Filter by:Periodontitis is one of the most common oral diseases, which is characterized by alveolar bone resorption and destruction. In China, as a major country in the incidence of periodontitis, there is a huge population of patients with severe periodontitis, and the incidence rate is as high as 12.1-16.1% . Previous studies have suggested that the prevalence and severity of periodontal disease increase with age. However, recent articles on meta analysis and related epidemiological investigations suggest that the prevalence of severe periodontitis does not increase with age, and the prevalence of SP remains at about 10% even in the elderly. In order to comprehensively analyze the risk factors of this population, it is inseparable from the analysis of gene polymorphism. At present, it is considered that the main genes that may be related to the severity of periodontitis are IL-1 α-889, rhIL-talk 1 β + 3953, 6-174, 10-597, CD14-260, CD14-159, MMP1-1607 and so on, which may be related to the severity of periodontitis.
A bulk of observational evidence suggests an association between periodontitis and recurrent vascular events in ischemic stroke survivors. One plausible biological mechanism relies on the systemic inflammatory response posed by periodontitis together with changes in the normal function of the vascular endothelium which might lead to recurrence in these population. A non-pharmacological anti-inflammatory treatment (non-surgical periodontal therapy) has shown to reduce systemic inflammatory markers and improve endothelial function. Therefore, we propose to carry out a 1-year follow-up pilot randomized controlled clinical trial to investigate whether control of local and systemic inflammation as well as improve function of the vascular endothelium can lead to reduce the risk of recurrence in patients diagnosed from ischemic stroke.
Guided tissue regeneration(GTR) uses membranous materials to shield gingival epithelial cells and connective tissue cells which grow more rapidly, creating an effective closed space and time for periodontal ligament cells with regenerative potential, so that new cementum is formed on the root surface and periodontal ligament fibers are embedded, resulting in regenerative healing. In order to improve the effect of periodontal regeneration therapy, as early as 1990s, scholars began to mix platelet concentrate and bone graft in periodontal regenerative surgery to improve the ability of local bone induction and tissue healing. Studies have shown that platelet concentrate, which is rich in a variety of growth factors in autologous blood, can promote soft tissue and bone tissue healing by acting on tissue healing cells (osteoblasts, epithelial cells, connective tissue cells, etc.). It is closely related to periodontal regeneration; the regenerative component of platelet concentrate, growth factor, and the structure of fibrin network containing growth factor are the key to promote tissue repair and regeneration.Modified platelet-rich fibrin (advanced platelet rich fibrin,APRF) and concentrated growth factor (CGF) are the latest generation of platelet concentrates. A number of studies have shown that APRF and CGF contain more cytokines, have a denser fibrin network, and show stronger ability to promote the migration and proliferation of gingival fibroblasts, suggesting that both of them may have better ability to promote bone tissue healing. At present, the latest generation of platelet concentrate has been widely used in implant surgery, but their clinical effects in periodontal regeneration surgery are still lack of conclusive evidence. there is no report on comparing the clinical effects of the two through randomized clinical controlled trials.
The aim of this study is to assess the levels of neuregulin-4 and its receptor ErbB4 in the GCF and saliva in stage III and IV periodontitis patients with and without type 2 diabetes mellitus.
The general aim of this project is to get a better understanding how periodontitis develop in young individuals over time and identify factors that contribute to disease recurrence. The investigators also want to see if Stage and Grade of the periodontal disease has a significant impact on disease progression. In addition, another purpose is to identify factors explaining why certain young patients with periodontitis interrupt the periodontal treatment. The specific aims of the project are: - To study the periodontal status and the degree of disease progression over 10 years for young individuals with periodontitis at age < 36 yrs at baseline (study 1) - To identify factors with a significant influence on periodontitis progression for young individuals with periodontitis at baseline (study 2) - To identify explanatory factors to discontinuation of periodontal treatment (study 3) - To identify bio marker and microbiological profiles in young individuals in relation to stage and grade of periodontitis (study 4) Significance: A high patient compliance rate and effective supportive treatment to prevent periodontitis progression are crucial conditions for the long-term prognosis. The identification of factors influencing the compliance rate can improve the frequency of individuals following a supportive care program. In addition, long-time follow-up studies of individuals with the diagnosis severe periodontitis at young age are lacking as well as deeper knowledge concerning risk predictors for further disease progression. The identification of biomarkers or microorganisms that can differentiate between different stage and grade of periodontitis could make it possible to identify individuals with a high risk for disease progression at an early stage.
