Active clinical trials for "Periodontal Diseases"

Periodontal disease is a multifactorial inflammatory disease of infectious origin. The last epidemiological study concerning periodontitis in France was carried out in 2002-2003 by Bourgeois et al and shows that 95.4% of the patients have a loss of attachment and 82.23% have associated periodontal pockets. The presence of bacteria, mostly Gram-negative anaerobes, is not sufficient to explain the heterogeneity of clinical forms. Indeed, there are different risk factors influencing the frequency and severity of periodontitis. Moreover, the link between systemic pathologies and periodontitis has been widely established: it concerns metabolic syndromes, cardiovascular pathologies, premature pregnancies, autoimmune diseases and Alzheimer disease. Some research has been done on biomarkers found in periodontitis. Among them, the investigators quote the study which took place within the laboratory of Biochemistry - Clinical Proteomics of Pr Lehmann Sylvain by Mertens et al. It is the only study to date that has established an LC-MRM proteomic profile characteristic of periodontitis: indeed, 4 proteins of plasma origin were highlighted thanks to this technology: hemopexin (HEMO), plasminogen (PLMN), apolipoprotein H and α-fibrinogen (FIBA) were correlated with the presence of periodontitis compared to the control group (p<0.05).

The goal of this study is to evaluate the capacity of allogeneic bone marrow mesenchymal stromal cells (MSC) to induce bone regeneration in patients with periodontal disease. MSC cultured are loaded on a collagen scaffold, included into autologous platelet rich plasma clot and implanted in the bone defect.

Previous studied have investigated the pathophysiological role and expression of Cathepsin K (Ctsk) , receptor activator of the NF-κB ligand (RANKL) and periostin in active periodontitis and peri-implantitis lesions. However, the potential influence of non-surgical periodontal therapy including scaling and root planning on the bone remodeling markers level over different trial times have not well determined. Thus, the current research is conducted to address this influence. Thus, the research question will be: In patients with periodontitis, does the level of bone remodeling markers altered after successful NSPT during different healing time periods?

Ageing of the world's population is accelerating. Despite the health challenges they face, older people should not be stereotyped as frail and dependent. Healthy ageing is possible if adequate care is provided and effective intervention is delivered for healthy living. Common oral diseases (dental caries and periodontal diseases) are determined to a great extent by health behaviours (diet and oral hygiene) and are controllable through effective interventions. Hence, this study aims to test the theoretical models for health promotion, develop theory-derived intervention, and evaluate its effectiveness in improving oral health of older adults. The study hypothesis is that theory-derived intervention is more effective than conventional health education in eliciting positive behaviours and controlling oral diseases in older adults.

Hypothesis: There will be an additional reduction of pocket depth and gain of clinical attachment when dehydrated human amnion-chorion membrane (dHACM) is placed into the periodontal disease defect after mechanical scaling and root planing. Specific Aim 1: to compare the clinical and radiographical outcome of using dehydrated human amnion-chorion membrane (dHACM) (commercially available as BioXclude®) with mechanical scaling and root planing.

The present study aimed to assess the effect of non-surgical periodontal treatment on serum and salivary IL-1beta, IL-18, NLRP3, ASC and Caspase-1 levels in gingivitis and Stage III Grade C periodontitis. 15 periodontally healthy, 15 gingivitis and 15 Stage III Grade C periodontitis patients were enrolled. At baseline, serum and saliva samples were collected and the whole mouth clinical periodontal parameters were recorded. Periodontitis and gingivitis patients received non-surgical periodontal treatment. Clinical parameters were re-measured and samples were re-collected at 1 and 3 months after treatment. Serum and salivary protein levels were analyzed by ELISA. Data were analyzed using appropriate statistical tests.

Periodontitis is an inflammation associated with destruction of the periodontium that ultimately, if not treated, leads to tooth loss. Clinically, it is characterized by clinical attachment loss (CAL) and bleeding on probing (BOP) accompanied by increased probing pocket depth (PPD) and/or gingival recession. The standard periodontitis treatment aims to restore the homeostasis of the immune system by mechanically reducing the microbial load to levels that are compatible with stability and health. This is achieved by professional mechanical biofilm control and motivation of the patient for oral hygiene measures in order to control the biofilm and avoid disease recurrence. Conventional scaling and root planing (SRP), and air polishing therapy are tools used for professional biofilm control. More recently, air-polishing devices have become a promising alternative to conventional SRP in reducing the clinical time and causing less discomfort and pain for the patients. The objective of this study is to evaluate the efficacy of subgingival erythritol air polishing for initial periodontal pocket healing.

Background: Association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been widely studied and the aspiration of periodontal pathogens is one of the most accepted causal mechanisms for pulmonary exacerbation. Bronchiectasis is clinically quite similar with COPD, including chronic administration of antibiotics, increased systemic inflammation and relatively similar clinical symptoms, but for the time being; there are no studies that have correlated this condition to PD. This study will evaluate if the scaling and root planning (SRP) associated with photodynamic therapy improves periodontal clinical parameters, halitosis, and the quantity of microorganisms associated with exacerbation of bronchiectasis in saliva, subgingival periodontal microenvironment, sputum and nasal lavage at baseline, after 3 months and one year of SRP. Methods/Design: Ninety patients with chronic periodontal disease and bronchiectasis will be enrolled in the study and they will be treated as follow:G1 control (n = 30) - supragingival scaling (SS) and dental hygiene orientation (DHO); G2 experimental (n = 30) - SRP + DHO; G3- experimental (n = 30) - SRP + PDT + DHO. The quantification of bacterial groups commonly associated with exacerbation of bronchiectasis (P aeruginosa, S. aureus) and periodontal diseases (P. gingivalis), will be evaluated in periodontal pockets, saliva, nasal lavage and sputum by quantitative PCR at baseline 3 months and one year after the SRP. G1 patients will receive SRP upon completion of the investigation. If the mean depth of probing of this group worsen (> 1mm) at 3 months they will be excluded from the study, treated (SRP) and the data will be described. Discussion: The results of this protocol will determine the efficacy of periodontal treatment in decreasing the total amount microorganisms in saliva periodontal pocket, sputum and nasal lavage, the most probable niches of bronchiectasis exacerbation, and reducing local inflammation and halitosis after 3 months and one year. It is expected an higher improvement in all parameters measured over 3 months and 1 year for G3

This is a randomized, single blind, parallel-arm, multi-center, non-inferior clinical trial. 174 patients are recruited in total, and they are treated by Guided Tissue Regeneration (GTR). The patients are split in to two groups evenly: 87 in the experimental group and 87 in the control group.

The goal of this clinical investigation is evaluation the agreement between the periodontal pocket depth measurement obtained by periodontal probing (gold standard) and the measurement obtained by the ultrasound device
