Influence of mechanochemical treatment and oxygen inhibited layer on the adhesion of self-adhesive resin cement to bulk-fill composite resin

Abstract

Objectives: This study evaluated the shear bond strength (SBS) of self-adhesive resin cements (SARC) to bulk-fill composite resins (BFCR) following mechanical and chemical surface treatments. Materials and Methods: The BFCR discs fabricated were divided into four groups, based on the presence or absence oxygen inhibited layer (OIL) and mechanical surface treatment, as follows; group I: OIL+no surface treatment (NT), group II: no OIL+NT, group III: no OIL+diamond abrasive (DA), group IV: no OIL+air abrasion (AA). Each group was further divided into two subgroups based on chemical treatment using a silane agent. Following this, SARC cylinders were bonded to the surfaces of the treated BFCR samples. SBS was evaluated for all samples and failure analysis was carried out. The data were analyzed using independent t-test, one-way ANOVA and post hoc Tukey test, and a p value of <0.05 was set as statistically significant. Results: The highest SBS was recorded in group IV (no OIL+AA) without silane application (25.66±4.49 MPa), while the lowest was observed in group I (OIL+NT) with silane treatment (0.4±0.24 MPa). Mechanical surface treatment succeeded in significantly improving the SBS, while chemical surface treatment using silane application failed to do so. Conclusion: Mechanical surface treatment with air abrasion on the BFCR enhanced its bonding ability with SARC. However, OIL and chemical treatment using a silane agent did not improve the SBS.
