Active clinical trials for "Periodontitis"

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.

Periodontal disease is an infectious pathology that consists of the destruction of the gums and supporting structures around the teeth. There are several mechanisms involved in this process. In healthy conditions there is a balance between the bacteria present in the gums and the defence mechanisms of the host to fight the disease. One of the substances involved in favouring this protective mechanism is a peptide called LL-37. The aim of this study is to find out more about the rol of this peptide during this process by using a non invasive method of analysis consisting of analysing some samples of the fluid existing between the gums and the teeth. This clinical study will take place at the University Clinic at the University Rey Juan Carlos, Alcorcon (Madrid), Spain. Patients that attend the clinic suffering from gum disease will be offered the possibility to participate in this study. A full questionnaire indicating the risks and benefits of participating in the study as well as the management of confidential personal data will be discussed with the participants in full detail. Full consent will be sought before commencing the study. Firstly, all participants will receive a through periodontal (gum) examination to assess if they suffer from periodontal disease and to what extent (severity). Based on this preliminary data, patients will be classified in different categories. Patients will be divided in two groups: 30 Healthy patients (no signs of periodontitis) 30 Periodontal patients (subdivided in 2 groups of 30, depending of the severity of their disease: 15 patients with Stage I-II periodontitis (mild/moderate) 15 patients with Stage III-IV periodontitis (severe). The intervention will consist on taking samples of crevicular fluid (the fluid found in the space between the gum and the root of the tooth) to quantify the presence of LL-37 as well as IL-4, IL-6, IL-10, which seems to be associated with the defence mechanisms (immunity) of the host against periodontal disease. These samples will be analysed in the laboratory by using some specific procedure called ELISA. All patients from the test group will receive a basic course of periodontal treatment (root scale and polish), which is intended to remove the bacteria causing the disease from the space between the gums and the roots (periodontal pocket). Samples of crevicular fluid will be obtained before commencing the treatment. After 4-6 weeks, a new periodontal examination will take place to assess if there is an improvement of the condition and also to quantify the levels of LL-37, IL-4, IL-6, IL-10. The findings of this study will help to understand the role of this peptide in the defence mechanism of the host against periodontal disease. This could ultimately serve to develop new therapies that could include the use of this peptide in addition to the routine periodontal treatment prescribed to improve the healing conditions of the patient against periodontal disease.

Periodontal disease is a chronic multifactorial inflammatory disease that affects the soft and hard supporting tissues of the teeth. It is one of the most common oral health problems which 90% of the global adult population has been reported to have some form of the disease. Microorganisms in dental biofilm play a critical etiological factor in the development of this progressive destruction disease, and if left untreated, will eventually lead to tooth loss. Recurrent periodontal disease did occur in treated and well-maintained patients at different time intervals and is a site-specific disorder. Therefore, subgingival biofilm removal during supportive periodontal therapy has become a fundamental part in achieving a stable oral health after completion of active treatment. Subgingival debridement involves various techniques. In recent years, many studies have reported on the effectiveness of air polishing device using different powders versus conventional hand instruments and/or oscillating scalers. However, there is no study evaluating the health economic aspect of these treatment modalities. As development leads to advancement of treatment options, they often involve higher cost than the existing measures. Therefore, besides clinical efficacy, economic evaluation enables health decision makers to allocate limited health resources in a more efficient manner, to ensure best possible outcomes, without neglecting any segment of care.

Vitamin D has been considered to possess anti-inflammatory and antimicrobial activity which may be a link for the known interaction of Systemic Sclerosis (SSc) and coronary heart disease (CHD). This study investigated the association between serum vitamin D levels and SSc and periodontitis in patients with SSc, CP and with CHD. Furthermore, the objective was to determine if periodontitis and CHD had an impact on serum vitamin D levels.

