Active clinical trials for "Chronic Periodontitis"

The aim of this study is to verify the efficacy of Photodynamic Therapy (PDT) as an adjunct to non-surgical treatment of chronic periodontitis by assessing clinical and microbiological and immunological parameters. This is a randomized, controlled, double-blind, parallel clinical trial. Thirty eight patients with chronic periodontitis will receive conventional periodontal treatment. After eight weeks, patients will be re-evaluated and sites with residual pockets (PD ≥ 5 mm ) will be selected as experimental sites, and will be allocated to test and control group randomly. The test group will receive the application of PDT and the control group will receive sham procedure. The clinical parameters will be evaluated at baseline, 3, 6 and 12 months after treatment. Subgingival plaque will be collected before PDT, a week after, 3, 6 and 12 months later. The microbiological evaluation will detect and quantify periodontal pathogens such as Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Aggregatibacter actinomycetencomitans with real time-PCR. During follow-up, patients will receive periodontal maintenance every 3 months, as well as the application of PDT or sham

This study aims to evaluate clinically the efficacy of flurbiprofen gel in comparison to Aloe Vera gel as adjunctive to SRP in the reduction of periodontal pockets in patients with chronic periodontitis in smoking patients. All patients will receive SRP prior to treatment. Group 1: one site will receive flurbiprofen while the contralateral site will receive a placebo Group 2: one site will receive aloe vera while the contralateral site will receive a placebo Group 3: one site will receive flurbiprofen while the contralateral site will receive aloe vera Researchers will compare the inter and intra-groups differences to check if there's a variation in the periodontal parameters measured.

The aim of the study is to evaluate the effectiveness of Hypochlorous Acid and Chlorhexidine as postsurgical antimicrobial agents in the treatment of severe chronic periodontal disease. The selected patients will be randomly divided into two groups of 16 each. Subjects in group I will undergo scaling and surgical root planing and will use mouthrinse with 0.05% HOCl for 7 days, after this they will mouthwash with 0.025% HOCl until day 21 and Subjects in group II will undergo scaling and surgical root planing followed by a rinse with CHX 0.2% for 7 days, after this they will mouthwash with 0.12% CHX until day 21. Null Hypothesis: There are no significant differences between hypochlorous acid and chlorhexidine in reducing plaque formation at 7, 21 and 90 days of evaluation. There are no significant differences between HOCl and CHX in the elimination or reduction of periodontopathogenic microorganisms at 7, 21 and 90 days. Alternative hypotheses: There are significant differences between hypochlorous acid and chlorhexidine in reducing plaque formation at 7, 21 and 90 days of evaluation. There are significant differences between HOCl and CHX in the elimination or reduction of periodontopathogenic microorganisms at 7, 21 and 90 days.

The present study aimed to evaluate the effects of enamel matrix derivatives either alone or combined with autogenous bone graft applied to intrabony defects in chronic periodontitis patients on clinical/radiographic parameters and gingival crevicular fluid transforming growth factor-β1 level and, to compare with open flap debridement. Our hypothesis is to test whether the use of autogenous bone graft and enamel matrix derivative combination in the treatment of intrabony periodontal defects enhance the clinical, radiographic and biochemical parameters in comparison to the use of open flap debridement alone.

Metformin (MF), a biguanide group of anti-diabetic drug has been shown to enhance osteoblasts differentiation and inhibit osteoclast differentiation in vitro, thus may exhibit a favourable effect on alveolar bone. The present study aims to explore the efficacy of 1% MF gel as a local drug delivery system in adjunct to scaling and root planing (SRP) for the treatment of Class II furcation defects in comparison with placebo gel.

