Active clinical trials for "Periodontitis"

Periodontitis, a known complication of diabetes, is an infectious disease that destroys bone and gums. Studies have shown that diabetes favors periodontitis, and that periodontitis contributes to its aggravation. The positive impact of treating periodontitis on the cost of diabetes care has been demonstrated and the French national health system fully covers the treatment of periodontitis for diabetic patients. Unfortunately, 80% of diabetic patients do not visit their dentist enough. Although diabetologists regularly see their patients and are aware of the importance of treating periodontitis,they do not have the expertise to diagnose the condition whereas a specialist dentist can often diagnose it just by looking. This study aims to develop a solution combining the dentist's expertise with that of the diabetologist. This would be based on analysis of a photograph of the patient's oral cavity, taken in the department. So far, no studies have ever evaluated the performance of an expert dentist for diagnosing periodontitis from a simple photograph made by non-dental experts in a diabetic department. The hypothesis is that the concordance in the diagnosis of periodontitis between an indirect method based on a photograph of the oral cavity and a direct method based on clinical examination of this oral cavity (reference) in the diabetic patient would be satisfactory.

This study is about the assessment of two oral telemedecine tools compared to an intra oral clinical examination used as a reference among elderly persons living in nursing home. Our hyposthesis is that the diagnostic performance of the two devices will be similar. The main goal of the study is to assess the performances of two intra-oral cameras compared to an intra oral clinical examination to detect at least one decayed tooth. The secondary objectives of this study are : At patient's level: To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) at least one filled tooth, (ii) at least one missing tooth, (iii) gingivitis, (iv) an abscess, (v) dental plaque and (vi) calculous To assess the concordance between each intra oral cameras and the intra oral clinical examination in the evaluation of the number (i) of decayed teeth, (ii) filled teeth and (iii) missing tooth From video acquisitions of each intra oral cameras, to assess the inter-observer concordance for the diagnostic of each dental pathologies (presence of at least one decayed tooth, filled or missing) and periodontal (presence of gingivitis, abscess, dental plaque or scale) From video acquisitions of each intra oral cameras, to assess the inter-observer agreement of the number of teeth: (i) decayed, (ii) filled and (ii) missing At tooth level : To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) a cavity, (ii) a filled tooth and (iii) missing tooth In all patients : To assess patient's feelings about the use of each intra oral cameras To compare the time required for video acquisitions between each of intra oral cameras For patients with dental or periodontal pathologies observed during the intra oral examination: 8 To assess, 2 months after initial evaluation, the proportion of patients attended dental or periodontal care and for which an appointment with a dentist has been scheduled

The purpose of this study is to test whether spraying the tooth of patients by use of the novel electrolyzed water spray will produce improvement in the condition of mild periodontitis.

The aim of the present study is to show that the use of 0.55T MRI combined with a "dental" coil produces images of sufficient diagnostic value to assess areas of interest in dentistry, and to compare MR images to traditional, dental-oriented radiographic images for diagnostic purposes.

The aim of this observational study was to find out the oral status of pregnant women with GDM. The main questions it aims to answer are. What is the oral status of pregnant women with GDM Does GDM cause changes in the patient's oral flora Participants will describe the main tasks that participants will be asked to complete. The researcher will compare the [periodontal health group] to see if there is [different flora].

Periodontitis is a chronic infectious disease characterized by loss of tooth supporting periodontal structures and alveolar bone. In the U.S. and worldwide, periodontitis is the major cause of tooth loss in adults. Type 2 Diabetes mellitus (T2DM) is a complex disease that affects 13-15 million Americans and is associated with a variety of serious complications. T2DM is well established as a strong systemic risk factor for periodontitis. The severity and prevalence of periodontitis is much higher in patients with diabetes. This relationship may be bi-directional.

Periodontitis is an inflammatory pathology that destroys periodontitis and causes tooth loosening. Its high incidence, combined with very high oral and systemic morbidity, places this pathology at the heart of global public health priorities. The current therapeutic management of periodontitis is not satisfactory because it often leads to a stabilization of the disease, marked by frequent recurrences, especially severe forms. Improving the treatment of patients with periodontitis is therefore an essential priority. If gingival bacterial dysbiosis is a major contributing factor, this model has clinical-biological limitations that suggest that other etiological factors are involved, and worsen the pathology. In particular, the literature provides clear evidence that periodontal lesions are mostly infected with Herpes EBV, CMV and HSV-1 viruses and that periodontal infection with these viruses is very directly correlated with disease progression (severity). In addition, our work provides new cellular and molecular data that demonstrate mechanisms of active EBV infection of cells and periodontal structures, and highlight inflammatory and necrotic effects associated with this infection. Given these observations and the high pathogenicity of herpes viruses, all known to be powerful inflammatory, lytic and immunomodulatory agents, it seems difficult not to evoke a direct etiopathogenic role of these viruses capable of acting synergistically with periodontopathogenic bacteria. In this context, the use of an antiviral appears as a very attractive therapeutic proposal to effectively treat periodontitis in combination with conventional treatments. This original and innovative proposal can also be easily and quickly validated in a randomized therapeutic trial through the availability of antiviral molecules that are non-toxic and very specific to human herpes viruses that are derivatives of aciclovir.

This is a Pilot Phase III single-blind randomized controlled clinical trial in patients, aged 18 years and older, presenting with symptoms of apical periodontitis. The overall goal is to assess whether 2% Chlorhexidine (CHX) is superior to Calcium Hydroxide in reducing interappointment pain.

Platelet rich fibrin (PRF) has been widely used in regenerative dentistry since it provides plenty amount of growth factors that enhance wound healing and tissue regeneration. Platelet derived growth factor-BB (PDGF-BB) is a growth factor with essential functions such as regulation of cell migration, proliferation, and differentiation. This study aims to evaluate the efficacy of PRF in improving the clinical periodontal parameters and GCF level of PDGF-BB.

The aim of this study is to assess the levels of neuregulin-4 and its receptor ErbB4 in the GCF and saliva in stage III and IV periodontitis patients with and without type 2 diabetes mellitus.
