Active clinical trials for "Periodontitis"

Pain after periodontal surgical procedures is a common manifestation. The perception of pain is highly subjective and varies substantially among individuals. Many factors affect pain perception, such as the nature, duration, and extent of the surgery and psychological aspects (e.g., stress and anxiety). Pain after periodontal surgery is an example of acute dental pain of mild to moderate severity. Non-steroidal anti-inflammatory drugs (NSAIDs) have a significant advantage in the control of pain after periodontal or oral surgical procedures. Diclofenac is a powerful anti-inflammatory and analgesic drug that is well suited for local use in the oral cavity. Diclofenac competes with arachidonic acid in a dose dependent manner for binding with platelet COX. This results in decreased production of PG and thus reduces inflammation, swelling and pain. As Diclofenac associated with many adverse effects, like gastric irritability, nausea, headache, dizziness. Undesirable effects may be minimized by using the lowest effective dose for the shortest duration necessary to control symptoms. As many of clinical trials have suggested Diclofeanc 50 mg alleviates the postoperative pain. So main aim of the study was to evaluate the effectiveness of low dose Diclofenac(25mg) in reducing the post operative pain after periodontal flap surgeries. Thus comparing the effects of low dose Diclofenac and Diclofenac 50mg for reducing post-operative pain.

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.

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.

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.

Background: platelet concentrate could enhance growth factors (GF) crevicular fluid levels which might be crucial to proper tissue repair and wound healing. However, the open usually contaminated nature of periodontal defects could affect negatively GF availability and activity. To test this assumption, this study was designed to evaluate levels of VEGF and PDGF-BB in gingival crevicular fluid (GCF) during the early stages of healing of localized intrabony defects treated with platelet rich in growth factor (PRGF) and platelet rich fibrin (PRF) as compared with xenograft defect filling control. Methods: Thirty non-smoking patients with severe chronic periodontitis participated in this prospective, randomized and single blinded trial. Each patient contributed one interproximal defect that was randomly assigned to the bone substitute grafting control (n=10) G1, experimental PRGF (n=10) G2 and PRF (n=10) G3. Plaque index, gingival index, probing depth (PD), clinical attachment level (CAL) and the intrabony depth of the defect (IBD) were measured at baseline for patient enrollment. Gingival crevicular fluid (GCF) samples were collected on days 1 and 3, 7, 14, 21, and 30 days after therapy. The primary outcome variable was the change in VEGF and PDGF-BB levels for sites treated by PRGF and PRF compared to that of the xenograft treated cases.

Periodontal Diseases are considered the sixth complication of Diabetes Mellitus (DM). This close relationship between both diseases is characterized by mutual influence. The presence of DM might impair prognosis of diverse dental treatments due to its inflammatory nature, negative influence on wound healing, on bone biology, and the establishment of infections. Consequently, knowledge of new dental therapies and the biology of dental treatments for chronic periodontitis in diabetic patients can enhance quality of life and make these treatments more adequate for this common profile of patients.

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.

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.

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.

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.
