Filter by:Smoking has been considered the most important risk factor for periodontitis among all lifestyle factors. Fewer studies evaluated longitudinal clinical and microbiological status of smokers undergoing periodontal maintenance therapy and controversial results were found. This study will evaluate clinical conditions and prevalence of putative periodontopathogens and Candida spp. in smokers and non-smokers at baseline and after 3 and 6 months of nonsurgical periodontal therapy. Clinical parameters, including oral status assessed using Plaque Index (PI), Bleeding On Probe (BOP), Pocket Probing Depth (PPD), Gingival Recession (GR), Clinical Attachment Level (CAL) will be measured in smokers and non-smokers patients with chronic periodontitis. Samples of subgingival biofilm will be obtained from the periodontal pockets and furcation sites and submitted to phenol-chloroform DNA extraction and Polymerase Chain Reaction (PCR) analysis using specific primers for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia, Campylobacter rectus, Candida albicans, Candida glabrata, Candida tropicalis and Candida dublinienses.
Periodontal diseases are a group of diseases that affect 15% of the population and in the absence of treatment causes tooth loss. Periodontal lesions are characterized mainly by strong inflammation and hyper-vascularization. Search in blood cells and inflammatory markers attempts to explain the etiological-pathogenetic mechanisms. Innate immunity can be assessed by qualitative and quantitative analysis of blood phagocytes, natural killer cells, complement, proteins of inflammation and cytokines. Current data from the literature on this subject give contradictory results and the comparison of studies are difficult because the diversity of the populations studied, evaluated cells and the methods used. The aim of the study was to evaluate the innate immunity of patients with periodontal disease and compare it with a group of patients without periodontal disease.
The PREMIERS study is a proposal for conducting an adequately powered two center phase III randomized controlled trial to test whether intensive periodontal treatment reduces the risk of recurrent vascular events among ischemic stroke and TIA survivors. The study uses the resources in both states including established dental centers, Joint Commission Certified Stroke Centers, the Schools of Public Health, and the Institute for Partnerships to Eliminate Health Disparities. The proposal addresses specific issues with regards to recruitment of African-American and rural stroke/TIA patients advocating the use of culturally appropriate strategies to educate the study subjects regarding stroke, periodontal disease and the periodontal stroke link. The study proposes to utilize economic evaluation of the periodontal intervention from the budgetary perspective. The focus will be on the financial sustainability of providing aggressive periodontal therapy (with certain, although relatively low expenditures) in exchange for a reduction of uncertain recurrent vascular events that may require high cost emergency department utilization and/or inpatient care. The sustainability of the proposed intervention after the completion of the project is integrally linked to the health economic assessment to show the health care cost savings. By integration with a rural primary care center, with an African American majority and households with average incomes below the state average, the study ensures that the proposed intervention to reduce stroke disparity is applicable to this target population.
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.
Objective The aim of this study was to test a protocol for the extraction of high quality genomic DNA from saliva samples obtained with mouthwash and taken from patients with periodontal disease. Materials and methods Saliva samples were taken from 60 patients, then stored at room temperature. DNA extraction was carried out at distinct post-sampling times (10, 20 and 30 days). Evaluation of genomic DNA was performed with spectrophotometry, electrophoresis, and PCR genotyping and sequencing.
The aim of the study is to assess the effects of low-level laser therapy (LLLT) in patients with periodontitis during orthodontic-periodontal treatment for 12 months on the following aspects: (1) Effects on periodontal status; (2) Effects on alveolar bone remodeling; (3) Effects on cervical dentin sensitivity; (4) Effects on pain and quality of life. To eliminate any bias, the investigators will initially hypothesize that there is no difference in periodontal status, jawbone remodeling, tooth sensitivity, pain and quality of life in patients having teeth with chronic periodontitis and receiving LLLT with orthodontic treatment versus teeth undergoing orthodontic treatment without incorporation of LLLT.
Several studies revealed a direct relationship between the severity of periodontal inflammation and CRP (NHANES III, Dumitriu HT et al, 1998). In patients without any other source of inflammation but PDD, proper dental treatment of the disease decreased CRP to normal levels (Dumitriu H.T. et al., 1998; D'Aiuto F. et al, 2004; Borawski J. et al., 2007) Moreover, a direct link between high levels of CRP and atherosclerotic complications has been found in studies conducted both in general population (Ridker PM, et al., 1998; Koenig W, et al., 1999) and in HD subjects (Westhuyzen J, et al., 2000; Iseki K., et al., 1999; Zimmermann J, et al. 1998).
Background: - Gum disease is a condition in which the tissue around the tooth root becomes swollen and infected. This condition can cause tooth loss if it is not treated. Who gets gum disease and how bad it will be depends on (1) the different bacteria in the mouth and (2) how the immune system of an individual handles these bacteria. Researchers want to look at the oral bacteria and genetic immune problems of different people to learn how these affect gum disease and other conditions of the mouth. Objectives: - To study how immune system problems may lead to problems in the mouth, including gum disease. Eligibility: - Children and adults at least 7 years of age who have genetic problems with their immune system. - Healthy adults that have periodontal disease - Health adults that do not have periodontal disease Design: - This study will involve a screening visit and a study visit. - Participants will be screened with a medical history, blood work and a full oral and dental exam, including dental x-rays and photos. - The study visit will involve collection of blood, urine, and other samples, including saliva, plaque, and gum swabs. Any abnormal tissue will sampled for a biopsy. Additional oral and dental exams will be performed. Participants will also answer questions about any current medical or dental problems.
The purpose of this study is to investigate the effect that obesity may have on the nonsurgical treatment (with and without the adjunct use of metronidazole) of destructive periodontal diseases (chronic periodontitis).
Periodontal disease is associated with the components of Metabolic syndrome, such as obesity, diabetes, hypertension and hyperlipidemia. Therefore, strong relation with periodontal disease and metabolic syndrome is suggested. the overall goal of this study is to define the relation between periodontal disease and metabolic syndrome, including atherosclerosis.
