ABSTRACT

Introduction: Indirect resin restorations are widely used in the esthetic treatment of posterior teeth. Preheated resins have been recently proposed as luting agents.
Objective: Evaluate the tensile bond strength of indirect restorations cemented with a preheated resin versus a self-adhesive resin cement and a resinous cement.
Methods: Tooth preparation was conducted of 45 premolars using calibrated diamond-coated stones. The samples were randomly divided into three sets (n = 15) according to the following experimental groups: Group 1 (preheated resin), Group 2 (self-adhesive resin) and Group 3 (adhesive resinous cement), and soaked in self-polimerizable acrylic. Indirect restorations were performed for each sample. The inner surfaces were microsanded, and silane was applied before cementation with the luting agents. Tensile bond strength was verified with a universal testing machine at a crosshead speed of 5 mm/min. Statistical analysis was based on one-factor ANOVA and Tukey's post hoc test. A significance level of p < 0.05 was established.
Results: The Filtek Z250 XT resin preheated at 60°C for 15 minutes displayed a tensile bond strength of 5.775 MPa, similar to RelyX Ultimate with 5.442 MPa (p > 0.05). Both groups displayed a significantly greater tensile bond strength than RelyX U200 (3.430 MPa).
Conclusions: The preheated resin (Filtek Z250 XT) and the resinous cement (RelyX Ultimate) exhibit the same tensile bond strength properties when used as luting agents in indirect resin restorations.
