Active clinical trials for "Periodontitis"

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.

Aim: To compare the clinical antimicrobial and adverse effects of irrigation with Sodium Hypochlorite (NaOCl) 0.5% versus NaOCl 3% during root canal treatment. Methodology: Consecutive patients referred to a specialist clinic of endodontics are randomly assigned to have the root canal treatment performed with a concomitant irrigation either with a buffered 0.5 % NaOCl (Dakin's solution) or 3 % NaOCl. Teeth with vital or necrotic pulps and retreatment cases were included. Root canal treatment procedures varied but followed the routines of the Specialist Clinic of Endodontics, Public Dental Health, Gothenburg, Sweden. Immediately before the root canal filling a microbial sample is taken from the operative field and the root canal. The bacterial samples were processed at the laboratory as outlined by Möller (1966). After each visit each patient was instructed to fill in a questionnaire and assess his or her post-operative pain on a visual analogue scale (VAS), with endpoints 0= "no pain" and 10= "worst imaginable pain", for seven consecutive days. The Fischer's exact test was used for statistical analyses of the differences in outcome between the groups.

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.

ABSTRACT: Background: Platelet-rich fibrin (PRF) is a second-generation platelet concentrate which releases various growth factors that promote tissue regeneration. Metformin (MF), a member of biguanide group has been shown to facilitate osteoblast differentiation and thus may exhibit a favourable effect on alveolar bone . Current study was designed to evaluate the combined efficacy of PRF and 1% MF gel with open flap debridement (OFD) in treatment of intrabony defects in chronic periodontitis (CP) subjects. Methods: One hundred and twenty subjects with single defects were categorized into four treatment groups: OFD alone, OFD with PRF, OFD with 1% MF and OFD + PRF+1% MF. Clinical parameters like site specific plaque index (PI), modified sulcus bleeding index (mSBI), probing depth (PD), relative attachment level (RAL) and gingival marginal level (GML) were recorded at baseline before surgery and 9 months post-operatively. Percentage radiographic intra-bony defect depth reduction was evaluated using computer-aided software at baseline and 9 months.

The aim of this study is to evaluate the effect of hyaluronic acid in the surgical treatment of periodontal pockets in people with gum disease. This research consists of clinical and radiographic studies. Participants should have symmetric periodontal pockets in the upper or lower jaw. Participants will be treated surgically using hyaluronic acid on one side of the jaw. Clinical indexes and radiographic cone-beam computed tomographic (CBCT) images will be taken for each participant before surgical treatment and 12 months after surgical treatment.

Randomized controlled clinical trials have demonstrated that the use of amoxicillin (AMX) and metronidazole (MTZ) as adjuncts to mechanical therapy improves the clinical and microbiological outcomes of scaling and root planing (SRP) in non-smokers and smokers with ChP. However, the effects of this antibiotic protocol have not been directly compared in non-smokers and smokers. Therefore, the aim of this study will be to compare the clinical and microbiological effects of the adjunctive use of MTZ+AMX to SRP in smokers and non-smokers subjects with chronic periodontitis (ChP). It was hypothesized that non-smokers would benefit better from this combination of therapies than the smokers.

The investigators primary objective in this clinical intervention study, therefore, was to explore the impact of omega-3 PUFAs in conjunction with scaling and root planing on salivary markers (in patients with chronic periodontitis.

The aim of this study is to provide evidence on the clinical efficacy of SmartMouth Advanced Clinical Formula mouthrinse in comparison to the efficacy of 0.12% chlorhexidine mouthrinse and a placebo mouthrinse. The placebo will be provided by the sponsor and will be identical to SmartMouth ACF (Advanced Clinical Formula), except it will not contain cetylpyridinium chloride, zinc chloride and sodium chlorite. The primary outcomes include measures of plaque and gingivitis. Secondary outcomes include evaluation of tooth discoloration, taste perception, malodor and calculus.
