Abstract:

Objective To evaluate the feasibility of preparation of standardized enamel specimens in wear experiment. Methods The standardized enamel specimens were grinded against disc-shaped nickel base cast alloy samples. The mass loss of the standardized enamel specimens was calculated, and the data were statistically analyzed. Results The statistical analysis revealed that the sample size was 36, the average was 58.35, the standard deviation was 3.86, and the coefficient of variation was 6.61. The value of P through test of normality (W test) was 0.742 2, which meant samples from a normal distribution. Conclusion The prepared standardized enamel specimens can be used in wear experiment.
