Comparison of push out bond strength of various root perforation repair materials

Abstract

High bond strength of root perforation repair materials is essential for success of endodontic therapy. The aims of current study were to assist the push-out bond strength of 4 types of root perforation repair materials (Biodentine , Mineral trioxide aggregate, glass ionomer cement, and calcium hydroxide paste) from dentin, and to determine the modes of failure at debonded surfaces.
