from baseline to 6 months. For sites with 4 mm ≤ PD ≤ 6 mm at baseline, SRP resulted in a greater reduction in PD and CAL than Er:YAG laser treatment, and the difference remained at 6 months post-treatment (P = .01 and P < .01, respectively). For sites with PD ≥7 mm at baseline, the clinical parameters showed similar results between the 2 groups. SRP resulted in a lower detection rate of Porphyromonas gingivalis at 6 months post-treatment. The levels of calprotectin were significantly decreased from baseline to 6 months in both groups, without a significant difference between the groups. CONCLUSION: For mild pockets, conventional SRP may still be the preferred choice. For deep pockets, Er:YAG laser treatment could be an effective alternative. Studies are needed to explore more advanced instruments and new application methods for the Er:YAG laser for periodontal treatment in deep pockets.

[Ab] Abstract:In the present study, the impact of scaling and root planing (SRP) on gingival crevicular fluid (GCF) cytokine/chemokine levels in smokers with chronic periodontitis was assessed. The PICO (population, intervention, comparison, outcome) question was: In smokers with chronic periodontitis (population), what is the effect of SRP (intervention) in comparison to SRP in non-smokers with chronic periodontitis (comparison) on the GCF cytokine/chemokine level (outcome)? Indexed databases were searched up to September 2017. Of 4330 titles, nine studies reporting the levels of 13 different cytokines/chemokines were included. Eight studies had a moderate risk of bias, while one study had a high risk of bias. Almost all cytokines/chemokines were pro-inflammatory cytokines. Five cytokines/chemokines studied in four clinical studies were decreased in the smoker-chronic periodontitis group following SRP. One study observed that the GCF levels of interleukin-17 increased, while anti-inflammatory osteoprotegerin was reduced in both the SCP and non-smoker-chronic periodontitis groups at follow up. However, the majority of cytokines/chemokines did not change in the SCP groups at follow up. The current weight of evidence is not sufficient to prove that SRP has an impact on GCF cytokine/chemokine profile in smokers with chronic periodontitis. Evaluation of wide panels of pro-inflammatory cytokines/chemokines related to collagen degradation and alveolar bone destruction in future studies are warranted.

[La] Language:eng
[Ab] Abstract:OBJECTIVES: The aim of this study is to evaluate the effect of operators experience and skill on treatment results of initial non-surgical periodontal therapy. MATERIALS AND METHODS: Initial periodontal treatment was carried out by either second-year periodontal residents (PR) or last year dental students (DS). From the treatment records of patients in each group, plaque and bleeding indices, and pocket depth (PD) at baseline and at re-evaluation were collected retrospectively on each tooth at six locations. Data were separated according to tooth type, area, and probing depth categories, sub-grouped to 1-3, 4-5, and ≥ 6 mm. RESULTS: Fifty and 49 records of DS and PR patients, accordingly, were analyzed. Initial periodontal treatment improved patient compliance in both groups and reduced signs of inflammation with significantly superior results in the PR group. Significant change in percentage of pockets was recorded in each category. The increase in percentage of sites with PD 1-3 mm and decrease in percentage of PD ≥ 6 mm pockets was significantly (p ≤ 0.001) superior in patients treated by PR. Percentage of 4-5 mm pockets was significantly reduced in both groups (p ≤ 0.01), with a significantly greater reduction in the mandibular molar and anterior teeth in the PR group. CONCLUSIONS: Experience and skill significantly affect the outcome of non-surgical periodontal therapy, with more positive improvement in patient compliance and clinical parameters when performed by a more qualified operator. CLINICAL RELEVANCE: Improvement of operator skills may decrease the number of residual pockets and increase patient compliance following non-surgical periodontal treatment.

[Ab] Abstract:BACKGROUND: Tumor necrosis factor alpha (TNF-α) is an inflammatory mediator whose levels are increased in the gingival crevicular fluid and blood serum in the case of chronic periodontitis. OBJECTIVES: The aim of this study was to determine the effect of vector ultrasonic system (VUS) on the levels of TNF-α in gingival crevicular fluid (GCF) and the clinical parameters in patients with chronic periodontitis. MATERIAL AND METHODS: The study protocol was conducted using split-mouth design in 30 patients with chronic periodontitis. VUS and scaling and root planing (S/RP) were applied separately to 2 quadrants, including the upper and the lower jaws. At baseline and after 6 months, clinical parameters including plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL) were recorded, and concentrations of TNF-α in GCF were determined by enzyme-linked immunosorbent assay (ELISA). Intergroup comparisons were evaluated by the independent Students' t-test, and the Pearson correlation was used to determine the relationship between parameters. The level of significance was set at 5%. RESULTS: Both treatment modalities provided statistically significant improvements in clinical periodontal parameters and TNF-α levels after 6 months (p < 0.05). Also, there were no significant correlations between the TNF-α levels in GCF and the clinical parameters in both treatment group at baseline and at the end of 6 months period (p > 0.05). CONCLUSIONS: The use of the vector ultrasonic system in the non-surgical treatment of chronic periodontitis presents beneficial improvements for the clinical attachment level and the probing pocket depth as well as TNF-α levels in GCF.

[Cp] Country of publication:Australia
[La] Language:eng
[Ab] Abstract:AIM: This study compares diamond burs and curettes by clinical, microbiological, biochemical, scanning electron microscopic parameters and treatment time data in the non-surgical periodontal treatment of patients with chronic periodontitis. METHODS: Two quadrants of each of the 12 patients received root planing with diamond burs whereas other 2 quadrants were treated with curettes. Clinical periodontal measurements were recorded at baseline and then 1, 3, 6 months after completion of non-surgical periodontal treatment. Subgingival plaque, gingival crevicular fluid samples were obtained at baseline and 1-month control. Twenty-one hopeless teeth received root planing with diamond burs or curettes or no treatment at all and then extracted for microscopic evaluations. RESULTS: Clinical periodontal parameters improved similarly with both treatment modalities. Microbiological analyses revealed similar findings for the bacterial load (16S gene copy numbers), ratio of each bacterium to the total bacterial count at baseline, 1-month control. Cytokine levels in the gingival crevicular fluid samples exhibited differences between the two treatments. Scanning electron microscopic analyses indicated that diamond burs were better in terms of calculus removal, loss of tooth substance indices, but roughness index values were better for curettes. CONCLUSION: As a conclusion, diamond burs provide findings comparable with curettes in root planing. This article is protected by copyright. All rights reserved.
