Filter by:Pregnancy is a physiological state that is part of the reproductive life of women, establishing their fertile age between 15 and 45 years mainly. This stage will not only mark the birth of the baby but also cause various changes both immunological and physiological, to accommodate the growing fetus. Maternal periodontitis has direct and indirect potential to influence the health of the fetus-maternal unit. According to the literature reviewed, the first evidence that oral bacteria influenced pregnancy outcomes was reported by Collins et al. The injection of P. gingivalis into pregnant hamsters caused intrauterine growth retardation and smaller fetuses, together with an increase in the levels of proinflammatory mediators (IL-1b and PGE2) in the amniotic fluid. Two hypotheses have been pointed out regarding the link between oral health and the adverse outcome of pregnancy. The first states that periodontal disease causes abnormal systemic immune changes, leading to complications in pregnancy. While the second hypothesis suggests that oral bacteria directly colonize the placenta, causing localized inflammatory responses, resulting in prematurity and other adverse outcomes.
This study is a retrospective comparative evaluation of six main periodontal pathogens and total bacterial load in chronic periodontitis patients affected or not by type 2 diabetes mellitus by polymerase chain reaction analysis.
Is the non-surgical periodontal therapy can improve glycemic control in type 2 diabetic patients with chronic periodontitis?
The study is a cross-sectional survey investigating the prevalence of Periodontitis stage III & IV in Egyptian dental patients attending the oral diagnosis clinic at faculty of Dentistry, Cairo University
Sialic acid (SA) is the generic term given to a family of acetylated derivatives of neuraminic acid. SA is a 9 carbon monosaccharide. An important function of host SA is to regulate innate immunity. SA is present in several acute phase proteins which are known to be associated with periodontitis. There exists a need for a biomarker, for early detection of disease evolution and more robust therapy efficacy measurements. Till date, there is very little data regarding simultaneous estimation and comparison of total SA content in saliva. IL-10, an anti-inflammatory cytokine, regulates the synthesis of pro-inflammatory cytokines such as IL-1, -2, -6 and stimulates protective antibody production. IL-10 is expressed in both healthy and diseased human periodontal tissues and is reported to be reduced in patients infected with Aggregatibacter actinomycetemcomitans. The present study was therefore undertaken with an aim, to not only assess the levels of TSA(Total sialic acid levels),but also of IL 10 levels in saliva from stage 1(mild) to stage 2(moderate) periodontitis patients
The present study aims to evaluate photodynamic therapy (PDT) using Zinc oxide as a photosensitizer as an adjunct to scaling and root planing (SRP) in the management of chronic periodontitis.
Aorta Abdominal aneurism (AAA) is a chronic degenerative disorder leading to the dilation and eventually to the rupture of the aortic wall. The pathology presents risk factors such as aging, atherosclerosis, male gender, cigarette smoking, pulmonary emphysema and high blood pressure.The vascular wall destruction is characterized by a remodeling of the extracellular matrix (ECM), the presence of an inflammatory infiltrate of macrophages and lymphocytes associated increase in production of MMPs. A similar destruction mechanisms is found in periodontitis a chronic inflammatory diseases characterized by gram-negative bacteria species that are able to degrade ECM of the tooth supporting tissues and leading finally to tooth loss .Moreover, relationships between periodontitis and cardiovascular disease have already been demonstrated. These associations are considered to be initiated by transient or prolonged bacteremia due to dissemination of oral bacteria or their products into the bloodstream . The periopathogens, more specifically Porphyromonas gingivalis (Pg), were observed in atherosclerosis and aneurysm specimens as well as in coronary heart disease and endocarditis The association between periodontitis and Abdominal Aortic Aneurysms (AAA) has not often been studied especially from a clinical aspect. The mechanisms that induce the initiation, the development or the recurrence and the rupture of AAA after a period of quiescence not well studied and are therefore still unknown. The aim of this clinical observational case controlled study is to search for a possible relationship between periodontal disease and rapid growth of AAA. Patients presenting stable or unstable AAA will be screened for the degree of periodontitis, for the type of oral microbiology and periodontopathogen markers present in the blood stream.
Traditionally, periodontal gum surgery has been used as a method to gain access to inflamed periodontal pockets around teeth. The outcome of these surgeries, however, is not always successful as there can be recurrence of inflammation and disease. The objective of this study is to assess the effectiveness of antimicrobial photodynamic therapy as an adjunct to mechanical debridement of residual periodontal pockets in patients having undergone periodontal surgery. Pocket probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) will be evaluated at all sites as measures of inflammation and disease resolution.
Periodontal Disease (PD) is present in 60+% of adults >65 years and is associated with tobacco smoking, diabetes, and atherosclerosis that worsen inflammation, comorbidities common in older people with mild to moderate cognitive impairment (MCI). Older MCI patients are prone to poor oral hygiene and dental health, which if untreated worsens inflammation-mediated brain and nervous system function, and accelerates progression to dementia. Asymptomatic carotid artery stenosis (ACAS) is often a silent disease detected in only ~10% of older adults, and may have a strong association with MCI. This study examines the effects of intensive therapy for periodontitis on cognition in high-risk older people with ACAS. Results could highlight PD as a readily modifiable risk factor for dementia.
Objective: The aim of this study is to evaluate the effect of HA as an adjunct to scaling and root planning (SRP) on clinical parameters, periodontal inflamed surface area (PISA) and adenosine deaminase (ADA), catalase (CAT), and glutathione (GSH) levels in gingival crevicular fluid (GCF) in patients with periodontitis.
