Salivary flow rate (unstimulated) · Elderly (>60 years) and medically compromised adults with xerostomia / dry mouth
In elderly and medically compromised people with xerostomia, chewing sugar-free gum daily for two or more weeks produces a small but statistically significant increase in unstimulated whole salivary flow rate versus no gum (SMD 0.44, 95% CI 0.22 to 0.66); certainty of evidence was not formally graded.
