Chronic periodontitis is a multifactorial inflammatory disease that affects supporting structures of the teeth. Although the gingival response is largely described, little is known about the immune changes in the alveolar bone and neighboring tissues that could indicate periodontal disease (PD) activity. Then, in this study we identified the ongoing inflammatory changes and novel biomarkers for...

High-throughput sequencing has helped to reveal the close relationship between Prevotella and periodontal disease, but the roles of subspecies diversity and genomic variation within this genus in periodontal diseases still need to be investigated. We performed a comparative genome analysis of 48 Prevotella intermedia and Prevotella nigrescens isolates that from the same cohort of subjects to id...

BACKGROUND Salivary stress-related biomarkers in connection with periodontal disease have not been extensively studied. In addition to cortisol as a well-known marker of stress loading, chromogranin A (CgA) and α-amylase (AA) are supposed to link the activity of the neuroendocrine system to local and systemic immune functions and to be related to periodontitis. This study aims to determine CgA ...

OBJECTIVES Neopterin is a valuable diagnostic biomarker, which is elevated in inflammatory conditions like periodontitis, that is characterized by destruction of the supporting structures of the teeth. Among the biomarkers, neopterin occurs in body fluids, and acts as a diagnostic marker for present and future disease activity. METHODS Thirty female subjects with chronic periodontitis, mean a...

BACKGROUND AND OBJECTIVES The receptor activator of NF-κB ligand-osteoprotegerin (RANKL-OPG) bi-molecular system is the "bottle-neck" regulator of osteoclastogenesis and bone resorption, both in physiological and pathological conditions. This review aims to elaborate the current knowledge on RANKL and OPG in periodontal disease, and to evaluate their diagnostic and prognostic potential as bioma...

primary immune thrombocytopenia is an acquired bleeding disorder with no clinically apparent cause of thrombocytopenia. clinical indicators of itp include easy bruising of the skin, prolonged bleeding on injury, mucocutaneous lesions such as petechiae and ecchymosis, epistaxis, gastrointestinal bleeding, hematuria and bleeding from the gums. it is important for a dentist to be aware of the clin...

background and objectives: gingival and periodontal diseases are associated with specific bacterial infections. the main aim of the study was to know whether the periodontitis is associated with an increased risk for acute myocardial infarction (ami) and to know the distribution of porphyromonas gingivalis in patients with acute myocardial infarction associated with chronic periodontitis and ac...

Migraine is a neurovascular disorder that is characterized by unilateral, pulsatile headaches. Migraine due to its individual and social effects is known as a major cause of disability in the world. The main complication of this disease is chronification that is known as chronic migraine (CM). It seems that several factors contribute to migraine chronification such as age, female gender, obesit...

BACKGROUND Considering the role of matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in the pathogenesis of periodontitis, the present study is to estimate the levels of MMP-3 and TIMP-1 in gingival crevicular fluid (GCF) in periodontal health, disease and to evaluate the effect of periodontal therapy on MMP-3 and TIMP-1 concentrations in GCF.
