Active clinical trials for "Chronic Periodontitis"

Periodontitis are inflammatory diseases characterized by the destruction of the tooth-supporting bone due to increased bone resorption by osteoclasts (OCLs). Two forms are described: chronic periodontitis (CP) and aggressive periodontitis (AP) that differ by the severity and rapidity of bone loss, much more important for AP than CP. In both forms, the link with uncontrolled activation of the immune system is largely admitted. Despite the physiopathology of CP is fairly well studied, very few data are available regarding AP. The investigators aim is to understand the severity of AP by analyzing the proportion and action of immune and mesnchymal cells potentially involved in bone destruction, on biopsies of periodontal granulation tissue (surgical waste) and blood. Three groups of 20 patients will be included: affected with AP, CP or controls (necessitating an extraction of wisdom teeth).

A randomized controlled triple blinded study to evaluate the effectiveness of Salvadora Persic (SP) as an adjunct to Scaling and Root Planing (SRP) in chronic periodontitis by comparing the basic parameters of periodontitis, radiographs and bacterial levels with a controlled group (SRP only).

The subjects participating in the trial will be randomly allocated to either the group receiving the treatment under investigation (scaling and root planning (SRP) accompanied by administration of vitamin D) or to a group receiving standard treatment (SRP in conjunction with placebo) as the control. Random assignment of intervention will be done after subjects have been assessed for eligibility and recruited, but before the intervention to be studied begins. After randomization, the two groups of subjects will be followed in exactly the same way and the only differences between them will be the vitamin D/placebo that they will receive.

This study is to evaluate the safety and efficacy of Gingiva Mesenchymal Stem Cell Therapy for Chronic Adult Periodontitis.

Studies reveal association between dry conditions and decreased healing in wounds or any treatment. From these studies, it can be hypothesized that healing in mouth breathers after scaling and root planing in terms of bleeding on probing, gingival index, plaque Index, clinical attachment level, probing depth may not show as much improvement as in case of nose breathers. No study has been conducted till date to find effect of scaling and root planing in periodontitis patients among mouth breathers and nose breathers.

The purpose of this study is to evaluate the safety of clinical injection of allogeneic human dental pulp stem cell(DPSC) in local infected periodontal tissue and determine whether injection of allogeneic DPSC is a effective way in the treatment of chronic periodontal disease.

This study was conducted to evaluate by clinical and microbiological parameters the effect of locally delivered propolis as an adjunct to scaling and root planing in the treatment of chronic periodontitis.

This study evaluates the diagnostic performances of Point of Care P. gingivalis test in saliva with serum IgG P. gingivalis, in reference to dental examination as a gold standard in patients hospitalised in intensive care unit (ICU)

Aim of the study is the efficiency assessment of porous Metronidazole loaded matrix based on gelatin/hydroxyethylcellulose blend in treatment of deep periodontal pockets resulting from severe chronic periodontitis. The matrix was invented and produced in Department of Drug Form Technology, Wroclaw Medical University. The porous metronidazole (MTZ) loaded matrix was fabricated by the freeze-drying technique. The morphology, mechanical properties, in vitro degradation, MTZ release from dried sponge were evaluated and also the clinical trials were performed. Patients suffering from chronic periodontitis are examined. To evaluate oral hygiene API (Approximal Plaque Index) and the gum inflammation BOP (Bleeding on Probing) and PBI (Papilla Bleeding Index) indices are used. The clinical examination is performed 3 times. On the first visit the output indicators are defined. The subgingival scaling is performed and Metronidazol on porous matrix is applied to the selected periodontal pockets. 2 control tests of periodontal indices are carried out after one week and one month from the application. In the control group after scaling/root planing procedure, there is no application of metronidazole.

Cell sheet technique possess the properties of conserving the ECM, rich molecules and retaining cell vitality, and will promote the capacity of cell adhesion and proliferation. The stem cell based cell sheet therapy has been utilized in many fields and scored the satisfactory results. Periodontitis is a chronic disease which causes the destruction of the periodontal tissue and leads to the teeth loss in the end. The routine cell-based therapy to the periodontitis was confronted with many difficulties. In the investigators previous preclinical research, +the investigators fabricated periodontal ligament stem cell (PDLSC) pellets and cell sheet fragment and applied them in the periodontal defect area for tissue regeneration and periodontitis treatment. And the investigators carried out a comprehensive study of the PDLSC allograft. The host responses and implanted cell fates were recorded. After the scientific investigation of the preclinical study, the investigators designed the preliminary clinical trial of PDLSC cell sheet for the chronic periodontitis therapy in the aims to test the PDLSC fates and explore one ideal transplantation mode.
