Filter by:The purpose of this study is to compare the Laser Assisted New Attachment Procedure (LANAP protocol) using the Free-running (FR) Pulsed Neodimium: Yttrium aluminium garnet (Nd:YAG) laser to Scaling and Root Planing (SRP) alone, Modified Widman Flap (MFF) surgery, and Coronal Debridement (CD) alone with respect to periodontal clinical attachment level gain.
Diabetes is a metabolic disorder that affects the uptake of glucose into cells. This causes a cascade of systemic alterations that may lead to kidney failure, cardiovascular complications, altered tissue healing, retinopathies and gangrene. Diabetes is also associated to increased susceptibility to infections and inflammation. It has been observed that diabetic patients suffer more often from oral infections such as periodontal disease. Periodontal disease is an infectious-inflammatory disease that leads to destruction of the surrounding tissues of the tooth. It is proposed that the mechanisms responsible for systemic complication are implicated in the development of periodontal disease. This has been evaluated in studies where diabetic patients showed increased levels of inflammatory cytokines, subgingival bacteria and limited response to treatment. Its has also been suggested that established periodontitis in the diabetic patient leads to insulin resistance due to infection and liberation of cytokines from periodontal tissues and thus worsening the diabetic condition. This study is aimed to establish the response to periodontal treatment with antibiotics and the kinetics of glucose levels in diabetic patients.
The purpose of this study is to assess the efficacy and the safety of Chlorhexidine Gluconate Chip (PerioChip®) in frequent treatment versus routine treatment in therapy of adult chronic periodontitis.
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.

The primary aim of the current study was to determine the association between halitosis detection (presence or absence) and periodontal status in non-smoking subjects, and also assess whether halitosis recordings were related to periodontal clinical parameters, tongue coating and quantities of two putative periodontal pathogens on the posterior region of the tongue determined by real-time PCR. Secondary, halitosis recordings were compared among subjects with chronic periodontitis, chronic generalized gingivitis and periodontal health.
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.
Periodontal disease is a bacterially-induced inflammation. As such, it can become a point of entry of bacteria, toxins and cytokines into the systemic blood circulation, thus adversely affecting the function of kidneys. This is turn can aggravate the condition of patients with CKD. The study hypothesis is that periodontal therapy can improve renal function in patients with CKD and lower the blood levels of markers for systemic inflammation.
This study tries to determine whether the additional use of laser with "cleaning" (known as scaling and root planning) will result in the reduction of inflammation, reduction of bleeding upon examination and reduction of pocket depth in patients who are being maintained on a regular basis but have pocket depths that are ≥5mm with bleeding. When a pocket is bleeding, it is inflamed. It is usually "cleaned" with periodontal instruments (root-planed) to establish health. Some research also advocates using laser therapy to treat a bleeding pocket. Laser therapy is presently being performed in some dental offices and dental colleges. This research is trying to see if the additional laser therapy is beneficial.
