The antimicrobial properties of saliva are due to
a wide variety of immune and nonimmune salivary
proteins that inhibit the adherence and growth of viruses
and bacteria.8 Salivary proteins and mucins contribute
to the lubrication and coating of oral tissues, protecting
the oral mucosa from chemical, microbial and physical
injuries. Saliva provides moisture to facilitate speech and
taste, and significant loss of salivary gland function is
associated with altered taste sensation (dysgeusia).
