It has been demonstrated that diabetes mellitus (DM) may have an inductive effect on the vascular endothelial growth factor (VEGF) levels of periodontium during periodontal disease. The aim of this study is to confirm this phenomenon, investigating whether it is also valid for diabetic periodontitis patients under good metabolic control. Sixteen type II DM patients, all with a glycosylated hemoglobin (HbA1c) value less than 7 (test), and 15 systemically healthy (control) chronic periodontitis patients were included in the study. The VEGF concentrations in the gingival supernatants and gingival crevicular fluid (GCF) samples of the study groups were measured by enzyme-linked immunosorbent assay. The data were analyzed by Student's t test in statistical means. The VEGF levels were significantly higher in the gingival supernatants of the test group (55.89 +/- 8.11 pg/ml) than that of the control group (24.81 +/- 2.04 pg/ml; p < 0.01). However, there was no statistically significant difference in the VEGF levels of GCF between the study groups (38.96 +/- 4.89 pg/ml in the test and 32.20 +/- 4.02 pg/ml in the control group; p > 0.05). Our study confirms that DM affects the VEGF levels of periodontal soft tissues in periodontal disease, and our results also suggest that this effect may not be influenced by the metabolic control of DM.
