Abstract

Introduction: MTA and Biodentine are the materials used as a retrograde filling, in perforation repair and as pulp-capping materials. The success of pulp-capping agent depends on restorative material that is used over it which provides improved coronal seal. Hence, material placed over MTA & Biodentine as a final restoration should plays a vital role. Immediate placement of composite resin over MTA & Biodentine to decrease appointment is the necessity of hour. So, we are evaluating bond strength of immediately placed composite resin with MTA & Biodentine. Aim: To compare and evaluate bond strength of composite resin with MTA & Biodentine. Methodology: Thirty samples were prepared and divided into 2 major groups – group 1 and group 2, each group contains 15 samples. They were designated for restoring composite resin over MTA & Biodentine with bonding resin respectively after 10 minutes. The samples were mounted in a square metal jig fill with auto cure acrylic resin. The samples were thermocycled for 48 hrs. The shear bond strength was determined using universal testing machine at 1mm/min speed. Result: Composite resin–MTA groups showed significantly higher Shear Bond Strength values than the group made of Composite resin–Biodentine (P
