Abstract
The bonding between pulp capping materials and overlying restorative materials is a key factor in the success of vital pulp therapy. The introduction of bioactive and resin-based restorative materials has made it important to assess the compatibility with the most used pulp capping materials like TheraCal LC, Bio dentine and Mineral Trioxide Aggregate (MTA). Therefore, it is of interest to compare the shear bond strength of four different restorative materials (Bio-glass restorative glass ionomer cement, fiber reinforced composite, universal croma composite with nano fillers, resin modified glass ionomer cement) bonded to the above pulp capping materials. Acrylic blocks were prepared in total 120 blocks were divided into 12 groups. Shear bond strength tests were conducted on the specimens with a universal testing machine and failure mode analysis was performed under a stereomicroscope. Thus, this data will help clinicians to choose the best combinations of materials for better clinical results.
