title: Effects of different pretreatments on the bond strength of a dual-cure resin core material to various fiber-reinforced composite posts.
abstract: The aim of this study was to evaluate the effects of different pretreatments on the bond strength of a dual-cure resin core to 3 types of fiber posts. Bond strength was measured using a push-out design. One-sided t-Test of Hypothesis with unknown variance was performed (p-values < 5%). Sandblasting abrasion with 50 micro alumina particles at a specific distance, pressure and time was the only surface treatment in DT Light Post and Transluma Post that increased the bond strength to dual cure resin composite cores. FRC Postec Plus post did not shown an increase in bond strength in any group.
