Fluoride in human parotid saliva
I. L. Shannon, R. P. Feller and H. H. Chauncey
Gustatory stimulation was used to collect parotid saliva in an ascending
flow rate pattern. F concentration was found to be independent of rate of
flow. The F level in unstimulated parotid saliva, collected before the
stimulate samplings, was significantly (P less than 0.01) higher than that
for the stimulated collections. It is suggested that this is an apparent
increase based on the movement of water out of the lumen, which is in turn
triggered by sodium reabsorption. The level of F in unstimulated saliva
increased almost tenfold within one hour after the oral administration of
10 mg of F, and a significant (P less than 0.01) increase persisted even at
24 hours after administration of the dosage.
