RESUMEN
Objective: To compare the prostaglandin E2 (PGE2) levels of gingival crevicular fluid in generalized chronic periodontitis between healthy and type 2 diabetic patients. Material and Methods: 56 diabetic and non-diabetic participants with generalized chronic periodontitis were selected randomly. They were divided into two groups (G1: generalized chronic periodontitis patients with normal blood sugar; and G2: generalized chronic periodontitis patients with diabetes). Gingival crevicular fluid samples were obtained from both groups. The average of 2 samples per day were centrifuged in a laboratory at 2500 rpm and temperature of 4°C for 5 minutes and placed in a refrigerator at -20°C. The level of PGE2 was measured using ELISA and Abcam kit. Data were analyzed by Kolmogorov-Smirnov, Mann-Whitney U Test, Pearson and independent T tests. The significant amount was considered 0.05 in this test (α<0.05). Results: The mean level of PGE2 was significantly different in the two groups and the mean level of PGE2 in the control group was lower than the case group. There was no statistically significant relationship between PGE2 with pocket depth, fasting blood sugar (FBS) and HBA1C (p>0.05). Conclusion: PGE2 level of diabetic patient group with chronic generalized periodontitis was significantly more than non-diabetic group with generalized chronic periodontitis.
