Background/Objectives To evaluate the microtensile bond strength (μTBS) between epoxy-based or dimethacrylate-based fiber posts and resin cores after various post surface treatments. Materials and methods Eighty DT light (DT) and forty FRC Postec Plus (FRC) posts were divided into 8 groups; group 1: silanization (S), group 2: silanization and application of bonding agent (SB), groups 3, 5, 7: etching with 37% phosphoric acid for 1 minute (P), 30% hydrogen peroxide for 10 minutes (H30), 35% hydrogen peroxide for 1 minute (H35), respectively, followed by S, groups 4, 6, 8: etched as in groups 3, 5, and 7, but followed by …
