Matrix Metalloproteinases's in Oral Biofluids During Pregnancy and Postpartum

Modulation of Matrix Metalloproteinases-8, -9 and Endogenous Tissue Inhibitor-1 in Oral Biofluids During Pregnancy and Postpartum

The aim of this study was to investigate salivary and gingival crevicular fluid (GCF) levels of MMP-8, MMP-9 and TIMP-1 during 2/3 trimester of pregnancy and after delivery

MMP-8 and MMP-9 have been reported to reflect the inflammatory status in periodontal tissues and, therefore represent as potential biomarkers of periodontitis. The balance between tissue inhibitors of metalloproteinases (TIMPs) and MMPs play an important role in maintaining the integrity of healthy periodontium.