Periodontitis is initiated by microbial biofilm but its progression is mediated by an abnormal host response to biofilm microorganisms. In a myriad of possible mechanisms that cause periodontal tissue destruction reactive oxygen species (ROS) play an important role. Imbalance between antioxidant defense system of body and ROS lead to a deleterious situation called oxidative stress. Superoxide dismutase (SOD) is the key enzyme of body's antioxidant defense system whereas malondialdehyde (MDA) is product of lipid peroxidation due to ROS. Free radicals and ROS have short half lives in vivo of 10-6 to 10-9 seconds. Hence measurement of ROS is done by measuring the concentration of biomarkers of tissue destruction. For treating periodontal disease, conventional mechanical therapy comprising of scaling and root planing (SRP) along with timely maintenance has been a gold standard and any other therapy considered for treating periodontitis should always be used as an adjunctive and never in lieu of it. Curcumin, a hydrophobic polyphenol, is a principal active constituent of turmeric. Mechanism of action of curcumin is twofold-its role as a strong antioxidant and as a strong antibacterial. Its analgesic, anti-inflammatory and antiseptic properties offer additional benefits.Periodontitis is a chronic disease of oral cavity accompanied by increased oxidative stress. Therefore the clinical application of a natural antioxidant in the form of curcuma longa can be beneficial in reducing oxidative stress and as an adjuvant in treatment of chronic periodontitis.

Background: Furcation is the bifurcation or trifurcation of a multirooted tooth. It is an area of complex anatomic morphology difficult to debride by routine periodontal instrumentation. Multiple approaches have been used in an effort to treat the furcation Choukroun's platelet-rich fibrin (PRF), a second generation platelet concentrate has biochemical components which have well known synergetic effects on healing processes. The present study was conducted to evaluate the effectiveness of autologous platelet-rich fibrin (PRF) in the treatment of mandibular molar Grade 2 furcation defects in comparison to allograft and guided tissue regeneration (GTR) membrane.

Summary The aim of this study is to evaluate through clinical, microbiological and immunological parameters using PLGA microspheres (lactic-co-glycolic acid polyacid) containing doxycycline in periodontal therapy in smokers with chronic periodontitis. For this study, 40 patients will be selected, with an average age between 30 and 59 years old of both genders (male and female), who spontaneously seek the clinic graduate of the Piracicaba Dental School -FOP / UNICAMP, and exhibiting at least four bleeding sites, including 2 sites with a probing depth (PD) between 5 and 6 mm and two sites PS ≥7 mm in uniradiculares teeth. Patients should have a minimum of 20 teeth. Will be excluded from relevant systemic disease carriers or antibiotics used in the 6 months preceding the study. All patients will receive oral hygiene instruction and will undergo a pre-treatment, which will be held supragingival sweeps and removal of plaque retentive factors. Patients will be divided into 2 groups (DB + DOX: Debridement + Doxycycline, test group and DB: only debridement, control group) of 20 patients who will receive the following treatments: periodontal debridement ultrasound for 45 minutes associated with the local administration of 1 mg microspheres containing doxycycline, or just mechanical debridement, for each selected site. Will be assessed the following clinical parameters: gingival index (GI) Plaque Index (PI), Bleeding on Probing (BOP), Position of the gingival margin (PGM), Probing Depth (PD) and Relative Clinical Attachment Level (RCAL). The microbiological evaluation will be made by means of polymerase chain reaction - real time ( "real time" - PCR) to detect bacteria: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans and Prevotella intermedia. The enzyme immunoassay (LUMINEXMAGPIX) allow the detection of cytokine levels of GM-CSF, INF-γ, IL-10, IL-12, IL-13, IL-1β, IL-4, IL-6, IL-8 and TNF-α. The analysis of the proteolytic enzyme activity is accomplished by using zymography to assess MMP-8 and MMP-9. The described parameters will be evaluated at baseline, 45 and 90 days after the initial visit. The results are compared statistically by analysis of variance with repeated measures with 5% significance level.

The purpose of the present study was to investigate the efficacy of autologous Platelet rich fibrin (PRF) or PRF and Simvastatin (SMV) with open flap debridement (OFD) in the treatment of three wall intrabony defects in comparison to OFD alone.
