Aim of the study: evaluate and compare shear bond strength of MTA and Bio-Dentin to dentin after one day. Materials and Methods: Thirty upper premolars were selected and sectioned1 mm above the level of pulp horns to expose much dentin, specimens were randomly assigned into three groups, n=10 each. MTA, Bio-Dentin and calcium hydroxide (control) were mixed then filled in tubes [diameter & height = 3mm] then applied on dentin surfaces. After one day, the shear bond strength was tested using a universal testing device. A Stereo microscope was used to assess failure modes. Results: After one day, setting of these capping materials, shear bond strength of MTA and Bio-Dentin were significantly different from that of calcium hydroxide. However, shear bond strength of MTA and Bio-Dentin were not significantly different. Calcium hydroxide showed 100% adhesive failure, Bio-Dentin showed 12% mixed failure while MTA showed 15% mixed failure. Conclusion: After one day setting, MTA and Bio-Dentin showed shear bond strength higher than that of Calcium Hydroxide with some precedence to Bio-Dentin. Keywords: MTA, Bio-Dentin, Shear Bond Strength, Pulp Capping Materials.
