Brief Summary:
Hypoxia-inducible angiogenic pathway involving hypoxia inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF) and tumour necrosis factor- alpha (TNF-α) may regulate the several biological processes related to inflammation. Generalized aggressive periodontitis (G-AgP) is a rare but highly destructive form of inflammatory periodontal disease. The present study aimed to assess the effect of non-surgical periodontal treatment on gingival crevicular fluid (GCF) HIF-1α, VEGF and TNF-α levels in G-AgP patients. 20 G-AgP and 20 periodontally healthy subjects were enrolled. At baseline, GCF samples were collected and whole mouth clinical periodontal parameters were recorded. G-AgP patients received non-surgical periodontal treatment. Clinical parameters and GCF cytokines were re-measured at 1 and 3 months after treatment. GCF HIF-1α, VEGF and TNF-α levels were analyzed by ELISA. Data were analyzed using appropriate statistical tests.
