[Relationship between elastase activity and leukocyte counts in gingival crevicular fluid]
Summary
Elastase (EA) activity in gingival crevicular fluid (GCF) supernatant and pellet correlates with polymorphonuclear leukocyte (PMN) counts. EA in GCF may serve as a valuable marker for PMNs in periodontal pockets.
Area of Science:
- Periodontology
- Biochemistry
Context:
- Gingival crevicular fluid (GCF) contains enzymes and cells relevant to periodontal inflammation.
- Polymorphonuclear leukocytes (PMNs) are key inflammatory cells in periodontal disease.
- Elastase (EA) is a protease released by PMNs.
Purpose:
- To investigate the correlation between elastase activity in GCF supernatant (EA-s) and pellet (EA-p) and PMN counts.
- To assess the utility of EA as a biomarker for PMNs in GCF.
Summary:
- GCF was collected from periodontal pockets using filter paper strips and washings.
- EA levels in the supernatant and pellet were measured separately.
- PMN counts were determined using light microscopy.
Impact:
- A significant positive correlation was found between EA-s, EA-p, and PMN counts in GCF.
- GCF-EA-p effectively reflects the quantity of PMNs in periodontal pockets.
- EA is proposed as a reliable marker for PMNs in GCF, aiding in periodontal diagnostics.
