    Author(s): Mustafa Hajoori*

    Introduction For a restoration to be successful, one of the key properties of the material is to prevent micro leakage. Even though shelf life of composite resin and bonding agent in an important factor, they can be used for simple procedures even after their expiration date. The aim of the study was to determine the effect on micro leakage of standard and one-year expired composites and bonding agents. Materials and Methods Selected forty specimens were etched for 15 seconds in 37 percent phosphoric acid and randomly divided into four groups: Non-Expired composite and bonding agent; Expired composite and bonding agents; Non-Expired composite and expired bonding agent; Expired composite and Non-Expired bonding agent; and Expired composite and Non-Expired bonding agent. Using a stereomicroscope, specimens were sectioned longitudinally and examined for leakage (dye penetration). Results.. Read More»
