Active clinical trials for "Periodontitis"

A maximum of 220 subjects with a minimum of 25 years will be recruited and examined for this 1-7 visit, up to 35 days research study: Subjects will be genotyped to identify variants of the interleukin-29 (IL29) and interleukin-28B (IL28B) genes and placed in one of the 4 groups: 50 subjects with dominant allelic variants with healthy periodontium, 50 subjects with dominant allelic variants with periodontitis, 50 subjects with IL29 (rs30461) or any of IL28B (rs11083519; rs8105790; rs8099917) single nucleotide polymorphism's (SNP) variants and healthy periodontium, and 50 subjects with IL29 (rs30461) or any of IL28B (rs11083519; rs8105790; rs8099917) SNP variants and periodontitis. Visits will consist of outpatient procedures including oral examinations, oral prophylaxis or periodontal scaling and root planing, collection of gingival crevicular fluid, dental plaque, saliva, and blood samples. Analysis will include salivary DNA isolation and pyrosequencing to determine IL29 and IL28B genotype, mediator analysis of gingival crevicular fluid, dendritic cell differentiation and inflammatory mediator analysis, and whole-genome shotgun sequencing plaque analysis. Clinical outcomes will include measurements of periodontal disease progression and inflammation, such as clinical attachment level (CAL), pocket depth (PD), bleeding on probing (BOP), gingival index (GI), and plaque index (PI). Primary Objective: To determine the impact of IL29 and IL28B SNP variants on periodontal disease expression and local inflammatory response during stent-induced biofilm overgrowth. Secondary Objective: To evaluate in vitro the impact of IL29 and IL28B SNP variants on cell-mediated, innate inflammatory response.

Although RA pathomechanisms remains incompletely understood, periodontitis and RA share pathogenic features : genetic and environmental influences, chronic inflammatory disease, immunoregulatory imbalance, bacterial factors, persistence of antigen/peptide and clinical factors (conjunctive and hard tissues destruction). Several hypothesis can be evocated : Gram negative bacterial systemic spreading, inflammatory transmitter substance systemic spreading (IL1, IL6, IL17, PGE2), systemic spreading of bacterial degradation products (LPS for example). Currently Porphyromonas gingivalis (PG) might be a susceptibility factor to RA because PG has an enzyme, the peptidylarginine deiminase leading to auto antibodies creation and RA increasing. As periodontitis, RA is chronic disease with a cyclic increase evolution, needing a complex pluridisciplinary treatment approach. Recent studies have reported an increased prevalence of RA patients with periodontal disease. Others studies show that periodontal treatment induces a significant decrease of the sedimentation rate and of the DAS28. Periodontitis is suspected to be an independent, aggravating factor in patients with RA (given the definition from NIH : an aggravating factor is something that makes a condition worse). So periodontal treatment cannot be considered as a RA treatment per se. But it is hypothesised that treating periodontitis in RA patients showing signs of periodontitis could result in improvement in RA disease activity. To date the role of periodontitis as an aggravating factor in these patients remains unclear, and only RCT designs can reasonably be used to test this causal hypothesis. There still remains some RA patients who have persistent symptoms and frequent exacerbations despite specialist care and continuous treatment, so results of treating aggravating factors are needed. As the majority of patients will benefit from a systematic evaluation and treatment of aggravating factors, the periodontal treatment strategy need to be tested. The aim of this randomised controlled trial is to assess the effectiveness of periodontal treatment for rheumatoid arthritis patients. To assess the effectiveness of periodontal treatment to reduce the severity of rheumatoid arthritis (RA), in patients suffering from both periodontitis and rheumatoid arthritis. The hypothesis is that periodontal treatment reduce the severity of rheumatoid arthritis.

The aim of this study was to formulate a mucoadhesive gel of grapes seed extract (GSE) followed by short-term clinical study for the effectiveness of this gel onto the pocket depth (PD), plaque index (PI), gingival index (GI), and bleeding on probing (BOP) when applied in periodontal pockets as an adjunct treatment for chronic periodontitis.

