Active clinical trials for "Periodontal Diseases"

The PREMIERS study is a proposal for conducting an adequately powered two center phase III randomized controlled trial to test whether intensive periodontal treatment reduces the risk of recurrent vascular events among ischemic stroke and TIA survivors. The study uses the resources in both states including established dental centers, Joint Commission Certified Stroke Centers, the Schools of Public Health, and the Institute for Partnerships to Eliminate Health Disparities. The proposal addresses specific issues with regards to recruitment of African-American and rural stroke/TIA patients advocating the use of culturally appropriate strategies to educate the study subjects regarding stroke, periodontal disease and the periodontal stroke link. The study proposes to utilize economic evaluation of the periodontal intervention from the budgetary perspective. The focus will be on the financial sustainability of providing aggressive periodontal therapy (with certain, although relatively low expenditures) in exchange for a reduction of uncertain recurrent vascular events that may require high cost emergency department utilization and/or inpatient care. The sustainability of the proposed intervention after the completion of the project is integrally linked to the health economic assessment to show the health care cost savings. By integration with a rural primary care center, with an African American majority and households with average incomes below the state average, the study ensures that the proposed intervention to reduce stroke disparity is applicable to this target population.

The aim of the study is to investigate, in an Australian population of pregnant women, whether the treatment of periodontal disease during pregnancy prevents pre-term birth and other complications of pregnancy. Dental screening and periodontal treatment protocols have been based on standard techniques employed by hygienists that can be readily applied to the general obstetric population.

This study will examine the composition of dental plaque-a naturally occurring substance that sticks to the teeth and can cause tooth decay and gum disease. A better understanding of how plaque builds up in the mouth may help in developing improved ways of controlling it. Healthy normal volunteers between the ages of 18 and 65 who work at the National Institutes of Health main campus in Bethesda, Maryland, may participate in this study. Candidates will be screened for eligibility with a medical and dental history. This study involves a maximum of five visits to the dental clinic. At the first visit, participants will have a dental examination, and a mold will be made of the mouth. To make the mold, a small plastic tray containing impression material will be placed in the volunteer's mouth and held in place for about 2 minutes to set. The tray will then be removed and a mold will be made from the impression. The mold will be used to make the mouthpiece used in study 1, described below, and the tooth fittings used in study 2, also described below. Volunteers will participate in one of these two studies. Study 1. Volunteers in study 1 will have their mouthpiece checked at the second visit, have a teeth cleaning, and have the mold put in place. The mouthpiece will be worn for up to 8 hours, during which time soft foods can be eaten. Mouthwash should not be used while the device is in place. At the volunteer's third (last) visit, the mouthpiece will be removed and the volunteer will spit into a tube to collect saliva for examination for bacteria. Study 2. Volunteers in study 2 will have their teeth cleaned at the second visit and the tooth fittings placed onto the back teeth with a dental adhesive. The fittings will be worn for up to 72 hours, during which time volunteers can eat a regular diet and brush their teeth. Mouthwash should not be used while the fittings are in place. At the third, fourth and fifth visits, some of the fittings will be removed and, if necessary, the tooth surface will be polished. The last of the fittings will be removed at the fifth visit and the volunteer will spit into a tube to collect saliva for examination for bacteria.

Cervitec, a chlorhexidine based varnished has been proven to reduce caries risk in younger populations. This study wants to investigate if the use of this product would reduce the risk of losing abutment teeth on patients that are wearing partial dentures as the literature has proven that these teeth are more prone to caries and periodontal disease. The primary objectives of this research project are to: Assess if the topical application of CHX/thymol varnish every three months on partial denture abutment teeth results in a clinicallu significant decrease in any loss of attachment compared to no application, and Assess if the topical application of CHX/thymol vanirhs every three months on partial denture abutment teeth results in a clinically significant decrease in carious lesion development or progression compared to no application. The secondary objectives of this research project are to: 1. Assess of the topical application of CHX/thymol varnish every three months on partial denture abutment teeth compared to no application results in a clinically significant difference in: Bleeding on probing (BoP). Plaque formation. Periodontal pocket depths. Microbial composition and GCF cytokine profile of the sub gingival environment. The patients self perception of oral health.

To determine the relationship between periodontal disease and upper genital tract inflammation in pregnancy. To determine whether certain fluid levels in the oral cavity and the vagina are associated with preterm birth or low-birth weight.

This is a pilot study to determine whether knowledge gained by an individual of genetic risk for severe periodontitis changes the patient's health behavior as measured by an increased frequency of their preventive dental office visits. In addition to the primary objectives of the study, the overall design and logistics will be used to inform a possible future study.

Cardiovascular disease is one of the leading causes of death in the United States and the world. Many interventions relating to prevention have been emphasized as more risk factors for this devastating disease are discovered. Periodontal disease is known to have a close association with cardiovascular disease, but its role as a risk factor is still not well understood. Inflammation is a driving force in both of these diseases, creating a potential bridge between the two. Specifically, periodontal disease can cause an inflammatory reaction in the body, which may predispose or even directly contribute to atheroma formation in the coronary arteries. In this study, the investigators will study the link between the inflammatory state of the body and will search for a correlation with levels of coronary artery disease and periodontal disease. Inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), and immunoglobulin G (IgG) levels in the patient's blood will be analyzed and correlated to clinical attachment loss measured via pocket depth measurement, the distance from the gingival margin to the base of the pocket. A definitive link between these disease processes will allow preventive measures to be taken earlier to prevent this lifelong disease.

The aim of the study was to evaluate if there were differences in oral findings between patients diagnosed with allergic rhinitis and/or asthma and a control group of health people.

Epidemiological studies have suggested that maternal periodontitis affects the fetal-placental unit, with an increased risk of adverse pregnancy outcome. Indeed, it has been suggested that the direct or indirect action of parodontopathogenic bacteria induces an inflammatory cascade that leads to spontaneous premature labor. Also, non-treatment of caries and periodontal disease can lead to acute pain and stress. This may promote self-medication and the inappropriate use of analgesic medications, potentially harmful to the health of the fetus. As part of the prevention of complications of pregnancy associated with oral diseases, the National Agency for Accreditation and Evaluation in Health (ANAES) has set up a system that allows any pregnant woman to consult between the 4th and 7th month of pregnancy, an oral health professional to carry out a complete assessment and free care. This study aims at evaluating this device among pregnant women and healthcare professionals 4 years after its implementation. On the other hand, it will make it possible to look for a possible link between the realization of an oral prenatal follow-up and the outcome of the pregnancy.

The use of CBCT/CAD and PDIP technology makes it possible to determine the gingival and the periodontal phenotype, and it can be useful in establishing treatment plan in which it is required to carry out radiological diagnostics. Assessment of the periodontal and the gingival phenotype in a patient using the method based on CW/CL ratio is unreliable. Determining it for each dento-gingival unit is the appropriate method. Positive correlation between FGT, WKT and AC-GM distance confirms the purpose of measuring these parameters for evaluation of the gingival phenotype and additional TLPAC2 for the periodontal phenotype.
