PROSTAGLANDIN E2 LEVEL IN GINGIVAL CREVICULAR FLUID AND ITS RELATION TO THE PERIODONTAL POCKET DEPTH IN PATIENTS WITH PERIODONTITIS

摘要

Prostaglandin E2(PGE2)levels in gingival crevicular fluid (GCF)of 46 normal controls and 90 patients suf-fering from periodontitis with different periodontal pocket depths were measured by radioimmunoassay (RIA).The results demonstrated that PGE2 levels in the periodontal pockets are higher in patients with peri-odontitis.The PGE2 level rises as the periodontal pocket deepens,especially in casses where the periodontal pocket depth exceeds 6 mm.This study shows that PGE2 level is significantly related to the severity of bone destruc-tion in periodontitis.
