Abstract
MMP-13 has been shown to be expressed by periodontitis affected human gingival sulcular epithelium and gingival fibroblasts. Several studies have demonstrated elevated MMP-13 levels in GCF and diseased gingival tissues in chronic periodontitis patients. In addition, increased MMP -13 activity during disease activity has been reported suggesting a role for MMP-13 in periodontal tissue destruction and/or alveolar bone loss.
