Filter by:Periodontitis is the inflammation of the tissues supporting the teeth. Lemongrass (Cymbopogon Citratus) oil mouthwash can be used with subgingival scaling in the treatment of periodontal diseases. Transforming growth factor beta (TGF-β) is a multifunctional cytokine belonging to transforming growth factor superfamily and its elevated levels are detectable in inflammatory and healing process The present project will be conducted to evaluate the expression of TGF-β levels in chronic periodontitis patients after ultrasonic scaling and using 0.25% lemongrass oil mouthwash. TGF-β is a salivary marker of periodontitis.
Aim: A prospective randomized, controlled clinical trial comparing two groups of a cohort of Rheumatoid Arthritis (RA) patients with periodontal disease will be carried out to identify if the effect of non-surgical periodontal therapy is a predictor of remission/ low disease activity (LDA)-remission. Methods: 42 patients with RA and periodontitis from the RA Almenara cohort will be included (ACR 1987 and or ACR/EULAR 2010 criteria with more than 16 years old at diagnosis); those with <6 teeth, current infections, cancer or oral precancerous lesions, diabetics, Sjogren's syndrome, use of antibiotics or drugs associated with dry mouth and dental surgery, will be excluded. Periodontal Disease was defined by the presence of periodontitis stage 3 or 4 with at least 2 non-adjacent teeth with insertion loss >=5mm, probing depth >=5mm and bleeding on probing according with the 2018 periodontitis diagnostic criteria. Two RA patients groups will be follow up by monthly visits. Patients will be divided into two groups (intervention and no intervention treatment). PD treatment will be performed by a qualified periodontist. No intervention group will receive PD treatment after 6 month visit because ethical principles. Disease activity will be determined according with DAS 28index, Clinical Disease Activity Index (CDAI) and Simple Disease Activity Index (SDAI) scores, C-reactive protein (CRP), the erythrocyte sedimentation rate (ESR), and rheumatoid factor levels will be registered before and after PD treatment (baseline, 3 and 6 months visits), and the differences between the groups will be analyzed and compared. Periodontal parameters including probing depth (PD), clinical attachment loss, and sulcus bleeding index (SBI) will be correlated with the factor levels.
The suppression of chronic periodontitis after application of dental gel and toothpaste containing cannabidiol (CBD) will be evaluated.
Smoking negatively affects the prognosis of periodontal disease by impairing tissue healing. While micronucleus is the most popular parameter for demonstrating DNA damage, inflammatory cell and vascular densities are the most evaluated parameters for determining histopathologic changes in the periodontium. This cross-sectional study aimed to evaluate the effects of heavy cigarette smoking and generalized periodontitis on local genotoxic damage to exfoliated oral epithelial cells as well as histopathologic damage to the periodontium. The investigators hypothesized that the genotoxic and histopathologic damage would be increased in smokers with generalized periodontitis.
Life expectancy has dramatically increased in the last century, although this process has not been always accompanied by an equivalent increase in healthy life expectancy. However, extending longevity without decreasing the risk of age-associated pathologies would not be desirable since non-communicable diseases can diminish seniors' quality of life, raise health-care costs, and increase pressure on family members who are responsible for their care. Maintaining a good health would help to ensure independence, security, and continued productivity in the later years helping both health systems and pensions lower costs. Thus, many scientific studies have tried to delay the age of onset of major age-related chronic diseases. In other words, research has been more focused on extending healthspan rather than lifespan. Actually, numerous experimental studies have shown that the extension of lifespan by modifying risk factors is usually accompanied by delayed or reduced morbidity, including cardiovascular disease, neurodegeneration, and tumors. In the dietary context, modifications of the diet energy and/or macronutrient balance has shown to contribute to healthy aging, increasing healthspan and probably lifespan. Likewise, some foods would be able to supply a significant amount of compounds to the human diet, including non-nutrients which are thought to exert effects in the same sense. Thus, adequate nutritional intervention would be considered geroprotective interventions that would positively influence health by slowing basic biological processes of aging, such as cellular senescence, mitochondrial dysfunction, age-related decline of stress resistance, dysregulated cellular energy sensing/growth pathways, impaired proteostasis, deteriorated stem cell function/bioavailability, as well as inflammation/oxidative stress. The use of nutraceuticals and functional foods from olive products and by-products can be useful in the treatment of pathologies associated with aging, such as periodontitis, as well as from the point of view of a proper nutrition during aging. The study is a double-blind clinical trial of parallel design whose main objective is to evaluate the usefulness of a dietary supplement rich in oleuropein from the olive tree (leaf) in the adjuvant treatment of patients with age-related periodontitis. Efforts will be made to ensure that men and women be represented homogeneously in all study groups, although