Light or chemically cured dental composite resins leave a soft, sticky superficial layer upon polymerization. The layer is commonly referred to as Oxygen Inhibited Layer and it is always present when a composite or bonding resin is polymerized in air. For years. it wa s believed that Oxygen Inhibited Layer is required before adding more layers of bonded composite. But reports on how Oxygen Inhibited Layer affects the bond strength have been inconsistent and contradictory. The aim of the present study was to compare the shear bond strengths of composite composite bonded specimens prepared with or without Oxygen Inhibited Layer. The shear bond strengths were tested using Universal Testing Machine. The results of the present study show that the presence of Oxygen inhibited layer increases the shear bond strength values at the interphase of incrementally built 2 layer composite specimens. Within the limitations of the present study, it can be conclusively stated "a higher shear bond strength results from Oxygen Inhibition on the surface layer of composite".
