Gingival Crevicular Fluid and Placental Tissue Levels of Interleukin-17 as a Possible Marker for Preterm Labor in Patients With Chronic Periodontitis

Ain Shams University40 enrolled

Overview

This case control-study measures the levels of Interleukin-17 in gingival crevicular fluid and placental tissue samples of pregnant females as a possible marker in determining whether or not an association exists between chronic periodontitis and preterm labor. Interleukin-17 is a pro-inflammatory cytokine whose levels have been proven to increase in periodontal disease.
