Popis: Objectives: The aim of this study was to examine the effect of different hardening times and blood contamination of MTA and Biodentine, which are widely used for pulp capping treatments in the market, on shear bond strength (SBS) with a self-etch adhesive resin, after different hardening times (24, 48, 72 and 96 hours). Materials and Methods: Slots with a diameter of 5 mm and a height of 2 mm were prepared in 192 acrylic blocks for this study. Both ProRoot MTA and Biodentine were prepared according to the manufacturer’s instructions, and half of the slots were filled with ProRoot MTA and the other half were filled with Biodentine. All the samples were divided into groups depending on four different hardening times and hardened. After hardening process completed, the group of each hardening time was divided into 2 subgroups (n:12) with and without contamination. In the uncontaminated groups, a self-etch adhesive resin (Clearfil Liner Bond) and a resin-based composite (Filtek P60) were applied on the samples and polymerized. In the contaminated groups, the sample surfaces were contaminated with blood for 20 seconds. After washing and drying the samples, adhesive resin and composite were applied on them. After that SBS tests were performed and the data were subjected to a 2-way ANOVA test analysis. Results: In the uncontaminated groups, there was no significant difference in the SBS of each pulp capping material depending on different hardening times (p>0.05). ProRoot MTA showed statistically higher SBS than Biodentine in the 72 and 96 hour uncontaminated groups (p
