Purpose: This study was conducted to examine the phase transition according to the zirconia surface treatment. Methods: The specimens were divided to four groups. The first group was sintered at 1,500 and ground; the second group was sintered at 700 , ground, and sintered at 1,500 ; the third group was sintered at 1,500 , ground, and 110 -sandblasted; and the fourth group was sintered at 1,500 , ground, 110 -sandblasted, treated with 9.5% hydrofluoric acid, and ultrasonic cleaner-washed for two minutes. The monoclinic fractions were measured, and the surface was observed via SEM. Results: The monoclinic fraction was 0.13 0.19% in the control group Zr1, 1.91 0.15% in the experimental group Zr2, 7.71 0.34% in Zr3, and 8.39 0.25% in Zr4. On the surface, the phase transition hardly occurred in the control group Zr1, but it increasingly occurred in the experimental groups Zr3 and Zr4. Conclusion: The monoclinic fraction was high in the experimental groups Zr3 and Zr4. The phase transition did not occur in the control group, but increasingly occurred in the experimental
