Abstract: Aim: To Compare and evaluate micro shear bond Strength of Self-adhesive resin cement to two commercially available Zirconia-reinforced lithium silicate ceramic. Settings and Design: In vitro evaluative and comparative study. Methods and Material: VITA Suprinity (VS) and Celtra duo (CD) blocks were sectioned into 10 each microbars. Each microbar was cemented to each flat dentin surface of a human premolar with self-adhesive resin cement. micro shear bond strength at 24 hours and after a week was then determined and the data was analysed by using t-test. Statistical analysis used: t-test. Results: The analysis revealed that the type of Zirconia-reinforced lithium silicate ceramic used did not reveal any significant difference in msbs. Conclusions: Within the limitations of this study, the two commercially available ZLS ceramics achieved comparable msbs when they were bonded to dentin by using self adhesive resin cement.
