Saliva Substitutes
Artificial preparations formulated to mimic the lubricating and protective properties of natural saliva, used in the management of salivary gland hypofunction.
Full Definition
Saliva substitutes (also termed artificial saliva or oral moisturisers) are topically applied preparations—available as sprays, gels, or lozenges—designed to alleviate the symptoms of dry mouth (hyposalivation) by replacing or supplementing reduced salivary output. Their formulations may include carboxymethylcellulose, mucin, or xylitol, and some contain fluoride or calcium phosphate for cariostatic benefit. In dental research, particularly studies involving head and neck radiotherapy patients, Sjögren's syndrome cohorts, or elderly populations, saliva substitutes are frequently assessed interventions. Editors must distinguish between saliva substitutes (which replace salivary function) and salivary stimulants (which promote residual gland secretion), as conflation of these categories misrepresents intervention mechanisms. The preferred plural form is 'saliva substitutes', not 'salivary substitutes'.
Usage
Usage note: Use 'saliva substitutes' (not 'salivary substitutes'). Distinguish from 'salivary stimulants' or 'sialogogues', which act on residual gland function rather than replacing secretion.
