Objective: To measure the effect of Non-Thermal Atmospheric Plasma (NTAP) on the push out bond strength of fiber reinforced post luted to root dentin, using two separate luting agents; Multilink (dual cure composite resin) and Glass ionomer cement (GIC). Methodology: 64 extracted human teeth samples were prepared. Root canal treatment was performed, and post space preparation was done in all the samples. This was followed by exposure of half the samples with NTAP and the remaining half samples were not NTAP treated. Fiber post was luted with Multilink composite and GIC to the samples accordingly. Push out bond strength was measured in all the samples under Universal Testing Machine and the values were recorded in Newton. Results: The push out bond strength in all the samples that were surface treated with NTAP was significantly higher than the samples which were not surface treated. In case of luting agents Multilink showed a statistically higher value than GIC and the push out bond strength of all the samples were significantly higher in the coronal one third when compared to middle one third.
