Abstract

Background and Aims: Reliable bonding between tooth substrate and ZIRCONIA-based ceramic restorations is always of great importance. The LASER might be useful for treatment of ceramic surfaces. The aim of the present study was to investigate the effect of LASER irradiation on the shear bond strength of ZIRCONIA ceramic surface to dentin.Materials and Methods: In this experimental in vitro study, 40 Cercon ZIRCONIA ceramic blocks were fabricated. The surface treatment was performed using sandblasting with 50-micrometer Al2O3, CO2 LASER, or Nd:YAG LASER in each test groups. After that, the specimens were cemented to human dentin with resin cement. The shear bond strength of ceramics to dentin was determined and failure mode of each specimen was analyzed by stereo-microscope and SEM investigations. The data were statistically analyzed by one-way analysis of variance and Tukey multiple comparisons. The surface morphology of one specimen from each group was investigated under SEM.Results: The mean shear bond strength of ZIRCONIA ceramic to dentin was 7.79±3.03, 9.85±4.69, 14.92±4.48 MPa for CO2 irradiated, Nd:YAG irradiated, and sandblasted specimens, respectively. Significant differences were noted between CO2 (P=0.001) and Nd:YAG LASER (P=0.017) irradiated specimens with sandblasted specimens. No significant differences were observed between two LASER methods (P=0.47). The mode of bond failure was predominantly adhesive in test groups (CO2 irradiated specimens: 75%, Nd:YAG irradiated: 66.7%, and sandblasting:41.7%).Conclusion: Under the limitations of the present study, surface treatment of ZIRCONIA ceramics using CO2 and Nd:YAG LASERs was not able to produce adequate bond strength with dentin surfaces in comparison to sandblasting technique. Therefore, the use of LASERs with the mentioned parameters may not be recommended for the surface treatment of Cercon ceramics.
