LEVELS OF MYELOPEROXIDASE AND CALPROTECTIN IN CREVICULAR FLUID AT DIFFERENT PROBING DEPTHS.

Objectives: Calprotectin (CalP) and myeloperoxidase (MPO) are biochemical markers in the gingival crevicular fluid (GCF). Their increased concentration indicates the onset of an inflammatory process. The aim of this study was to valuate the correlation between the levels of calprotectin and myeloperoxidase detected in the crevicular fluid (GCF) at different probing depth (PPD). Materials and methods: Results: Conclusions: the results of this study indicated that the concentration of calprotectin and myeloperoxidase in the crevicular fluid may be considered reliable qualitative markers of inflammation status (presence/absence of inflammations). The calprotectin is produced not only by neutrophils but also by other cells that can alter the dosage in periodontal pockets. The concentration of myeloperoxidase seems significantly related to the increased presence of neutrophils into the deepest pockets.
