The etiopathogenesis of periodontal disease results from complex interaction between infectious agents, mainly including bacteria, and host cellular and humoral immune responses. However it is thought that bacteria-induced pathogenesis is not sufficient alone to explain all biological and clinical features of the destructive periodontal disease. The main hypothesis is that herpesviruses, such as Epstein-Barr Virus, may participate as well by altering epithelial gingival cell biology and consequently may promote the initiation and progression of periodontitis.
Recent scientific evidence suggests that the main defence cell of the body (neutrophil) behaves in a different manner in patients with gum disease; namely how they interact with bacteria and their role in defence systems of the body. This study proposes to examine these responses in periodontitis patients and healthy controls. The proposed study will include patients undergoing periodontal (gum) treatment who will be matched to periodontally healthy controls. Blood, gingival crevicular (gum) fluid and clinical measures will be collected both pre- and post-therapy to measure differences in cell behaviour both before, and following routine therapy. Blood samples will be used to isolate peripheral blood neutrophils prior to analysis of their responses to different bacterial stimuli including oxygen radical, cytokine and extracellular trap release. Gingival Crevicular Fluid samples will be used to measure different biochemical markers that result from the production of Neutrophil Extracellular Traps (NETs). Routine clinical measures will be taken both pre- and post-therapy as a measure of treatment response. Patient volunteers undergoing treatment will be asked to donate a total of four small samples of tissue from the gums whilst they are already anaesthetised for routine treatment. These will be approximately the size of a needle head (2mm2mm) and used to examine NET formation within the tissues and related processes. This will provide novel in-vivo data regarding this recently discovered method of neutrophil defence in innate immunity. This proposal represents a novel study aimed at improving our current understanding of why inflammatory periodontitis develops in some patients but not others, as well as providing pointers to causal/noncausal relationships between periodontitis and important systemic conditions such as diabetes and rheumatoid arthritis. Ultimately, novel treatment approaches and primary prevention (for periodontitis) or secondary prevention (for systemic disease) strategies may emerge.
The objective of this study is to determine whether enhanced micronutrient intake in the form of fruit, vegetable and berry juice powder (FVB) concentrate, improves clinical outcomes in chronic periodontitis patients prior to standard non-surgical treatment.
• Background: Peridontitis is a group of diseases with complex bacterial etiology that affects a large proportion of the Chilean and worldwide population. Its treatment, based on an anti-infective mechanical therapy including scaling and root planning procedures, has been highly effective in numerous short and long term clinical trials. The use of adjunctive systemic antibiotics has shown significant improvements in the initial therapy results of specific periodontal disease types or patient profiles. The synergic combination of Metronidazole plus amoxicillin has been widely and successfully used for the treatment of aggressive and severe chronic periodontitis, demonstrating additional benefits in clinical and microbiological parameters over scaling and root planning alone. However, and despite its proven efficacy, there is a lack of evidence that evaluates the impact of antimicrobials intake at different times of the mechanical treatment, emphasizing the necessity of a study that compares, simultaneously, the variation of the adjunctive antibiotic effects when they are administered in different moments through the periodontal therapy course.
Chronic periodontitis is a common infectious disease characterized by progressive attachment loss and alveolar bone resorption eventually resulting in tooth loss. The ultimate goal of periodontal therapy is to prevent this endpoint. At least when a strict supportive care program is implemented following active therapy, subsequent tooth loss is limited to a mean of about 0.1 per patient per year. In contrast, three to six times as many teeth may be lost if the disease is left untreated. The objective of supportive care is to prevent disease recurrence, which is accomplished by strict home care and professional plaque control at regular intervals depending on the patient's needs. Evidently, not all patients are optimally compliant in terms of plaque control. Therefore, chemical aids could be administered to supplement mechanical plaque removal. Essential oils solutions containing menthol, thymol, methyl salicylate and eucalyptol as active agents may be more appropriate to supplement daily home care. Clinical studies have shown an additional anti-plaque and anti-gingivitis effect over mechanical plaque control without relevant side effects in healthy subjects and gingivitis patients. Recently, significant reductions of periodontopathogens in the subgingival biofilm have been shown in periodontitis patients following subgingival irrigation using an essential oils solution. In addition, mouthrinsing on a daily basis seemed to substantially alter the subgingival microflora towards a less pathogenic one in gingivitis and periodontitis patients. Even though these are interesting findings, they should be considered exploratory since they relate to a small number of patients observed for only two weeks. The goal of the present study was to thoroughly document the clinical and microbiological effects of an essential oils solution used on a daily basis for 3 months as an adjunct to mechanical plaque control measures in a large number of chronic periodontitis patients in supportive care.
Cell sheet technique possess the properties of conserving the ECM, rich molecules and retaining cell vitality, and will promote the capacity of cell adhesion and proliferation. The stem cell based cell sheet therapy has been utilized in many fields and scored the satisfactory results. Periodontitis is a chronic disease which causes the destruction of the periodontal tissue and leads to the teeth loss in the end. The routine cell-based therapy to the periodontitis was confronted with many difficulties. In the investigators previous preclinical research, +the investigators fabricated periodontal ligament stem cell (PDLSC) pellets and cell sheet fragment and applied them in the periodontal defect area for tissue regeneration and periodontitis treatment. And the investigators carried out a comprehensive study of the PDLSC allograft. The host responses and implanted cell fates were recorded. After the scientific investigation of the preclinical study, the investigators designed the preliminary clinical trial of PDLSC cell sheet for the chronic periodontitis therapy in the aims to test the PDLSC fates and explore one ideal transplantation mode.
The purpose of the study is to assess efficacy and safety of Flurbiprofen Chip versus Chlorhexidine chip (Periochip®) in therapy of adult chronic periodontitis.
The aim of this study is to verify the efficacy of Photodynamic Therapy (PDT) as an adjunct to non-surgical treatment of chronic periodontitis by assessing clinical and microbiological and immunological parameters. This is a randomized, controlled, double-blind, parallel clinical trial. Thirty eight patients with chronic periodontitis will receive conventional periodontal treatment. After eight weeks, patients will be re-evaluated and sites with residual pockets (PD ≥ 5 mm ) will be selected as experimental sites, and will be allocated to test and control group randomly. The test group will receive the application of PDT and the control group will receive sham procedure. The clinical parameters will be evaluated at baseline, 3, 6 and 12 months after treatment. Subgingival plaque will be collected before PDT, a week after, 3, 6 and 12 months later. The microbiological evaluation will detect and quantify periodontal pathogens such as Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Aggregatibacter actinomycetencomitans with real time-PCR. During follow-up, patients will receive periodontal maintenance every 3 months, as well as the application of PDT or sham
The primary aim of the study is to determine if non-surgical periodontal therapy (scaling and root planing and supportive periodontal therapy) is efficacious compared to delayed therapy in reducing elevated glycosylated hemoglobin (HbA1c) at 6 months post-randomization in subjects with type 2 diabetes and untreated, moderate to advanced chronic periodontitis. The secondary aims of the study are to: 1. evaluate whether 6 month (or shorter-term (3 month)) changes in clinical measures of chronic periodontitis (gingival index, bleeding on probing, probing depth, clinical attachment level) are related to changes in HbA1c and fasting glucose or insulin resistance as measured by the Homeostasis Model Assessment 2 (HOMA2). 2. assess the 3 month and 6 month efficacy of periodontal therapy on all of the above study outcomes. If a treatment response is observed for any of the study outcomes at 3 months, then the trial can evaluate whether this response is sustained at 6 months.
