A. Vandenabbeele et al., THE INFLUENCE OF DIFFERENT FLUORIDE SALTS ON FLUORIDE-MEDIATED INHIBITION OF PEROXIDASE-ACTIVITY IN HUMAN SALIVA, Archives of oral biology, 40(8), 1995, pp. 695-698
Fluoride-mediated inhibition of peroxidase potential activity in human
saliva was investigated using NaF, NH4F, CaF2, Na2PO3F (MFP), SnF2 an
d TiF4. At pH 5.5 and for a 20 mM F concentration, the inhibition perc
entages increased from 2% for MFP and 5% for CaF2 to 61% for NaF and 6
5% for NH4F, while a 100% inhibition was observed at 10 mM for TiF4 an
d at 5 mM for SnF2. The inhibition was enhanced at acid pH and removed
at pH 7. The inhibition could be attributed to ionized F-, except for
SnF2 and TiF4, in which part of the inhibition could be imputed to th
e cations.
