Lysozyme and lactoferrin quantitation in the crevicular fluid

Area of Science:

• Biochemistry
• Immunology
• Periodontology

Background:

• Periodontal disease diagnosis relies on clinical assessment.
• Biomarkers in crevicular fluid offer potential for objective diagnostic tools.

Purpose of the Study:

• To evaluate the diagnostic utility of lysosomal enzyme levels in gingival crevicular fluid for periodontal disease.
• To determine if lysozyme and lactoferrin quantitation in crevicular fluid can differentiate periodontal conditions.

Main Methods:

• Crevicular fluid (CF) was collected from patients with gingivitis, generalized adult periodontitis, localized juvenile periodontitis, and healthy controls using filter paper strips.
• Lysozyme and lactoferrin concentrations in CF were measured using rocket immunoelectrophoresis.

Main Results:

• Lysozyme levels were significantly elevated in localized juvenile periodontitis patients compared to those with gingivitis and adult periodontitis.
• Lactoferrin levels did not show significant differences across the studied periodontal disease groups.
• The ratio of lysozyme to lactoferrin in CF was notably higher in localized juvenile periodontitis.

Conclusions:

• Lysozyme quantitation in crevicular fluid shows promise as a diagnostic marker for periodontal disease.
• A lysozyme to lactoferrin ratio in crevicular fluid may serve as a valuable diagnostic indicator for localized juvenile periodontitis.
