Active clinical trials for "Periodontitis"

The study will be a single center, longitudinal prospective, triple blind (investigators, patients and statistician), randomized design. After informed consent, a target population of about 75 healthy adult volunteers with periodontitis will be included in the study. Patients will be randomized and categorized into three experimental groups each containing 25 patients. The randomization process will be carried out by use of sequentially numbered opaque sealed envelopes (SNOSE method).The recording of all the soft tissues data plaque index, gingival index, the modified sulcus bleeding index and the periodontal probing depth and clinical attachment level will be carried out at baseline, 4 weeks, 8 weeks, 12 weeks and will be maintained till 24 weeks for efficacy and safety evaluation.

To evaluate the security and efficacy in the administration of encapsulated acellular system derived from Mesenchymal Stem Cells as a novel regenerative endodontic procedure which to promote the pulpar regenration.

Main Purpose: To evaluate the effect of photodynamic therapy on soft tissue healing after tooth extraction at periodontal infection site, and to compare the effect on pain degree and bone tissue remodeling after tooth extraction.

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.

This early-stage research is designed to determine the efficacy of the Lumoral method in chronic periodontitis patients. Improved supragingival plaque control can help to also sustain the subgingival plaque management in the long term. In addition, the device might have a photobiomodulation effect on periodontal tissues.

This study evaluates the effect of leucocyte and platelet rich fibrin Block (L-PRF Block) during endodontic microsurgery (EMS) on patient's post-operative comfort and periapical bone healing in large peri-apical lesions.

Recently, Herbal formulations have gained wide popularity in management of Dentinal hypersensitivity owing to the additive effects of active anti-inflammatory ingredients like Curcuma longa, Clove oil, Acacia arabica and Spinach leaves in addition to desensitizing ingredients like Potassium nitrate and/or Sodium fluoride. Jasmate herbal formulations which contains Potassium Nitrate along with aqua, calcium carbonate, sodium cocoyl glutamate, sorbitol 70%, glycerin, curcuma longa, arginine hydrochloride, erythritol, sodium saccharin, hydrated silica, sodium carboxymethyl cellulose, elettaria cardamomum, foeniculum vulgare, melaleuca leucadendra, eucalyptus globules, aloe barbadensis, carnosic acid, zinc oxide, hydroxyapatite, propolis, hippophae rhamnoides, syzygium aromaticum, myrtus communis, sodium benzoate and sodium fluoride7, where such formulations claim to have an anti-inflammatory action due to the active ingredient i.e. curcuma longa which further reduces the DH and have a synergistic effect. Efficacy of desensitizing preparations containing the above ingredients, in the form of Jasmate was tested in the laboratory along with BioMin F and results were encouraging with sufficient occlusion of the dentinal tubules in both the groups without statistically significant differences in the results. The biocompatibility (cytotoxicity) of Jasmate toothpaste preparation was evaluated in the laboratory by using human gingival fibroblasts at different concentrations. Different tests like cell cycle analysis, apoptosis / necrosis and MTT were done and Jasmate toothpaste preparation showed the lowest cytotoxicity as compared to BioMin F toothpaste preparation. Jasmate toothpaste preparation showed more than 92% of live cells in all concentrations. The current randomized controlled clinical trial will be conducted to evaluate safety and efficacy of Jasmate toothpaste preparation in the management of DH post scaling and root planing in patients with chronic periodontitis.

The objective of this study was to assess the effectiveness of NIPSA in periodontal lesions with deep supra-alveolar defects, measuring the clinical efficacy of this flap. The non-incised papilla surgical approach (NIPSA) is a novel technique that accesses the periodontal defect from apical direction and was established with the aim of creating clinical advances compared with marginal access techniques. The defects with a supra-alveolar components are more frequent than intrabony defects, there is very little evidence about their treatment .

Periodontitis has been linked to increased risk of cerebrovascular disease. Impaired brain hemodynamics has been suggested as early markers of cerebral macro and microangiopathy. Therefore, the aim of this clinical trial will be to assess the potential effect of periodontal treatment on cerebral hemodynamics in otherwise healthy patients with severe periodontitis over 6 months.

Dental staining may interfere with compliance with chlorhexidine mouth rinse use Thus, developing strategies to control tooth staining associated with chlorhexidine use may be relevant for improving compliance. Thus, a new anti-staining toothpaste formulation (Dentaid, Barcelona, Spain) has been recently developed, aiming to interfere with the development of extrinsic staining associated with chlorhexidine use (preventive action), but also with the capacity of removing staining already formed. For that, the proposed formulation includes hexametaphosphate, tripolyphosphate and polyvinylpyrrolidone (PVP), within its ingredients. Thus, it may be relevant to test the efficacy of this new anti-staining toothpaste formulation in two consecutive randomized clinical trials (RCTs). Objectives The primary objective of these RCTs will be to evaluate the capacity of preventing tooth staining, associated with the use of a chlorhexidine mouth rinse, adjunctive to subgingival instrumentation (step 2 of periodontal therapy) (RCT #1). As secondary objective, the capacity of eliminating or reducing tooth staining already present will be assessed (RCT #2).
