Abstract: AIM: The aim of this study was to compare and evaluate the phase transformation and effect on the bond strength and fracture toughness of monolithic zirconia after surface treatment with alumina and synthetic diamond particles. MATERIALS AND METHODS: = 20). Pretreatment phase and posttreatment of each zirconia sample from group A and group B were evaluated using an X-ray diffraction machine. The surface roughness of each zirconia sample was evaluated using a profilometer. Composite discs were fabricated and bonded to the air-abraded surface of each zirconia sample from group A and group B using a dual-cured resin cement, respectively. These samples were mounted in an acrylic block to determine the bond strength of zirconia with resin cement using a universal testing machine. This was followed by a fracture toughness test of the samples using a Vickers indentation hardness tester. The results were subjected to statistical analysis using a t-test, and relevant statistical conclusions were drawn. RESULTS: < 0.05 was considered statistically significant. CONCLUSION: The distribution of mean monoclinic content was significantly higher in zirconia samples abraded by alumina (Group A) as compared to synthetic diamond particles (Group B). The mean surface roughness and bond strength results were statistically insignificant between both groups. The distribution of mean fracture toughness was significantly higher in group B compared to group A. CLINICAL SIGNIFICANCE: Synthetic diamond particles for air abrasion of Y-TZP can be a promising alternative to alumina as they cause minimal changes in the structural integrity without compromising the bond strength.
