A decrease in which salivary property reduces caries risk?
Show answer and explanation
Correct answer: D. Viscosity
Decreased salivary viscosity allows saliva to flow freely, bathing teeth with antimicrobial proteins, calcium, phosphate, and buffers. Decreased protein removes antimicrobial defenses; decreased flow reduces self-cleansing; decreased pH creates a more acidic cariogenic environment.
