ABSTRACT

Objective: ①To detect the concentrations of interleukin 1?(IL 1?) and prostaglandin E 2 (PGE 2) in periapical exudates in the patients with acute or chronic periapical periodontitis; ② To examine their correlations with clinical and radiographic findings of the involved teeth.Methods: The volume of periapical exudates was quantified using the standard paper point sampling method; the concentration of IL 1? and PGE 2 was detected using enzyme linked immunosorbent assay(ELISA) or radioimmunoassay(RIA) in 40 cases with acute and in 40 with chronic periapical periodentitis. Results: ①The volume(?l) of the exudates in the cases with acute periapical periodontitis and chronic were 27.10?15.70 and 3.12?2.88( P
