Study Notes
Saliva as a Diagnostic Fluid
- Saliva is a cost-effective diagnostic tool with real-time values.
- Multiple samples can be obtained easily with less manipulation.
- Saliva composition changes reflect various oral and systemic diseases.
Comparison of Inorganic Compounds
- Saliva has different inorganic compound concentrations compared to plasma.
- Sodium (Na+): Whole unstimulated saliva (5 mmol/l) vs. plasma (145 mmol/l).
- Potassium (K+): Higher in saliva (22 mmol/l) than plasma (4 mmol/l).
- Chloride (Cl−): 15 mmol/l in saliva vs. 120 mmol/l in plasma.
- Calcium (Ca2+): Similar levels in saliva (1-4 mmol/l) compared to plasma (2.2 mmol/l).
Salivary Biomarkers for Diseases
-
Periodontal Disease
