Abstract: The microhardness and wear resistance of artificial carious human enamel and artificial carious human enamel applied with two anticarious measures were tested by a sclerometer and a oscillating friction and wear test rig. As the results, artificial carious enamel exhibit a lower hardness and a weaker wear resistance compared with normal enamel. Being treated with NaF can weaken the surface of carious enamel. Moreover, the application of the two anticarious measures can't improve the wear resistance of enamel.
