Effect of Glass Fiber Post Surface Treatment on Bond Strength of a Self-Adhesive Resin Cement: An “In Vitro” Study

Table 1

Glass fiber post surface treatment protocols.

Groups	GFP surface treatment
Control (C)	No surface treatment
Silane (SIL)	Silane layer was applied to the post surface (silane/Dentsply) for 1 minute with the aid of a microbrush (GN/Injecta) following the manufacturer’s recommendations. Later, the adhesive system was applied
Peroxide (PER)	The post surface was immersed in 24% H2O2 solution for 1 minute. Then, they were rinsed with distilled water and dried with air blasts. The adhesive system was then applied
Hydrogen peroxide and silane (PER + SIL)	The post surface was immersed in 24% H2O2 for 1 minute. Then, they were rinsed with distilled water and dried with air blasts. Silane application was made, and then, the adhesive system was applied
Aluminum oxide blasting (BLAST)	The posts were blasted using a blasting machine (Microjato/Gold Line) with aluminum oxide particles of 50 μm (Bio-art) ejected at 1 cm perpendicular to the surface of the post to make superficial microretentions for 5 seconds. The pressure exerted during blasting was 0.3 MPa. The posts were washed with distilled water and dried with air blasts, and then, they received the application of the adhesive system
Aluminum and silane blasting (BLAST + SIL)	Blasting was performed on the post as described above, and then, they were conditioned by the silane and adhesive system (same technique)
