Abstract
The aim of this investigation was to examine the bonding efficacy of a universal adhesive containing various silane agents to repair aged resin composite with new resin composite. Ninety resin composite specimens were created with nanofilled resin composite and aged for 5000 cycles in a thermocycler. The specimens were sorted into nine groups (n = 10) at random based on the methods used to treat the surfaces with/without silane agent (Si) and adhesive agents (Single bond universal SU; Single bond universal plus SUP; Clearfil Tri-S bond universal CFU; and Single bond 2 SB2). A template was placed on the treated surface of the aged resin composite and then the resin composite was filled into the template. The shear bond strength (SBS) test was conducted using a universal tester and failure patterns were determined. The statistical analysis was performed using a one-way ANOVA and a Tukey抯 test. The lowest SBS values were exhibited in the no surface treatment group (7.69 ? 2.57 MPa). The highest SBS values were exhibited in Si + SUP group (28.04 ? 1.62 MPa) with a significant difference compared to SUP group (22.69 ? 2.21 MPa) Si + SU group (22.08 ? 1.83 MPa) Si + CFU group (21.98 ? 1.54 MPa) and Si + SB2 group (21.85 ? 2.18 MPa). The experimental group demonstrated a predominance of adhesive failure at the junctions between the aged resin composite and the new resin composite. In conclusion The SUP which incorporates 3-(aminopropyl)triethoxysilane (APTES) and 3-methacryloxypropyltriethoxysilane (3-MPTES) has a positive effect on the repaired shear bond strength of resin composite to resin composite both with and without the use of a silane agent prior to the use of the SUP when compared with a conventional adhesive agent (SB2) and other universal adhesives (SU and CFU). Moreover an additional silane agent used prior to the SUP application has the highest shear bond strength. ? 2023 by the authors.
