Hypoxia-inducible factor-1 alpha (HIF-1α) is expressed as an adaptive response to hypoxia, mediates angiogenesis through the expression of vascular endothelial growth factor (VEGF) and can be induced by tumor necrosis factor-alpha (TNF-α). This study aimed to investigate the gingival crevicular fluid (GCF) and salivary HIF-1α, VEGF, and TNF-α levels in periodontal health and disease. A total of 87 individuals, 20 generalized aggressive periodontitis (G-AgP), 20 chronic periodontitis (CP), 26 gingivitis patients, and 21 periodontally healthy individuals, were included. Clinical periodontal parameters were recorded; GCF and salivary samples were collected; and HIF-1α, VEGF, and TNF-α levels were measured by enzyme-linked immunosorbent assay. Nonparametric tests were used for the statistical analyses. G-AgP and CP groups had significantly higher GCF HIF-1α, VEGF, and TNF-α total amounts than gingivitis and healthy groups (P < 0.05). GCF HIF-1α and TNF-α total amounts in gingivitis group were significantly higher than the healthy group (P < 0.05). GCF and salivary concentrations of biomarkers were similar in both periodontitis groups (P > 0.05). Salivary HIF-1α concentrations in gingivitis group were significantly higher than G-AgP and healthy groups (P < 0.05). GCF HIF-1α, VEGF, and TNF-α total amounts were positively correlated with the site-specific clinical periodontal parameters and with each other (P < 0.05). HIF-1α is detectable in GCF and saliva of periodontally diseased and healthy individuals, and the GCF levels of the biomarker can be affected by disease status. Increased GCF HIF-1α, VEGF, and TNF-α levels in both chronic and aggressive form of periodontitis might suggest the role of TNF-α/HIF-1α/VEGF pathway in the pathogenesis of periodontal diseases.

D010520 Aggressive Periodontitis Inflammation and loss of PERIODONTIUM that is characterized by rapid attachment loss and bone destruction in the presence of little local factors such as DENTAL PLAQUE and DENTAL CALCULUS. This highly destructive form of periodontitis often occurs in young people and was called early-onset periodontitis, but this disease also appears in old people.

D005883 Gingival Crevicular Fluid A fluid occurring in minute amounts in the gingival crevice, believed by some authorities to be an inflammatory exudate and by others to cleanse material from the crevice, containing sticky plasma proteins which improve adhesions of the epithelial attachment, have antimicrobial properties, and exert antibody activity.

D014409 Tumor Necrosis Factor-alpha Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.

D016022 Case-Control Studies Comparisons that start with the identification of persons with the disease or outcome of interest and a control (comparison, referent) group without the disease or outcome of interest. The relationship of an attribute is examined by comparing both groups with regard to the frequency or levels of outcome over time.

D042461 Vascular Endothelial Growth Factor A The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.

D055113 Chronic Periodontitis Chronic inflammation and loss of PERIODONTIUM that is associated with the amount of DENTAL PLAQUE or DENTAL CALCULUS present.
