Active clinical trials for "Chronic Periodontitis"

The expression and quantification of Micro-RNA 146-a, was analyzed in the subgingival plaque samples of generalized chronic periodontitis patients with and without coronary heart disease. The demographic variables and periodontal parameters were assessed and correlated with expression of micro-RNA 146-a. The quantification of levels of micro-RNA 146-a was done using Real time Polymerase chain reaction. ( RT-PCR)

In the present clinical study including chronic, aggressive periodontitis and healthy individuals, the investigators aimed to determine the RANKL, osteoprotegrin (OPG), Interleukin-1 (IL-1β), IL-10, IL-1β levels in gingival crevicular fluid(GCF) before and after surgical periodontal treatment and search out the relationship of clinical parameters with these cytokine levels.

Periodontitis is a chronic inflammatory disease whose etio-pathogencity is not fully understood yet. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are involved in physiological and pathological processes. Nitro-oxidative stress has been implicated in Periodontitis. The aim of this study is to assess the levels of ROS and RNS in serum and gingival crevicular fluid (GCF) samples taken from periodontitis (chronic and aggressive) patients and healthy controls. Subsequently, correlating these levels with the severity of periodontal disease. Eighty subjects will be invited to participate in this study. Patients will be allocated into four groups (20 patients each). The biochemical parameters that will be investigated are Malondialdehyde (MDA) (using TBRSA assay) as a marker of oxidative stress and (NO- level using Griess reagent) as a marker of nitrosative stress.

The aim of this study was to investigate the impact of glycemic control on clinical periodontal status, levels of malondialdehyde (MDA), glutathione peroxidase (GSH-Px), reduced glutathione (GSH) and paraoxonase (PON) activity in gingival crevicular fluid (GCF) and blood samples of type 2 diabetes mellitus (T2DM) patients with chronic periodontitis (CP).

This study comparatively evaluate the expressions of MMP-2 and MMP-9 in smoker vs non-smoker chronic periodontitis patients as well as periodontally healthy subjects. the hypothesis of this study was that smoking may interfere with periodontal disease by effecting MMP-2 and MMP-9 expressions.

Present study intended to compare diseased and healthy sites in chronic and aggressive periodontitis with healthy individuals. The investigators suggest that even unaffected healthy sites of both chronic and aggressive periodontitis patients exhibit subclinical inflammation and tissue destruction with decreased fibroblast cell counts and increased inflammatory cell counts. Investigators also suggest that a possible mechanism which might play a role in the disease progression might occur via a disbalance between matrix metalloproteinases and their inhibitors, and increased hypoxia in diseased sites.

Periodontitis is a widely prevalent disease worldwide that has serious public health consequences. Its prognosis includes tooth loss and edentulism, a condition that negatively affects chewing causing functional disability; and esthetics causing social impairment. Consequently, periodontitis may end up causing marked impairment of the quality of life of the affected patients, impairment of general health and increasing the dental care costs significantly. Dysbiotic changes in the oral microbiome arise after some microbial species are enriched by primary products resulting from tissue breakdown due to gingivitis. It then triggers the host cells to produce proteinases that mediate loss of marginal periodontal ligaments, apical migration of the junctional epithelium and apical spread of bacterial biofilm. However, the dysbiotic changes may be more likely to occur in some patients rather than others due to certain risk factors including smoking and immuneinflammatory responses. Thus, the severity of periodontal disease in these patients would be higher. Tobacco smoking is no longer considered to be a habit, but a dependence to nicotine and a chronic relapsing medical disorder. Among its detrimental effects on general health, tobacco smoking increases the risk of periodontitis by 2 to 5 folds. This takes place by increasing the dysbiotic changes in the oral microbiome and so, increasing the severity and extent of the periodontal disease at a younger age. Therefore, smoking has been considered as a modifying factor of periodontitis that should be considered upon periodontitis case grading definition. Therefore, this research aims to identify the difference in dysbiosis between the three categories of periodontitis, trying to understand the cause of the resistance of each category to treatment compared to the milder category.

Subjects were selected from the outpatient clinic, Department of Oral Medicine and Periodontology, Faculty of Oral and Dental Medicine, Cairo University. Ten healthy control subjects presented with clinically healthy periodontium. Ten patients who had plaque induced gingivitis. Ten patients who had generalized chronic periodontitis. Ten patients who had generalised aggressive periodontitis. Pentraxin-3 levels were evaluated in GCF and saliva of all subjects included in this study with ELISA technique.

This study will evaluate if periodontal mechanical treatment is capable to alter immunological and genetical parameters related to systemic health in patients with chronic periodontitis ant diabetes type 2.

The purpose of this study is to determine whether Lactobacillus reuteri-containing lozenges (Prodentis) are effective in treatment of halitosis in patients with chronic periodontitis.
