The effect of ammonium sulfate on the rate of dissolution of human enamel, dentin, and synthetic hydroxylapatite at different pH values was studied. Ammonium sulfate enhanced the dissolution of all the tested materials. The sulfate ion was responsible for the increase in the solubility of powdered dentin at all tested pH values between 4.2 and 7.4.
