Active clinical trials for "Periodontitis"

Periodontitis is a chronic inflammatory disease characterized by both dysbiosis of oral microbiota and proinflammatory events involving both cells and mediators from innate and adaptive immunity. These events lead to chronic inflammation of periodontal soft and hard tissues sharing many features with other chronic inflammatory diseases. These events lead to chronic inflammation of periodontal soft and hard tissues sharing many features with other chronic inflammatory diseases. Chronic inflammation is driven by various mediators, of which a significant part is attributed to the interactions within cytokine networks. While proinflammatory cytokines, including interleukin (IL) -1α, IL-1β, TNF-α, IL-6, and IL-17, contribute to acute and chronic inflammation and tissue injury, a second group with antagonist effects is formed by cytokines such as IL-10

A randomised cross-over study comparing two methods of local anaesthesia for patients diagnosed with periodontitis undergoing scaling and root planning. 40 patients will be included in the study, which aims to demonstrate that the effect of a bupivacaine lozenge is non-inferior to lidocaine-adrenalin injections.

This study will evaluate whether use of antidepressants can reduce gingival inflammation in patients with periodontal (gum) disease.

This prospective parallel, double-blind, four-arm randomised controlled clinical study is planned to assess the difference in the level of the inflammatory biomarkers expressed following the placement of the first dental implant in patients with history of periodontitis (successfully treated) and healthy controls without the disease, during implant osseointegration period. The subjects in both groups will also be randomised to receive one of the two types of implants provided which have different surface treatment.

This study will determine whether the supplemental use of chemical pocket disinfection with scaling and root planing is more effective than scaling and root planing alone in clinically reducing periodontal probing depth (PD), reducing bleeding on probing (BOP), and gaining clinical attachment level (CAL). It also will assess whether chemical pocket disinfection with scaling and root planing will have an effect on biomarkers of inflammation.

Periodontitis is a highly prevalent chronic inflammatory disease that is characterized by loss of the periodontal ligament and alveolar bone, and is a major cause of tooth loss. Results from clinical and epidemiological studies have suggested that periodontitis and tooth loss are more prevalent in individuals with rheumatoid arthritis (RA). There is evidence to suggest that periodontitis could indeed be a causal factor in the initiation and maintenance of the autoimmune inflammatory response that occurs in RA. If so, chronic periodontitis might represent an important modifiable risk factor for RA. However, to date longitudinal studies on the effect of periodontitis on disease progression in RA are lacking. The aim of the present study is to assess the periodontal status of patients enrolled in an established longitudinal cohort of RA patients. These data will then be analysed to evaluate whether or not periodontal inflammation is related to parameters of rheumatoid arthritis.

Randomised, controlled, clinical study to compare the effect of the combination of bone ceramic and enamel matrix proteins (test) versus autogenous bone graft alone (control) in the treatment of deep-wide intrabony defects

Diabetes and Periodontitis are both prevalent diseases affecting millions of Americans. Periodontitis is prevalent among Diabetics. Furthermore, Periodontitis and associated inflammation can increase insulin resistance in Diabetics and worsens the condition. Hyperbaric Oxygen Therapy (HBOT) has the potential to improve periodontal treatment outcome in poorly controlled diabetics. The study will compare periodontal treatment (SRP) outcome between 2 main diabetic type 2 patient groups receiving medical care treatment: either Conventional Wound Therapies (CWC) with or without adjunctive Hyperbaric Oxygen Therapy at LLU Health. 24 poorly controlled diabetic mellitus (DM) type 2 subjects (HbA1c =>7%) with Periodontitis will be assigned into the study arms HBO therapy and Non HBO therapy, based on their medical needs. For all subjects demographic data (age, gender, ethnicity, smoking history, alcohol use history, BMI, current medication list) and oral health habits will be obtained. Blood samples for HbA1c determinations, clinical periodontal measurements (plaque index, probing measurements including pocket depth, attachment levels, gingival index and bleeding-on-probing) and subgingival microbial samples will be obtained at baseline and end of the study. Subgingival microbial samples will be collected from three randomly selected sites and analyzed for detection of about 300 of the most prevalent oral bacterial species. Differences in periodontal clinical outcomes and bacterial profiles will be identified utilizing ANCOVA (Analysis of Covariance).

Periodontitis, an infectious disease that affects the tooth-supporting tissues and shows a wide range of clinical, microbiological, and immunological manifestations, is associated with and probably caused by dynamic interaction among infectious agents, host immune responses, hazardous environmental exposure and genetic propensity. Bacteria are necessary for the disease to appear, but are not sufficient and do not account for all cases of periodontitis. According to one survey in the USA, chronic periodontitis affects approximately 46% of the adult population, with an even higher prevalence among the elderly. This prevalence refers to the cohort of young adults according to the WHO, with ages ranging from 35 to 44 years. Forms of periodontitis that appear at younger ages (before the age of 30 years), and that have other characteristics in addition to age, are known as aggressive periodontitis. The prevalence of this disorder ranges from 0.2% in Caucasians to 2.6% in Afro-Americans. The microbiota of the human oral mucosa together with other anatomical locations in the body constitute the human microbiome. The equilibrium between these organisms and the host response plays a fundamental role in human biology, both in health maintenance and in the appearance of disease. Unfavorable alterations in the composition of the microbiota are termed dysbiosis. Antiseptics and antibiotics such as Chlorhexidine or Metronidazole, are delivered locally as an adjunct to scaling and root planing procedures, in order to eradicate the subgingival microbes, hence creating a healthy subgingival environment. However, the results presented in the literature are inconclusive. There is a need for further clinical trials with strict methodological criteria for allowing a more precise assessment of the efficacy of local antimicrobials in the treatment of chronic periodontitis. Recently, there has been renewed interest in the application of natural products. Several natural products and herbs have claimed to have better properties and less side effects than chemical agents for irrigation. The use of natural extracts and essential oils as an irrigation agent for ultrasonic instrumentation has shown to promote slight adjunctive effect compared to chlorhexidine or water. In other study, natural extract showed a greater improvement compared to controls in patients with a more severe degree of periodontitis. However, in other studies this pocket reduction and clinical attachment gain were no significant when compared to water. Natural products have also been tested in forms of oral spray, and have shown to be effective against common oral pathogens without significant cytotoxicity in an in vitro study. Thus, it has the potential to prevent the infections and may serve as adjunctive treatment to conventional therapy. They claim to have the same or even more anti-microbial effect and anti-inflammatory effect without adding any chemicals. But still there is no adequate scientific evidence to support this hypothesis. This study aims to test the effect as an adjutant to therapy of a nutraceutical composed of several plant extracts in patients with periodontitis and different levels of risk for metabolic syndrome. Specifically: The response of periodontal clinical variables to non-surgical periodontal treatment in patients treated with the extract, compared to controls. The effect on local inflammatory markers, in patients treated with the extract compared to controls. The modifier effect of metabolic syndrome-related variables in the treatment outcomes of the patients treated with the extract compared to controls. Hypothesis: The application of the plant extract would act as an anti-inflammatory agent, contributing to better treatment outcomes of periodontitis, in terms of clinical and biochemical variables.

This study is the first evidence based work evaluated the systemic use of glucosamine as an adjunctive therapy to closed mechanical debridement in chronic periodontitis. The use of glucosamine sulphate was correlated with clinical outcomes and IL1-β level in the GCF of patients with moderate to advanced chronic periodontitis
