- Abstract
Objective: Shear bond strength (SBS) of different calcium silicate cements (CSC) with different adhesive systems and restoratives was evaluated., Materials and methods: NeoMTA2, NeoPutty and TheraCalPT were used as CSC.120 acrylic blocks with a hole in the middle were prepared and divided into three groups (n=40) depending on the CSC used. CSCs were placed in the prepared cavities. All groups were divided into two subgroups and adhesives (Prime&BondNT) and Universal adhesive (Scotchbond) were applied. Then, composite (n=10) and compomer (n=10) were applied and polymerized. The prepared samples were kept at 37oC in a 100% humid environment for 24 hours and SBS tests was performed with an universal testing device. Fracture types were evaluated with SEM and stereomicroscope. Results: TheraCalPT had statistically significant increased SBS values when compared to other materials(p<0.05). On the other hand, SBS values of NeoMTA and NeoPutty were insignificant(p>0.05). The difference between the adhesive systems and the restorative materials themselves was not significant (p>0.05). Conclusion: The ease of use of TheraCal PT and its strong bonding ability with resin restorative materials may provide support for the idea that it is suitable for pulp therapies. However, since in vitro environmental conditions do not reflect intraoral conditions, it must be supported by clinical studies to understand the actual performance and clinical usability.
