Filter by:This current study aims to clarify the relationship between the occurrence of Entamoeba gingivalis infection and the specter of gingivitis & chronic periodontitis among Egyptian patients in comparison to healthy volunteers as a control group.
Periodontal diseases and caries are essentially initiated and progressed by accumulation of dental plaque. Thus, daily effective plaque control is valuable as a preventive measure and maintaining oral health. Mechanical plaque control is important but has limitations; therefore, an adjunctive chemical plaque control such as mouthwash is helpful. Various medicinal plant-derived galenicals might be used as safe and stable alternatives to synthetic mouthwashes. For example, a combination of Salvadora persica L. (Sp) root sticks and green tea (Gt) aqueous extract has been found to reduce plaque accumulation over 24 hours. Moreover, these extracts were reported to have anti-microbial activity against many oral bacteria. The objective of this study was to investigate the efficacy of the combination of Gt aqueous extract and Sp aqueous extract in reducing plaque buildup for 4 days duration.
Periodontal disease refers to inflammatory disease of the periodontium caused by the host and/or pathogenic microorganisms. Anti-inflammatory and pro-inflammatory cytokines play a role in the periodontal inflammation process. The aim of this study was to evaluate the levels of hepcidin, interleukin (IL)-6, and IL-10 levels in gingival crevicular fluid (GCF) and in serum samples obtained from individuals with periodontal inflammation.
Objectives: Alveolar resorption is one of the most important events in periodontitis. Osteoclast activity is regulated by the ratio between receptor activator of NF-κB ligand (RANKL) and osteoprotegerin (OPG). The aim of this study was to evaluate changes in the RANKL/OPG ratio in crevicular fluid after periodontal treatment. Material and methods: A total of 15 patients with periodontitis were included in the study group. Samples were collected from an area with active periodontitis and a healthy area. The RANKL and OPG levels were measured before and after periodontal scaling and root planing (SRP) treatment. The study group was compared to the control group, which included 10 patients without periodontitis.
Sialic acid (SA) is the generic term given to a family of acetylated derivatives of neuraminic acid. SA is a 9 carbon monosaccharide. An important function of host SA is to regulate innate immunity. SA is present in several acute phase proteins which are known to be associated with periodontitis. There exists a need for a biomarker, for early detection of disease evolution and more robust therapy efficacy measurements. Till date, there is very little data regarding simultaneous estimation and comparison of total SA content in saliva. IL-10, an anti-inflammatory cytokine, regulates the synthesis of pro-inflammatory cytokines such as IL-1, -2, -6 and stimulates protective antibody production. IL-10 is expressed in both healthy and diseased human periodontal tissues and is reported to be reduced in patients infected with Aggregatibacter actinomycetemcomitans. The present study was therefore undertaken with an aim, to not only assess the levels of TSA(Total sialic acid levels),but also of IL 10 levels in saliva from stage 1(mild) to stage 2(moderate) periodontitis patients
The aim of the study is to evaluate the effects of low-level laser therapy (LLLT) on patients with chronic periodontitis during a post-orthodontic period for 12 months. Following aspects will be assessed: 1. Effects on tooth stability maintenance and bone remodeling. 2. Effects on periodontal inflammation status. 3. Effects on cervical dentin sensitivity and quality of life. The study design is a randomised controlled trail. To eliminate any bias, the investigator will initially hypothesis there is no significant difference in the aforementioned aspects between teeth retained with an adjunctive LLLT strategy and those retained in a conventional regimen.
Unfavorable systemic conditions condition a low resistance of the host to the virulence of the aggressive agent, causing in a periodontal disease and may lead to difficulties in the therapeutic response. The longer the duration of diabetes, it is suggested that greater severity of periodontal disease and loss of insertion. The objective of the present study will be to evaluate the clinical, microbial and immunological characteristics in diabetic subjects with chronic periodontitis submitted to non-surgical periodontal treatment. Will be 120 individuals with chronic periodontitis, including 60 type 2 diabetic subjects and 60 healthy should receive and have access to the informed consent form. Medical and dental clinical examination should be performed and evaluation microbial and immunological properties of gingival fluid and saliva respectively. Non-surgical periodontal therapy with subgingival scaling should be performed in all individuals who will be evaluated at two times: at the beginning and after 90 days of the periodontal therapy with new performing clinical exams and collecting oral samples, oral hygiene instructions will be addressed in two sessions. The data will be subjected to appropriate statistical tests and shall provide a comparison between the times. There seems to be a relationship between type 2 diabetes and periodontal disease and studies that provide the implementation of therapy are essential for clarifying the relationship.
The premise of the relationship between the atherosclerotic process of coronary artery disease and periodontal disease is the immunoinflammatory process, which causes a significant increase in serum concentration of mannose-binding lectin. This protein is part of the innate immunity and has the ability to bind to the mannose residues common to various pathogens. Animal studies also showed that increased serum concentration of sirtuin-1 was associated with reduced inflammation. Evidence indicates that sirtuin-1 plays an important role in vascular protection and is associated with aging. OBJECTIVES: This study examined the influence of non-surgical treatment of periodontal disease on the serum concentration of mannose-binding lectin and sirtuin-1 in patients with periodontal disease and coronary artery disease. METHODS: Seventy-eight patients, 38 women and 40 men, mean age 58 ± 8 years old, were divided into 4 groups: 20 healthy subjects (group 1), 18 patients with coronary artery disease and without periodontal disease (group 2), 20 patients with periodontal disease and without coronary artery disease (group 3) and 20 patients with coronary artery disease and periodontal disease (group 4). Peripheral blood samples were collected at the beginning and at the end of the treatment of periodontal disease.
The goal of this project is to analyze the effectiveness of calculus and biofilm removal using area-specific hand scalers such as Mini Five® Gracey Curettes and Micro Mini Five® Gracey Curettes in periodontal pockets that are 5mm or greater. The data collected from this project will provide the evidence needed to support the use of modified hand scalers during non-surgical periodontal therapy for clinicians.
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)
