Observations of SnF2-treated human enamel using scanning electron microscope.
Human enamel was ground flat, treated for 4 min with 8 percent SnF2 and then immersed in water for 5 sec, 5 min, 60 min and 24 h. Products formed on the enamel included round globular and triangular-shaped crystalline structures which were removed after the treated enamel specimens were immersed in water for 24 h. In contrast, the non-water-washed treated enamel specimens had a distinct precipitate.
