Filter by:Background Increased levels of C reactive protein (CRP) can be found not only within individuals with periodontal diseases and those with atherosclerotic alterations but also have been proved in men with erectile dysfunction (ED). NO seems to be the key mediator in the endothelial-derived vasodilation and penile erection. The incidence of ED increases in patients with diabetes, hypertonia, hypercholesteremia, cardiovascular diseases and renal failure. First evidence suggests that there is a relationship between periodontal disease and ED as well. Due to slow progression of chronic periodontal disease (0.3-0.5mm attachment loss/year) it can be assumed, that periodontal disease exists mainly before ED develops. Specific Aims This cross-sectional study aims to assess the incidence of periodontal disease in male individuals with ED. A possible correlation between severity of periodontal disease, level of systemic hs-CRP and ED will be assessed. Additionally, further risk factors for endothelial dysfunction, such lipid values, will be determined and regarded in the analysis. Hypothesis The investigators assume, that severity of ED correlates with severity of periodontal disease as well as with systemic involvement assessed by CRP-levels. In detail, the investigators hypothesize, that severity of ED (assessed by the questionnaire "International Index of Erectile Function") correlates with the mean probing depth and the level of systemic hs-CRP. Material and Methods 1. st appointment: In the present cross-sectional study 100 male patients with ED will be included. Patients who visit the urological department (Rudolfstiftung) for ED-treatment will be asked to participate. The erectile dysfunction will be assessed by means of a questionnaire (International Index of Erectile Function - IIEF-5). Urologic examination. The following blood parameters will be assessed: testosterone, prolactin, hs-CRP, tumor necrosis factor (TNF)-alpha, Interleukin-1, total cholesterol, LDL, HDL, HbA1c and fasting glucose. 2. nd appointment: At the department of Oral Surgery (Bernhard Gottlieb School of Dentistry) the periodontal situation and the index of decayed-missing-filled permanent teeth (DMFT) index of the patients will be determined. A panoramic radiograph for assessment of alveolar bone loss and a periodontal status (probing depth, recession, bleeding- and plaque-indices) will be performed. The observer at the dental clinic will have no information on the severity of the ED (observer blinded).
White blood cell membrane and surface structures are affected by the metabolic disorders and complications found in diabetes mellitus. Therefore, cellular activation, signal propagation, intracellular signaling as well as bactericidal effector functions are altered. When diabetic symptoms are corrected by the systemic intervention and treatment of the patients (Anti-diabetic Therapy/ADT, i.e. anti-diabetic medication, diet and dietetic supervision, physiotherapy and physical exercises), white blood cell functions will then normalize and reach the functionality comparable to those cells derived from healthy subjects. Gum diseases like periodontitis have long been associated with and termed complications of uncontrolled diabetes mellitus. Vice versa, after diabetic conditions are corrected, periodontitis treatment will be proven effective, when oral hygiene regimen, full mouth decontamination (FD, i.e. the oral use of topical antiseptics prior and after professional mechanical tooth cleaning, tooth as well as root surface planing, polishing as well as gum and soft tissue decontamination in combination with systemic antibiotics) are performed. To reinforce gum healing, reinfection prevention (RP) as well as supportive periodontal therapy (SPT) will be administered by dental professionals on an individual basis and a detailed schedule. If periodontal pockets critical for participant's self care are not eliminated by FD including RP and SPT, and niches >5mm after 6 month persist, patients are informed and offered surgical intervention as indicated for gum disease elimination. Dental follow up exams will be offered to all participants.
Randomized controlled clinical trials have demonstrated that the use of amoxicillin (AMX) and metronidazole (MTZ) as adjuncts to mechanical therapy improves the clinical and microbiological outcomes of scaling and root planing (SRP) in non-smokers and smokers with ChP. However, the effects of this antibiotic protocol have not been directly compared in non-smokers and smokers. Therefore, the aim of this study will be to compare the clinical and microbiological effects of the adjunctive use of MTZ+AMX to SRP in smokers and non-smokers subjects with chronic periodontitis (ChP). It was hypothesized that non-smokers would benefit better from this combination of therapies than the smokers.
