12. The Role of Saliva: More Than Just Digestive Aid
Saliva plays a multifaceted role in the human body, a fact often overlooked. Beyond aiding in digestion and oral hygiene, it also has antibacterial properties. Enzymes in saliva can break down food particles and inhibit bacterial growth, thus indirectly contributing to the health of the parotid glands.
But here’s the catch: if the quality or quantity of saliva is compromised, as can happen in conditions like Sjogren’s syndrome, the risk for parotitis increases. A decrease in saliva can lead to a more conducive environment for bacterial growth.
Interestingly, saliva can also be a diagnostic tool. Analysis of salivary composition can help identify issues within the parotid gland or even serve as a marker for systemic diseases, offering clues that go beyond oral health.(12)