INTRODUCTION Orthodontic treatment objectives are achieved through the movement of teeth with the application of an external physical force. It takes around 2 to 3 years to finish the treatment.The most common complications associated with orthodontic treatment are Pain Prolonged duration Gingival and Periodontal complications So orthodontists, clinicians and researchers are always looking for some non-invasive and reliable techniques to minimize the possibility of occurrence of these complications. General objective The prime aim of this research is to study the effect of LLLT on tooth movement,pain, gingival and periodontal complications associated with tooth movement in initial phase of orthodontic treatment. Design of study This will be an experimental; case controlled study utilizing Low Level Laser Therapy in arch form of application.Anterior teeth segment of the maxillary jaw will be treated with LLLT in one group and other group of patients considered as control. Study population and samples This research will be conducted among Pakistani subjects who will be going for fix orthodontic treatment. Research subjects will be gathered from Aga Khan Hospital for Women Karimabad A secondary hospital of Aga Khan University Hospital of Karachi Pakistan. The duration of the study will be six months in which each patient will avail their regular follow up orthodontic treatment visits at every three weeks LLLT will be applied at every visit i.e. 0, 1, 2, 3, 4, 5 and 6th visits on anterior segment of the maxillary jaw in one group of patients, while the other group of patients will be controlled. The clinical parameters gingival index (GI), Bleeding on Probing (BOP), Probing Depth (PD) and clinical attachment loss (CAL) for the research will be recorded at 0, first, third and sixth visit. Study models to determine tooth movement will be taken in all visits from 0 to 6th visit. A Per forma to record the level of pain has been designed which will be given to all the patients at 0 to sixth all visits to record the pain intensity. Data will be recorded simultaneously. Sample frame The sample frame of patient recruitment for this research will be consisting of patients who will sign consent for this research and fulfill the inclusion and exclusion criteria. Sample size will be comprised of 88 pre-orthodontic patients, with an age range of 18 to 30 years. Sample size calculation Sample size will be determined by using PS software (version 3.1.2). To avoid individual variations, the patients will be divided into two groups randomly, using computer generated random numbers. Microsoft Excel 2013 will be used for group randomization. Group A and B will comprise of 36 patients (18 males and 18 females in each group) respectively and only Group A will receive LLLT on anterior segment of the maxillary jaw. However 20% drop out is considered which makes the sample size of 44 in each group at the beginning of study. Research tool The duration of the study will be 6 months in which each patient will visit on their regular follow up orthodontic treatment visits at every 3 weeks. LLLT will be applied at every visit i.e. 0, 1, 2, 3, 4, 5 and 6 months in patients of Group A. The clinical parameters Gingival Index, Bleeding on Probing (BOP), Probing Depth (PD) and Clinical Attachment Loss (CAL) for the research will be as recorded at 0, first, third and sixth visit of all patients of both groups. Conclusion The benefits of adopting LLLT (Low Level Laser Therapy) in an arch form in a routine orthodontic practice may enhance the rate of tooth movement, may be helpful to control orthodontic treatment related complications like pain, gingivitis and periodontitis with comfort and without disturbing patient regular recall visits.

soluble urokinase-type plasminogen activator receptor (suPAR) plays a key role in endothelial function and may be a link for the known interaction of periodontitis and cardiovascular disease (CVD). The investigators compared the impact of gingival health, periodontitis (CP), CHD or of both diseases (CP+CHD) on saliva and serum suPAR levels.

Interleukin (IL)-32, which has been recently reported to be associated with periodontitis, has been suggested to have pleiotropic effect due to its 9 different isoforms. The aim of this study was to investigate the levels of IL-32α, IL-32β, IL-32γ, IL-32δ isoforms in gingival crevicular fluid (GCF) and plasma before and after nonsurgical periodontal treatment in patients with periodontitis (P).Twenty-seven P and 27 periodontally healthy controls (C) were recruited in this study. Periodontitis patients were performed nonsurgical periodontal treatment. GCF and plasma sampling and clinical periodontal parameters were evaluated before and 1 month after treatment. Enzyme-linked immunosorbent assay was used to analyze the levels of IL-32α, IL-32β, IL-32γ, IL-32δ isoforms in GCF and plasma samples.

Metrnl has proven to be an inflammatory-related immunoregulatory cytokine and shown to play a role in the pathogenesis of human inflammatory diseases. Metrnl is highly expressed from the oral mucosa to the esophagus. Periodontitis is a chronic inflammatory disease that can start with localized inflammatory reactions created by the supporting tissues surrounding the teeth against microorganisms and then result in loss of teeth. The authors think that Metrnl may play a role in the periodontitis. The aim of this study is to compare the Metrnl, TNF-α, IL-1β, TGF-β, IL-10 and VEGF levels of healthy and periodontitis individuals.

The aim of this study is to evaluate the accuracy of pulp test in teeth presenting with deep periodontal pocket. The null hypothesis is no significant effect of periodontitis on the accuracy of pulp test.