The present study evaluated clinically the effects of a probiotic on oral microbiota and glycemic control in T2 diabetic patients with periodontal disease. The study was designed as a prospective randomized, double-blind, placebo- controlled interventional study. At baseline and at the end of the 30 day- probiotic period, all clinical, microbiological, and biochemical measurements were tested. Colony counts of oral microbiota, blood fructosamine levels and CRP were the outcomes of the study.
Periodontitis is an infectious disease that causes destruction of periodontal tissues with complex etiology that develops due to local and systemic factors. Host-derived enzymes, cytokines and proinflammatory markers are the main elements that play a role in this degradation. New techniques such as non-surgical or surgical methods combined with laser application are used for its treatment. The subjects were divided into two groups as "Individuals Applied with Diode Laser in Addition to Non-Surgical Periodontal Treatment" (Laser group) and "Individuals with Non-Surgical Periodontal Treatment (SRP)" (Control group). While only non-surgical periodontal treatment was applied to individuals in the control group; In the laser group, diode laser was applied in addition to this treatment. All individuals were examined 1 and 3 months after treatment.The scaling root planing (SRP) procedure was performed mechanically with gracey curettes under local anesthesia. The diode laser applied to the study group was applied parallel to the gingival sulcus at 0.80W power, 940 nm wavelength and 0.80 J / s energy level in continuous phase. Gingival crevicular fluid (GCF) samples were taken without any procedure in order not to change the amount and content. All clinical parameters were also measured by the same investigator before SRP and in all participants. After this treatment, the participants were re-examined in the 1st and 3rd months for control purposes and GCF samples were taken from the same regions again and the clinical parameters were measured again by the same researcher. GCF samples were stored at -20 degrees Celsius until ELISA studies were performed. Clinical parameters (pocket depth, clinical attachment loss, bleeding on probing, gingival index, plaque index) and gingival crevicular fluid (GCF) sampling were obtained at each control. IL-1β, IL-10, IL-17, OPG, RANKL, TWEAK, Sclerostin levels in GCF samples were measured with ELISA method. The aim of this study is to evaluate the effectiveness of diode laser application in addition to non-surgical treatment in periodontitis treatment clinically and biochemically and to assess the potential biomarkers for use.
Type 2 diabetes mellitus is a metabolic disorder. There is a bidirectional association between periodontal disease and DM. Currently there is no data relationship between CSF-1 and IL-34, periodontal disease and diabetes.The aim of this study to investigate GCF levels of IL-34 and CSF-1 in periodontitis subjects with diabetes.
Background; A new mouth rinse formulation ("Lacer Oros Acción Integral", Lacer SA, Barcelona, Spain) has been recently proposed, including O-Cymen-5-ol, potassium nitrate, zinc chloride, dipotassium glycyrrhizate, sodium fluoride, panthenol and xylitol, within its ingredients. Thus, it may be relevant to test the efficacy of this new "Lacer Oros Acción Integral" mouth rinse formulation in a RCT. Primary Objective: The primary objective of this RCT will be to evaluate the antiplaque/antigingivitis effects of the test mouth rinse. Population: Consecutive subjects in supportive periodontal therapy (SPT) will be screened at the Post-Graduate Periodontal Clinic in the University Complutense, Madrid, and enrolled in the clinical trial if they are periodontitis patients, already enrolled in a SPT, for at least 6 months, systemically healthy, with moderate gingival inflammation and complains of dentin hypersensitivity. Study design: pilot, parallel, double-blind, randomized, placebo-controlled, 12-week, clinical trial Intervention: The experimental group will use three times daily a provided manual toothbrush with a sodium fluoride dentifrice, followed by the use of the test mouth rinse (Lacer Oros Acción Integral - new formula, Barcelona, Spain). The control group will use three times daily a provided manual toothbrush with a sodium fluoride dentifrice, followed by the use of the control mouth rinse (Lacer Oros Acción Integral - new formula, without active ingredients, Barcelona, Spain). Visits: Screening, baseline, 2 and 12 weeks. Outcomes: Periodontal clinical outcomes (plaque levels, gingival condition, probing pocket depth), Stainign, Microbiological outcomes (culture and qPCR). Patient reported outcomes, compliance, adverse effects.
The neurological disorders that accompany aging represent a major public health problem. The management of these diseases is a major medical and social priority. This project is based on the assumption that the oral cavity represents a privileged observation space to address these issues. The mouth is a site of easy access for painless sampling; there is therefore a major interest in identifying early oral infectious markers of the development or evolution of senile dementia. In addition to the interest of an early oral diagnosis, the mapping of the oral microbial flora in the demented elderly would allow a better understanding, prevention or even control of the evolution of neurodegenerative diseases. The final objective of our approach is to characterize the oral pathogens, or more probably the group of oral pathogens, which are significantly associated with Alzheimer's disease.