it is known that gender does not influence the appearance of periodontitis. The experimental design foresees the inclusion of 130 patients with chronic periodontitis aged 60 years or older, 65 for the control group and 65 for the treatment group. Volunteers will be recruited from new patients attending the Faculty of Odontology at the University of Sevilla, Sevilla (Spain) by one study team member. The investigational product will be provided by Natac Company (Madrid, Spain), a corporate group dedicated to researching, developing, manufacturing, and marketing natural ingredients to be used in food supplements, feed, pet food, as well as in functional foods, and as natural, active pharmaceutical ingredients. The planned schedule for the participating subjects is as follows: - Day 0: diagnosis of periodontitis, proposal to participate in the study, delivery of consent and information to the patient. - Day 15: oral exams, collection of sociodemographic data, study of anthropometric characteristics and blood pressure, evaluation of eating habits, urine and blood sampling, collection of samples for the study of the periodontal microbiota and data collection and calculation of the index of successful ageing. - Day 16 to 30 periodontal treatment. - Day 16 to 136: administration of treatment (oleuropein or placebo). - Day 136: oral exams, collection of sociodemographic data, study of anthropometric characteristics and blood pressure, evaluation of eating habits, urine and blood sampling, collection of samples for the study of the periodontal microbiota and data collection and calculation of the index of successful ageing. The analytical part of the of the clinical trial will be developed mostly in the Biomedical Research Center (CIBM) of the University of Granada. The field part of the clinical trial in patients with periodontitis will be carried out at the Faculty of Dentistry of the University of Seville. The design of the clinical trial provides for the participation of specialists from several disciplines, including specialists in Nutrition and Physiology, clinical specialists in Pathological Anatomy and Dentistry, technicians from the Center of Scientific Instrumentation of the University of Granada (specialists in various subjects such as microscopy, biochemical analysis, histology and veterinary) as well as technicians from the Marketing Unit of the OTRI of the University of Granada.
Patients diagnosed with stage III or IV periodontitis during routine visits at the department of periodontology will undergo a validated questionnaire to understand the impact of the disease on their quality of life.
Irisin is novel adipomyokine known as a mediator of physical activity that produced mainly by skeletal muscle and adipose tissues. It is cleaved from the fibronectin type III domain-containing protein 5 (FDNC5), which is, in turn, induced by peroxisome proliferator-activated receptor-ɣ co-activator 1-α (PGC-1α). Several studies reported that irisin is related with pathogenesis of many diseases which are known to be associated with periodontal disease such as obesity, diabetes mellitus, rheumatoid arthritis, cardiovascular disease, nonalcoholic fatty liver disease and metabolic bone diseases. There are several studies those have reported that increased IL-6 levels are associated with progression and severity of periodontitis . Recently, it has been shown that irisin is expressed in human periodontal ligament cells (hPDL), dental pulp stem cells and osteoblasts. Also, a few studies revealed that irisin promotes growth, migration and matrix formation in hPDL cells and cementoblast differentiation. To the best our knowledge, there 's one study has been reported that the higher levels of irisin in saliva in patient with chronic periodontitis
RESEARCH QUESTION: Will there be a difference in periodontal health of two groups of periodontally compromised orthodontic patients with early and delayed start of orthodontic treatment after periodontal surgery? Population: Adult orthodontic patients with periodontally compromised dentition requiring periodontal surgical management Intervention: Fixed orthodontic treatment started 10 days after periodontal surgery Control group: Fixed orthodontic treatment started 3 months after periodontal surgery Outcomes: changes in osseous (Alveolar bone level) and non-osseous (PI, GI, BOP, PD, CAL) periodontal parameters of the teeth involved in periodontal surgery. Time frame: One year and four months Study Design: Prospective, randomized controlled clinical trial. Specific: Yes Measurable: Yes Achievable: Yes Relevant: Yes Time: One year and four months Feasible: Trained staff, infrastructure, time, study design Interesting: A new treatment protocol will be investigated. Novel: No study comparing these waiting time intervals after periodontal surgery before starting orthodontic treatment. Ethical: Yes Relevant: As there is no clarity on waiting period after periodontally surgery in periodontally compromised adult patients, this study will be of great help in establishing treatment management protocol of such patients.
There are no studies comparing reinstrumentation and flap surgery for the treatment of residual periodontal pockets. The aim of this RCT is to compare the re-instrumentation vs the flap surgery in terms of PD reduction, CAL gain, gingival recession, need of an additional surgery and pocket closure. Moreover, PROMs will be evaluated
This study is to evaluate whether non-surgical periodontal therapy can help to control the cardiovascular risk among patients with moderate/severe periodontitis and at risk of cardiovascular disease.
