Abstract
Objectives: This study evaluated the shear bond strength (SBS) of self-adhesive resin cement (SARC) to bulk-fill composite resin (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); and 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, the SARC cylinders were bonded to the surfaces of the treated BFCR samples. SBS was evaluated for all the samples, and failure analysis was carried out. The data were analysed using an independent t-test, one-way ANOVA and post hoc Tukey test and a p value of <0.05 was considered to indicate statistical significance. 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. Conclusions: Mechanical surface treatment via abrasion enhanced the bonding ability of BFCR with SARC. However, OIL and chemical treatment using a silane agent did not improve the SBS.
