Filter by:The aim of this randomized clinical trial was to clinically evaluate and compare the healing of intrabony defects after treatment with advanced platelet-rich fibrin (A-PRF+) to enamel matrix derivatives (EMD) in periodontitis patients.
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.
The aim of this study was to assess the efficacy of minimally invasive nonsurgical debridement (MINSD) of periodontal pockets with or without local amino acid buffered sodium hypochlorite (NaOCl) gel application after 6 months follow-up.
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.
The aim of this clinical trial is to investigate the concentrations of Lipocalin-2 and Semaphorin 3A levels in gingival crevicular fluid in subjects with different periodontal diseases. At the same time for the periodontitis group; the purpose of this study is to analyze the correlation of these proteins with clinical parameters at the first and third months after the nonsurgical periodontal treatment.
The aim of this study was to analyze the association between salivary IL-6 levels in patients with periodontitis. Furthermore, the objective was to determine if the periodontitis influenced salivary IL-6 levels
Periodontal disease is amongst the most prevalent oral diseases worldwide and in North America. According to the 2007/09 Canadian Health Measures Survey, 16% of Canadian adults and 24% of older adults, 60 to 79 years of age, were found to have moderate periodontal disease. Moreover, 11% of Canadian adults were found to have calculus scores in the highest range. On the other hand, recent reports on the prevalence of periodontitis in the US showed that 47.2% of adults aged 30 years and older have some form of periodontal disease and 70.1% of adults 65 years and older have periodontal disease. The estimates also showed that the expenditure for periodontal treatments in the US is about approximately $ 14.3 billion. Since dental calculus plays an important etiological role in initiation and progression of periodontal diseases. Investigation and investment on preventive technologies to prevent the periodontal disease are important for any health care system and its end-users. Furthermore, the removal and prevention of dental calculus using an effective toothpaste could reduce the need for professional periodontal interventions or the time of these treatments that in turn reduces their cost and other burdens on patients. The aim of this study is to assess the efficacy of D-Tart toothpaste in removing dental calculus compared to Crest® (Complete Whitening plus Scope, tartar control, Procter & Gamble, Cincinnati, OH), anti-tartar toothpaste with similar pH and texture to D- Tart toothpaste.
This prospective observational study examines the effects of the Covid-19 pandemic on oral health, taking psychosocial factors into account, and the possible impact of a high periodontitis risk on the severity of the need for treatment in Covid-19 patients.
Periodontal diseases are highly prevalent inflammatory diseases. It is now well known that they are correlated with numerous systemic diseases as : diabetes, chronic obstructive pulmonary disease, metabolic syndrome or rheumatoid arthritis. Recently, periodontal diseases have been correlated with inflammatory bowel diseases (IBD). IBD include two types, Crohn's disease and Ulcerative Colitis. It could be a significant risk factor for the pathogenesis of periodontal disease. These diseases present common features : a high prevalence worldwide, multifactorial pathogenies with common mechanisms. To date, no study has linked activity of IBD and periodontal diseases. The authors hypotheses that the prevalence of periodontal diseases could be increased in patient presenting an active IBD
This study compares the efficacy of root coverage achieved by the Pinhole Surgical Technique (PST) technique and the Connective Tissue Graft (CTG) technique in the treatment of Miller class I and II gingival recession defects. All patients will receive PST in one quadrant and CTG in another quadrant. The hypothesis being tested is: Pinhole Surgical Technique outcomes are not inferior to those of the Connective Tissue Graft surgical technique.