The purpose of this study is to determine whether full-mouth disinfection is effective in the initial periodontal treatment of generalized aggressive periodontitis on clinical parameters, gingival crevicular fluid interleukin-1β (IL-1β) and interleukin-17 (IL-17) and periodontal pathogen levels compared with conventional initial periodontal treatment and full-mouth initial periodontal treatment. The investigators' hypothesis is to test whether full-mouth disinfection in the initial periodontal treatment of generalized aggressive periodontitis enhance the clinical, biochemical and microbiological parameters in comparison to conventional initial periodontal treatment and full-mouth initial periodontal treatment.

combining the non-surgical therapy with a well-tolerated substance that can stimulate protective immune responses like B-glucan, might effectively mount resolution pathways contributing to resolving of the chronic lesion observed in aggressive forms of periodontal disease.

The purpose of this study is to determine whether scaling and root planing as a periodontal intervention helps in improving the overall health of patients suffering from coronary heart disease.

The aim of this study was to compare the success after endodontic treatment performed with or without continuous ultrasonic irrigation. 70 Mandibular molars with diagnosis of pulpal necrosis and with periapical radiolucency were randomly assigned into two treatment groups- continuous ultrasonic irrigation (CUI) and syringe irrigation (SI). Standard nonsurgical endodontic treatment was performed on both groups under rubber dam isolation with 0.02 taper ISO stainless steel hand files using step back technique. In both groups, 5 ml of 5.25% sodium hypochlorite was used as irrigant after each instrument. After root canal instrumentation, canals were irrigated with 5 ml of 17% EDTA solution for 1 minute. In SI group, canals were flushed with 15ml of 5.25% sodium hypochlorite using a 27 gauge needle while final irrigant was delivered using a continuous ultrasonic irrigation device in CUI group. An inter-appointment dressing of calcium hydroxide was given and patient was recalled after one week and canals were obturated with the Gutta Percha. Immediate postoperative radiograph was then taken, followed by radiographs at 3, 6, 9 and 12 months.

The oral cavity is mostly influenced by general health. The oral microbiota which is as complex as the gastro-intestinal or vaginal microbiota are considered to be difficult therapeutic targets. The effects of probiotics in different fields of health care have resulted recently in the introduction of probiotics for oral healthcare. Probiotics have been clinically proved effective in different fields of oral healthcare such as halitosis, oral candidiasis and tooth decay. They have also been inducted in the field of periodontal healthcare because of the current views on the etiology of plaque- related periodontal inflammation.

BACKGROUND: Chronic periodontitis (CP) is an inflammatory condition affecting tooth supporting tissues and alveolar bone that surround the tooth leading to formation of deepend gingival sulcus that is highly prone to pathologic changes, ultimately bone resorption and tooth loss. In the literature, several pharmacologic agents have been administration via local delivery route, directly into diseased sites affirming greater improvement in periodontal status. Therefore, present study was conducted to determine the clinical effectiveness of subgingivally delivered 1.2% Rosuvastatin gel incorporated into an methylcellulose vehicle for its controlled release into intrabony defect sites in adjunct to scaling and root planing for treatment of chronic periodontitis patients. MATERIAL AND METHODS: Sixty five patients were categorized into two treatment groups: group I -SRP plus RSV, 1.2 mg and group II -SRP plus placebo. Clinical parameters included modified sulcus bleeding index (mSBI), probing depth (PD), and clinical attachment level (CAL), were recorded at baseline before SRP and at 1, 3, 4, and 6 months. Radiologic assessment of intrabony defect (IBD) fill was analysed at baseline and after 6months using computer-aided software.

The objective of this study was to evaluate whether short-term full mouth disinfection protocol could have a greater reduction in the levels of halitosis and volatile sulfur compound or not, when compared to quadrant-wise scaling and root planing