Children often damage their front teeth. In approximately 6% of cases, the nerve inside the affected tooth dies (becomes 'non-vital') and natural root development stops. In these cases, the tooth requires a root canal treatment in order to prevent problems such as pain and dental abscesses from arising. However, because the roots of these young teeth are not fully formed, they are weaker and prone to fracture. In addition, root canal treatment is difficult because a root canal filling cannot be placed in a tooth which is not yet fully formed, due to the fact that the root has an 'open' end. To enable root canal treatment to be carried out, a 'barrier' must be placed at the end of the 'open' root. This can be done using materials called Calcium Hydroxide or Mineral Trioxide Aggregate (MTA). These materials are placed inside the root and sealed into the tooth. However, although they help to provide a barrier, they do not help to strengthen the walls of the root. Treatment with these materials requires multiple visits to the dentist, over a period of up to 18 months. There is evidence to suggest that an alternative treatment involving 'revascularisation' (recovery of the blood supply to the tooth) and the use of a triple antibiotic paste allows 'natural' root growth to restart, and also strengthens the walls of the root. Treatment can often be carried out in just two visits. The aim of this study is to discover whether there is a difference between one of two methods of treating non-vital teeth with open ends. It is thought that there will be no significant differences seen between the results of the two techniques. Children with teeth that fall into this category and require root canal treatment will be given one of two treatments, both of which aim to treat infection, close the root end and to allow healing to take place. Teeth will receive one of the following methods of root treatment: 1. Revascularisation (recovery of the natural blood supply to the tooth) following placement of an antibiotic paste into the tooth root. The aim of this treatment is to allow 'natural' root growth to restart. Root growth will allow the tooth to form at barrier at the end of the root. No root canal filling will then be necessary. 2. Closure of the open root end by placement of an artificial barrier at the end of the root so that a root canal filling can then be placed. This will be done with a dental material called Mineral Trioxide Aggregate (MTA). Non-vital teeth with an open end are routinely treated in this way at Liverpool Dental Hospital.
The investigators hypothesized that the IL-1A (+4895), IL-1B (+3954), and IL-1RN gene polymorphisms may be associated with PLBW. Smoking has been well documented by numerous studies as a major environmental risk factor for periodontitis and adverse pregnancy outcomes. Therefore, the investigators only selected non-smoking individuals in this study as the smoking-related risk could obscure the polymorphism-related increase in risk for periodontitis and adverse pregnancy outcomes. This study aimed to determine the association between IL-1A (+4895), IL-1B (+3954), and IL-1RN polymorphisms with adverse pregnancy outcomes and periodontitis in a non-smoking Turkish population.
The purpose of this study is to determine if a topical, adhesive patch (PeriZone PerioPatch) applied to the gums after a deep tooth cleaning (scaling and root planing) reduces the signs of advanced gum disease (chronic periodontitis) more than the deep tooth cleaning alone. Eighty patients with advanced gum disease will be recruited and treated within this clinical trial. Patients will be evaluated for changes in gum measurements over a 12-week period.
Rheumatoid arthritis and periodontitis are two inflammatory diseases that share many pathophysiological similarities as some inflammatory mediators like TNF-alpha, IL-1, Il-6, Il-17, Il-12 et Il-17, RANK-L, or OPG The most severe or progressive forms of rheumatoid arthritis require in 10-30% of cases, the use of biotherapies such as anti-TNF-alpha, anti CD-20 and anti-lL-6. All these treatments results in, among other things, an increased risk of infection, both viral and bacterial. These new biotherapies could have an impact on periodontal status - either by favouring sub gingival colonization of root surfaces by periodontal pathogenic bacteria and initiate periodontitis or exacerbate pre-existing periodontitis, - or a positive modulation of the host response by inhibiting bone resorption of the alveolar process. To date, very few studies have been conducted on this subject which is really a translational research, involving several medical specialties.
Revascularization is an alternative new treatment of immature permanent teeth with necrotic pulp nowadays while apexification is the traditional therapy. The investigators suppose that revascularization is superior to apexification at developing the root of immature permanent teeth and reducing the risk of root fracture,and the research is designed.
Characterization of green propolis and development of mouthwash containing propolis to control plaque and gingivitis. A Phase I.
1. Our hypotheses on the relationship between periodontitis and AS are as follows; - The prevalence of periodontitis is higher in AS patients group than that of non-AS control group - Anti-TNF-α therapy would favorably affect the disease course of periodontitis. 2. Based on our hypotheses, the specific objectives of the present proposal are as follows; - The primary objective is to compare the prevalence rate of periodontitis between AS patient group and non-AS group. - The secondary objectives will be: - To observe the carriage rate of P. gingivalis in AS and non-AS groups - To identify clinical parameters associated with the severity of periodontitis in AS group. - To compare the progression of periodontitis at weeks 12 and 24 between AS and non-AS groups or between AS patients with and without anti-TNF-α treatment
