The role of local and peripheral antioxidants in the pathogenesis of chronic Periodontitis in smokers
Chronic periodontitis is one of the most common chronic inflammatory diseases of man and accounts for 60% of tooth loss. It is initiated by the subgingival biofilm and in susceptible individuals an abnormal inflammatory-immune response fails to resolve the inflammation and leads to destruction of …

DARK-PIGMENTED, AMOXICILLIN-RESISTANT, BACTERIAL SPECIES IN CHRONIC PERIODONTITIS MICROBIOTA IDENTIFIED WITH MATRIX ASSISTED LASER DESORPTION/IONIZATION TIME-OF-FLIGHT MASS SPECTROMETRY.
… numbers from the subgingival microbiome of human periodontitis, and are statistically associated with progression of chronic periodontitis. Due to their frequent expression of beta-lactamase enzymes, which hydrolyze and degrade beta-lactam class antibiotics, these species may compromise systemic …

QUANTITATIVE ANALYSIS OF AGGREGATIBACTER ACTINOMYCETEMCOMITANS IN DENTAL PLAQUE SAMPLES OF MOROCCAN SCHOOL CHILDREN WITH AND WITHOUT PERIODONTITIS
… studies reported a relatively high prevalence of periodontitis among adolescents in Morocco. The importance of the composition of subgingival plaque and the presence and proportion of Aggregatibacter actinomycetemcomitans to the total plaque bacteria in the pathogenesis of periodontitis is not …

Prevalence of interleukin-1 polymorphisms and its association with periodontal disease status in the Xhosa population of South Africa
Periodontitis is a bacterially induced chronic inflammatory disease that destroys the supporting tissues of teeth. Clinical observations and experimental evidence indicates that there is a genetic influence of risk factors for periodontitis. A specific pattern of IL-1 polymorphisms (known as the …

Avaliação dos níveis de proteína C-reativa ultra-sensível em pacientes com periodontite crônica severa generalizada e sem periodontite
… patients with and without generalized severe chronic periodontitis. METHODOLOGY: A seccional study was realized using a sample with 62 patients, being 31 participants carriers of periodontal diseases (Group I) and 31 without periodontal diseases (Group II), grouped to the pairs by age and sex. …

Cannabinoid Receptor 2 (CB2) Ligands Downregulate Pro-Inflammatory Markers in Stimulated Primary Human Periodontal Ligament Fibroblasts (hPDLFs)
… 743 million individuals suffering from chronic periodontitis (PD) making it the sixth most prevalent condition worldwide. The affected adult population in the U.S. are nearly 64.7 million and the healthcare costs exceeds $14 billion. Recently, host response to pathogenic infection has …

Proteomic comparison of Amoxicillin resistant and susceptible periodontal Provotella Intermedia and Provotella Nigrescens clinical isolation with Matrix-Assisted Laser Disportion Ionization Time-Of-/flight mass spectrometry
… in the etiology and progression of human chronic periodontitis. Because the bacterial species may not be adequately suppressed in the subgingival microbiota of chronic periodontitis lesions by conventional mechanical root debridement when present in high cultivable proportions, systemic …

Neutrophil extracellular traps in periodontitis
… traps (NETs) in the pathogenesis of periodontitis. A fluorometric assay was developed for the in vitro quantification of NET release and used to assess relative levels in chronic periodontitis patients, indicating elevated release under several stimulatory conditions compared with …

Changes in the Oral Cavity and Common Diseases /// Промени в оралната среда и общи заболявания
… in deep periodontal pockets in adults with chronic periodontitis. In children with renal disease incidence of Candida is higher than in controls. Unstimulated saliva contains viral HBV DNA, but not HCV RNA. Immunity after vaccination for hepatitis B have only 40 percent of children between 6 …

SERUM ANTI-PHOSPHORYLCHOLINE AND ANTI-CARDIOLIPIN CONCENTRATIONS FOLLOWING PERIODONTAL SCALING AND ROOT PLANING
… and IgM anti-CL. To test this, 17 subjects with chronic periodontitis received scaling and root planing in conjunction with blood sample analysis to determine if periodontal instrumentation resulted in changes in these serum antibodies. If plaque bacteria are responsible for an immune response …

Study on porphyromonas gingivalis- and porphyromonas endodontalis- mediated signaling pathway
… of multiple forms of periodontal disease such as chronic periodontitis. However, in order to culture this gram-negative anaerobic microbes in the laboratory we need a long time (about 72 hours) with a complete absence of oxygen (≤0.001%) to reach optimal cell density. Therefore it is usually …

Proteomic Investigation of Salivary Biomarkers in Periodontal Diseases
… concentrations were significantly elevated in periodontitis than in gingivitis or health. LL-37 was significantly elevated in aggressive periodontitis (AgP) compared with chronic periodontitis (CP) and gingivitis/health. Periodontal therapy reduced the salivary levels of HNP 1-3. Diabetes, …

LPS from subgingival plaque and the periodontal pathogen Porphyromonas gingivalis, its effect on M1 and M2 macrophage responses and potential as a biomarker
Chronic periodontitis is an inflammatory disease which, in response to a dysbiotic biofilm results in tissue destruction and ultimately tooth loss. The mechanisms which initiate the disease are poorly understood, as are the effectors which cause periods of exacerbation and remission experienced by …

Association Between Periodontitis and Hyperglycemia and Metabolic Syndrome Components
<p>BACKGROUND AND OBJECTIVES: Adult periodontitis is commonly considered as a chronic inflammatory disease resulting from low-grade oral infection associated with type 2 diabetes mellitus (T2DM). However, its relation including metabolic syndrome and the understanding of biological pathways are …

An investigation of Porphyromonas gingivalis peptidylarginine deiminase: a putative virulence factor in an animal model of inflammation.
… gingivalis, an oral periodontopathogen linked to chronic periodontitis expresses peptidylarginine deiminase (PAD), an enzyme that converts peptide-bound arginine to citrulline. A relationship between human PADs and chronic inflammatory diseases has been proposed. Citrullinated a-enolase is a …

The association between interleukin-1 gene polymorphism and periodontitis in adults in Africa: A systematic review
Background: Periodontitis, a multifactorial inflammatory disease affecting the periodontal tissue, is a global oral health concern. While bacterial infections initiate the problem, the body's inflammatory response impacts disease progression. Interleukin-1 (IL-1), a group of molecules known as …
