Susceptibility of Oral Bacteria to Various Fluoride Salts

Abstract
Oral microorganisms were tested for their susceptibility to various fluoride salts. SnF2 and CuF2 had a better antimicrobial effect than did NaF and NH4F. Low pH enhanced the bactericidal effect of the fluoride salts. The results indicate that the cariostatic effect of fluoride is not due to a selective bactericidal effect on cariogenic bacteria.
