Objective: The purpose of this in vitro study is to evaluate the effect of various surface treatments (STs) and restorative materials on the shear bond strength (SBS) of glass hybrid (GH) restorative materials.

Methods: Sixty-three GH restorative material samples (Equia Forte Fil, GC) were prepared (6 × 2 mm) and randomly divided into 3 groups according to the subsequent ST (n=21): phosphoric acid etching (PA), aluminum oxide sandblasting (AO), and diamond bur roughening (DB). After that, 3 subgroups were created from the samples in each group based on the restoration material applied: Ionofil Molar AC (IM; Voco), Fuji II LC (FLC; GC), and Charisma Smart (CS; Kulzer). The bonded specimens were subjected to the SBS test. In addition, the samples were evaluated with a scanning electron microscopy. The results were statistically examined using twoway analysis of variance with post hoc test (P=.05).

Results: The CS groups were higher in SBS compared to the other groups, whereas the IM groups had low bond strength (P < .05). The FLC, CS, DB, and PA groups showed the highest SBS (P < .05). The lowest SBS values were observed in the PA group in IM (P < .05).

Conclusion: The GH restorative materials were successfully repaired with composite resin using diamond bur roughening or phosphoric acid etching
