Which of the following is a cause of reduced salivary flow?

• A. Acute/chronic inflammation of salivary glands
• B. Increased masticatory activity
• C. High fluid intake
• D. Vegetarian diet

Answer: (A)

Reduced salivary flow occurs when the salivary glands aren’t producing or delivering saliva effectively. When the glands become inflamed, whether acutely or chronically, swelling and disruption of the secretory cells along with potential ductal obstruction impair secretion, leading to less saliva being produced and released into the mouth. The other options don’t fit that mechanism: increased chewing actually stimulates saliva via reflexes and tends to raise flow; high fluid intake helps maintain hydration and can support normal saliva production; a vegetarian diet by itself does not directly suppress salivary gland secretion.
