The mean value from the two collections was used.
Did not collect UWS to distinguish normosalivators from severe hyposalivators or hyposalivators to compare those values with the secretion values of minor salivary glands.
Mild hyposalivation was considered <0.2 for UWS and 1.0 mL/min for SWS; low whole saliva secretion as <0.2 for UWS and <1.0 mL/min for SWS.
PS: palatal saliva; ULS: upper labial saliva; LLS: lower labial saliva; BMS: buccal mucosal saliva; LMS: lingual mucosal saliva.
aValues are expressed in milliliter per minute (mL/min).
bValues are expressed in microliter per square centimeter per minute (μL/cm2/min); ± standard deviation.
